IMTP: isometric mid-thigh pull test; SJ: squat jump test; CMJ: countermovement jump test; RSI: reactive strength index; a: significantly different
from SFG (p < 0.05); b: significantly different from LFG (p < 0.05); c: significantly different from control (p < 0.05);*: significant within-group difference (post-pre) for a p < 0.05.
