Activation of the Gluteus Maximus During Performance of the Back Squat, Split Squat, and Barbell Hip Thrust and the Relationship With Maximal Sprinting

Williams, MJ, Gibson, N, Sorbie, GG, Ugbolue, UC, Brouner, J, and Easton, C. Activation of the gluteus maximus during performance back squat, split barbell hip thrust relationship with maximal sprinting. J Strength Cond Res 35(1): 16–24, 2021—The purpose this research was to compare muscle activation ground reaction force between thrust, squat determine these outcomes vertical horizontal forces Twelve, male, team sport athletes (age, 25.0 ± 4.0 years; stature, 184.1 6.0 cm; body mass, 82.2 7.9 kg) performed separate movements 3 strength exercises at a load equivalent their individual repetition maximum. The measured using plates electromyography (EMG) activity upper lower recorded in each leg expressed as percentage maximum voluntary isometric contraction (MVIC). Subjects then completed single sprint on nonmotorized treadmill for assessment velocity forces. Although lower, peak EMG higher than (p = 0.024; 95% confidence interval [CI] 4–56% MVIC) 0.016; CI 6–58% MVIC). Peak correlated both anterior-posterior (r 0.72) 0.69) but no other variables. increased running speed suggests that movement may be optimal training group comparison squat.
