The goals is to analyze whether acupuncture and photobiomodulation have an effect on muscle fatigue, identify which is more efficient in reducing the fatigue effects, after the protocols applying individuals are able to perform the same workload, or improve it. It is a quantitative and experimental study, [72 active subjects (42 m. 32 f., 20 to 38 y), η: (age 25.79 y, h 172.01 cm, w 72.28 kg, BMI 24.37)]. Fatigue was assessed BOSCO modified protocol in a force plate, induced with 100 CMJ until failure. After the treatment protocols. Results show a significant difference after the intervention in groups A and D, (the sum of median heights, 2.60 cm and 2.45 cm, d 0.387 and 0.413, increasing h 14.44% and 12.36%, p < 0.001). Conclusion that acupuncture and photobiomodulation are efficient in minimizing fatigue, indicating that these treatment intervention protocols can improve muscular performance with jump height gain.

Background: Reduced peripheral and respiratory muscle strength correlates with impaired lung function in COPD, but whether diminishement in peripheral and respiratory muscle strength correlates with lung mechanis is unknown. Aims: To investigate whether spirometric and respiratory and peripheral muscle strength correlates with small airways obstruction evaluated by impulse oscillometry. Methods: Nighteen COPD GOLD II and twenty former smokers’ individuals were evaluated for lung function, lung mechanics, maximum inspiratory and expiratory pressure and hand grip strength test. Results: COPD presented reduced FEV1 and FEV1/FVC (p<0.001) compared to former smokers with no changes in FVC. In COPD the FEV1 and FEV1/FVC showed a negative correlation with BMI (P<0.05, R=-0.56 and -0.43, respectively). The total resistance of respiratory system and small airway resistance were reduced in the COPD compared to former smoke group. The COPD individuals showed a negative moderate correlation between FEV1 and impedance (R=-0,664; P<0.01); airway resistance (R=-0,593, P<0.05) and peripheral airway resistance (R=-0,547, P<0.05). The negative correlation was low in COPD individuals for reactance (R=-0,434, P<0.05) and proximal airway resistance (R=-0,480, P<0.05). These correlations were not found in the former smoke group. Hand grip strength measured in the right arm showed a moderate negative correlation with the maximal inspiratory pressure (R=-0,539, P<0.05) in COPD individuals. There was no correlation between PIMax and PEMax with none of the spirometric or oscillometric parameters (p>0.05) in COPD or former smokers’ individuals. Conclusions: Lung mechanics correlate with spirometric parameters in COPD patients but not with respiratory and peripheral muscle strength.
