The purpose of this study was to compare the influence of active recovery (AR) compared to passive recovery (PR), on physiological stress and performance, during a repeated sprint protocol. Additionally, an attempt was made to evaluate the relationship between aerobic capacity and anaerobic performance. Ten male team sport athletes (20.4 (1) y, 183.9 (3.5) cm), 79.3 (7.2) kg) from Cardiff Metropolitan University performed a preliminary VO2max test along with 8 x 6-s sprints separated with 24-s of either AR (cadence of 80 rpm against a resistive load of 1 kg) or PR (stationary) on a Monark cycle ergometer. Maximal oxygen uptake (VO2max) was recorded from the VO2max test. Mean peak power output (PPO), mean average power output (APO), oxygen uptake (VO2) carbon dioxide uptake (VCO2), minute ventilation volume (VE) and heart rate (HR) were recorded for each recovery condition. Compared to AR, PPO and APO was greater (952 (118) vs. 833 (100) W; p<0.05) during the PR. Mean VO2 (3302 (195) vs. 2908 (209) ml.min-1, p<0.05) was significantly higher during the AR, compared to the PR. A significant relationship was not observed with regard to VO2max and the total work done involving PPO and APO (r (df 8) = 0.403, p>0.05; r (df 8) = 0.359, p>0.05). In conclusion, during a repeated sprint cycling protocol, AR was associated with a decline in repeated sprint ability (RSA) and higher muscle deoxygenation. Furthermore, individuals with a greater VO2max do not have a significantly greater RSA (p>0.05). Future research should look into the effects of different time periods involving AR to identify when it proves advantageous, compared to PR.
