Purpose: To compare the standard Yo-Yo intermittent recovery (IR) test and an agility Yo-Yo IR test with a higher number of change-of-direction movements to cardiorespiratory match performance. Methods: The study included 11 professional male handball players (age 24.5 [4.6] y) of a German second-league team. The performance parameters of the players of the seasons 2016-17 to 2018-19 were analyzed. The Yo-Yo IR test was compared to a Yo-Yo IR test with multiple multidirectional changes of direction in response to visual stimuli, which was conducted on a SpeedCourt (Yo-Yo SC IR). Peak oxygen uptake (VO(2)peak) and maximum heart rate (HRmax) were measured. Between-methods differences of individual athletes were quantified with Bland-Altman plots. Results: HRmax was not statistically different during the Yo-Yo SC IR test compared to the Yo-Yo IR test (181 [10] vs 188 [8] beats<middle dot>min(-1); P = .16). Agreement between the 2 tests was moderate for HRmax and good for heart rates >180 beats<middle dot>min(-1). Mean average VO(2)peak was 51.7 (3.9) and 50.9 (2.8) mL<middle dot>min(-1)<middle dot>kg(-1) for the Yo-Yo SC IR test and the Yo-Yo IR test (P = .693), respectively. Conclusions: A Yo-Yo test with multidirectional changes of direction in response to visual stimuli yielded good agreement with the frequently used linear running tests and can be used to assess players' VO(2)peak. The HRmax achieved during this test should be used with caution.
