The measurement method of SRT and TT used in this study only
differed in the participant position, sitting for SRT and standing for TT
test. However, it would appear that this difference in participant
positioning adopted in both tests significantly affected the reach
scores. In this sense, a regression analysis and a 95% limits of agree-
ment between SRT and TT test was used to explore if the final reach
score in both test were different and if the same cut-off scores could
be used to detect short hamstring flexibility. The regression analysis
reported a high correlation between SRT and TT test (b ¼ 0.829).
However, the assessing agreement analysis between both tests
showed significant systematic bias (2.84 cm) with a 95% of random
error of -
9.72 cm. Therefore, although the correlation coefficient
between SRT and TT test was high, the 95% limits of agreement
showed considerable discrepancies between the two methods and
the degree of agreement is not acceptable for clinical purposes.
Furthermore, Kappa correlation analysis reported that the TT test was
unable to classify any participant in this sample of recreationally
active young healthy adults as having short hamstring flexibility,
when compared with the PSLR cut-off score. However, SRT was able
to classify participants as having normal or short hamstring flexibility
using the guideline cut-off scores offered by ACSM (1998)
