Previous biomolecular and animal studies have shown that a room-temperature far-infrared-rayemitting ceramic material (bioceramic) demonstrates physical-biological effects, including the normalization of psychologically induced stress-conditioned elevated heart rate in animals. In this clinical study, the Harvard step test, the resting metabolic rate (RMR) assessment and the treadmill running test were conducted ...

During sojourn to high altitudes progressive time-dependent increases occur in ventilation and in sympathetic nerve activity over several days and these increases persist upon acute restoration of normoxia. We discuss evidence concerning potential mediators of these changes including: a) correction of alkalinity in cerebrospinal fluid; b) increased sensitivity of carotid ...

Short-term changes of neurohormones can give important prognostic information in heart failure (HF) patients. In this study, we evaluate whether changes in plasma Norepinephrine (NE) and serum N-terminal pro-brain natriuretic peptide (NT-proBNP) after exercise training predict cardiac mortality in HF patients. We enrolled 221 HF patients (mean age 72.5±10.2year) followed-up ...

Pain sensitivity decreases with exercise. The mechanisms that underlie this exercise-induced hypoalgesia (EIH) are unclear. Our purpose was to investigate conditioned pain modulation (CPM) as a potential mechanism of EIH. Sixteen women completed pain testing during three sessions: painful exercise, nonpainful exercise, and quiet rest. Intensity and unpleasantness ratings to ...

Trained breath-hold divers (BHDs) are exposed to repeated bouts of intermittent hypoxia and hypercapnia during prolonged breath-holding. It has thus been hypothesized that their specific training may develop enhanced chemo-responsiveness to hypoxia associated with reduced ventilatory response to hypercapnia. Hypercapnic ventilatory responses (HCVR) and hypoxic ventilatory responses at rest (HVRr) ...

Cardiac and peripheral vasomotor factors contribute to the rapid pressor response at the onset of isometric handgrip exercise. We tested the hypothesis that age enhances the sympathetic and vasoconstrictor response at the onset of isometric handgrip exercise so that the pressor response is maintained despite a diminished cardiac function.

Low-intensity resistance exercise with blood flow restriction (BFR) has been shown to induce a prominent increase in muscle activation in response to muscle fatigue. However, the magnitude of muscle fatigue between continuous (Con-BFR) and intermittent BFR (Int-BFR, BFR only during exercise) is currently unknown. We examined the effect of Con-BFR ...

Reduced aerobic capacity, as measured by maximal oxygen uptake (VO2max), is a hallmark in cardiovascular diseases and strongly predicts poor prognosis and higher mortality rates in HF patients. While exercise capacity poorly correlates with cardiac function in this population, skeletal muscle abnormalities present a striking association with VO2max. This fact ...

Impaired skeletal muscle efficiency potentially contributes to the age-related decline in exercise capacity and may explain the altered hemodynamic response to exercise in the elderly. Thus, we examined whether 1) the ATP cost of contraction increases with age, and 2) this results in altered convective O2 delivery to maintain microvascular ...

We tested the hypotheses that, in humans, changes in cardiac output (CO) and total peripheral vascular resistance (TPR) occurring in response to isometric handgrip exercise vary considerably among individuals, and that those individual differences are related to differences in muscle metaboreflex and arterial baroreflex function. Thirty-nine healthy subjects performed a ...

Syncope which occurs suddenly in the setting of recovery from exercise, known as post-exercise syncope, represents a failure of integrative physiology during recovery from exercise. We estimate that between 50 and 80 % of healthy individuals will develop pre-syncopal signs and symptoms if subjected to a 15-min head-up tilt following exercise. ...

Breathing-retraining and helium-oxygen (heliox) have been used to improve exercise tolerance in COPD. We hypothesized that, in patients with COPD, exercise duration after exercise-training plus breathing-retraining and oxygen would be longer than after exercise-training plus heliox or after exercise-training plus oxygen alone. We also explored the short-term maintenance of gains ...
