Methods A total of 30 healthy male volunteers aged 20-35 years participated in the study. Participants were randomly assigned to myofibrillar (n=15) and sarcoplasmic (n=15) hypertrophy training groups. The study employed a pretest-posttest design over eight weeks of myofibrillar and sarcoplasmic training. Anthropometric measurements included height, weight, body mass index (BMI), and circumferences of the shoulder, chest, waist, upper arm, and thigh. Pectoralis major (PM), latissimus dorsi (LD), and quadriceps femoris (QF) muscle thickness were measured using ultrasonography. Strength measurements included bench press, squat, and deadlift 1 RM before and after training. Paired sample t-tests were used to compare pre-test and post-test data within groups, while independent sample t-tests were used to compare differences between groups. Results were evaluated at a 95% confidence interval and 0.05 significance level. Results Significant differences were observed in the pretest-posttest ultrasound data difference means of the dominant side PM (t = -2.321 p < .05) and LD (t = -2.699 p < .05) muscles between the myofibrillar and sarcoplasmic hypertrophy training groups. Significant differences were also found in the non-dominant side PM (t = -2.352 p < .05) and LD (t = -2.723 p < .05) muscles. Myofibrillar training group showed significant improvements in bench press (t = -9.431 p < .05), squat (t = -2.477 p < .05), and deadlift strength (t = -5.041 p < .05), while the sarcoplasmic group showed significant improvements in bench press (t = -3.287 p < .05) and deadlift strength (t = -2.779 p < .05) in the pretest-posttest. Conclusion Myofibrillar hypertrophy training resulted in greater hypertrophy compared to sarcoplasmic training according to muscle ultrasonography images. Muscle hypertrophy training modalities skeletal muscle adaptation strength training Figures Figure 1 1. Introduction Skeletal muscle hypertrophy is primarily regulated by complex cellular and molecular mechanisms, including mechanical tension, metabolic stress, and muscle damage, which activate intracellular pathways that mediate protein synthesis and fibre growth. Two primary mechanisms myofibrillar hypertrophy, characterized by an increase in contractile proteins (actin and myosin), and sarcoplasmic hypertrophy, associated with the expansion of noncontractile components (e.g., sarcoplasmic reticulum, glycogen, and cytoplasmic volume) differ in their structural and functional outcomes [ 1 ]. Understanding these fundamental mechanisms is essential for distinguishing how specific training methods develop different types of hypertrophy and, consequently, strength and functional outcomes. Exercise has become a part of human history and continues to evolve as a constantly changing activity. Exercise impacts muscle strength by causing microdamage to muscle fibres, initiating the process of muscle repair and growth (hypertrophy) [ 2 ]. There is a positive relationship between hypertrophy and strength. The pursuit of increasing lean body mass is commonly followed by those engaged in weight training. Considering the strong correlation between muscle cross-sectional area and muscle strength, increasing muscle mass is a primary goal for athletes involved in strength and power sports [ 3 ]. Muscle mass is also vital for the sport of bodybuilding, where competitors are judged based on the amount and quality of their muscle development. On a more general level, muscle hypertrophy is pursued by many recreational athletes who want to maximize their physiques [ 4 ]. Thus, maximizing muscle mass has broad ranging impacts on various populations related to sports and health. While muscle hypertrophy can be achieved through a wide variety of resistance training programs, the principle of training specificity suggests that some routines will promote more hypertrophy than others. However, research on the best approach to achieve this goal is lacking. Bodybuilders often train with moderate loads and very short rest intervals, leading to high metabolic stress. In contrast, powerlifters typically train with high intensity loads and long rest periods between sets [ 3 ]. Although both groups exhibit impressive muscle development, it is unclear which method is superior for maximizing hypertrophic gains or whether other training methods might be even better. Skeletal muscle fibres are multinucleated cells containing mostly myofibrils suspended in a watery environment called the sarcoplasm. Literature reviews indicate that sarcoplasmic hypertrophy or the disproportionate enlargement of the sarcoplasm compared to the accumulation of myofibrillar proteins coincides with muscle fibre or tissue growth during resistance training [ 5 ]. Additionally, there is evidence supporting other modes of hypertrophy occurring during resistance training periods, such as the accumulation of myofibrillar protein proportionate to or preceding muscle fibre or tissue growth [ 6 ]. Methods used to investigate these hypertrophy modes are debated. Current hypertrophic training methods emphasize sarcoplasmic and myofibrillar hypertrophy. Sarcoplasmic hypertrophy is typically associated with high-repetition, low-weight exercises, whereas myofibrillar hypertrophy is associated with low-repetition, high-weight strength training. Both types of hypertrophy methods can increase muscle strength and mass [ 7 ]. This study aimed to investigate the effects of myofibrillar and sarcoplasmic hypertrophy training on muscle hypertrophy, strength, and selected anthropometric characteristics. The hypothesis posits that myofibril and sarcoplasmic hypertrophy training have different effects on muscle development, hypertrophy and muscle strength. The confirmation of this hypothesis would provide important contributions to sports scientists, coaches and athletes, especially in strength training methods. 