Low level laser therapy (LLLT) has been documented to optimize human muscle performance with physical exercise. This study tested the effect of LLLT on physical strength training compared with strength training only.
The study involved 36 healthy, fit men using an 808 nm continuous wavelength laser, much like what we use in our office. The LLLT men showed an increase of 55% in strength on isokinetic dynamometry, significantly higher than the increases with exercise alone. Soon we may see LLLT commonly used to improve sports performance.
