The latest research shows that Multi Radiance laser technology can reduce fatigue, speed recovery and more in athletes.
For many athletes, fall is more than just a season – it’s time to come back to the football, soccer or tennis field. It’s time to get active, connect with friends, and enjoy some friendly (or fierce) competition. However, as activity increases, so does the risk of injury. All types of sports and sports activities are accompanied by an increased risk of dislocations, sprains and simple strains; it is estimated that about half of all sports injuries are knee injuries.[i]
Clinicians have used various forms of light therapy to manage pain since 2002. The use of super pulsed laser therapy (SPLT) in Multi Glow in improving physical performance and markers related to post-exercise recovery has broadened its potential to treat fatigue-related injuries. Fatigue has been identified as a limiting factor in performance in almost all individual athletes in all sports and it is noted that injury rates increase with the accumulation of fatigue. When applied before exercise, SPLT protects muscles against exercise-induced fatigue and inflammation.[ii]
The SPLT has proven to be particularly useful in the world of recreational and competitive sports. The work of Leal et al. continues to demonstrate the value of using SPLT for ergogenic effects to build strength[iii] and increase endurance.[iv] A single dose of SPLT energy, delivered up to 12 hours before activity, can protect muscles from physical and oxidative damage after vigorous training and conditioning.[v]
Even with proper conditioning, form and technique, sports injuries do occur. Returning from a sports injury can be prolonged and difficult. Providers need to be assured that the injured tissue can withstand the demands of sport and that the muscle and joint damage has been sufficiently resolved.
Speed up recovery after injury
Immobilization and protection of the injured tissue area for the first one to three weeks allows undisturbed fibroblastic activity of the injured area which leads to proliferation and production of collagen fibers.[vi] Early or aggressive mobilization improves the production of type 3 collagen and weakens the tissues.[vii] However, a period of physical inactivity, especially between two to four weeks, can lead to losses in aerobic capacity.[viii] and without any evidence to suggest that it can be avoided.
Obviously, the best method to prevent atrophy is through use; this may be limited due to molding or bracing, or impractical due to premature tissue healing. by Paiva et al.[ix] evaluated the effects of SPLT applied at the end of a 12-week endurance program to assess changes over a four-week de-training period. Athletes who did not receive SPLT three times per week experienced a significant loss in both endurance (measured by VO2max) and exhaustion time (overall run time) over the four-hour period. weeks.
The activity interruption simulates a similar training loss due to injury. A significant loss of endurance (measured by VO2Max) as well as exhaustion time (total running time) were observed with the placebo groups. The group treated with SPLT experienced only a minimal drop in VO2max and attenuated the loss of oxygen used during running.
Applying SPLT during periods of non-use or downtime can help return to play faster with less loss of overall performance. The SPLT is an important tool for amateur and high performance athletes as well as those recovering from injury or surgical correction.
Improve athletic performance
Current evidence shows that SPLT with different wavelengths (different bands of the light spectrum, from red to near infrared) can enhance the activity of cytochrome c oxidase (complex IV of the mitochondrial respiratory chain), and therefore the mitochondrial function and ATP production, starting at five minutes. 24 hours after irradiation.[x] In addition, it has been shown at the cellular level that static magnetic fields (sMF) amplify the effect of SPLT, and that the synergistic effect of SPLT (with three wavelengths) and sMF leads to a transfer of improved electrons and, therefore, increased mitochondrial respiration. chain activity and increased ATP production are observed.[xi]
Other biological effects that explain how SPLT mechanisms can improve athletic performance relate to the direct release of nitric oxide from hemoglobin and nitrosylated myoglobin.[xii] or production by NO synthase [xiii] causing vasodilation, increased blood flow and increased availability of oxygen in muscle tissue.[xiv]