2. Materials and Methods This randomized controlled experimental study with a pretest-posttest design was conducted to compare the effects of myofibrillar and sarcoplasmic hypertrophy training on muscle hypertrophy, strength and selected anthropometric characteristics over a period of six weeks, with sessions held three times a week (18 sessions in total) in a specialized fitness centre and in the laboratories of Ordu University. The study commenced following the approval of the Ordu University Clinical Research Ethics Committee (Date: 07.07.2023, No: 14, Decision: 184). 2.1. Participants A total of 30 healthy male volunteers aged 20–35 years participated in the study. Participants who agreed to participate and signed the informed consent form were randomly assigned to 15 myofibrillar (age: 25.13 ± 5.56 years, weight: 83.95 ± 13.18 kg, height: 178.10 ± 7.42 cm, BMI: 26.42 ± 3.58 kg/m²) and 15 sarcoplasmic (age: 25.41 ± 5.90 years, weight: 83.91 ± 14.31 kg, height: 177.37 ± 7.56 cm, BMI: 26.61 ± 3.82 kg/m²) hypertrophy training groups. Inclusion Criteria: • No previous participation in strength training • Possession of a medical report confirming no contraindications for exercise • No joint injuries in the past six months • No contraindications for performing exercises targeting core muscle groups • Abstinence from caffeine or stimulants on training days • Voluntary participation and approval of the informed consent form Participants who did not meet the inclusion criteria were excluded from the study. 2.2. Data Collection Tools The study employed a pretest-posttest design to observe the effects of eight weeks of myofibrillar and sarcoplasmic training. Anthropometric measurements included height (m) (Holtain Ltd., UK), weight (kg) (model TBF-305; Tanita, Arlington Heights, IL), BMI (kg/m²), and circumferences of the shoulder, chest, waist, dominant upper arm, and thigh. Measurements were taken by an expert using a tape measure with 0.01 cm precision according to ISAK standards. Anthropometric measurements were recorded in centimetres. Pectoralis major (PM), latissimus dorsi (LD), and quadriceps femoris (QF) muscle thickness were measured by an experienced physician at Ordu University Department of Internal Medicine, Department of Radiology using an ultrasonography device (Hi-tachi HiVision Preirus, Tokyo/Japan). Measurements were taken while participants were lying in a comfortable supine position, with the ultrasound probe applied perpendicularly to the muscle without pressure. Ultrasound measurements were recorded in millimetres. 2.3. Training Programs While hypertrophic adaptations are typically observed over longer periods, previous studies have shown that measurable changes in muscle thickness and strength can occur even within short-term interventions. For instance: In our study, both ultrasound and circumferential measurements confirmed statistically significant increases in muscle thickness and strength, supporting the sufficiency of the 6-week period for detecting hypertrophic changes [ 8 , 9 ]. The training protocols used in our study were developed by adapting principles and intensity ranges discussed in prior literature, including Schoenfeld et al. [ 10 ] and Bernárdez-Vázquez et al. [ 11 ], which provide evidence-based guidance on training variables (intensity, volume, rest) for optimizing either myofibrillar or sarcoplasmic hypertrophy. Although no single study presents identical programs, the current protocols were structured in consultation with certified strength coaches and based on the training volume load distinctions commonly accepted in the field: Myofibrillar hypertrophy: Heavy loads (70–90% 1RM), low repetitions (6–8), longer rest (90–120 sec). Sarcoplasmic hypertrophy: Moderate loads (40–60% 1RM), high repetitions (15–20), moderate rest intervals (90–120 sec). The one-repetition maximum (1RM) values of the participants were determined prior to the first training session using standard 1RM testing procedures. To ensure accurate load progression, 1RM values were reassessed biweekly throughout the six-week intervention, and training loads were adjusted accordingly. 2.3.1. Myofibrillar Hypertrophy Training Program Participants in the myofibrillar training group followed an 18-session program over six weeks, with sessions focusing on legs, push, and pull exercises (Table 1 ). Participants attended leg, push, and pull training sessions on separate days each week.

