A 20 × 20 m repeated sprint field test replicates the demands of wheelchair rugby

Objectives: To assess the physiological responses to, and the agreement between, a 20 × 20 m repeated sprint field test and wheelchair rugby game play, as well as the reliability of the test. Design: Cross-sectional and longitudinal. Methods: Heart rate (HR), blood lactate ([La-]B), and ratings of perceived exertion (RPE) were collected in nineteen elite wheelchair rugby athletes before, during, and after a 20 × 20 m repeated sprint field test and game play. Times to complete 5, 10, and 20 m during the field test were also collected. Results: Peak HR and peak [La-]B were positively correlated during the field test (r = 0.470, p = 0.043), as were peak HR and peak speed (r = 0.493, p = 0.031), and peak [La-]B and peak speed (r = 0.559, p = 0.013). During game play, peak [La-]B was correlated with peak RPE (rho = 0.703, p = 0.001). Intra-class correlations (ICCs) between the field test and game play were significant for peak HR (ICC = 0.922, p < 0.001) and peak [La-]B (ICC = 0.845, p < 0.001). Bland-Altman analysis revealed good agreement between HR and [La-]B obtained during the field test and game play and excellent between-day reliability of the 20 × 20 m sprint test. Conclusions: The physiological demands of a 20 × 20 m repeated sprint field test are similar to those of elite wheelchair rugby game play and the test is highly reliable. This simple to implement field test may be useful as a component of team selection and in assessing the effectiveness of training interventions or monitoring athletes across training phases.
