![]() ![]() When an individual’s maximum oxygen uptake attained during a laboratory-based test is not feasible, the 20-m shuttle run test seems to be a useful alternative for estimating cardiorespiratory fitness. However, sex and maximum oxygen uptake level do not seem to affect the criterion-related validity values. ![]() The present meta-analysis also showed that the criterion-related validity of Léger’s protocol was statistically higher for adults ( r p = 0.94, 0.87-1.00) than for children ( r p = 0.78, 0.72-0.85). sex, age or body mass) were used ( r p = 0.78-0.95). The overall results showed that the performance score of the 20-m shuttle run test had a moderate-to-high criterion-related validity for estimating maximum oxygen uptake ( r p = 0.66-0.84), being higher when other variables (e.g. From 57 studies that were included in the present meta-analysis, a total of 78 correlation values were analyzed. The Hunter-Schmidt’s psychometric meta-analysis approach was conducted to estimate the population criterion-related validity of the 20-m shuttle run test. ![]() Relevant studies were searched from twelve electronic databases up to December 2014, as well as from several alternative modes of searching. The main purpose of the present meta-analysis was to examine the criterion-related validity of the 20-m shuttle run test for estimating cardiorespiratory fitness. ![]()
