About this trial
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.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Age between 18 and 45 years old
Playing in the Spanish National League (first or second category) or in the Madrid Futsal Federation in PRIMERA RFFM and PREFERENTE.
Both sexes
Have been playing futsal for at least 2 years
Disqualifiers
Operations other than an Anterior Cruciate Ligament injury (Cartilage, Meniscus, Ligaments).
Injuries to the knee of the contralateral lower limb. (sprains, fracture)
Muscle injuries or conditions in the affected or contralateral limb for less than 2 months (sprains, tibial periostitis, tendinopathies, tears).
Any infection must be reported after the intervention and will be excluded from the study.
Trial 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.

Anthrogenic Muscle Inhibition (AMI) Assessment Protocol
Other interventionThis 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.

Primary outcomes
1
Anthrogenic Muscle Inhibition (AMI) of Vastus Medialis
This measure evaluates the level of Anthrogenic Muscle Inhibition (AMI) in the vastus medialis muscle. Assessment Tool: Electromyography and Ultrasound Unit of Measure: Percentage (%)
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 seasonSecondary outcomes
1
isometric extension maximum knee with traction
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)
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 season2
The Single Leg Vertical Jump exercise
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
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 season3
assessment surface electromyography
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
