There
are numerous benefits gained from physical activity. In fact, there
are more than 60 benefits that have been scientifically proven through
research. Here are just some of them:
Bodily Function Benefits
- Regular exercise is known to have beneficial effects on peripheral
and central circulation,
- skeletal muscle and myocardium, as well as
- lipid metabolism
- carbohydrate metabolism (Kavanagh, 2001).
- Leisure-time physical activity has been found to be associated with
reduced all-cause mortality, aside from genetic factors
- Physical activity has also been known to unmask various gastrointestinal
conditions such as infectious, inflammatory, or ischemic colitis.
- Moderate physical activity is associated with improved immune status
(i.e. decreased risk of contracting an upper-respiratory infection)
and lowered risk of developing various cancers (Burnham, 1998).
Skeletal Benefits
- Exercise early in life leads to a higher peak bone mass and can prevent
additional bone loss in postmenopausal women that would be caused by
a sedentary lifestyle
- Exercise including strength training has been shown to improve strength
in older adults and help maintain functional mobility and independence – even
if people begin exercising after age 80 (Burnham, 1998).
Disease Risk Factors
- participated in moderate or moderately vigorous activity experienced
a 50% reduction in risk of having a heart attack compared with inactive
men – even after adjusting for age, social class, BMI, smoking
habits, systolic blood pressure, heart rate, and blood lipids (Kavanagh,
2001).
- women who walked briskly for 3 hours per week had a 35% reduction
in coronary events compared with those who walked infrequently (Kavanagh,
2001).
- A seven-year study of women in Iowa found that women who engaged
in moderate activity for as little as once a week showed a reduced
mortality risk of 22%.
- Helps in controlling hypertension (Grundy, et al)
Decreased Risk of Mortality
- Increased physical activity improves insulin action and reduces
insulin resistance in obese subjects.
- Epidemiological data suggest that exercise alone and exercise combined
with weight reduction slow the transition from having impaired glucose
tolerance to developing type 2 diabetes
- Vigorous exercise (to the point of sweating and/or getting out of
breath) has been shown to lower risk of rectal cancer by 40 percent.
- Women engaged in 1-1/4 to 2-1/2 hours of brisk walking per week have
shown an 18 percent lower risk of breast cancer compared to inactive
women
- If physical activity is great enough to result in at least a 4.5
kg weigh loss, HDL cholesterol will be raised, and triglycerides will
be lowered (Grundy et. al, 1999).
Psychological Benefits
- Exercise appears to favorably alter mood by causing changes in brain
biochemistry similar to those produced by modern antidepressant medications
(Burnham, 1998).
- people who engage in regular leisure-time physical activity report
having fewer nonphysical problems such as poor social functioning,
adverse mental health, or role limitations due to emotional problems
than other subjects (Han et. al, 1998).
General Benefits
- A growing body of research shows that regular exercise may improve
sexual function for both men and women by improving physical and mental
health.
