Effects of cupping therapy on pain intensity, fatigue and performance after a 10km run

INTERVENTION: E02.190.233 This is a controlled, randomized and blind clinical trial, in which 80 runners, men and women, from the metropolitan region of Natal will be recruited. They will be allocated into the intervention group (sliding cup therapy will be applied with light suction on the quadriceps femoris for 10 minutes) and sham group (sliding cup therapy will be performed without suction for 10 minutes on the quadriceps femoris). CONDITION: Muscle Fatigue; Pain; Physical Functional Performance; Cupping Therapy PRIMARY OUTCOME: Intensity of pain and fatigue assessed using an analog scale SECONDARY OUTCOME: Isometric strength and power of the quadriceps femoris, assessed by isokinetic dynamometry and vertical jump. Muscle pain assessed by algometry and perception of recovery using a scale. INCLUSION CRITERIA: Street runners, with this practice modality for at least one year without interruption; Run routine at least twice a week; To be able to run 10 km continuously in the time interval between 40 and 60 minutes in, by less, one training session; Be between 18 and 45 years old; No cardiorespiratory changes or severe metabolic, proven through medical report; Do not report the presence of disturbances musculoskeletal disorders in the lower limbs, in the last 6 months, that have prevented the maintenance of training routine; Do not report any contraindications for the application of suction therapy, such as: blood clotting disorders, dermatological changes, active cancer and being undergoing a process severe infectious at the time of intervention; Never having used suction therapy.
