Relationship between training volume and overuse injuries in female volleyball players

Abstract

Problems and Purpose. Overuse injuries are a result of repetitive stress without sufficient recovery, and female volleyball players are known to have high risk of overuse injuries due to the cumulative impact of these repetitive actions. Overuse injuries can occur due to high training volume, which is important for skill development. This raises the potential for overuse injuries. For this reason, the study was conducted to evaluate the correlation between training volume and the incidence of overuse injuries in female volleyball players. Materials and methods. This study used a cohort research design to evaluate the correlation between training volume and the incidence of overuse injuries in female volleyball players, using a questionnaire to collect demographic data such as age, weight, height, exercise history, and previous injury history and OSTRC to collect data regarding the incidence, severity, and impact of overuse injuries on sport participation and daily activities. The sample consisted of 48 female volleyball players of Yusso Yogyakarta club. Results. Out of 48 respondents, 42 athletes had experienced injuries. Based on the OSTRC measurement there were 22 athletes had no injuries on their knees, while 12 athletes had mild injuries to their knees, 8 athletes had moderate injuries to their knees, 6 people had severe injuries to their knees and none. For lower back injuries, 12 athletes did not suffer any, 30 experienced mild injuries, 6 experienced moderate injuries, 6 experienced severe injuries, and 2 experienced very severe injuries. And for the shoulder area, there were 18 athletes were not injuried, 12 athletes had mild injuries, 14 athletes had moderate injuries, 2 athletes had severe injuries, and 2 others had suffered very severe injuries. The correlation between training volume and the incidence of overuse injuries in female volleyball players was tested using the Spearman test. It was found that the amount of training per week influence knee overuse injury with a significant value of 0.001. The amount of exercise per week also correlates with the incidents of low back overuse injury (significance value of 0.043) and overuse injuries in the shoulder area (significance value of 0.034). Conclusion. This study found that high volume training increases the risk of injury excess in female volleyball players, such as shoulder, knee and wrist injuries. Therefore, It is important to develop a balanced excercise program that includes rest periods and recovery to prevent injury.
