Filter by:Introduction: Neuromuscular fatigue is defined when the muscle becomes incapable of generating muscle power or strength after exercise or long repetitive activities. As well as, the inability to maintain optimum performance and generate maximum voluntary contractions during a physical exercise. When performing physical activity, the body's metabolic response increases proportionally to exercise to satisfy the demands of the human physiological. Part of the energy accumulated during exercise is lost to the environment in the form of heat and another part is maintained internally through the physiological control for thermoregulation. In addition, the muscle generates an electric signal important to determine its status regarding power and fatigue. Objective: To investigate the reduction of acute peripheral fatigue induced by isometric contractions from acupuncture and dry needling techniques, compared to absolute rest. Methods: This is a cross-sectional study and experimental study, with descriptive, analytical and quantitative approach. It follows the Consolidated Standards of Reporting Trials (CONSORT) guidelines. The volunteers will be gathered according to the eligibility criteria, and randomly divided in 3 groups: the control group (G1), the volunteers who will remain in prolonged rest; the acupuncture group (G2), in which volunteers will receive six needles in six acupoints in the non-dominant upper limb and the dry needling group (G3), in which the volunteers will receive application of six needles arranged in the non-dominant biceps brachialis.
The purpose of the study is to determine the effect of 16 weeks of running exercise on various parameters related to heart, vascular systems, blood, and muscle in untrained males 30-50 years old. Further, the investigators assess which of the above mentioned parameters may explain the increase of running performance most accurate.
