When and for whom are relative age effects important? evidence from a simple test of cardiorespiratory fitness

“…The shuttle run is a widely used test of cardiorespiratory fitness (Leger and Lambert, ; Léger et al, ) that involves running back and forth between two lines set 20 m apart in synchrony to a beep, with the time between beeps becoming progressively shorter until the participant cannot continue. The number of stages completed is a measure of cardiorespiratory fitness that can be combined with age and sex to estimate maximum volume of oxygen consumed (Léger et al, 1988; Melo et al, ; McCammon et al, ; Van Mechelen et al, ). Shuttle runs were conducted in school gymnasia.…”
