2. Physical Fitness, Activity, and
Exercise
●
Physical activity is any bodily movement that is produced by
the contraction of skeletal muscles and that substantially
increases energy expenditure.
●
Exercise is planned, structured, and repetitive bodily
movement done to improve or maintain one or more
components of physical fitness, such as endurance,
flexibility, or strength.
●
Physical fitness is the ability to perform regular moderate to
vigorous levels of physical activity without excessive fatigue.
3. Benefits of Regular Physical

11. Conclusion
●
“Children who improved their physical
performance and health, through
training, were able to accomplish more
in all areas of their lives after training
than they could before.”
Notes de l'éditeur
This figure shows an actual image of a healthy heart. The heart is a muscle and like any other muscle gets stronger with regular use. A strong heart muscle can pump more blood per beat which allows the heart to work more easily. A strong heart also has good collateral circulation which improves the delivery of oxygen to the heart muscle.
Physical activity reduces risk of back pain by improving flexibility and improving musculo-skeletal strength and endurance
Physical activity is considered to be essential for long term weight control. It burns calories, increases the metabolic rate and promotes fat loss while maintaining lean body mass. These factors help a person avoid the problems of “creeping obesity” that plague most individuals as they get older.
Activity reduces the disease risks associated with Type 1 diabetes and also reduces a person’s risk of developing Type 2 diabetes
Physical activity reduces the risk of osteoporosis by increasing the peak bone mass early in life and slowing the normal decline in bone mass with age. Activity must be weight bearing to have some protective effect. Walking, jogging, weight lifting, aerobics are all considered to be good forms of activity to reduce risks of osteoporosis.
Activity slows down the normal aging process. It does this by slowing down the rate of acquired aging (aging due to poor lifestyles). There is a natural time dependent aging process that cannot be altered.
Activity improves not just the quantity of life but also the quality.
