18 Facts About Physical exercise

In terms of health benefits, the amount of recommended Physical exercise depends upon the goal, the type of Physical exercise, and the age of the person.

Physical exercise can include training that focuses on accuracy, agility, power, and speed.

Physical exercise is important for maintaining physical fitness and can contribute to maintaining a healthy weight, regulating the digestive system, building and maintaining healthy bone density, muscle strength, and joint mobility, promoting physiological well-being, reducing surgical risks, and strengthening the immune system.

People who participate in moderate to high levels of physical exercise have a lower mortality rate compared to individuals who by comparison are not physically active.

Moderate levels of Physical exercise have been correlated with preventing aging by reducing inflammatory potential.

The majority of the benefits from Physical exercise are achieved with around 3500 metabolic equivalent minutes per week, with diminishing returns at higher levels of activity.

Studies have shown that since heart disease is the leading cause of death in women, regular Physical exercise in aging women leads to healthier cardiovascular profiles.

Epidemiological evidence suggests that moderate Physical exercise has a beneficial effect on the human immune system; an effect which is modeled in a J curve.

Compliance with prescribed Physical exercise is low in individuals with cachexia and clinical trials of Physical exercise in this population often have high drop-out rates.

Neurobiological effects of physical exercise are numerous and involve a wide range of interrelated effects on brain structure, brain function, and cognition.

Aerobic Physical exercise induces short- and long-term effects on mood and emotional states by promoting positive affect, inhibiting negative affect, and decreasing the biological response to acute psychological stress.

Continuous aerobic Physical exercise can induce a transient state of euphoria, colloquially known as a "runner's high" in distance running or a "rower's high" in crew, through the increased biosynthesis of at least three euphoriant neurochemicals: anandamide, ß-endorphin, and phenethylamine .

Aerobic Physical exercise induces mitochondrial biogenesis and an increased capacity for oxidative phosphorylation in the mitochondria of skeletal muscle, which is one mechanism by which aerobic Physical exercise enhances submaximal endurance performance.

Physical exercise can improve health and well-being, as well as enhance community ties and appreciation of natural beauty.

Several mass Physical exercise movements were started in the early twentieth century as well.

Link between physical health and exercise was further established in 1949 and reported in 1953 by a team led by Jerry Morris.

Dr Morris noted that men of similar social class and occupation had markedly different rates of heart attacks, depending on the level of Physical exercise they got: bus drivers had a sedentary occupation and a higher incidence of heart disease, while bus conductors were forced to move continually and had a lower incidence of heart disease.

Effects of Physical exercise training appear to be heterogeneous across non-mammalian species.
