Kinetic and kinematic associations between vertical jump performance and 10-m sprint time.
Implementing objective methods to assess physical performance has become an invaluable component of athlete or player development, monitoring, and talent identification in distinct sports. Many sports depend heavily upon muscular strength, muscle power output, and sprint performance, especially at competition level. Therefore, the aim of this study was to examine the relationships between 10-m time and several kinetic and kinematic parameters variables related to a weighted countermovement jump using a linear transducer in a large sample of trained sportsmen. A group of 32 trained sportsmen volunteered to participate in the study (mean ± SD: age 21.4 ± 1.5 years, body mass 67.5 ± 4.8 kg, body height 1.74 ± 0.02 m). The major findings of this study were the significant associations between 10-m sprint time and peak velocity during jumping (r = 0.630; p < 0.01); and also the nonsignificant associations between sprint and of force, mechanical impulse and rate of force development. These results underline the important relationship between 10-m sprint and maximal lower-body strength, as assessed by the force, power, and bar velocity displacement. It is suggested that sprinting time performance would benefit from training regimens aimed to improve these performance qualities.
