Abstract |
The aim of this study was to investigate the effect of self-paced active recovery (AR) and passive recovery (PR) on blood lactate removal following a 200 m freestyle swimming trial. Fourteen young swimmers (with a training frequency of 6-8 sessions per week) performed two maximal 200 m freestyle trials followed by 15 minutes of different recovery methods, on separate days. Recovery was performed with 15 minutes of passive rest or 5 minutes of passive rest and 10 minutes of self-paced AR. Performance variables (trial velocity and time), recovery variables (distance covered and AR velocity), and physiological variables (blood lactate production, blood lactate removal, and removal velocity) were assessed and compared. There was no difference between trial times in both conditions (PR: 125.86±7.92 s; AR: 125.71±8.21 s; p=0.752). AR velocity was 69.10±3.02% of 200 m freestyle trial velocity in AR. Blood lactate production was not different between conditions (PR: 8.82±2.47 mmol L(-1); AR: 7.85±2.05 mmol L(-1); p=0.069). However, blood lactate removal was higher in AR (PR: 1.76±1.70 mmol L(-1); AR: 4.30±1.74 mmol L(-1); p<0.001). The velocity of blood lactate removal was significantly higher in AR (PR: 0.18±0.17 mmol L(-1) min(-1); AR: 0.43±0.17 mmol L(-1) min(-1); p<0.001). Self-paced AR shows a higher velocity of blood lactate removal than PR. These data suggest that athletes may be able to choose the best recovery intensity themselves. |
