Abstract

Purpose: Active recovery (AR) and cold-water immersion (CWI) are currently the gold standards for intermittent exercise recovery and recovery across days, respectively. The localized cooling of cold water immersion inhibits its beneficial effects during intermittent recovery by decreasing power. Cold water immersion wearing a lower body neoprene suit (CWIN), however, reduces localized cooling and may potentiate beneficial effects, perhaps making CWI useful for intermittent recovery. Therefore, this project compared the effects of AR and CWIN on repeated sprint cycling performance. Methods: Ten physically active individuals volunteered to participate in the study; their mean and SD for age, height and weight were: 25 (5.1 y), 173 (8.6 cm), and 76 (11.6 kg). Subjects performed the testing protocol on two occasions [(treatment (CWIN) and control (AR)] separated by seven days in a randomized crossover design. Each lab visit, the subjects completed three 30 s Wingate sprints with 7.5% of their bodyweight as resistance interspersed with four min of light cycling (60 rpm 1 kg). The first Wingate sprint test was baseline and the following two were used to cause fatigue. Subjects then completed a 5 min passive recovery, 12 min recovery modality (CWIN or AR), and another 5 min passive recovery. After the 22 min recovery period, subjects performed a fourth 30 s Wingate sprint. Across sprints one and four power output, blood lactate, temperature, rating of perceived recovery, and heart rate were compared using repeated measures ANOVAs. Results: There was no significant difference between CWIN and AR for power (peak and mean), lactate, temperature, and rating of perceived recovery. Heart rate was significantly lower with CWIN (F(1,9) = 45.424, p < 0.001, ηp2 = .835). Peak power was significantly lower from Wingate 1 to Wingate 4 with AR (-6.20%, p < iv 0.05). Conclusion: The findings show that neither CWIN nor AR is a superior recovery modality for physically active individuals, however CWIN alleviated traditional CWI intermittent power deficits.
