Abstract
This study compared vertical force and time at time reference points between backstroke start performed with and without wedge, and identified the relationships with 5 m start time. Ten swimmers (age 21.1 ± 5.36 years, stature 1.78 ± 0.04 m, body mass 72.82 ± 10.05 kg and mean 100 m backstroke performance of 59.67 ± 2.89 s) completed eight backstroke starts (four with and four without wedge) using the highest horizontal handgrip. An instrumented starting block recorded vertical force and time at the following points: (i) start signal; (ii) peak before hands-off; (iii) minimum at hands-off; and (iv) peak before take-off. Forces at instants after the start signal were greater when using the wedge and no relationships were observed between force, time at reference points and 5 m time. The wedge use can benefit vertical forces generation but not directly 5 m time.
