Key Takeaway
Meta-analysis and trial data showing red/NIR light therapy improves muscle recovery and can enhance exercise performance when applied before or after training.
Summary
This paper combines original research with meta-analysis to examine the effects of LED light therapy on muscle performance and recovery.
The key finding is that photobiomodulation applied before or after exercise can improve performance metrics and accelerate recovery. Pre-exercise application may increase work capacity, while post-exercise application may reduce muscle damage markers and soreness.
The research supports the use of red/NIR light as part of an athletic recovery protocol, though optimal timing and dosing parameters require further investigation.
Methods
- Randomized controlled trial component
- Meta-analysis of existing literature
- Assessment of pre-exercise and post-exercise application
- Measurement of performance and recovery markers
Key Results
- Improved time to exhaustion
- Reduced muscle damage markers (CK)
- Decreased delayed-onset muscle soreness
- Effects seen with both pre- and post-exercise application
Limitations
- Heterogeneous protocols in meta-analysis
- Optimal parameters unclear
- Individual response variability
- Long-term effects not well studied
