Reduced Fatigue in Passive Versus Active Recovery: An Examination of Repeated-Change-of-Direction Sprints in Basketball Players.

Abstract

To investigate the physiological and performance effects of active and passive recovery between repeated-change-of-direction sprints. Eight semiprofessional basketball players (age: 19.9 [1.5]y; stature: 183.0 [9.6]cm; body mass: 77.7 [16.9]kg; body fat: 11.8% [6.3%]; and peak oxygen consumption: 46.1 [7.6]mL·kg-1·min-1) completed 12 × 20-m repeated-change-of-direction sprints (Agility 5-0-5 tests) interspersed with 20 seconds of active (50% maximal aerobic speed) or passive recovery in a randomized crossover design. Physiological and perceptual measures included heart rate, oxygen consumption, blood lactate concentration, and rating of perceived exertion. Change-of-direction speed was measured during each sprint using the change-of-direction deficit (CODD), with summed CODD time and CODD decrement calculated as performance measures. Average heart rate (7.3 [6.4] beats·min-1; P = .010; effect size (ES) = 1.09; very likely) and oxygen consumption (4.4 [5.0]mL·kg-1·min-1; P = .12; ES = 0.77; unclear) were moderately greater with active recovery compared with passive recovery across sprints. Summed CODD time (0.87 [1.01]s; P = .07; ES = 0.76, moderate; likely) and CODD decrement (8.1% [3.7%]; P < .01; ES = 1.94, large; almost certainly) were higher with active compared with passive recovery. Trivial-small differences were evident for rating of perceived exertion (P = .516; ES = 0.19; unclear) and posttest blood lactate concentration (P = .29; ES = 0.40; unclear) between recovery modes. Passive recovery between repeated-change-of-direction sprints may reduce the physiological stress and fatigue encountered compared with active recovery in basketball players.