The normality of the data distribution was assessed using the Shapiro-Wilk test. Since the data met the assumptions of normality, parametric statis-tical methods were applied. Paired sample t-tests were used to compare pre- and post-intervention measurements within each group, while independent sample t-tests were used to compare differences between the myofibrillar and sarcoplasmic hyper-trophy training groups. Statistical analyses were conducted using SPSS version 22.0 (IBM Corp., Armonk, NY, USA), and the significance level was set at p < 0.05. 3. Results No significant differences were found in the pretest circumference measurements of the shoulder, chest, upper arm, waist, and thigh regions between the myofibrillar and sarcoplasmic hypertrophy training groups (p > 0.05 for all comparisons).

Discussion This study aimed to measure the hypertrophy ratio of the pectoralis major, latissimus dorsi, and quadriceps muscles following six weeks of training, focusing on sarcoplasmic and myofibrillar hypertrophy. The results indicate that both training types provided similar hypertrophic gains, but the myofibrillar hypertrophy group exhibited greater hypertrophy in the pectoralis major, latissimus dorsi, and quadriceps muscles compared to the sarcoplasmic hypertrophy group after six weeks. The results of the study, which demonstrated significantly greater increases in muscle thickness and strength in the myofibrillar hypertrophy group, can be better understood when considering molecular and cellular mechanisms. Myofibrillar hyper-trophy is associated with the addition of contractile proteins such as actin and myosin, leading to an increase in sarcomere number and muscle fibre diameter. This process is primarily regulated by the activation of mechanotransduction pathways, especially the mTOR signalling cascade, which stimulates protein synthesis following high-intensity mechanical loading. In contrast, sarcoplasmic hypertrophy is characterized by an increase in non-contractile elements such as glycogen, sarcoplasmic fluid, and mitochondrial density, often induced by metabolic stress from high-repetition training. While both types of hypertrophy contribute to muscle growth, the greater strength improvements observed in the myofibrillar group align with the structural enhancements at the level of the contractile machinery. These findings suggest that molecular adaptations induced by high-load training may be more functionally advantageous for performance improvements. Resistance training is recommended as an effective method to increase muscle mass, strength, and power [ 12 ]. Proper control of variables such as intensity, volume, and frequency is crucial when designing exercise programs. These variables influence the adaptation process of muscles and should be carefully managed to optimize muscle development [ 13 ]. Training frequency, a critical variable, refers to the number of training sessions performed within a specified time frame [ 14 ]. Training frequency is often related to the number of sessions targeting specific muscle groups within a given period concerning inducing muscle hypertrophy [ 15 ]. Studies examining the effects of strength training on different muscle groups have shown positive effects on muscle strength and thickness, particularly in the biceps brachii, triceps, vastus lateralis, vastus medialis, and pectoralis muscles. These studies have demonstrated that strength training positively impacts both power and size across different age groups. Training targeting different muscle groups, such as the biceps brachii, triceps, vastus lateralis, vastus medialis, and pectoralis, contributes to muscle strengthening and growth [ 16 , 17 ]. These studies have evaluated the effects of strength training on various muscle groups and provided specific findings. For in-stance, a study investigating the effects of low-intensity strength training (around 30% of maximum strength) on the pectoralis and triceps muscle groups found that this training increased the strength and thickness of both muscle groups over two weeks [ 18 ]. Another study examined the effects of strength training on muscle hypertrophy in the biceps brachii, showing that this training led to increased hypertrophy and oxygen saturation in the biceps muscle [ 19 ] Another study evaluated the effects of an eight-week strength training program on biceps muscle thickness, finding a 11–13% increase in biceps brachii thickness over eight weeks, indicating significant hypertrophy due to strength training [ 20 ]. A study by Kim et al. [ 21 ] conducted on 18 sedentary individuals comparing strength and thickness changes between strength training and moderate-intensity strength training, finding similar increases in strength and thickness in both groups. In our study, significant differences were found in the pretest-posttest ultrasound values of the dominant side PM, LD, and QF