Therefore, the authors reported that: 1) the test-retest repro-
ducibility measured through method described by Hopkins showed
low within-subject variation and high ICCs for SRT (8.74% typical
error; 0.92 ICC), TT test (9.86% typical error; 0.89 ICC) and PSLR
(5.46% typical error; 0.85 ICC); 2) SRT (b ¼ 0.79) and TT (b ¼ 0.70)
test have a moderate criterion-related validity for estimating
hamstring muscle flexibility measured through the PSLR test; and
3) SRT and TT test need different cut-off values for detection short
hamstring flexibility in active recreationally young adults.
