background: to establish a balance between work (physical exercise) and human, the aerobic capacity (vo2max) could be used as a measure. assessing heart rate in association to physiological symptoms is the most commonly used tools for the assessment of fatigue during physical exercise. this study aimed to investigate the association between the aerobic capacity and the heart rate of workers fro...

Email:[email protected] Abstract Objective Children suffering from Cerebral Palsy (CP), exhibit movement limitations and physiological abnormalities as compared to normal individuals. The objective of this study was to assess mechanical efficiency and certain cardiovascular indices before and after an exercise-rehabilitation program in children with dipelegia spastic cerebral palsy (ex...

Recent studies have demonstrated that brief daily IAE (intermittent altitude exposure) was equally as effective as continuous altitude residence in inducing physiological adaptations consistent with altitude acclimatization. Although the positive benefits of IAE have been clearly defined, the potential negative consequences of IAE on health, specifically the immune system, remain undefined. The...

The purpose of this study was to elucidate the influence of inspiratory muscle fatigue on muscle sympathetic nerve activity (MSNA) and blood pressure (BP) response during submaximal exercise. We hypothesized that inspiratory muscle fatigue would elicit increases in sympathetic vasoconstrictor outflow and BP during dynamic leg exercise. The subjects carried out four submaximal exercise tests: tw...

The aims of the present study are twofold: 1) to investigate whether heart rate recovery (HRR) after a cycle ergometry test is affected by exercise training and 2) to test the ability of HRR to replicate the baroreflex sensitivity (BRS) changes that occur in response to an exercise training program in coronary artery patients. We randomized 82 coronary artery patients undergoing a residential c...

Measurement of VO2peak by CPET is the gold-standard method to evaluate aerobic fitness. The All Wales Adult CF Centre (AWACFC) established a specific service in 2022. PwCF were offered at clinic appointments. protocol comprised Godfrey cycle ergometer with rest, warm up, test and recovery phases. Pulmonary gas exchange, ventilation heart rate monitored continuously. In total 48 CPETs completed ...

Attenuation of exercise-induced increases in heart rate and cardiac output by chronic f3adrenergic blockade has been thought to conmpromise benefit of exercise training in patients with coronary artery disease (CAD). To assess this important issue, 35 CAD patients were evaluated by a 3-month walkjogcycle training program: 14 patients received no blocker (group 1), 14 received propranolol,' 30-8...

We investigated whether capsaicin ingestion (150 mg) enhances substrate oxidation associated with thermogenic sympathetic activity as an energy metabolic modulator without causing prolongation of the cardiac OT interval during aerobic exercise in humans. Ten healthy males [24.4 (4.3) y] volunteered for this study. The cardiac autonomic nervous activities evaluated by means of heart rate variabi...

BACKGROUND COPD increases the risk of cardiovascular problems. Dyspnea on exertion can be associated with COPD or heart failure or both. N-terminal-pro-brain natriuretic peptide (NT-pro-BNP) is a marker of cardiac dysfunction, and exercise testing can identify subtle heart abnormalities. OBJECTIVE To determine whether cardiac dysfunction adds to the mechanism of dyspnea caused primarily by im...

The purpose of this study was determine effects of ingestion carbohydrate-electrolyte beverage drink to improve exercise performance in the heat. Ten male subjects (age 1830 years) were subjected to cycle ergometer at 63.5 ± 3.3% of maximal O2 consumption (VO2max) with a pedal speed of 60 rpm until they became fatigued. They were given a drink of carbohydrate-electrolyte at a concentration of 6...
