Selective Activation of the Rectus Abdominis Muscle During Low-Intensity and Fatiguing Tasks
Motor control electromyography biomechanics exercise
2015/5/7
In order to understand the potential selective activation of the rectus abdominis muscle, we conducted two experiments. In the first, subjects performed two controlled isometric exercises: the curl up...
Exercise Modality Effect on Bioenergetical Performance at VO2max Intensity
EXERCISE MODES TIME LIMIT OXYGEN UPTAKE KINETICS ENERGY EXPENDITURE
2017/4/19
Purpose: A bioenergetical analysis of different exercise modes near maximal oxygen consumption (V˙O2max) intensity is scarce, hampering the prescription of training to enhance performance. We assessed...
Influence of Posture on Pulmonary O Uptake Kinetics, Muscle Deoxygenation and Myolectrical Activity During Heavy-Intensity Exercise
muscle perfusion heavy cycling exercises NIRS VO slow component
2015/3/18
The aim of the present study was to test the hypothesis that compared to upright posture, slower oxygen uptake (VO2) kinetics resulting from exercise at the same relative metabolic load in the supine ...
A RAPID UP-REGULATION IN UCP3 TRANSCRIPTIONAL ACTIVITY IN RESPONSE TO MODERATE INTENSITY EXERCISE IN RAT SKELETAL MUSCLE
UCP FFA GLUT4 exercise
2015/3/17
Uncoupling protein 3 (UPC3) is a candidate protein transporter that uncouples oxidative phosphorylation
of mitochondrial respiration in skeletal muscle. A number of studies on UCP3 functions under v...
The influence of pedalling frequency on mechanical efficiency in exercises with the same intensity
Gross and net efficiency Cycle ergometer
2010/9/17
The aim of this work was the determination of the pedalling rate on the gross and net mechanical efficiency in efforts with the same intensity (250 W) as well as checking if the HR grows linearly alon...
