The Impact of Partial Vascular Occlusion on Oxidative Stress Markers during Resistance Exercise . This study sought to examine the effects of partial vascular occlusion ( PVO ) on oxidative stress markers in response to resistance exercise and at rest in young resistance-trained males . 12 resistance-trained males performed 6 conditions in random counterbalanced order : rest ( R ) , low-intensity ( LIRE : 30 % 1RM ) and moderate-intensity ( MIRE : 70 % 1RM ) resistance exercise with or without PVO . Blood samples were obtained before and immediately after each condition and plasma protein carbonyls ( PC ) , glutathione ratio , oxygen radical absorbance capacity ( ORAC ) , and xanthine oxidase ( XO ) were evaluated . The addition of PVO resulted in significantly greater plasma PC and glutathione ratio in the rest condition . During LIRE the addition of PVO significantly attenuated plasma PC . The MIRE condition , independent of PVO , resulted in significantly higher PC concentration and glutathione ratio compared to the rest and LIRE conditions . The addition of PVO during MIRE resulted in a significant increase in PC . Thus , this study revealed that PVO increased oxidative stress at rest and enhanced the oxidative stress response to MIRE , but when combined with LIRE oxidative stress was attenuated . These findings suggest that the utilization of PVO during LIRE may alter ROS-induced accumulation in the blood which may influence cellular signaling .
