- Abstract
Master swimming is experiencing a notable increase in participation rates and performance standards. Various factors influence swimming performance, including biomechanical, physiological, and anthropometric elements. This study explored the intricate relationship between these factors and performance in the 200 m front crawl allout test (T200) among master swimmers. Eighteen male master swimmers (age: 46.3 ± 14.0 years; body mass: 78.0 ± 7.2 kg; height: 1.77 ± 0.06 m) underwent evaluation encompassing anthropometry, body composition, T200 performance, physiological, and biomechanical variables. Physiological and biomechanical data were collected during the T200. Statistical analyses, including correlation and stepwise regression, were conducted at a significance level of a < 0.05. Performance in the T200 (time: 185.8 ± 28.9 s) exhibited significant correlations (p < 0.05) with peak oxygen consumption (VO2peak = 43.9 ± 7.3 ml·kg·min-1) (r = -0.81), maximal heart rate (HRmax = 156.5 ± 13.1) (r = -0.58), stroke length (SL = 1.75 ± 0.21 m) (r = -0.72), stroke rate (SR = 34.8 ± 3.6 cycle·min-1) (r = -0.58), and arm stroke efficiency (ηP = 31.9 ± 3.8%) (r = -0.72). Multicollinearity analysis (p < 0.05) excluded HRmax (which correlated with VO2peak, r = 0.65) and ηP (which correlated with SL, r = 0.99). The resulting regression model included SR, SL, and VO2peak, explaining 48.0%, 48.2%, and 3.7% of T200 performance variance, respectively. Notably, the biomechanical components--SL and SR (kinematics)--are primary determinants of T200 performance, with VO2peak making a relatively small contribution. Consequently, master swimming training should prioritize technical development to enhance efficiency.
