Fysiskt aktivitet och dopamin
Physical exercise influences the central dopaminergic, noradrenergic and serotonergic systems. A number of studies have examined brain noradrenaline (norepinephrine), serotonin (5-hydroxytryptamine; 5-HT) and dopamine with exercise
Fysiskt aktivitet och hjärt- och kärlsjukdomar
The World Health Organization (WHO) states that substantial health benefits, for CVD risk reduction, can be achieved by moderate-intensity PA of at least 150 minutes a week, or vigorous-intensity PA of at least 75 minutes a week, or any combination of moderate and vigorous-intensity PA. It is also emphasises that any amount of PA leads to health benefits
There is clear evidence of an inverse linear dose-response relation between the volume of physical activity and all-cause mortality rates in men and women, and in younger and older persons. Minimal adherence to current physical activity guidelines, which yield an energy expenditure of about 1000 kcal x wk(-1) is associated with a significant 20--30% reduction in risk of all-cause mortality. Further reductions in risk are observed at higher volumes of energy expenditure [5]
Physical activity improves systolic blood pressure, angina symptoms and exercises tolerance in patients without re-vascularisation [6]. and patients with re-vascularisation achieve improved physical activity, the quality of life, and exercise tolerance (also 29% reduced risk of cardiac events 20% and/or lower readmission rates)[7].
A 2018 review reported "Resistance Training leads to improvement in cardiac autonomic control of diseased individuals" Also noting that only current physical activity is protective – sports participation in youth does not provide protection in later life unless activity is maintained[8].
