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
