Estimating Maximal Aerobic Speed in Academy Soccer Players: A Comparison Between Time Trial Methods and the 30-15 Intermittent Fitness Test.

ABSTRACT: Aerobic fitness is crucial to team sport performance and can be practically estimated through field-based assessments of maximal aerobic speed (MAS) in soccer players. However, method comparisons are underexplored. This study compared MAS estimation via a 6-min distance trial (6minDT), 1800-m time trial (1800mTT) and 30-15 intermittent fitness test (30-15IFT) and qualitative preferences in academy soccer players. Twenty-six male players (age: 17.2 ± 0.6 years; stature: 178.4 ± 5.1 cm; body mass: 71.8 ± 7.7 kg) completed a 30-15IFT, 6minDT and 1800mTT in a counterbalanced order. Total distance was measured via 10 Hz global positioning system units, with MAS defined as 87% of 30-15IFT finishing speed (vIFT) and distance divided by time to completion for the 6minDT and 1800mTT.