muscles. Differences were also found in the pretest-posttest ultrasound values of the non-dominant side PM, LD, and QF muscles. Additionally, significant differences were observed in the pretest-posttest circumference values of the shoulder, chest, upper arm, waist, and thigh regions. These results suggest that both light and heavy loads can support hyper-trophy, but heavy loads are more effective for strength gains. The choice of load when designing training programs is crucial for achieving targeted results. McDonald & Bond [ 22 ] noted that bodybuilders have long experienced muscle growth with high-repetition and short-rest training, resulting in a "pump." However, individuals training with heavy loads tend to have denser muscle fibres, maintaining acute changes in sarcoplasm or fluid within or around the muscles for longer, thus preserving muscle size. Some trainers (mainly from Eastern Europe and Russia) differentiate this as "functional" and "non-functional" hypertrophy. They argue that true strength requires a focus on increasing myofibrillar proteins, termed "functional hypertrophy." In contrast, sarcoplasmic hypertrophy may cause visual growth but does not contribute to performance, termed "non-functional hypertrophy." Haun et al. [ 6 ] provided a clearer perspective, emphasizing that sarcoplasmic hypertrophy is as significant as myofibrillar hypertrophy for muscle development. This underscores the importance of sarcoplasmic hypertrophy, demonstrating its effectiveness comparable to myofibrillar hypertrophy. While the six-week intervention period may appear relatively short, previous studies have demonstrated measurable hypertrophic responses within a similar timeframe using comparable training protocols. For example, Yasuda et al. [ 18 ] re-ported significant increases in muscle cross-sectional area after six weeks of low-load, high-volume resistance training with blood flow restriction—conditions known to promote sarcoplasmic hypertrophy. Similarly, Schoenfeld et al. [ 23 ] observed muscle thickness improvements following six weeks of resistance training at different repetition ranges, noting early-phase hypertrophy attributable to fluid accumulation and metabolic stress. Haun et al. [ 6 ] further emphasized that sarcoplasmic expansion can occur rapidly in response to high-volume training, although sustained structural changes may require longer durations. These findings support the notion that meaningful hypertrophic changes, both sarcoplasmic and myofibrillar, can be observed in short-term interventions, especially in untrained or recreational populations, aligning with the outcomes of the current study. Initial discussions on sarcoplasmic hypertrophy questioned its existence, but sub-sequent studies shifted the focus to its functionality. While quality studies and expert opinions suggest that heavy-load training triggers adaptations contributing to strength gains, other studies and expert opinions indicate that high-repetition training may preferentially stimulate sarcoplasmic hypertrophy. Meijer et al. [ 24 ] compared muscle fibres of bodybuilders, American football players, track and field athletes, and weightlifters. Findings indicated that bodybuilders had larger muscle fibres than other groups. While bodybuilders produced more force than non-competitive individuals, they generated slightly less force than weightlifters. Notably, bodybuilders generated less force per cross-sectional area of muscle compared to other groups. This apparent contradiction suggests that while bodybuilders' individual muscle fibres generate force comparable to weightlifters, their overall force production per muscle cross-sectional area is lower. Thus, despite higher muscular hypertrophy in bodybuilders, their force production per muscle unit is lower. As muscle volume increases, the force produced per muscle unit decreases, indicating that non-functional hypertrophy does not con-tribute to strength. Schoenfeld et al. [ 25 ] highlighted the role of sarcoplasmic hyper-trophy in muscle hypertrophy, associating it with increases in non-contractile proteins and fluids within muscle cells. However, they noted that the exact role of sarcoplasmic hypertrophy in muscle growth remains unclear, requiring further research for definitive conclusions. This study has certain limitations that should be acknowledged. First, the relatively short duration (six weeks) may not fully capture long-term structural adaptations, especially for advanced stages of myofibrillar hypertrophy. Second, the participant group consisted solely of healthy young men with no prior resistance training experience, which may limit the generalizability of the findings to other populations such as women, older adults, or trained athletes. Additionally, although ultrasonography is a reliable method for assessing muscle thickness, it may not detect subtle intracellular changes associated with sarcoplasmic expansion. Future studies should consider long-er intervention periods, include diverse populations, and employ more direct techniques such as muscle biopsy to investigate underlying cellular mechanisms. 