For this purpose relevant studies were searched from five electronic databases dated up through September 2012. Primary outcomes of criterion-related validity were Pearson´s zero-order correlation coefficients (<em>r</em>) between the toe-touch test and hamstring extensibility criterion measure. Then, from the included studies, the Hunter-Schmidt´s psychometric meta-analysis approach was conducted to estimate population criterion-related validity of the toe-touch test. Firstly, the corrected correlation mean (<em>r</em><sub>p</sub>), unaffected by sampling error and measurement error, was calculated. Subsequently, the three potential moderator variables (sex of participants, age of participants, and level of hamstring extensibility) were examined by a partially hierarchical analysis. Of the six studies included in the present meta-analysis, 12 correlations values were retrieved. The overall results showed that the toe-touch test have a moderate mean criterion-related validity for estimating hamstring extensibility (<em>r</em><sub>p </sub>= 0.66, 0.54-0.79). Generally, females, children and individuals with high levels of hamstring extensibility seem to have greater mean values of criterion-related validity for estimating hamstring extensibility. However, due to the low number of <em>r </em>values found, the fact that almost all the 95% CIs of mean correlation coefficients were overlapped, and that criterion-related validity of the toe-touch test within each category was still heterogeneous, we should be cautious with the results of the present meta-analysis. When the use of the angular tests is limited, the toe-touch test seems to be a useful alternative to estimate hamstring extensibility.</p>}, number={1}, journal={Journal of Human Sport and Exercise}, author={Mayorga-Vega, Daniel and Viciana, Jesús and Cocca, Armando and Merino-Marban, Rafael}, year={2014}, month={Jun.}, pages={188–200} }
