Study population: The study population consists of futsal players aged 18-45. This includes two groups: (1) players without ACL injuries who serve as a comparison group, and (2) players who have sustained ACL injuries and are undergoing or have undergone ACL reconstruction surgery. The study aims to compare Anthrogenic Muscle Inhibition (AMI) and muscle function between these two groups.

Brief summary: The Anterior Cruciate Ligament (ACL) is vital for knee stability, and ACL injuries in futsal can lead to long-term issues. Reconstruction surgery may be affected by Anthrogenic Muscle Inhibition (AMI), especially in the vastus medialis muscle. This study aims to compare AMI in futsal players with ACL injuries to those without injuries, focusing on measurement techniques, sports performance, muscle strength, and recovery time. The research involves evaluating 54 players (27 injured and 27 non-injured) at various stages of the season using strength tests and imaging.

Detailed description: Introduction: The Anterior Cruciate Ligament (ACL) is crucial for knee stability and represents a major challenge in sports such as futsal. ACL injuries can carry a risk of long-term complications. While reconstruction surgery is a common method for recovery, it can be affected by Anthrogenic Muscle Inhibition (AMI), especially in the vastus medialis. Research on AMI in futsal players will be fundamental to improve rehabilitation, functionality, and reduce the risk of relapse.

Objectives: To analyze the changes in the Anthrogenic Muscular Inhibition of the vastus medialis in futsal players with Anterior Cruciate Ligament Injury compared to non-injured players. The specific objectives include evaluating measurement techniques, assessing the impact on sport quality, assessing muscle strength, and examining recovery time.

Methodology: The present study uses an observational cohort design to evaluate AMI in indoor soccer players at different stages of the soccer season, compared to players who suffer ACL injuries during competition. The sample size is 54 subjects, with 27 in each group. Accounting for a 15% loss, the final sample will be 64 subjects (32 in each group). Players will be evaluated for isometric strength by electromyography, strength in extensors, single leg vertical jump test, and ultrasound evaluation. These measurements will be taken for all players in the pre-season, after 4 months, and at the end of the season. For ACL injuries, evaluations will be conducted pre-operation, 4 months post-operation, and at the end of the soccer year.

Key words: Anthrogenic Muscle Inhibition, soccer, Anterior Cruciate Ligament, Rehabilitation.