5. Conclusions In conclusion, six weeks of myofibrillar and sarcoplasmic hypertrophy training resulted in significant muscle hypertrophy in the pectoralis major, latissimus dorsi, and quadriceps femoris muscles. Myofibrillar hypertrophy training led to greater in-creases in both muscle thickness and strength compared to sarcoplasmic hypertrophy training. Although both methods induced measurable adaptations, the myofibrillar group demonstrated more pronounced improvements across ultrasound and strength parameters, thereby confirming the initial study objectives.

Introduction","content":"\u003cp\u003eSkeletal muscle hypertrophy is primarily regulated by complex cellular and molecular mechanisms, including mechanical tension, metabolic stress, and muscle damage, which activate intracellular pathways that mediate protein synthesis and fibre growth. Two primary mechanisms myofibrillar hypertrophy, characterized by an increase in contractile proteins (actin and myosin), and sarcoplasmic hypertrophy, associated with the expansion of noncontractile components (e.g., sarcoplasmic reticulum, glycogen, and cytoplasmic volume) differ in their structural and functional outcomes [\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]. Understanding these fundamental mechanisms is essential for distinguishing how specific training methods develop different types of hypertrophy and, consequently, strength and functional outcomes. Exercise has become a part of human history and continues to evolve as a constantly changing activity. Exercise impacts muscle strength by causing microdamage to muscle fibres, initiating the process of muscle repair and growth (hypertrophy) [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e]. There is a positive relationship between hypertrophy and strength. The pursuit of increasing lean body mass is commonly followed by those engaged in weight training. Considering the strong correlation between muscle cross-sectional area and muscle strength, increasing muscle mass is a primary goal for athletes involved in strength and power sports [\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e]. Muscle mass is also vital for the sport of bodybuilding, where competitors are judged based on the amount and quality of their muscle development. On a more general level, muscle hypertrophy is pursued by many recreational athletes who want to maximize their physiques [\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e]. Thus, maximizing muscle mass has broad ranging impacts on various populations related to sports and health. While muscle hypertrophy can be achieved through a wide variety of resistance training programs, the principle of training specificity suggests that some routines will promote more hypertrophy than others. However, research on the best approach to achieve this goal is lacking. Bodybuilders often train with moderate loads and very short rest intervals, leading to high metabolic stress. In contrast, powerlifters typically train with high intensity loads and long rest periods between sets [\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e]. Although both groups exhibit impressive muscle development, it is unclear which method is superior for maximizing hypertrophic gains or whether other training methods might be even better. Skeletal muscle fibres are multinucleated cells containing mostly myofibrils suspended in a watery environment called the sarcoplasm. Literature reviews indicate that sarcoplasmic hypertrophy or the disproportionate enlargement of the sarcoplasm compared to the accumulation of myofibrillar proteins coincides with muscle fibre or tissue growth during resistance training [\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e]. Additionally, there is evidence supporting other modes of hypertrophy occurring during resistance training periods, such as the accumulation of myofibrillar protein proportionate to or preceding muscle fibre or tissue growth [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e]. Methods used to investigate these hypertrophy modes are debated.\u003c/p\u003e \u003cp\u003eCurrent hypertrophic training methods emphasize sarcoplasmic and myofibrillar hypertrophy. Sarcoplasmic hypertrophy is typically associated with high-repetition, low-weight exercises, whereas myofibrillar hypertrophy is associated with low-repetition, high-weight strength training. Both types of hypertrophy methods can increase muscle strength and mass [\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThis study aimed to investigate the effects of myofibrillar and sarcoplasmic hypertrophy training on muscle hypertrophy, strength, and selected anthropometric characteristics.

