PDF Influence of Competitive Swim-suits on Swim Performance

【Supercategory:7. DESCENTE SPORTS SCIENCE Subcategory:7.23 Vol.23

 The purpose of this study was to determine the effect of swim-suit on water flow around human body, passive drag and swimming performance as compared new type suits which fully covered legs and classic type suit. The subjects were male college swimmers who carried out at the swim flume during all experiments. The results were as follows. There were approximately 4% decrement of passive drag with wearing new type suit at 1.50 m/s, 1.80 m/s and 2.00 m/s respectively compared with wearing classic type suit but not significant.
The exhaustion time swum at 85% best record of 100m freestyle was significantly longer in new type suit than classic type suit.
These results suggested that the new type suit might decrease the drag, make water flow laminar around human body and improve swimming performance at high intensity.
