Introduction: Due to the increased time to stabilization potentially leads to injury. Given the obliquity damages resulted from fatigue, examining its relationship with time can provide useful insights. To study the effects of and exhaustive exercise on time to stabilization, changing the center of pressure-mass and ground reaction force in the jump-landing in Iran's Premier League Handball players.
Methodology: Ten male handball player attending Iran’s league (2015), participated in this study. Before starting the test, they were instructed jump-landing method and were required to stand around 70cm away from a center of force plate. They were also required to jump over a hurdle of 30 cm using both feet and landing on force plate so that to keep their stability in 20 seconds. Muscle fatigue of hip, knee and ankle joints was performed using isokinetic dynamometer. Then the participants asked to jump-landing on the force plate immediately and after 10 minutes of the fatigue protocols. Time to stabilization in mediolateral anterior-posterior direction were measured.
Results: The statistical results showed after exhausting ankle joint, in anterior-posterior direction time to stabilization significant findings. However, when comparing between the time to stabilization (Ankle, knee and hip) produced was not significant findings.
Discussion: In general, we can conclude that the lower limb muscle fatigue and exhaustion can increase the time to stabilization and the force on foot (due to muscle fatigue and reduced activity of regulators) and reduces their balance sports performances and may cause long-term damage to the structure. Therefore, the design and the inclusion of special endurance programs play an important role because the muscles that can handle long contractions are more resistant to fatigue and have ability to support their limbs in a long time. It can maintain long-term athletic performance activities.
