If the swimmer action is covered at constant average speed is possible to investigate the balance between thrust force (Ft) and resistant drag force (Fd) (Toussaint, 1992). The towing passive drag in a hydrodynamic stable position has been showed a remarkable consistency method to measure the swimmer’s drag. Fully tethered swimming is a useful tool to asses the Ft and it has a high correlation with the swimming sprint performances (v). In relationship to 25m speed (v25), we compared the estimation of the swimming power propulsion obtained with the power thrust experiments (15s all-out of front crawl tethered) and the power drag method estimated from the passive towing measurement.

Abstract
If the swimmer action is covered at constant average speed is possible to investigate the balance between thrust force (Ft) and resistant drag force (Fd) (Toussaint, 1992). The towing passive drag in a hydrodynamic stable position has been showed a remarkable consistency method to measure the swimmer’s drag. Fully tethered swimming is a useful tool to asses the Ft and it has a high correlation with the swimming sprint performances (v). In relationship to 25m speed (v25), we compared the estimation of the swimming power propulsion obtained with the power thrust experiments (15s all-out of front crawl tethered) and the power drag method estimated from the passive towing measurement.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
