Outline of Final Research Achievements

Present study aimed to examine the effects of voluntary B and H during gliding and swimming on performance. Subjects performed gliding using a towing machine with a constant force and 20m front crawl swimming with their maximal effort in B, H and normal condition (N). As this results, no significant differences were observed in V during gliding in both of groups. Additionally, there were not significant differences in V and IAP among conditions in competitive swimmers during swimming. In recreational swimmers, however, N was significant higher than H in V, and N and H was significantly lower than B in IAP. Taken together, these results suggest that voluntary contraction of trunk muscles would be no affect on gliding and swimming performance regardless in swimming performance levels.
