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.
