The effect of LED phototherapy on blood lactate level in the muscle was studied. A 450cm2 large red and near infrared
LED pad with its irradiance of 10mW/cm2 was applied for 10 minutes to brachial muscle and quadriceps muscle of thigh
to the participants before and after the Taekwondo contest. Blood samples from the participants were taken at 5 minutes
after the competition and 10 minutes after the recovery. The test results showed that the LED therapy (LEDT) before and
after the competition had a significant effect on the decrease of blood lactate level of the participants.
