Low level laser

To test the effectiveness of low level laser in recovery and performance of high level sportspeople, a study put twelve rugby players through a sprint test. The study was randomised, double-blind and placebo controlled, and showed the low level laser does indeed improve performance and recovery.

In the first week of the test, the players were familiarised with the sprint test. In the second and third weeks, the low level laser or a placebo was applied to each player.

The researchers studied:

  • Average time taken to complete the sprints
  • Best times of sprints
  • Fatigue
  • Blood lactate levels at 3, 10, 30 and 60 minutes after the sprint
  • Perceived fatigue

Those who received the low level laser therapy significantly improved average sprint time and fatigue index, and lower blood lactate levels. This study may open more doors for elite athletes and help the everyday player improve too.
