I am presenting the clinical case of a young man aged 24, who was participating in a sports class at his university, when he was participating in the running trial; he suddenly got dizzy, had an accelerated heart rate, chest pain and lipothymia, without losing consciousness. His colleagues intended to call the emergency services, but the young man suddenly got better and refused to be admitted ...

Post-exercise hypotension (PEH) plays an important role in the antihypertensive health benefits of exercise. While it has been shown that resistance exercise is effective at eliciting PEH, commonly consumed sports supplements may attenuate or completely eliminate response. Caffeine, a popular stimulant, often prior to PURPOSE: Determine effects pre-workout caffeine supplementation on PEH respon...

BACKGROUND Atrial fibrillation (AF) is associated with impaired exercise capacity. Oxygen uptake (VO2) kinetics determines cardiopulmonary performance during submaximal exercise, which may be impaired in patients with AF. AIM To study oxygen kinetics and cardiopulmonary performance in patients with AF without structural heart disease and the effects of oral sotalol on these parameters. PATI...

Recent investigations have demonstrated that at the onset of low-to-moderate-intensity leg cycling exercise (L) the carotid baroreflex (CBR) was classically reset in direct relation to the intensity of exercise. On the basis of these data, we proposed that the CBR would also be classically reset at the onset of moderate- to maximal-intensity L exercise. Therefore, CBR stimulus-response relation...

The relative contributions of aging and coronary heart disease to the impairment of functional capacity were assessed in 117 coronary patients, 117 age-matched healthy middle-aged men, and 62 healthy young men by utilizing a multistage treadmill test of maximal exercise. With aging alone, duration of exertion and maximal exercise heart rate were diminished while maximal systolic pressure increa...

This study assesses the safety of and physiologic responses to maximal repetition, dynamic, resistive weight lifting at 40, 60, 80 and 100% of maximal voluntary contraction compared with aerobic exercise using a maximal treadmill exercise test. Twelve men with coronary artery disease exercised to fatigue at 4 stations (overhead press, biceps curl, quadriceps extension and supine press). The ele...

background: new pressor protein (npp) is a human plasma enzyme structurally related to b–fragment of activated factor xіі (β-fxiia). the objective of the present study was to investigate the effects of npp and β-fxiia on systolic blood pressure and heart rate in bilateral nephrectomized rats.   methods: forty male wistar rats (250-300 g) were sham-operated or bilaterally nephrectomized under an...

the aim of the present study was to examine the effect of aerobic training and green tea supplementation on serum leptin and insulin resistance in overweight and obese men. for this purpose, 43 overweight and obese men were selected voluntarily and were included in four groups: control (body mass index 31.4+3.7, vo2max 39.3+3.8 ml/kg.min), green tea supplement (body mass index, 30.3±2.8 k/m2, v...

background: the objective of this study was to determine the heart rate and oxygen consumption of the elderly whilst frying. methodology: in 2010, a total of 31 subjects (11 males and 20 females) from sg. merab, selangor were participated in this study. they were aged between 60 to 83 years with a mean age of 67.06 years. they were asked to perform five minutes frying task and data were measure...
