background and aim: in skeletal muscle, carnitine plays an essential role in the translocation of long-chain fatty-acids into the mitochondrial matrix for subsequent beta-oxidation. despite an abundance of literature describing the basic mechanisms of action of l-carnitine metabolism, there remains some uncertainty regarding the effects of oral l-carnitine supplementation on metabolism and exer...

The central governor model putatively explains the mechanism of endurance exercise-induced fatigue, however high-intensity fatigue strategies have not been investigated yet. This study aimed to examine how affects neural response alterations, as measured by electroencephalographic (EEG) recordings, in intermittent cycling. Neural responses were assessed measuring alteration brainwaves based on ...

OBJECTIVE To determine if assistive ergometer training can improve the functional ability and aerobic capacity of subacute stroke patients and if functional electrical stimulation (FES) of the paretic leg during ergometer cycling has additional effects. METHODS Sixteen subacute stroke patents were randomly assigned to the FES group (n=8) or the control group (n=8). All patients underwent assi...

To assess the effect of age on mechanisms exercise tolerance. Prospective observational study recruited 71 healthy individuals divided into two groups according to their i.e. younger (≤40 years age, N = 43); and older (≥55 28). All participants underwent maximal graded cardiopulmonary stress testing using cycle ergometer with simultaneous non-invasive gas-exchange central haemodynamic measureme...

The purpose of this study was to evaluate the efficacy of a unique program of ventilation-feedback training combined with leg-cycle exercise to improve exertional endurance and decrease perceived dyspnea in patients with chronic obstructive pulmonary disease (COPD). Thirty-nine patients (67.5 +/- 8.1 yr of age) with moderate to severe COPD (42.6% of predicted forced expiratory volume in 1 s) we...

Recent studies have suggested that an exaggerated blood pressure response to maximal exercise may be useful in detecting individuals who are prone to developing hypertension in later years. To examine the hypothesis that regular aerobic exercise results in a smaller blood pressure response to maximal exercise, 26 endurance-trained and 31 untrained individuals (matched on age and physical charac...

the aim of this study was to determine heat stress effect on physical capacity of semi-professional footballers in iran by means of oxygen consumption measurement, heart rate monitoring and wbgt assessment environmental conditions.this study compared two different thermal environmental conditions related to sub-maximal exercise and its effect on human physical capacity. thirty two male football...

[Purpose] This study was conducted to determine the influence of Taekwondo as security martial arts training on anaerobic threshold, cardiorespiratory fitness, and blood lactate recovery. [Subjects and Methods] Fourteen healthy university students were recruited and divided into an exercise group and a control group (n = 7 in each group). The subjects who participated in the experiment were sub...

JERRY J. MAYO, LEN KRAVITZ, AND JATAPORN WONGSATHIKUN. Detecting The Onset Of Added Cardiovascular Strain During Combined Arm And Leg Exercise. JEPonline. 2001;4(3):53-60. The purpose of this study was to determine the preferred distribution of arms to legs during combined arm-leg exercise. Fourteen subjects (7 males, 7 females) completed seven experimental testing sessions: one maximal oxygen ...
