Despite positive associations between chronic physical activity and memory; we have little understanding of how best to incorporate physical activity during the day to facilitate the consolidation of information into memory, nor even how time spent physically active during the day relates to memory processes. The purpose of this investigation was to examine the relation between physical activit...

In this study, we tested the effect of acute exercise on long-term memory, specifically the timing of exercise relative to the memory challenge. We assessed memory via paragraph recall, in which participants listened to two paragraphs (exposure) and recounted them following a 35-min delay. Participants (n = 48) were randomly assigned to one of three groups: exercise prior to exposure, exercise ...

Objective—To review and determine the eVectiveness of exercise treatment in osteoarthritis of the knee. Methods—A computerised literature search of Medline was carried out searching between June 1966 and January 2000. Results—Twenty three randomised controlled trials were identified from the literature. Only three trials were suYciently powered. Small to moderate beneficial eVects of exercise t...

OBJECTIVE To review and determine the effectiveness of exercise treatment in osteoarthritis of the knee. METHODS A computerised literature search of Medline was carried out searching between June 1966 and January 2000. RESULTS Twenty three randomised controlled trials were identified from the literature. Only three trials were sufficiently powered. Small to moderate beneficial effects of ex...

Exhaustive exercise may generate oxidative stress in brain and reported findings are conflicting. Long term dietary restriction (DR) may be useful in the inhibiting of free oxygen radicals generated during exhaustive exercise in the brain of rat. Hence, in this study we evaluated beneficial effects of long term DR on the oxidative stress and antioxidant enzyme systems in brain cortex and lung i...

BACKGROUND Exercise referral schemes are one of the most popular forms of physical activity intervention in primary care in the UK and present an opportunity to better understand the factors related to exercise adherence. But standard schemes tend to be delivered over a short period and so provide information about the factors associated with short-term adherence. This retrospective register-ba...

Regular exercise has an antidepressant effect in human subjects. Studies using animals have suggested that the antidepressant effect of exercise is attributable to an increase of brain 5-hydroxytryptamine (5-HT); however, the precise mechanism underlying the antidepressant action via exercise is unclear. In contrast, the effect of 5-HT on antidepressant activity has not been clarified, in part ...

PURPOSE This study evaluated exercise-related predictors of successful long-term weight control in women by analyzing the extent to which sustained exercise participation and self-determination theory (SDT)-based exercise motivation variables mediated the impact of a behavioral weight control intervention on 3-yr weight change. METHODS Longitudinal randomized controlled trial consisting of a ...

This article reviews the role of free radicals in causing oxidative stress during exercise. High intensity exercise induces oxidative stress and although there is no evidence that this affects sporting performance in the short term, it may have longer term health consequences. The mechanisms of exercise-induced oxidative stress are not well understood. Mitochondria are sometimes considered to b...

Few studies have investigated the effect of exercise on homocysteine and 15-F21-isoprostane in animal models. The present study was designed to examine the effect of long-term exercise and/ or high cholesterol diet on MDA, 15-F21-isoprostane and total homocysteine in the aorta and plasma of rabbits. Methods: 56 male rabbits were divided into four groups: normal diet (control), normal diet wi...