Data Collection Tools\u003c/h2\u003e \u003cp\u003eThe study employed a pretest-posttest design to observe the effects of eight weeks of myofibrillar and sarcoplasmic training. Anthropometric measurements included height (m) (Holtain Ltd., UK), weight (kg) (model TBF-305; Tanita, Arlington Heights, IL), BMI (kg/m\u0026sup2;), and circumferences of the shoulder, chest, waist, dominant upper arm, and thigh.

Anthropometric measurements were recorded in centimetres.\u003c/p\u003e \u003cp\u003ePectoralis major (PM), latissimus dorsi (LD), and quadriceps femoris (QF) muscle thickness were measured by an experienced physician at Ordu University Department of Internal Medicine, Department of Radiology using an ultrasonography device (Hi-tachi HiVision Preirus, Tokyo/Japan). Measurements were taken while participants were lying in a comfortable supine position, with the ultrasound probe applied perpendicularly to the muscle without pressure.

Training Programs\u003c/h2\u003e \u003cp\u003eWhile hypertrophic adaptations are typically observed over longer periods, previous studies have shown that measurable changes in muscle thickness and strength can occur even within short-term interventions. For instance: In our study, both ultrasound and circumferential measurements confirmed statistically significant increases in muscle thickness and strength, supporting the sufficiency of the 6-week period for detecting hypertrophic changes [\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e, \u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThe training protocols used in our study were developed by adapting principles and intensity ranges discussed in prior literature, including Schoenfeld et al.

exercises between the myofibrillar and sarcoplasmic training groups. These differences favor the myofibrillar group (Table\u0026nbsp;\u003cspan refid=\"Tab17\" class=\"InternalRef\"\u003e17\u003c/span\u003e).\u003c/p\u003e"},{"header":"4. Discussion","content":"\u003cp\u003eThis study aimed to measure the hypertrophy ratio of the pectoralis major, latissimus dorsi, and quadriceps muscles following six weeks of training, focusing on sarcoplasmic and myofibrillar hypertrophy. The results indicate that both training types provided similar hypertrophic gains, but the myofibrillar hypertrophy group exhibited greater hypertrophy in the pectoralis major, latissimus dorsi, and quadriceps muscles compared to the sarcoplasmic hypertrophy group after six weeks.\u003c/p\u003e \u003cp\u003eThe results of the study, which demonstrated significantly greater increases in muscle thickness and strength in the myofibrillar hypertrophy group, can be better understood when considering molecular and cellular mechanisms. Myofibrillar hyper-trophy is associated with the addition of contractile proteins such as actin and myosin, leading to an increase in sarcomere number and muscle fibre diameter. This process is primarily regulated by the activation of mechanotransduction pathways, especially the mTOR signalling cascade, which stimulates protein synthesis following high-intensity mechanical loading. In contrast, sarcoplasmic hypertrophy is characterized by an increase in non-contractile elements such as glycogen, sarcoplasmic fluid, and mitochondrial density, often induced by metabolic stress from high-repetition training. While both types of hypertrophy contribute to muscle growth, the greater strength improvements observed in the myofibrillar group align with the structural enhancements at the level of the contractile machinery. These findings suggest that molecular adaptations induced by high-load training may be more functionally advantageous for performance improvements.\u003c/p\u003e \u003cp\u003eResistance training is recommended as an effective method to increase muscle mass, strength, and power [\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e]. Proper control of variables such as intensity, volume, and frequency is crucial when designing exercise programs. These variables influence the adaptation process of muscles and should be carefully managed to optimize muscle development [\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e]. Training frequency, a critical variable, refers to the number of training sessions performed within a specified time frame [\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e]. Training frequency is often related to the number of sessions targeting specific muscle groups within a given period concerning inducing muscle hypertrophy [\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eStudies examining the effects of strength training on different muscle groups have shown positive effects on muscle strength and thickness, particularly in the biceps brachii, triceps, vastus lateralis, vastus medialis, and pectoralis muscles. These studies have demonstrated that strength training positively impacts both power and size across different age