turnaround.
Forty men were treated once, then put through an eccentric protocol built to damage the quadriceps, then measured seven times over four days.
Multi Radiance’s reading of the curve below: placebo lost about 30% of its strength immediately after, the treated group about 6%.
The study
Both groups did the same damaging exercise. Immediately after, the placebo group had lost about a third of its strength. The treated group had barely moved, and was back past baseline while placebo was still short of it four days later.
Three doses were tested, so the trial shows how much light works rather than just that it does. Thirty joules per site came out best. Soreness and the blood marker for muscle damage were both lower too.

Maximum voluntary contraction as a percentage of each subject’s own baseline, from before exercise to 96 hours after. A single treatment was applied before the exercise. Values digitized from Fig. 2 of Antonialli FC et al., Lasers in Medical Science, 2014;29(6):1967–1976. 30 J gave the best result; 10 J and 50 J are shown faintly for scale.
It beat ice
A follow-up trial on the GameDay device compared laser, ice and both. Laser alone won. Ice alone did no better than placebo.
Use it instead of ice
In that same trial the laser did best on its own, so there is nothing to combine it with. One device, one step.
Either side of the session
This trial treated before the exercise; the ice trial treated after. Both beat placebo, so the timing is forgiving.
Dig deeper.
Eighty-plus peer-reviewed studies have been published on this technology. Here are three more.
These are research findings for super pulsed laser therapy, reported as published. GameDay is FDA cleared for the temporary relief of minor muscle and joint pain and arthritis, for muscle spasm, for relieving stiffness and promoting relaxation of muscle tissue, and for temporarily increasing local blood circulation. Performance and recovery outcomes described in this research are not cleared indications. Individual results vary.
