Evaluating Skeletal Muscle Mass and Peak Torque Deficits Post-ACL Reconstruction in Soccer Athletes with the Biodex

Abstract

This project explores the application of Biodex testing to evaluate muscular strength, balance and neuromuscular control of soccer players post ACLR. Our study includes one female and two male soccer players recovering from ACL reconstruction surgery. The goal is to evaluate their readiness to safely return to play by identifying strength imbalances and monitoring recovery process. As part of the assessment, the SECA machine was used to measure body composition, including muscle and fat mass, by sending a safe, low intensity electrical signal through the body. This data helps establish a baseline for lean muscle mass, supporting interpretation of strength outcomes. Biodex isokinetic testing provides objective data on quadriceps and hamstring strength, allowing for the identification of deficits in peak torque during flexion and extension which may increase the risk of reinjury. Peak torque is the highest force output during a repetition and is indicative of a muscle\u27s strength capabilities2. This data is used to guide individualized rehabilitation protocols, ensuring athletes regain optimal strenath and stability belore returning to pla
