A Proposed Method for Evaluating Drop Jump Performance with One Force Platform

The drop jump (DJ) is commonly utilised to assess athletes. criterion two force platform (2FP) method of assessing DJ performance involves adjacent platforms, one for the box and athlete rebound from. Most researchers practitioners only have access (1FP) they rarely account often considerable discrepancy between height (DH). Therefore, this study aimed determine validity evaluating with 1FP. Twenty-six young male sports students performed three DJs, from a 0.30 m 0.40 high box, on platforms. DH, touchdown velocity several variables were calculated using 2FP 1FP methods. Ordinary least-products regression identified no fixed or proportional bias methods any variable. mean DH was 10% lower than 14% box. This highlights importance accounting when conducting assessments. In conclusion, valid alternative could be embedded into automated analysis software utilise.
