A novel gravity-induced blood flow restriction model augments ACC phosphorylation and PGC-1$α$ mRNA in human skeletal muscle following aerobic exercise: A randomized crossover study

This study tested the hypothesis that a novel, gravity-induced blood flow restricted (BFR) aerobic exercise (AE) model will result in greater activation of the AMPK–PGC-1$α$ pathway compared with work rate-matched non-BFR. Thirteen healthy males …

Reliability of telemetric electromyography and near-infrared spectroscopy during high-intensity resistance exercise

This study quantified the inter- and intra-test reliability of telemetric surface electromyography (EMG) and near infrared spectroscopy (NIRS) during resistance exercise. Twelve well-trained young men performed high-intensity back squat exercise (12 …

Is leg compression beneficial for alpine skiers?

Background: This study examined the effects of different levels of compression (0, 20 and 40 mmHg) produced by leg garments on selected psycho-physiological measures of performance while exposed to passive vibration (60 Hz, amplitude 4-6 mm) and …

Knee extensor fatigue threshold is related to whole-body V̇O 2max

Purpose: Above a given exercise intensity, rapid muscle fatigue will occur. We explored the possibility of assessing torque threshold for peripheral fatigue during single-legged repetitive isometric knee extensor exercise. We hypothesized this …

The effect of elbow angle and external moment on load sharing of elbow muscles

To study elbow muscle load sharing we investigated the effect of external flexion-extension (FE) and pronation-supination (PS) moments and elbow angle on muscle activation and oxygen consumption (V̇O2).Two data sets were obtained. First, (n=6) …

Muscle oxygen consumption, determined by NIRS, in relation to external force and EMG

Local oxygen consumption in a muscle (V̇O2) can be determined by near infrared spectroscopy (NIRS). In principle it should be possible to use this measure to validate musculoskeletal models. However, the relationship between V̇O2 and external force, …
