Effect of the Fast-Skin swim suit on Iranian elite female swimmer's performance

The purpose of this investigation was to consider the Fast-Skin swimsuit's effect on the elite female swimmers’ performance. So, twelve elite swimmers swam 50 and 200 m and 400 m trials with and without Fast-Skin at approximately 80- 100% of maximal effort in four swimming styles. In 400 m freestyle swimming, traditional swimsuit compared with shoulder-to-ankle (SA) and shoulder-to-knee (SK) of Fast-Skin (to control intensity, blood lactate and heart-rate was measured). Also the propelling force of subjects was measured with indirect way. Results showed, there was significant reduction in records of 50 m front crawl, backstroke and butterfly, while no significant differences observed in breaststroke. In 200 m for four swimming styles, reduction records were significant. Also, different significant effect seen using traditional swimsuit in comparison with SA and SK. Fast-Skin provide significant increased in propelling force of front crawl, backstroke and butterfly, but no significant propelling force observed in breaststroke. Using SA especially in fast front crawl and semi-endurance butterfly and SK in endurance freestyle are recommended.
