this was a tough one to decide where to post. it seems that pre exercise treatment with lasers and/or leds can lead to an increase in performance and recovery.

Effect of cluster multi-diode light emitting diode therapy (LEDT) on exercise-induced skeletal muscle fatigue and skeletal muscle recovery in humans.Leal EC Junior, Lopes-Martins RA, Rossi RP, De Marchi T, Baroni BM, de Godoi V, Marcos RL, Ramos L, Bjordal JM.

BACKGROUND AND OBJECTIVES: There are some indications that low-level laser therapy (LLLT) may delay the development of skeletal muscle fatigue during high-intensity exercise. There have also been claims that LED cluster probes may be effective for this application however there are differences between LED and laser sources like spot size, spectral width, power output, etc. In this study we wanted to test if light emitting diode therapy (LEDT) can alter muscle performance, fatigue development and biochemical markers for skeletal muscle recovery in an experimental model of biceps humeri muscle contractions. STUDY DESIGN/MATERIALS AND METHODS: Ten male professional volleyball players (23.6 [SD +/-5.6] years old) entered a randomized double-blinded placebo-controlled crossover trial. Active cluster LEDT (69 LEDs with wavelengths 660/850 nm, 10/30 mW, 30 seconds total irradiation time, 41.7 J of total energy irradiated) or an identical placebo LEDT was delivered under double-blinded conditions to the middle of biceps humeri muscle immediately before exercise. All subjects performed voluntary biceps humeri contractions with a workload of 75% of their maximal voluntary contraction force (MVC) until exhaustion. RESULTS: Active LEDT increased the number of biceps humeri contractions by 12.9% (38.60 [SD +/-9.03] vs. 34.20 [SD +/-8.68], P = 0.021) and extended the elapsed time to perform contractions by 11.6% (P = 0.036) versus placebo. In addition, post-exercise levels of biochemical markers decreased significantly with active LEDT: Blood Lactate (P = 0.042), Creatine Kinase (P = 0.035), and C-Reative Protein levels (P = 0.030), when compared to placebo LEDT. CONCLUSION: We conclude that this particular procedure and dose of LEDT immediately before exhaustive biceps humeri contractions, causes a slight delay in the development of skeletal muscle fatigue, decreases post-exercise blood lactate levels and inhibits the release of Creatine Kinase and C-Reative Protein.

I have undergone laser therapy on muscles, around joints, and on the head. I have also had led "goggles" designed to (like the lasers on the head) re-train the brain. The lasers on the muscles and around joints seem to increase recovery speed. I have always wondered at the placebo level of these benefits. Thanks for the study!

i remember when frank zane was at his heyday, he sold a line of audio tapes with led glasses that were designed to stimulate the various centers of the brain. at the time they seemed very effective. the laser/led therapy for muscles and joints appears to be effective but as alw3ays more research is needed. my biggest issue with these studies is that unless you are an elite athlete chances are pretty good your pc will not have access.

I remember when Billy Zane was a great actor.
