Acupuncture and Dry Needling in Peripheral Acute Fatigue Reduction
Study Details
Study Description
Brief Summary
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.

No Intervention: Control Group The volunteers who will remain in prolonged rest (10 minutes for homeostasis plus 30 minutes of no intervention). |
|
Experimental: Acupuncture Group The volunteers will receive six needles in six acupoints in the non-dominant upper limb for 30 minutes. |
Procedure: Acupuncture
Six needled will be inserted in six already defined acupoints along the non-dominant upper limb for a period of 30 minutes.
|
Experimental: Dry needling Group The volunteers will receive application of six needles arranged in the non-dominant biceps brachialis for 30 minutes. |
Procedure: Dry needling
Six needles will be inserted in six predefined points along the volunteers non-dominant biceps brachialis for 30 minutes.

Outcome Measures
Primary Outcome Measures
- Perception of muscle fatigue [60 minutes]
Fatigue perception measured by Visual Analog Scale for fatigue assessment, graduated from 0,00 to 10,0 centimeters, being 0,00 no fatigue and 10,0 maximum fatigue.
- Muscle temperature [60 minutes]
Infrared thermographic Imaging analysis of acute peripheral muscle fatigue.
- Muscle fatigue [60 minutes]
Electromyographic activity (in microvolts) of the biceps brachii muscle to assess muscle fatigue through the median frequency (MF).
Other Outcome Measures
- Contraction time [60 minutes]
The time of intermittent isometric contractions was delimited by the number of valid contractions during each exercise
