Secondary prevention programmes can be effective in reducing morbidity and mortality from coronary heart disease (CHD). In particular, UK guidelines, including those from the Department of Health, emphasize physical activity. However, the effects of secondary prevention programmes with an exercise component are moderate and uptake is highly variable. In order ...

The aim of this paper is to evaluate the scientific background for the hypothesis that there is a connection between physical activity ...

Patients with unilateral vestibular lesions have a set of deficits requiring compensation based on the inherent plasticity of the central nervous system. In the 1940s, it was reported that patients with unilateral vestibular dysfunctions who exercised recovered faster than those who did not. The present prospective, randomized investigation aimed to ...

Deep cervical flexor (DCF) muscle impairment is common in patients with neck pain. Retraining function is often commenced with a motor relearning approach, requiring the patient to practice and hold a cranio-cervical flexion position in supine lying. Motor relearning requires multiple repetitions which is difficult to achieve if only exercising ...

Lifestyle modifications such as exercise and diet interventions in patients with coronary artery disease (CAD) are widely regarded as important, but little is known about their frequency in clinical practice and their impact on all-cause mortality. The JCAD study is a cohort study of 13,812 patients with CAD (≥75% stenosis ...

Exercise training can increase total Hb and red cell mass, which enhances oxygen-carrying capacity. The possible underlying mechanisms are proposed to come mainly from bone marrow, including stimulated erythropoiesis with hyperplasia of the hematopoietic bone marrow, improvement of the hematopoietic microenvironment induced by exercise training, and hormone- and cytokine-accelerated erythropoiesis. ...

Exercise training is a clinically proven, cost-effective, primary intervention that delays and in many cases prevents the health burdens associated with many chronic diseases.

Results suggest that an employee's probability of signing up for the program is related to her exercise behavior prior ...

Regular physical activity is associated with a reduced risk of coronary heart disease, as it probably modifies the balance between free-radical generation and antioxidant activity. On the other hand, however, acute physical activity increases oxygen uptake and leads to a temporary imbalance between the production of reactive oxygen and nitrogen ...

There is no consensus regarding the effects of mixed antioxidant vitamin C and/or vitamin E supplementation on oxidative stress responses to exercise and restoration of muscle function.

The purpose of this study was ...

Overwhelming evidence shows that physical activity and exercise promotion and prescription are effective in preventing and managing numerous chronic conditions. With physiotherapists commonly referred to as 'exercise prescription experts', an in-depth knowledge of exercise promotion and prescription is assumed. However, to date, no information exists about what is or should ...

Hemodialyzed patients demonstrate elevated oxidative stress and reduced functional status. Exercise induces health benefits, but acute exertion up-regulates oxidative stress responses in patients undergoing hemodialysis. Therefore, the aim of the present study was to examine the effect of L-carnitine supplementation on i) exercise performance and ii) blood redox status both ...

Oxidative stress is a natural physiological process that describes an imbalance between free radical production and the ability of the antioxidant defence system of the body to neutralize free radicals. Free radicals can be beneficial as they may promote wound healing and contribute to a healthy immune response. However, free ...
