Thirty-three young men were randomly assigned into three experimental groups (VL10%, VL30%, and VL45%; n = 11 each) that performed a velocity-based RT program for 8 weeks using only the full squat exercise (SQ). Training load (55-70% 1RM), frequency (2 sessions/week), number of sets (3), and inter-set recovery (4 min) were identical for all groups. Running sprint (20 m), countermovement jump (CMJ), 1RM, muscle endurance, and EMG during SQ were assessed pre- and post-training. All groups showed significant (VL10%: 6.4-58.6%; VL30%: 4.5-66.2%; VL45%: 1.8-52.1%; p enathletic performanceelectromyographymuscle adaptationsmuscle strengthneuromuscular fatiguevelocity-based resistance trainingAdultAthletic PerformanceExercise TestHumansLongitudinal StudiesMaleMuscle StrengthResistance TrainingYoung Adultresearch article3382967910.1111/sms.139671600-0838
