buildup.

Forty-eight men, twelve weeks, one strength program. The only thing that changed between the groups was when the laser was used.

100%Strength improvement over 30 days

A Multi Radiance figure. Vanin et al. report the gain as statistically significant (p < 0.05) without publishing a percentage.

The study

Same lifts, same twelve weeks, same tests. One group was treated before training, one after, one both, and one not at all.

The group treated before training gained significantly more than every other group, on both leg extension and leg press, measured at four, eight and twelve weeks. Timing was the only thing that separated them.

Maximum oxygen uptake as a percentage of baseline, across twelve weeks of treadmill training. Values digitized from Miranda EF et al., Lasers in Medical Science, 2018;33(4):719–727 — the companion timing trial, since the strength trial above publishes significance rather than percentages. Its authors report endurance improving three times faster than training alone.

What this means for you

Before, not after

Use it on the way into a session. P1 Prepare runs four minutes, which is short enough to fit.

It builds over a block

Gains were measured at four, eight and twelve weeks. This rewards showing up, not one big session.

One application is enough

The group treated before training outperformed the group treated twice. One four-minute program on the way in is all the trial needed.

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.
