title: Yo-Yo intermittent recovery test versus the Université de Montréal Track Test: relation with a high-intensity intermittent exercise.
abstract: The first purpose of this study was to determine whether the peak velocity (V(Yo-Yo)) achieved during the Yo-Yo intermittent recovery test (Yo-Yo) and the maximal aerobic velocity (MAV) determined from the Université de Montréal Track Test (UMTT) could be used interchangeably. The second purpose was to check that the V(Yo-Yo) is related to the intermittent exercise performance, which consisted of repeated 90 m distance runs in 15s performed until exhaustion, alternated with 15s of passive recovery (15/15). Fourteen amateur soccer players performed, in a random order, the 15/15 and two incremental field-tests: the Yo-Yo and the UMTT. The results of this study showed that MAV was significantly correlated to the V(Yo-Yo) (r=0.79, p<0.01). However, the error was not constant, when the V(Yo-Yo) and the MAV values were higher than 16.3 km h(-1), the MAV values tends to be higher than the V(Yo-Yo), while when the V(Yo-Yo) and the MAV values were lower than 16.3 km h(-1), the MAV values tends to be lower than the V(Yo-Yo). MAV and V(Yo-Yo) were significantly correlated to the time to exhaustion of the 15/15 (r=0.74 and r=0.72, respectively) and show that both tests are similarly related to the high-intensity intermittent exercise performance.
