INTRODUCTION: Aerobic and anaerobic capacity are considered key performance indicators in team ball sports. However, diagnostics focus on treadmill testing or linear sprints, not considering multidirectional change of direction and reactive agility. This study evaluated the validity of a novel multidirectional reactive agility test (RA test) to determine aerobic and anaerobic capacity in high-level female handball athletes.
METHODS: Fourteen first-team female handball players performed four all-out 150 m multidirectional RA runs on the SKILLCOURT. Maximum oxygen uptake (VO2max) was determined using a mobile gas analyzer and compared to an incremental ramp test on the treadmill. For anaerobic performance, peak power output (PPOmax), average power output (PPOav), fatigue index (FI) and anaerobic capacity (AC) were calculated based on running time in the RA test and correlated to the repeated anaerobic sprint test (RAST).
RESULTS: Bland-Altman analyses revealed a mean difference in VO2max between the RA test and the treadmill test of 0.07 mL × kg-1 × min-1 (0.1%) with upper and lower limits of agreement (LoA) at 4.03 (8%) and -3.88 (8%) mL × kg-1 × min-1, respectively. Measured VO2max values from the RA test and treadmill were strongly related (r = 0.91) and not significantly different (p = 0.90, d = 0.04). No significant correlations were found for any of the anaerobic variables (p ≥ 0.40).
DISCUSSION: The results support the suitability of a RA test protocol for directly measuring and estimating aerobic capacity (VO2max). This was not confirmed for anaerobic parameters. The RA test may provide a promising sport-specific alternative to existing lab and field protocols for determining VO2max in team ball sports.
