Abstract

Aim: This study aimed to examine the effect of aerobic exercise with and without BFR on Blood Lactate, cortisol and PGC-1α response in human skeletal muscle. Method: On two different occasions, five healthy untrained male subjects (mean± SE; age: 33. 4± 1. 02 years, height: 173. 9± 4. 02 cm, body mass: 79. 64± 4. 69 kg), were required to perform (i) a BFR aerobic exercise at an exercise intensity of 40 % of VO2max; and (ii) similar exercise bouts without BFR (Ctrl). For each condition, baseline and 3 h post-exercise Muscle Biopsy samples (vastus lateralis) were performed for PGC-1α protein expression analysis. Venous blood samples were also collected at pre-exercise, immediately and 2 h post-exercise to measure changes in Blood Lactate and serum cortisol. Results: PGC-1α protein content was significantly higher (P < 0. 05) at 3-h post-exercise with BFR compared with Ctrl. Blood Lactate and serum cortisol did not significantly change from baseline to immediately after exercise and at 2-h post exercise. Conclusion: Metabolic stimuli are not a mechanism to mediate cell signaling network responsible for Mitochondrial Biogenesis. However, the addition of blood flow restriction during aerobic exercise induces an increase in PGC-1α to regulate Mitochondrial Biogenesis.
