PED 127 Chapter 1 Notes
Many people do not become concerned
about their health until they experience health problems, or they
don’t like their bodies.
We cannot
control everything that influences our lives (many things are genetic),
but we can control factors that affect our life (diet, smoke, sleep,
stress). The information you are being exposed to can help you to
make choices toward maintaining a healthy lifestyle.
Reasons why people are not healthy:
- uneducated
- time
- cost
- tired
- self image
Fitness
consists of many aspects:
Emotional,
social, mental, spiritual, physical.
We concentrate
on the emotional and physical.
Physical
fitness: the capacity for sustained physical activity without
excessive fatigue.
There are
2 types:
a.
health fitness (components on page 2) These are performed
at a lower intensity for a shorter duration and less frequently
than:
b.
sport fitness programs- training/conditioning for a sport.
These programs do not usually develop all health fitness components
equally (a sprinter does not usually have a high level of cardiovascular
endurance)
5 health
fitness components:
1.
Cardiovascular endurance- also called aerobic endurance-
the ability to perform large muscle, whole body physical activity
of moderate to high intensity for a long time. It utilizes oxygen
for extended periods of time (see page 3)
2.
Strength- ability of a muscle to exert maximum force: 2 types
Isotonic-
force exerted by a muscle group as a body part moves.
Isometric-
force exerted against an immovable object.
3.
Muscle endurance- ability of a muscle of muscle group to
resist fatigue.
a.
dynamic- ability of a muscle group to contract repeatedly
against a submaximal resistance.
b.
Static- ability to maintain a certain degree of force
over a period of time.
4.
Flexibility- ability to move body joints through a
full range of motion without undue strain.
5.
Body composition- How much of your body is fat?
Over the
last 100 years there has been an increase in hypo kinetic disease-caused
by a lack of regular activity (page 4). They are seen in the elderly
but begin in preadolescence.
*PHYSICAL
ACTIVITY SLOWS DOWN THE AGING PROCESS.
