BACKGROUND The magnitude of the negative energy balance induced by exercise may be reduced due to compensatory increases in energy intake. OBJECTIVE TO ADDRESS THE QUESTION: Does increased exercise or physical activity alter ad-libitum daily energy intake or macronutrient composition in healthy adults? DATA SOURCES PubMed and Embase were searched (January 1990-January 2013) for studies that...

STUDY OBJECTIVES This study reports on the cardiorespiratory response to graded exercise in patients after venous switch operation for transposition of the great arteries. DESIGN Several small studies have documented a diminished exercise tolerance after Mustard repair for transposition of the great arteries, little information exists, however, about long-term cardiorespiratory exercise perfo...

Background Athletes demonstrate major adaptative changes in their hearts with high level of exercise. However the long term consequences of endurance training were not completely understood. We aimed to to explore the effect of long term endurance exercise on cardiac morphology and function, and diffuse fibrosis, and assess the significance of any discovered changes (correlation with documented...

conclusions in short term, using the self-management program can lead to increased exercise tolerance and decreased dyspnea in patients with copd; thus, this program is recommended as an effective way to improve the functional statuses of these patients. results there was no significant difference between the groups in exercise tolerance at base line; but, they were significantly different at t...

BACKGROUND In terms of motivation and long-term adherence, low-resistance exercise might be more suitable for older adults than high-resistance exercise. However, more data are needed to support this claim. OBJECTIVE The objective was to investigate the effect of low- and high-resistance exercise protocols on long-term adherence and motivation. METHODS This study was designed as an explorat...

BACKGROUND Pulmonary rehabilitation (PR) is an effective intervention for the management of people with chronic obstructive pulmonary disease (COPD). However, available resources are often limited, and many patients bear with poor availability of programmes. Sustaining PR benefits and regular exercise over the long term is difficult without any exercise maintenance strategy. In contrast to trad...

Huntington's disease (HD) is an inherited genetic disorder, characterized by cognitive dysfunction and abnormal body movements called chorea. Quinolinic acid (QA) is an endogenous metabolite of tryptophan in the kynurenine pathway. QA-induced alterations are similar to the symptoms of HD patients. Physical exercise has beneficial effects on the brain functions. Exercise increases production of ...
