| Outline of Final Research Achievements |
The purpose of this study was to assess the active recovery effects of on training load during interval swimming. Well-trained swimmers performed a graded test and 6 rounds for 60-s, with 30-s of either active or passive recovery. The tethered loads of swimming and active recovery were set at 100%VO2max and 50%VO2max, respectively. Oxyhemoglobin (O2Hb) and deoxyhemoglobin (HHb) levels at the left vastus lateralis muscle were determined using a NIRS device. Mean value for oxygen uptake during the rest period was higher with active recovery condition than passive recovery condition. O2Hb variations during rest period for active recovery were significantly lower than for passive recovery. HHb variations during rest period for active recovery were significantly higher than for passive recovery. Active recovery during interval swimming was associated with higher oxygen uptake response and lower muscular reoxygenation.
