Red light therapy, technically known as photobiomodulation (PBM), uses red or near-infrared (NIR) light to heal and regenerate damaged muscle tissue. While “red light therapy” is commonly used, PBM is the more precise term for this advanced treatment. It can be applied before exercise for pre-conditioning or afterward to enhance athletic performance and speed up recovery.

How Red Light Therapy (PBM) Works

Red light therapy boosts muscle recovery by increasing energy production at the cellular level. It stimulates the mitochondria — the cell’s center for energy production — leading to higher levels of ATP, the energy muscles need for movement. This extra energy allows muscles to work harder, recover faster, and reduces inflammation and oxidative stress.

Benefits for Athletes

Studies show that PBM can:

• Increase muscle mass after training
• Reduce muscle soreness and inflammation, including delayed onset muscle soreness (DOMS)
• Boost muscle performance, allowing athletes to do more reps and experience less fatigue
• Decrease muscle damage, as indicated by lower levels of creatine kinase (CK), a marker of muscle injury

How Red Light Therapy (PBM) is Used

Red light therapy can be applied using lasers or LED lights, targeting specific muscles. Depending on the recovery needed, red light, NIR light, or a combination of both is used. This technology is gaining popularity among professional and amateur athletes alike.

Red Light Therapy (PBM) in Sports Performance and Recovery: Study Highlights

Research shows that red light therapy (PBM) enhances muscle performance and recovery. While results vary in some cases, many studies have demonstrated positive effects. Below are key findings from several clinical trials:

• Increased Muscle Strength and Recovery — (Ferraresi et al., 2011): A clinical trial found that PBM applied after strength training significantly increased lifting capacity and improved knee extensor peak torque. The PBM group outperformed both the control and training-only groups in muscle strength gains.
• Reduced Muscle Fatigue — (Leal et al, 2010): PBM applied after moderate training reduced muscle fatigue in knee extensors, suggesting that it can help muscles resist fatigue, especially when paired with regular exercise.
• Enhanced Muscle Hypertrophy and Reduced Damage — (Ferrerasi et al., 2011): A placebo-controlled study on twins found that PBM applied after training promoted muscle hypertrophy, improved gene expression for muscle growth, and reduced markers of muscle damage (creatine kinase) and inflammation.
• Improved Muscle Power and Torque — (Baroni et al., 2010): When used as pre-conditioning before eccentric training, PBM improved muscle thickness and peak torque, showing its ability to enhance both strength and muscle size.
• Benefits for Elderly Populations — Toma et al. (Ferrerasi, 2012): PBM combined with strength training increased peak torque and work output in elderly women, making it a promising tool for improving muscle power in aging populations.
• PBM as a Pre-Conditioning and Post-Exercise Tool — (Baroni et al., 2010): PBM applied before strength training increased peak torque and 1-rep max strength in leg exercises, though using it both before and after exercise did not lead to additional benefits.

In Summary:

Red light therapy (PBM) is emerging as a powerful tool in sports medicine, aiding athletes and active individuals in faster recovery, injury prevention, and performance enhancement.
