(2023). The Relationship between VO2 max and 1200m Shuttle Run Performance in Elite Academy Football Players. International Journal of Sports and Exercise Medicine, 9:261. doi.org/10.23937/2469-5718/15102612469-5718http://hdl.handle.net/10400.15/4716Purpose: To investigate the relationship between VO2 max and performance in the 1200m shuttle run test in elite Premier League academy football players. Methods: Seventeen male professional outfield football players completed a laboratory based incremental treadmill test to establish vVO2 max and a field based 1200m shuttle test to estimate velocity at MAS. During the pre-season period a linear speed phase consisting of twice weekly PS exposures were conducted and each player’s PS reached during this period was established. Body composition was measured using DEXA. Results: Examining the standardized (scaled) coefficients, ASR (7.373) had the largest effect on VO2 max followed by PS (-5.568), MAS (3.604), Body Fat (-0.285) and Lean Mass (-0.185).The results suggest that the model is a significantly better predictor than a model that constantly predicts the mean VO2max value (F = 3.422, p = 0.041). Conclusions: The MAS values obtained from the 1200m shuttle test may be an appropriate assessment to consider when monitoring and individualizing high-intensity performance rather than the generic threshold of 5.5 m/s.engenglish premier leaguefootball, Match performanceindividualizedsoccermatch performancejournal article10.23937/2469-5718/1510261
