The Effect of wearing clothing on Vo₂ and RPE while Swimming

다국어 초록 (Multilingual Abstract)

For a comparative study between swimming in swimwear and swimming in clothes, oxygen uptake (?o₂) and ratings of perceived exertion (RPE) were measured. The subjects were six male members of a university swimming team. Three swimming strokes - the breaststroke, the front crawl stroke and the elementary backstroke - were applied. With regards to swimming in clothes, swimmers wore T-shirts, sportswear(shirt and pants) over swimwear and running shoes.
In both cases of swimming in swimwear and swimming in clothes, the Vo₂ was increased exponentially with the rise of swimming speed. The ?o₂ of the subjects during the clothed tests did not exceed 1.4 times of that in case of swimming in swimwear at swimming speeds below 0.3㎧. As the swimming speeds increased, the ?o₂ difference in both cases increased. Consequently, the ?o₂ in the clothed tests was equal to 1.5-1.6 times and 1.5-1.8 times of that in the swimwear tests at speeds of 0.5㎧ and 0.7㎧, respectively. AT speeds below 0.6㎧ in swimming in clothes, the breaststroke showed lower Vo₂ than the front crawl stroke, and the elementary backstroke showed higher ?o₂ than the other two swimming strokes. RPE increased linearly with %?o₂max. In addition, any RPE difference among the three swimming strokes was not shown in the swimming in swimwear tests. However, at an exercise intensity above 60%?o₂max, clothed swimmers showed slightly higher RPE in the front crawl stroke compared to the RPE in the two other swimming strokes.
