Locomotor muscle fatigue is not critically regulated after prior upper body exercise.
This study examined the effects of prior upper body exercise on subsequent high-intensity cycling exercise tolerance and associated changes in neuromuscular function and perceptual responses. Eight men performed three fixed work-rate (85% peak power) cycling tests: 1) to the limit of tolerance (CYC); 2) to the limit of tolerance after prior high-intensity arm-cranking exercise (ARM-CYC); and 3)...
متن کاملLess peripheral fatigue after prior exercise is not evidence against the regulation of the critical peripheral fatigue threshold.
TO THE EDITOR: Johnson and colleagues (2) report that cycling endurance time is substantially diminished and end-exercise peripheral locomotor muscle fatigue significantly lower when preceded by fatiguing arm cranking exercise. This is certainly an interesting study, and the findings are consistent with prior work that used dynamic single-leg knee extension exercise to exhaustion in one leg fol...
متن کاملEffect of expiratory muscle fatigue on exercise tolerance and locomotor muscle fatigue in healthy humans.
High-intensity exercise (> or =90% of maximal O(2) uptake) sustained to the limit of tolerance elicits expiratory muscle fatigue (EMF). We asked whether prior EMF affects subsequent exercise tolerance. Eight male subjects (means +/- SD; maximal O(2) uptake = 53.5 +/- 5.2 ml.kg(-1).min(-1)) cycled at 90% of peak power output to the limit of tolerance with (EMF-EX) and without (CON-EX) prior indu...
متن کاملLocomotor Muscle Fatigue Does Not Alter Oxygen Uptake Kinetics during High-Intensity Exercise
The [Formula: see text] slow component ([Formula: see text]) that develops during high-intensity aerobic exercise is thought to be strongly associated with locomotor muscle fatigue. We sought to experimentally test this hypothesis by pre-fatiguing the locomotor muscles used during subsequent high-intensity cycling exercise. Over two separate visits, eight healthy male participants were asked to...
متن کاملPeripheral fatigue is not critically regulated during maximal, intermittent, dynamic leg extensions.
Central motor drive to active muscles is believed to be reduced during numerous exercise tasks to prevent excessive peripheral fatigue development. The purpose of the present study was to use hypoxia to exacerbate physiological perturbations during a novel, intermittent exercise task and to explore the time-course and interplay between central and peripheral neuromuscular adjustments. On separa...
