Evaluation of Vastus Medialis Muscle Inhibition in Indoor Soccer Players With and Without ACL Injury

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.

About this study

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.

Treatment and study plan

Anthrogenic Muscle Inhibition (AMI) Assessment Protocol

Other

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.

Other names: Vastus Medialis AMI Assessment, Isometric Strength Evaluation Protocol

Primary outcomes

  1. Anthrogenic Muscle Inhibition (AMI) of Vastus Medialis

    Time frame: First 4 weeks (28 days), 4 months (120 days) after the start of the season, and the last 4 months (120 days) of the season. 3 months (90 days) before the operation, 4 months (120 days) after the operation, and the last 4 months (120 days) of the season

    This measure evaluates the level of Anthrogenic Muscle Inhibition (AMI) in the vastus medialis muscle. Assessment Tool: Electromyography and Ultrasound Unit of Measure: Percentage (%)

Secondary outcomes

  1. isometric extension maximum knee with traction

    Time frame: First 4 weeks (28 days), 4 months (120 days) after the start of the season, and the last 4 months (120 days) of the season. 3 months (90 days) before the operation, 4 months (120 days) after the operation, and the last 4 months (120 days) of the season

    this test is used to obtain strength maximum knee extension. For To be able to measure, a cell of strain gauge load fixed to the stretcher where the test will be performed with the knee fixed at 90º. It will be carried out in the two legs, noting which of them is the dominant. Newton (N)

  2. The Single Leg Vertical Jump exercise

    Time frame: First 4 weeks (28 days), 4 months (120 days) after the start of the season, and the last 4 months (120 days) of the season. 3 months (90 days) before the operation, 4 months (120 days) after the operation, and the last 4 months (120 days) of the season

    It is a test used to being able to know the strength, power and capacity that the muscle has where the participant performs a vertical jump with a single leg, in this case it will be 3 times with one and 3 times with the leg contralateral. CM

  3. assessment surface electromyography

    Time frame: First 4 weeks (28 days), 4 months (120 days) after the start of the season, and the last 4 months (120 days) of the season. 3 months (90 days) before the operation, 4 months (120 days) after the operation, and the last 4 months (120 days) of the season

    the function neuromuscular and detect imbalances in muscle activation. HE surface electrodes will be used adhesives to the vastus medialis. To obtain electromyographic tracings patient will perform a contraction maximum isometric 6 seconds duration. microvolts
