Differences in Mechanical Characteristics of Vertical Jump Between Athletes in Sports Games

Abstract

Vertical jump is one of the most common ways to evaluate the explosive power of lower extremities in athletes. For the development of explosive power, plyometric exercises are mostly used as a form of training. Participants were handball players (N=13), volleyball players (N=13) and basketball players (N=13) from city of Nis. They all competed in the highest state competition. After analyze all data conclusions are that the mechanical characteristics estimated by the accelerometer are statistically not significantly different in the examined athletes' groups except in the jump height and the kinematic characteristics of the vertical jump obtained by the video analysis statistically do not differ significantly, except in the variations of the angular velocity in the hip joint in the ankle.

Maximal Muscular Strength as a Predictor of Optimum Drop Height

“…The importance of the knee extensor muscles in the high intensity drop jump efforts was shown in previous reports (Hobara et al, 2009;Horita, Komi, Nicol, & Kyröläinen, 2002). Kinematic characteristics of the knee joint during a maximal vertical jump do not differ significantly between different athletes, whereas significant variations are reported in angular velocity of the hip and ankle (Đokić, Radenković, & Stanković, 2018). High angular velocity and full muscle activation during an eccentric contraction, lead to an increase in overall work rate during CMJ (Stojanović, Ĉoh, & Bratić, 2016).…”
