Effects of a recovery swim on subsequent running performance.
The effects of a swimming-based recovery session implemented 10 h post high intensity interval running on subsequent run performance the next day was investigated. Nine well trained triathletes performed two high intensity interval running sessions (HIIS) (8x3 min at 85-90% VO(2peak) velocity), followed 10 h later by either a swim recovery session (SRS) (20x100 m at 90% of 1 km time trial speed), or a passive recovery session (PRS). Subsequently, a time to fatigue run (TTF) was completed 24 h post-HIIS. Venous blood samples were taken pre-HIIS and pre-TTF to determine the levels of circulating C-Reactive Protein (CRP). Subjects were also asked to rate their perceived recovery prior to commencing the TTF run. The SRS resulted in a significantly longer (830+/-198 s) TTF as compared to PRS (728+/-183 s) ( P=0.005). There was also a significant percentage change from baseline in the CRP levels 24 h post-HIIS (SRS=-23%, PRS=+/-5%, P=0.007). There were no significant differences in perceived recovery between two conditions ( P=0.40) . The findings of the present study showed that a swimming-based recovery session enhanced following day exercise performance, possibly due to the hydrostatic properties of water and its associated influence on inflammation.
