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.

Interventions

Type	Name	Description
OTHER	Anthrogenic Muscle Inhibition (AMI) Assessment Protocol	This study involves evaluating Anthrogenic Muscle Inhibition (AMI) of the vastus medialis muscle in futsal players. The intervention includes assessments of muscle strength, AMI using electromyography, ultrasound evaluation, and single-leg vertical jump tests. These evaluations are conducted at different stages throughout the season: pre-season, 4 months in, and at the end of the season. The goal is to compare AMI levels and muscle function between players with ACL injuries and those without.
