Study on the Effects of Red LED Light Exposure on Enhancing Athletes'Recovery After Fatigue
This study aims to analyze the effects and durability of red LED light exposure on the recovery of athletes from various sports after fatigue.The study first administers red light therapy to the left and right calves of athletes from martial arts,judo and diving.Athletes are then required to complete a questionnaire on subjective recovery perceptions every morning and evening.The selected indicators in the questionnaire include muscle soreness,muscle swelling,calf fatigue and weakness,and overall recovery feeling.Each question is to be answered according to a Fatigue Recovery Rating Scale.The study found that judo athletes showed significant improvements in all these indicators after light exposure(P<0.05),whereas the improvements of martial arts and diving athletes were not significant(P>0.05).Subsequent experiments focused on judo athletes,further confirming the significant effects of red light exposure on improving calf recovery(P<0.05).Additionally,this effect was found to have a certain degree of durability.This study provides important reference value for the application of red light LED light in sports training and recovery.
