Red Light Therapy: a Potential Strategy to Reduce Sports Injury Risk?

Starting soon · Not applicable

Conditions studied: Ankle Dorsiflexion

In brief

This study investigates whether near-infrared light therapy can acutely improve ankle dorsiflexion mobility and hamstring flexibility, two factors associated with sports injury risk. Healthy adult students will complete three randomized conditions: a control session, a 10-minute cycling warm-up, and a 10-minute exposure to a red and near-infrared LED panel (MITO LIGHT®). Mobility and flexibility will be assessed before and after each condition using the Knee-to-Wall Test (KWT) and the Active Knee Extension Test (AKET). The study aims to determine whether photobiomodulation may serve as a potential strategy to reduce musculoskeletal injury risk.