groups. Training targeting different muscle groups, such as the biceps brachii, triceps, vastus lateralis, vastus medialis, and pectoralis, contributes to muscle strengthening and growth [\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e, \u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e]. These studies have evaluated the effects of strength training on various muscle groups and provided specific findings. For in-stance, a study investigating the effects of low-intensity strength training (around 30% of maximum strength) on the pectoralis and triceps muscle groups found that this training increased the strength and thickness of both muscle groups over two weeks [\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e]. Another study examined the effects of strength training on muscle hypertrophy in the biceps brachii, showing that this training led to increased hypertrophy and oxygen saturation in the biceps muscle [\u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e] Another study evaluated the effects of an eight-week strength training program on biceps muscle thickness, finding a 11\u0026ndash;13% increase in biceps brachii thickness over eight weeks, indicating significant hypertrophy due to strength training [\u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e]. A study by Kim et al. [\u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e] conducted on 18 sedentary individuals comparing strength and thickness changes between strength training and moderate-intensity strength training, finding similar increases in strength and thickness in both groups. In our study, significant differences were found in the pretest-posttest ultrasound values of the dominant side PM, LD, and QF muscles. Differences were also found in the pretest-posttest ultrasound values of the non-dominant side PM, LD, and QF muscles. Additionally, significant differences were observed in the pretest-posttest circumference values of the shoulder, chest, upper arm, waist, and thigh regions. These results suggest that both light and heavy loads can support hyper-trophy, but heavy loads are more effective for strength gains. The choice of load when designing training programs is crucial for achieving targeted results. McDonald \u0026amp; Bond [\u003cspan citationid=\"CR22\" class=\"CitationRef\"\u003e22\u003c/span\u003e] noted that bodybuilders have long experienced muscle growth with high-repetition and short-rest training, resulting in a \"pump.\" However, individuals training with heavy loads tend to have denser muscle fibres, maintaining acute changes in sarcoplasm or fluid within or around the muscles for longer, thus preserving muscle size. Some trainers (mainly from Eastern Europe and Russia) differentiate this as \"functional\" and \"non-functional\" hypertrophy. They argue that true strength requires a focus on increasing myofibrillar proteins, termed \"functional hypertrophy.\" In contrast, sarcoplasmic hypertrophy may cause visual growth but does not contribute to performance, termed \"non-functional hypertrophy.\" Haun et al. [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e] provided a clearer perspective, emphasizing that sarcoplasmic hypertrophy is as significant as myofibrillar hypertrophy for muscle development. This underscores the importance of sarcoplasmic hypertrophy, demonstrating its effectiveness comparable to myofibrillar hypertrophy.\u003c/p\u003e \u003cp\u003eWhile the six-week intervention period may appear relatively short, previous studies have demonstrated measurable hypertrophic responses within a similar timeframe using comparable training protocols. For example, Yasuda et al. [\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e] re-ported significant increases in muscle cross-sectional area after six weeks of low-load, high-volume resistance training with blood flow restriction\u0026mdash;conditions known to promote sarcoplasmic hypertrophy. Similarly, Schoenfeld et al. [\u003cspan citationid=\"CR23\" class=\"CitationRef\"\u003e23\u003c/span\u003e] observed muscle thickness improvements following six weeks of resistance training at different repetition ranges, noting early-phase hypertrophy attributable to fluid accumulation and metabolic stress. Haun et al. [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e] further emphasized that sarcoplasmic expansion can occur rapidly in response to high-volume training, although sustained structural changes may require longer durations. These findings support the notion that meaningful hypertrophic changes, both sarcoplasmic and myofibrillar, can be observed in short-term interventions, especially in untrained or recreational populations, aligning with the outcomes of the current study.