Introduction: Resistance training with partial vascular occlusion (PVO) is an alternative training method that provides improvements in structural and functional adaptations and in strength levels that have been associated with the achievement of acute responses of muscle cells swelling. However, the optimum intensity to induce this cell swelling in muscle is unknown. The aim of study was to compare the acute responses on the perimeter biceps brachii and body composition with different intensities of PVO. Methods: To this end, 10 healthy men (21 ± 1.3 years) were recruited to conduct a neuromuscular training consisting of 3 sets to muscle failure with PVO (130% of systolic blood pressure) at 30% and 70% 1RM separated by one week. Were assessed changes in the perimeter of the biceps, the percentage of muscle mass and water content. Results: The biceps circumference increased significantly (p ≤ 0.001) after PVO30% (34.16 ± 0.95 cm) and 70 % (34.06 ± 0.93 cm). The amount of water was increased (5.33 ± 30% 1.26 %, 6.02 ± 70% 1.53%) but the differences were not significant. Finally, no changes were recorded in the percentage of muscle mass. Conclusion: The findings support the use of neuromuscular training PVO with low intensity (30% 1RM) to generate acute muscle cell swelling in healthy young subjects. Future research should evaluate the acute effects of muscle edema with gold standard techniques such as ultrasound, and associated the acute responses with chronic adaptations of muscular hypertrophy.
