Author's abstract

The primary objective of this investigation was to determine the thermal and metabolic effects of wearing a rubberized wet suit (WS) while swimming for 30 min in 20.1, 22.7, and 25.6øC water. Metabolic and body temperature measurements were recorded in each water temperature with subjects wearing either a WS or a competitive swimming suit (SS). Immediately after each swim the subjects cycled for 15 min on a stationary cycle ergometer. Energy expenditure (VO2), heart rate, post-swim blood lactate, work completed on the cycle ergometer, and rating of perceived exertion (RPE) were similar in all trials. Mean (+/-SE) core temperature (Tc) during swimming in the SS trials increased 0.56 (+/-0.33), 0.48 (+/-0.20), and 1.22 (+/-0.24)øC, whereas in the WS trial Tc rose 0.62 (+/-0.22), 1.02 (+/-0.15), and 0.89 (+/-0.13)øC in the 20.1, 22.7, and 25.6øC treatments, respectively. Following swimming many of the subjects experienced a decrease in Tc, but it was significantly elevated above preimmersion by the end of cycling in all trials except the SS 20.1øC trial. Mean trunk temperatures (Ttr) during swimming in the WS trials were 4.32+/-0.16 (20.1øC), 3.90+/-0.25 (22.7øC), and 3.21+/-0.20 (25.6øC)øC warmer than in the SS. Ttr rose after the subjects exited the water, but remained significantly below baseline throughout cycling in all trials. These findings suggest that wearing a rubberized wet suit during swimming in water ranging from 20.1 to 25.6øC did not subject the swimmers to any greater risk of hyperthermia than when they wore a conventional competitive swimming suit. However, in some individuals the WS prevented a fall in core temperature during swimming. Verf.-Referat
