PO-076 High and moderate intensity strength exercises to exhaustion activate different signaling cascades regulating protein metabolism in trained skeletal muscle

Effect of endurance training intensity (low, moderate and high) on the expression of skeletal muscle ATGL protein and serum levels of insulin and glucose in male diabetic rats

Background and Aim: The purpose of this study was to investigate the effect of endurance training intensity (low, moderate and high) on the expression of skeletal muscle ATGL protein and serum levels of insulin and glucose in male diabetic rats. Material and Method: 40 streptozotocin induced diabetic male Wistar rats were randomly assigned to five groups of eight, including low (DL , moderate ...

Testosterone and DHEA activate the glucose metabolism-related signaling pathway in skeletal muscle.

Circulating dehydroepiandrosterone (DHEA) is converted to testosterone or estrogen in the target tissues. Recently, we demonstrated that skeletal muscles are capable of locally synthesizing circulating DHEA to testosterone and estrogen. Furthermore, testosterone is converted to 5alpha-dihydrotestosterone (DHT) by 5alpha-reductase and exerts biophysiological actions through binding to androgen r...

on-kinetics in skeletal muscle contracting at moderate intensity

Carbohydrate Mouth Rinse Maintains Muscle Electromyographic Activity and Increases Time to Exhaustion during Moderate but not High-Intensity Cycling Exercise.

The aim was to investigate the influence of a carbohydrate (CHO) mouth rinse on the vastus lateralis (VL) and rectus femoris (RF) electromyographic activity (EMG) and time to exhaustion (TE) during moderate (MIE) and high-intensity cycling exercise (HIE). Thirteen participants cycled at 80% of their respiratory compensation point and at 110% of their peak power output to the point of exhaustion...

Effect of exercise intensity and hypoxia on skeletal muscle AMPK signaling and substrate metabolism in humans.

We compared in human skeletal muscle the effect of absolute vs. relative exercise intensity on AMP-activated protein kinase (AMPK) signaling and substrate metabolism under normoxic and hypoxic conditions. Eight untrained males cycled for 30 min under hypoxic conditions (11.5% O(2), 111 +/- 12 W, 72 +/- 3% hypoxia Vo(2 peak); 72% Hypoxia) or under normoxic conditions (20.9% O(2)) matched to the ...
