Understanding Gameplay Acceleration Ability, Using Static Start Assessments. Have We Got It Right?

Despite athletes initiating sprints from dynamic starts during gameplay, sprint performance is traditionally measured from a static position. This article aimed to determine whether static start or “pickup” acceleration are related or relatively independent motor qualities by assessing their relationship and examining how athletes’ rank order changes between static and pickup conditions. Thirty-one male athletes (20.3 ± 5.3 years) completed two 30 m sprints from a static start and two 30 m pickup accelerations following 20 m paced entries at 1.5 and 3.0 m/s, regulated by an LED system. Peak acceleration (amax) was measured via a horizontal linear position encoder (1080 Sprint). The shared variance between amax from the static and pickup starts was R2 =11.6-39.6%, indicating, for the most part, a great amount of unexplained variance. The shared variance between pickup acceleration entry velocities was R2 = 16.8%. Visual analysis of an individualized rank order table confirmed that, for the most part, the fastest static start athletes differed from the fastest pickup athletes. In summary, static and pickup acceleration seem relatively distinct motor abilities, most likely requiring a paradigm shift in strength and conditioning practice in terms of acceleration assessment and development.
