Human growth hormone responses to repeated bouts of sprint exercise with different recovery periods between bouts.
This study examined the growth hormone (GH) response to repeated bouts of sprint cycling. Eight healthy men completed three trials consisting of two 30-s sprints on a cycle ergometer separated by either 60 min (Trial A) or 240 min (Trial B) of recovery and a single 30-s sprint carried out the day after Trial B (Trial C). Trials A and B were separated by at least 7 days. Blood samples were obtai...
متن کاملNutrient ingestion increased mTOR signaling, but not hVps34 activity in human skeletal muscle after sprint exercise
Nutrient provision after sprint exercise enhances mammalian target of rapamycin (mTOR) signaling. One suggested that nutrient sensor is the class III phosphatidylinositol 3-kinase, vacuolar protein sorting 34 (Vps34), not previously studied in human skeletal muscle. It is hypothesized that oral ingestion of essential amino acids (EAA) and carbohydrates (Carb) increases Vps34 activity and mTOR s...
متن کاملThe order of concurrent endurance and resistance exercise modifies mTOR signaling and protein synthesis in rat skeletal muscle.
Concurrent training, a combination of endurance (EE) and resistance exercise (RE) performed in succession, may compromise the muscle hypertrophic adaptations induced by RE alone. However, little is known about the molecular signaling interactions underlying the changes in skeletal muscle adaptation during concurrent training. Here, we used an animal model to investigate whether EE before or aft...
متن کاملATP synthesis and proton handling in muscle during short periods of exercise and subsequent recovery.
We used (31)P-magnetic resonance spectroscopy to study proton buffering in finger flexor muscles of eight healthy men (25-45 yr), during brief (18-s) voluntary finger flexion exercise (0.67-Hz contraction at 10% maximum voluntary contraction; 50/50 duty cycle) and 180-s recovery. Phosphocreatine (PCr) concentration fell 19 +/- 2% during exercise and then recovered with half time = 0.24 +/- 0.01...
متن کاملEffect of consecutive repeated sprint and resistance exercise bouts on acute adaptive responses in human skeletal muscle.
We examined acute molecular responses in skeletal muscle to repeated sprint and resistance exercise bouts. Six men [age, 24.7 +/- 6.3 yr; body mass, 81.6 +/- 7.3 kg; peak oxygen uptake, 47 +/- 9.9 mlxkg(-1)xmin(-1); one repetition maximum (1-RM) leg extension 92.2 +/- 12.5 kg; means +/- SD] were randomly assigned to trials consisting of either resistance exercise (8 x 5 leg extension, 80% 1-RM)...
