Title: Metabolism


1
Metabolism
  • The process in which your body gets energy from
    the food you eat
  • (How fast your body burns / stores the food you
    eat)

2
Basal Metabolism
  • The minimum amount of energy required to maintain
    life processes in the body
  • (Least amount of food you need to survive)

3
Calories
  • Energy value in food, measured in units of heat
  • Increased exercise increased calories burned
    loss of weight
  • 1 pound fat 3,500 calories

4
Aerobic exercise
  • Vigorous activity in which oxygen is continuously
    taken in for a period of at least 20 minutes
  • Oxygen is continuously being sent to the muscles
    while exercising

5
Aerobic examples
  • Jogging
  • Swimming
  • Cycling
  • Brisk walk
  • Strengthens heart and lungs to work more
    efficiently

6
Anaerobic exercise
  • Intense bursts of activity in which the muscles
    work so hard that they produce energy without
    using oxygen
  • Your muscles are using the oxygen already stored
    in your body, no new oxygen being utilized

7
Anaerobic examples
  • Sprinting
  • Weightlifting
  • Strengthen muscles over time

8
Types of resistance training
  • Isometric
  • Isotonic
  • Isokinetic

9
Isometric
  • Activity that uses muscle tension to improve
    muscular strength with little or no body movement
  • Ex Palms against each other

10
Isotonic
  • Activity that combines muscle contraction with
    repeated movement
  • Ex Push / Sit / Pull ups
  • Trunk twists

11
Isokinetic
  • Activity that involves resistance through an
    entire range of motion
  • Increases joint flexibility
  • Hammer strength machines
  • K

12
Planning a fitness program
  • Before you actually exercise, make sure you are
    physically able to exert yourself.
  • What if you have
  • Asthma ?
  • Bad knee ?
  • Sore back ?

13
Begin gradually
  • Ease your way into your workout program
  • Must enjoy it, do activities / exercises that you
    enjoy

14
Selecting the right activity
  • Where you live
  • Your interests
  • Level of health
  • Time and place
  • Personal safety
  • Do my activities meet the five components of
    fitness?

15
Basics of a program
  • 1) Overload
  • Working the body harder than it is normally
    worked
  • Increase reps, weight, time, distance

16
Basics cont
  • 2) Progression
  • - Gradual increase in overload necessary
    for achieving higher levels of fitness
  • - Gradually adding more weight, distance etc

17
Basics cont
  • 3) Specificity
  • Particular exercises and activities improve
    particular areas of health related fitness
  • Different activities / exercises for different
    goals

18
Injuries
  • Eventually going to happen
  • You must determine the severity of your injury

19
Injuries cont
  • If your injury requires medical attention, seek
    it a.s.a.p.
  • or
  • If your injury is not getting better within a
    week or so

20
What to do?
  • R.I.C.E. Principal
  • General first aid for the sprain, strain, sore
    muscle etc.

21
R.I.C.E.
  • Rest
  • Rest the injured body part or your entire body.
    By doing so, you are probably not going to
    aggravate your injury more than it already is,
    thus promoting healing

22
R.I.C.E.
  • Ice
  • Apply ice to your injured body part a.s.a.p.
    after you injure it. This will keep the swelling
    down. Ice frequently until injury is healed

23
R.I.C.E.
  • Compression
  • Wrap your injury with an ace bandage to keep
    swelling down. This will allow new blood cells
    to heal your injury faster

24
R.I.C.E.
  • Elevation
  • Elevate your injured body part higher than your
    heart. This will help drain the blood, keeping
    swelling to a minimum. This is important at
    night!
