Modified Warm-Up Model: A Development Study For Football Players Post Ankle Injury

Injuries are common among football players, and the risk factors have been well documented in the literature. This is because football is a high-intensity sport that is performed repetitively, such as jumping, running, and touching opponents when tired. This study aimed to develop a warm-up model for football players after an ankle injury. This type of research was R&D using the Borg & Gall method. The trial design included two stages, namely feasibility testing and effectiveness testing. In conducting the feasibility test, 7 football players were selected using purposive sampling, the feasibility test was carried out, then revised and continued to the effectiveness test stage. The effectiveness test was the final stage trial conducted on 15 football players. Based on these results, the development of a warm-up model was declared feasible to be used as a warm-up activity for athletes after an ankle injury. The post-injury ankle warm-up model was effective in reducing pain and improving functional ability, with a percentage effectiveness of pain reduction of 70.57% and a percentage increase in function of 23.24%. Based on the results of the data obtained from the large-scale test and the effectiveness test, it can be concluded that the warm-up model for football players after ankle injury can reduce pain levels and improve functional abilities so that it can be accepted as a warm-up model that can be used to treat ankle injuries. It is also evident that the effectiveness of the pain scale and functional ability both obtained a significance value smaller than 0.05, namely 0.001. Keywords: Injury Ankle, Sports, Football.
