The 95% prediction intervals of SRT and TT test average scores
for estimating the range of possible PSLR scores were calculated
following the procedure reported by Bland (2009). The magnitudes
of the 95% prediction intervals were wide for both tests
(SRT ¼ 63.13e111.95; TT test ¼ 67.34e112.06). These data
support the idea that the criterion-related validity of SRT and TT
test for measuring hamstring flexibility is moderate
