Official title
Optimizing Hamstring Rehabilitation With Amino Acids: A Randomized Controlled Study for Seamless Return to Sports in Football Athletes
Overview
Hamstring injuries are among the most prevalent and troublesome injuries in athletes, particularly those engaged in sports that require high-speed movements such as sprinting, kicking, and rapid changes in direction. The hamstring muscles, which include the biceps femoris, semitendinosus, and semimembranosus, are essential for powerful lower limb actions, and thus, any injury to these muscles can significantly impact an athlete's performance and recovery. These injuries often occur during eccentric muscle contractions, such as when the muscles lengthen rapidly under tension, as seen in running and sprinting. According to epidemiological studies, hamstring strains account for a substantial portion of sports-related injuries, with hamstring strains being the most commonly reported injury in disciplines such as football, soccer, rugby, and athletics. In professional football, for instance, hamstring injuries account for approximately 12% of all injuries and represent the most frequent muscle strain, underlining their significance in the context of athletic performance.
Interventions
- Dietary supplement Branched-Chain Amino Acid Supplement
Oral BCAA blend (leucine, isoleucine, valine), 10 g/day divided into two doses, pre- and post-training, for 6 weeks. - Behavioral Therapeutic Exercise Program
6-week structured program including isometric, eccentric, plyometric, and sprint-specific exercises.
Primary outcome measures
- Change in Hamstring Muscle Strength [Time frame: Baseline, Mid-Rehabilitation (Week 3), Post-Rehabilitation (Week 6)]
Secondary outcome measures (1)
- MRI Findings [Time frame: Baseline and Post-Rehabilitation (Week 6)]
