The Science Behind Recovery and Performance
Whether you’re a professional athlete, a regular gym-goer or someone who enjoys staying active, recovery is just as important as the workout itself.
From muscle soreness and joint discomfort to physical fatigue, training places demands on the body. That’s why athletes are increasingly exploring different recovery techniques to help their bodies recover, maintain performance and stay consistent with their training.
One method gaining attention in the sporting and fitness world is red light therapy.
But what exactly makes it appealing to athletes, and how can it support an active lifestyle? Let’s take a closer look.
What Is Red Light Therapy?
Red light therapy (RLT), also known as photobiomodulation, uses specific wavelengths of red and near-infrared light to interact with the body’s cells.
Unlike UV light, red and near-infrared light do not rely on ultraviolet radiation. Instead, they are absorbed by cellular components involved in energy production and other biological processes.
This interaction may support mitochondrial function, helping cells produce adenosine triphosphate (ATP) – the energy currency used by the body.
By supporting cellular energy processes, red light therapy is being studied for its potential role in muscle recovery, exercise performance, inflammation and tissue repair.
5 Reasons Athletes Use Red Light Therapy
1. Supporting Muscle Recovery
Muscle recovery is essential for anyone who trains regularly. Intense exercise can cause temporary muscle damage, soreness and fatigue, making it harder to perform at your best during subsequent workouts.
Red light therapy is being researched for its potential to support muscle recovery by influencing cellular energy production and inflammatory responses.
Some studies suggest that photobiomodulation may help reduce exercise-induced muscle fatigue and soreness, potentially helping athletes return to training more comfortably.
2. Helping Manage Exercise-Related Inflammation
Inflammation is a natural part of the body’s response to exercise and plays an important role in the recovery process.
However, excessive or prolonged inflammation can contribute to discomfort and affect training consistency.
Red and near-infrared light have been studied for their ability to influence inflammatory pathways and support the body’s natural recovery processes.
This is one reason athletes are exploring red light therapy as part of a broader recovery routine.
3. Supporting Joint and Tissue Health
Athletes place considerable demands on their joints, tendons, ligaments and surrounding tissues.
Activities such as running, weightlifting, cycling and high-intensity training can create repetitive physical stress.
Red light therapy is being investigated for its potential to support tissue repair, cellular activity and joint comfort.
Near-infrared wavelengths are particularly interesting in this area because they penetrate further into tissue than visible red light.
While it isn’t a replacement for injury assessment or medical treatment, it may be a useful complementary approach to supporting an active lifestyle.
4. Improving Exercise Performance and Endurance
Recovery isn’t the only reason athletes are interested in red light therapy. Research has also explored whether photobiomodulation before exercise could influence physical performance.
By interacting with cellular energy processes, red light therapy may help support muscle function and exercise capacity.
Some research has reported improvements in measures such as muscle endurance and fatigue resistance, although results vary depending on the wavelength, treatment timing, dose and type of exercise.
For athletes looking to optimise their training, this is an exciting area of ongoing research.
5. Supporting Overall Recovery and Wellbeing
Athletic performance involves more than just muscles. Consistent training requires a balanced approach to physical recovery and general wellbeing.
Red light therapy is increasingly being incorporated into wellness routines alongside other recovery practices, including stretching, mobility work, adequate sleep, hydration and proper nutrition.
Its non-invasive nature and ease of use make it an appealing option for athletes who want to explore additional ways to support their bodies.
Red Light vs Near-Infrared Light: What’s the Difference?
Not all light therapy is the same. Different wavelengths interact with the body in different ways.
Red Light (630–660nm)
Red wavelengths are primarily absorbed by more superficial tissues, making them particularly popular for skin health and supporting surface-level tissue processes.
Near-Infrared Light (810–850nm)
Near-infrared wavelengths penetrate further into tissue and are commonly explored in research involving muscles, joints and exercise recovery.
For athletes, devices combining red and near-infrared wavelengths offer the opportunity to incorporate both into their recovery routine.
When Should Athletes Use Red Light Therapy?
The ideal timing depends on your training goals and the device being used.
Common approaches include:
- Before exercise: Some research has explored using photobiomodulation before training to support muscle performance and endurance.
- After exercise: Many people incorporate red light therapy into their post-workout recovery routine.
- On rest days: Recovery doesn’t stop when training does. Rest days can also be an opportunity to incorporate light therapy.
Consistency, appropriate treatment duration and following your device’s recommended protocol are important.
More exposure doesn’t necessarily mean better results, so it’s best to follow the manufacturer’s instructions rather than increasing session times unnecessarily.
Is Red Light Therapy Suitable for Everyday Athletes?
Absolutely. You don’t have to be a professional athlete to explore the potential benefits of red light therapy.
Whether you’re lifting weights, running, playing tennis, cycling, doing Pilates or simply trying to stay active, recovery is an important part of maintaining a healthy and sustainable exercise routine.
At-home red light therapy devices make it easier to incorporate light therapy into your routine without having to visit a clinic or recovery centre.
As with any wellness technology, results vary between individuals. Red light therapy should complement, rather than replace, established recovery practices and appropriate medical care.
Final Thoughts: Why Red Light Therapy Is Becoming Part of Athletic Recovery
Athletes understand that progress isn’t made in the gym alone. It’s also made during the time spent recovering between sessions.
With growing research into photobiomodulation, red light therapy is becoming an increasingly interesting addition to the world of sports recovery and performance.
From supporting cellular energy production to potentially helping manage exercise-related soreness and fatigue, there are several reasons athletes are exploring this technology.
Whether you’re training for your next competition or simply want to feel your best after a workout, red light therapy could be worth exploring as part of your recovery routine.
