Two different studies were completed as part of this dissertation. First we examined the effects of EIMD on muscle strength, microvascular and mitochondrial function following 1, 24, and 48 after exercise. Seventeen young individuals completed both an electrical stimulation (ES) and voluntary (VOL) conditions. Assessments were performed at baseline, 1, 24, and 48 hours after exercise. Muscle strength decreased from baseline and remained lower from 1-48H after ES compared to VOL. Perceived recovery decreased after ES compared to VOL from baseline to 48H, and muscle quality was lower in both conditions. Soreness and muscle size increased following ES exercise compared to VOL. Microvascular function was reduced following sPLM after ES exercise compared to VOL. Mitochondrial capacity was impaired only after ES from baseline through 48H. Collectively, EIMD from ES impairs microvascular and mitochondrial capacity compared to VOL exercise. Next, we examined superficial femoral artery diameter during the exercise to evaluate changes in diameter and blood flow. The same individuals completed this study. Assessments were completed at baseline, and contractions 1,5,10,15,20,25,30,35, and 40. Antegrade and retrograde flow were quantified at baseline and each contraction stated above, and vascular conductance was calculated. No differences were detected for diameter, net blood flow increased after both conditions with the greatest flow occurring after ES. ES resulted in a greater increase antegrade flow and reduced retrograde flow. After the 20 contraction ES elicited greater conductance than VOL. The hypothesis was not supported, and there was no vasoconstriction. ES resulted in greater net blood flow.
