Abstract
Introduction. The purpose of this study is to investigate the effects of fatigue on the Center-of-pressure parameters and the time to stability (TTS) in basketball players of 20 to 30 years.
Method. The current study was considered as semi-experimental research with a pre-test and post-test design. The current research community consisted of a semi-professional indoor and street basketball player of Rasht, who were between 20 and 30 years old and had at least three years of experience in the field of basketball. The subjects performed the task of jumping and landing from a 30 cm high obstacle and landed with one foot in the center of the force plate. The Kistler force plate was used to evaluate postural control and the time to stability (TTS). Dependent t-test, Mann–Whitney U test and Wilcoxon tests were used to compare the mean of research variables.
Results. The results show that the fatigue protocol has a significant increasing effect on postural control variables (p=0.03), TTS in medio-lateral (p=0.02), anterior-posterior (p=0.01) and vertical (p=0.03) directions among the basketball players.
Conclusion. The results showed that the fatigue protocol had a significant effect on postural control and the TTS in basketball players, and it caused poor postural control and increased time to stability after landing in basketball players. Poor postural control and increased TTS are indicators that increase the probability of injury; Therefore, in order to avoid the possible injury caused by poor postural control and increased TTS, the occurrence of fatigue should be avoided.
