dLéger’s protocol starts at 8.5 km/h and increases 0.5 km/h each minute (Léger et al., 1984, 1988)
eEurofit protocol starts at 8.0 km/h and increases 0.5 km/h each minute, but the second stage increases by 1.0 km/h (Council of Europe Committee for the Development of Sport, 1988)
fQUB’s protocol starts at 8.0 km/h and increases 0.5 km/h each minute (Riddoch, 1990)
dDong-Ho’s protocol starts at 7.5 km/h and increases 0.5 km/h each minute (Dong-Ho et al., 2014).* p < 0.05
cPercentage of variance accounted for by statistical artefacts including sampling error and measurement error of the 20-m shuttle run test
b95% credibility interval
a95% confidence intervalNote. K, number of rs; N, total sample size; r
c, overall weighted mean of r corrected for sampling error only; r
p, overall weighted mean of r corrected for sampling error and measurement error of the 20-m shuttle run test
