Effect of an Adapted Exercise Program on Body Composition and Fitness Level in Overweight and Obese Young Women

Background: /Objectives: Individuals with overweight or obesity often experience challenges in achieving daily physical activity recommendations compared to their peers at a healthy weight. As part of a weight management strategy, a tailored exercise program was designed specifically for women facing excessive weight. The purpose of this study was to determine how a special exercise program improves the body composition and the fitness levels in a sample of overweight and obese young women. Methods: A targeted physical exercise program was designed, supervised, and evaluated in a group of 25 overweight and obese young adult women 18 - 24 years (x̅ =20,68±1,6) with a BMI greater than 25 kg/m 2 , before and after 20 weeks of intervention. The intervention yielded measurable improvements in physical fitness and body composition among participants. The ergonomic exercise program ensured safety and effectiveness, and promoted both strength and endurance to enhance overall fitness levels. After computing the t-test for a paired sample, we calculated the Cohen effect size (d) as a measure of the magnitude and practical importance of the observed difference. Conclusions: The results obtained showed statistically significant differences between the two measuring and testing moments. Results indicated a decrease in weight, body fat percentage, and waist circumference, alongside an increase in muscle mass, and progress in all physical fitness tests applied. These findings underscore the importance of developing inclusive, supportive, and contextually tailored exercise interventions for young women who face body weight challenges not only to enhance physical health but also to improved psychological well-being.
