Brief Summary:
Therapy with light emitting diodes LED is a good resource to accelerate the recovery of the athlete and reduce muscle damage caused by exercise Objective To evaluate the effects of LED therapy applied at different times on late muscle pain DOMS functional performance inflammatory and ergogenic response of rugby athletes Methodology Randomized crossover clinical trial composed of three groups that will receive treatment with LED at three different times Sample made up of rugby athletes of both sexes aged between 18 and 35 years On the first day of the study there will be an anamnesis where the participants will answer questions about personal data history of injuries and training time right after the participants receive weight height heart rate and measured blood pressure in addition to collecting a blood sample to standardize the individuals baseline values After the initial assessment participants will be randomized to not receive the LED CO or receive LED therapy at three different times before Lpré in the interval Lin and after Lpós the performance tests Then the modified Star Trek Balance Test SEBTm the Single Jump Test SGHT and the Triple Jump Test THT will be performed After that the Bangsbo Sprint BST test will be performed followed by the Yo-Yo level 1 intermittent recovery test Yo-Yo IR1 At the end of this test the subjects will remain at rest for 10 minutes and will be subjected to the same tests BST and Yo-Yo IR1 again They will be measured at the end of the second battery of tests heart rate blood pressure subjective perception of effort muscle pain threshold blood samples collected and repeated functional tests After 48 hours of the performance tests the blood sample will be collected again the functional tests carried out and they answered a Stress Recovery Questionnaire for Athletes RESTQ-Sport-76 At 7 14 and 21 days after the initial tests the same test and evaluation protocol will be performed but the participants will receive LED therapy before during or after the performance tests according to their randomization LED therapy will be performed on the rectus femoris vastus lateralis and vastus medialis muscles bilateral femoral semitendinosus and gastrocnemius biceps
Detailed Description:
Randomized crossover clinical trial composed of three groups that will receive LED treatment at three different times Sample made up of rugby athletes of both sexes aged between 18 and 35 years On the first day of the study there will be an anamnesis in which the participants will answer questions about personal data history of injuries and training time right after receiving weight height heart rate and blood pressure in addition to collecting a blood sample standardize the baseline values of the individual After the initial assessment participants will be randomized to not receive the LED CO or receive LED therapy at three different times before Lpré in the interval Lin and after Lpós of the performance tests Then the modified Star Trek Balance Test SEBTm the Single Jump Test SGHT and the Triple Jump Test THT will be performed Soon after the familiarization protocol with the Bangsbo Sprint test BST will begin with the participants positioned close to the initial marker photocell and the signal they must execute a maximum of 342 meters performing seven repetitions with twenty-five seconds duration for active recovery between sprints At the end of the sprints the participant will rest for 10 minutes and then perform the intermittent Yo-Yo level 1 recovery test Yo-Yo IR1 At the end of this test participants remain at rest for 10 minutes and then perform the same tests BST and Yo-Yo IR1 again At the end of the second battery of tests heart rate blood pressure perceived exertion blood sample and functional tests will be measured again After 48 hours of performance tests blood samples will be collected and functional tests will be carried out in addition to all participants answering the Stress Recovery Questionnaire for Athletes RESTQ-Sport-76 to quantify the recovery and psychophysiological stress during the test and recovery days At 7 14 and 21 days after the initial tests the same test and evaluation protocol will be performed but the participants will receive LED therapy before during or after the performance tests according to their randomization All participants will receive LED therapy at the three times only the application sequence will be randomized LED therapy will be performed at two points on the quadriceps two on the hamstrings and two on the gastrocnemius bilaterally At each point irradiation will be applied for 60 seconds with a wavelength of 850nm 20nm and an energy density of 8 joules per square centimeter Jcm2
