Repeatable techniques for assessing changes in passive swimming resistance
Repeatable techniques for assessing changes in passive swimming resistance
Two different methods of measuring the passive resistance of swimmers are used to compare system accuracy and repeatability. Method I uses a submerged glide tow, and Method II, a novel, simpler approach, is based on measuring deceleration during a submerged push-off glide. The comparison of each method is made for specific changes in passive resistance. A set of three male and three female swimmers compare the use of drag shorts to make swimmer-specific increases in drag. In a second study, the effect of hair removal is quantified on a single male swimmer (Method I 9.7% reduction and Method II 9.4% reduction). For five repeat tests, a 1.8% difference in resistance can be resolved with 95% and 70% confidence levels for the passive tow and push-off glide experiments, respectively

Abstract
Two different methods of measuring the passive resistance of swimmers are used to compare system accuracy and repeatability. Method I uses a submerged glide tow, and Method II, a novel, simpler approach, is based on measuring deceleration during a submerged push-off glide. The comparison of each method is made for specific changes in passive resistance. A set of three male and three female swimmers compare the use of drag shorts to make swimmer-specific increases in drag. In a second study, the effect of hair removal is quantified on a single male swimmer (Method I 9.7% reduction and Method II 9.4% reduction). For five repeat tests, a 1.8% difference in resistance can be resolved with 95% and 70% confidence levels for the passive tow and push-off glide experiments, respectively