\u003c/p\u003e \u003cp\u003eInitial discussions on sarcoplasmic hypertrophy questioned its existence, but sub-sequent studies shifted the focus to its functionality. While quality studies and expert opinions suggest that heavy-load training triggers adaptations contributing to strength gains, other studies and expert opinions indicate that high-repetition training may preferentially stimulate sarcoplasmic hypertrophy. Meijer et al. [\u003cspan citationid=\"CR24\" class=\"CitationRef\"\u003e24\u003c/span\u003e] compared muscle fibres of bodybuilders, American football players, track and field athletes, and weightlifters. Findings indicated that bodybuilders had larger muscle fibres than other groups. While bodybuilders produced more force than non-competitive individuals, they generated slightly less force than weightlifters. Notably, bodybuilders generated less force per cross-sectional area of muscle compared to other groups. This apparent contradiction suggests that while bodybuilders' individual muscle fibres generate force comparable to weightlifters, their overall force production per muscle cross-sectional area is lower. Thus, despite higher muscular hypertrophy in bodybuilders, their force production per muscle unit is lower. As muscle volume increases, the force produced per muscle unit decreases, indicating that non-functional hypertrophy does not con-tribute to strength. Schoenfeld et al. [\u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e25\u003c/span\u003e] highlighted the role of sarcoplasmic hyper-trophy in muscle hypertrophy, associating it with increases in non-contractile proteins and fluids within muscle cells. However, they noted that the exact role of sarcoplasmic hypertrophy in muscle growth remains unclear, requiring further research for definitive conclusions.\u003c/p\u003e \u003cp\u003eThis study has certain limitations that should be acknowledged. First, the relatively short duration (six weeks) may not fully capture long-term structural adaptations, especially for advanced stages of myofibrillar hypertrophy. Second, the participant group consisted solely of healthy young men with no prior resistance training experience, which may limit the generalizability of the findings to other populations such as women, older adults, or trained athletes. Additionally, although ultrasonography is a reliable method for assessing muscle thickness, it may not detect subtle intracellular changes associated with sarcoplasmic expansion. Future studies should consider long-er intervention periods, include diverse populations, and employ more direct techniques such as muscle biopsy to investigate underlying cellular mechanisms.\u003c/p\u003e"},{"header":"5. Conclusions","content":"\u003cp\u003eIn conclusion, six weeks of myofibrillar and sarcoplasmic hypertrophy training resulted in significant muscle hypertrophy in the pectoralis major, latissimus dorsi, and quadriceps femoris muscles. Myofibrillar hypertrophy training led to greater in-creases in both muscle thickness and strength compared to sarcoplasmic hypertrophy training. Although both methods induced measurable adaptations, the myofibrillar group demonstrated more pronounced improvements across ultrasound and strength parameters, thereby confirming the initial study objectives.\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eFunding\u003c/strong\u003e This research received no external funding.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstitutional Review Board Statement\u003c/strong\u003e The study was conducted in accordance with the Decla-ration of Helsinki and approved by the Institutional Ethics Committee of Ordu University (Date: 07.07.2023, No: 14, Decision: 184) for studies involving humans.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eAcknowledgments\u003c/strong\u003e We would like to thank all the subjects who volunteered their time to participate in this study.

Participants were randomly assigned to myofibrillar (n=15) and sarcoplasmic (n=15) hypertrophy training groups. The study employed a pretest-posttest design over eight weeks of myofibrillar and sarcoplasmic training. Anthropometric measurements included height, weight, body mass index (BMI), and circumferences of the shoulder, chest, waist, upper arm, and thigh. Pectoralis major (PM), latissimus dorsi (LD), and quadriceps femoris (QF) muscle thickness were measured using ultrasonography. Strength measurements included bench press, squat, and deadlift 1 RM before and after training. Paired sample t-tests were used to compare pre-test and post-test data within groups, while independent sample t-tests were used to compare differences between groups. Results were evaluated at a 95% confidence interval and 0.05 significance level.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eResults\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eSignificant differences were observed in the pretest-posttest ultrasound data difference means of the dominant side PM (t = -2.321 p \u0026lt; .05) and LD (t = -2.699 p \u0026lt; .05) muscles between the myofibrillar and sarcoplasmic hypertrophy training groups.
