Although the effects of aerobic exercise on resting heart rate, heart rate variability, and blood pressure have been investigated, there are scant data on the effects of aerobic exercise on the circadian rhythm of such cardiovascular parameters. In this study, we investigated the effects of aerobic exercise on the 24 ...

As people age, they experience a decline in immune responses. Unusually heavy acute or chronic exercise could increase the risk of upper respiratory tract infection (URTI) whereas regular moderate physical activity may reduce URTI symptomatology. The purpose of the present study was to determine whether an aerobic exercise program would ...

PURPOSE: Exercise prescriptions for spaceflight include aerobic and resistive countermeasures, yet few studies have evaluated their combined effects on exercise responses after real or simulated microgravity. We hypothesized that upright aerobic capacity (VO2pk) is protected during a 60-d bed rest (BR) in which intermittent (40%-80% pre-BR VO2pk) aerobic exercise (supine ...

Non-alcoholic steatosis (non-alcoholic fatty liver disease [NAFLD]), now considered a metabolic pathway to advanced liver disease, cirrhosis and hepatocellular carcinoma, can also be explained by physical inactivity and increased dietary fat intake. No established treatment exists for this potentially serious disorder. The authors present the case of a 29-year-old man ...

Individuals infected with HIV experience numerous comorbidities caused by the disease progression and medications, lack of (or inability to perform) physical activity, malnutrition, or a combination of these causes. Common symptoms include loss of muscle mass, fatigue, lypodystrophy, lypoatrophy, and decreases in strength, functional capacity, and overall quality of life. ...

Central arterial compliance plays an important role in the functional abilities of the vasculature. Two active tripeptides, valine-proline-proline and isoleucine-proline-proline, were isolated from sour milk and were referred to as lactotripeptides (LTP). Because LTP appears to act as an angiotensin-converting enzyme inhibitor, it is plausible to hypothesize that LTP improves ...

Average human life expectancy has progressively increased over many decades largely due to improvements in nutrition, vaccination, antimicrobial agents, and effective treatment/prevention of cardiovascular disease, cancer, etc. Maximal life span, in contrast, has changed very little. Caloric restriction (CR) increases maximal life span in many species, in concert with improvements ...

Age is the major risk factor for cardiovascular diseases (CVD) and this is attributable in part to stiffening of large elastic arteries and development of vascular endothelial dysfunction (e.g. impaired endothelium-dependent dilatation, EDD). In contrast, regular aerobic exercise is associated with reduced risk of CVD. Endurance exercise-trained middle-aged/older adults demonstrate ...

While aerobic training and, to a lesser degree, resistance training are known to reduce blood concentrations of low-density lipoprotein cholesterol (LDL-C), little is known about the effects of a combination of aerobic and resistance training on LDL-C concentrations. The aim of the investigation was to examine the effects of 16 ...

Several studies have established that systemic sclerosis patients have a reduced exercise capacity when compared to healthy individuals. It is relevant to evaluate whether aerobic exercise in systemic sclerosis patients is a safe and effective intervention to improve aerobic capacity. Seven patients without pulmonary impairment and seven healthy controls were ...

BACKGROUND AND PURPOSE: Prior studies suggest that aerobic exercise may reduce both the brain atrophy and the decline in fractional anisotropy observed with advancing age. It is reasonable to hypothesize that exercise-induced changes to the vasculature may underlie these anatomic differences. The purpose of this blinded study was to compare ...

Oxidative stress that is mediated through NADPH oxidase activity plays a role in the pathology of hypertension, and aerobic exercise training reduces NADPH oxidase activity. The involvement of genetic variation in the p22phox (CYBA) subunit genes in individual oxidative stress responses to aerobic exercise training has yet to be examined ...

Emerging science suggests that aerobic exercise might modify the pathophysiology of Alzheimer's disease (AD) and improve cognition. However, there are no clinical practice guidelines for aerobic exercise prescription and training in older adults with AD. A few existing studies showed that older adults with AD can participate in aerobic exercise ...

Aerobic and resistance training are often performed concurrently by inactive individuals and those patients undergoing cardiac rehabilitation, despite contradictory findings that this mode of training may impair the development of maximal aerobic capacity (VO(2max)). The aim of the study, therefore, was to compare the effects of 16 weeks of aerobic, ...

Surgical patients often show physiological and metabolic distress, muscle weakness, and long hospital stays. Physical conditioning might help recovery. We attempted to identify the most responsive measure of aerobic fitness from a four-week pre-surgical aerobic exercise program (prehabilitation) in patients undergoing major bowel resection. Twenty-one subjects randomized two to one ...

BACKGROUND: Authorities advocate that resistance and aerobic exercise are essential for reducing risk factors for chronic disease and disability in older adults. However, the incremental effects of combined resistance and aerobic exercise compared with either modality alone on risk factors for disease and disability is generally unknown. METHODS: Participants were ...

We conducted a 4-month randomised controlled trial of home-based resistance training using exercise bands, amongst people with type 2 diabetes and co-morbidities limiting aerobic exercise capacity. The intervention did not improve HbA1c, anthropometric variables or functional capacity. We conclude that short-term use of exercise bands does not improve glycaemic control.

BACKGROUND: Animal studies indicate forced exercise (FE) improves overall motor function in Parkinsonian rodents. Global improvements in motor function following voluntary exercise (VE) are not widely reported in human Parkinson's disease (PD) patients. OBJECTIVE: The aim of this study was to compare the effects of VE and FE on PD ...

During ramp exercise the deoxy[Hb + Mb] pattern follows a sigmoid model [f(x) = f (0) + A/(1 + exp(-(-c +dx))], indicating a non-linear muscle blood flow (Qm)/oxygen uptake (VO25)-relationship. We hypothesised that in trained cyclists the sigmoid would display a rightward shift, due to an increased oxidative capacity and/or ...

While there are compelling observational data confirming that individuals who exercise are healthier, the efficacy of aerobic exercise interventions to reduce metabolic risk and improve insulin sensitivity in older people has not been fully elucidated. Furthermore, while low birth weight has been shown to predict adverse health outcomes later in ...
