Validation and Reliability of the Wheeler Jump Sensor for the Execution of the Countermovement Jump

Our founder Carlos Wheeler and some of his peers wrote this insightful article. It will help you understand why the Wheeler Jump is a reliable tool that provides accurate information regarding physical performance.

Many coaches have used the vertical jump as an indicator of neuromuscular performance. A total of 119 high-performance athletes from different sports disciplines were selected in a non-probabilistic and convenient manner. Jump performance was evaluated through the CMJ in a training session. We compared Chronojump Boscosystem contact platform, the OptoGait photoelectric system, and the My Jump 2 mobile application as measurement tools results with the values obtained with our sensor. The research established Statistically significant validity and reliability.

Historically, many coaches have used the vertical jump as an indicator of neuromuscular performance. (Montalvo et al., 2021). During the decade of the sixties, Professor Rodolfo Margaria was the first person to talk about the relevance of the so-called StretchShortening Cycle (SSC). He stated that a concentric contraction preceded by an eccentric one could generate higher levels of strength than an isolated concentric contraction (GarcíaLópez et al., 2003).

Most sports movements and actions comply with this SSC, thus facilitating concentric contractions or propulsive phases. For that reason, The Countermovement Jump has been the most popular indicator of neuromuscular efficiency in athletes. This jump has been described in the literature as a determinant of the elastic explosive manifestation of strength.
