The impact of a rehabilitation program to develop neural conduction speed (EMG) and thrust strength of hip joint muscles to reduce injuries in freestyle swimmers

The study aims to:Investigate the impact of a rehabilitation program on developing neural conduction speed using EMG and the thrust strength of hip joint muscles to reduce injuries in freestyle swimmers. The researchers used the experimental method for its suitability to the nature of the research, employing an experimental design with two groups: an experimental group and a control group. The sample was intentionally selected, consisting of 12 freestyle swimmers divided into the experimental group (6 players) and the control group (6 players) aged between 17 and 19 years. Homogeneity and equivalence were ensured among all variables. The rehabilitation program was applied for 12 weeks, with 3 weekly sessions, combining proprioceptive neuromuscular facilitation (PNF) exercises and plyometric exercises with body weight and additional weights. Data were collected through the used measurements and statistically processed. The research procedures included pre- and post-tests over 3 months of the program's application. The key findings revealed that the proposed rehabilitation program positively affected neural conduction speed variables, thrust strength, electrical activity, and physical variables. Additionally, it helped reduce the discrepancy in muscle strength balance between the working and opposing muscles, thereby minimizing injuries.
