As a new kind of sport, aquatics have been accepted by general sports enthusiasts. Sports, such as rowing, canoeing, fin swimming, windsurfing, sailing and water polo, have become events of the Olympic Games. Competitions among countries are quite fierce.
Based on the theoretical foundation of fluid mechanics performance, this paper carries out an analysis on mechanical characteristics of aquatic sports. First, basic features of windsurfing are studied in this paper. Performance of windsurfing changes with its parameters, requiring a lot for windsurfers. It can be known from variance analysis that the best performance of NP plate and a relatively small resistance should be the direction of sail-board design. Meanwhile, by building up a mathematical model with fuzzy comprehensive evaluation and correlation analysis, it can be also found that the fluid resistance characteristic is a key factor that influences the performance of windsurfers. Besides, this paper also takes into account external factors, including the influences of regional difference on aquatic events. Different regions with various geographical conditions have different influences on aquatic events.
Key words: aquatics / fluid mechanics / resistance characteristic / regional difference
