Does active recovery improve peak power, fatigue rate, and total work in athletes during short-term, high intensity power activities compared to passive recovery?
Active recovery between short, high-intensity exercise bouts significantly improves peak power and total work output compared to passive rest.
The advantage of active over passive recovery from long and intermediate duration exercise is well documented. Success has been attributed to metabolite washout and/or lactate (La) utilization by the active musculature. This study was designed to determine whether active recovery was superior to passive rest during short duration, high intensity performance. On 4 separate days, six athletes performed a set of eight 6-s power tests separated by 30-s recovery intervals under two recovery conditions. Recovery conditions involved either sitting passively on the bike (P) or actively pedaling (A) at 60 rpm using 1 kg resistance. A MANOVA on peak power (PP), fatigue rate (F), and total work (TW) showed a significant difference due to recovery condition, F(3, 169); p < .0001. Separate ANOVAs revealed that PP (A = 1192.85 watts, P = 1134.57 watts; p < .0001) and TW (A = 6.59 kJ, P = 6.23 kJ; p < .0001) differed significantly between conditions. No difference was found for F (A = 80.12 watts.sec-1, P = 79.80 watts.sec-1). Results indicate that active recovery provides superior performance to passive rest in repeated short-term, high intensity power activities.
