Metabolism • The process in which your body gets energy from the food you eat • (How fast your body burns / stores the food you eat)
Basal Metabolism • The minimum amount of energy required to maintain life processes in the body • (Least amount of food you need to survive)
Calories • Energy value in food, measured in units of heat • Increased exercise = increased calories burned = loss of weight • 1 pound fat = 3,500 calories
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
Aerobic examples… • Jogging • Swimming • Cycling • Brisk walk • Strengthens heart and lungs to work more efficiently
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
Anaerobic examples… • Sprinting • Weightlifting • Strengthen muscles over time
Types of resistance training • Isometric • Isotonic • Isokinetic
Isometric • Activity that uses muscle tension to improve muscular strength with little or no body movement • Ex: Palms against each other
Isotonic • Activity that combines muscle contraction with repeated movement • Ex: Push / Sit / Pull – ups Trunk twists
Isokinetic • Activity that involves resistance through an entire range of motion • Increases joint flexibility • Hammer strength machines K
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 ?
Begin gradually • Ease your way into your workout program • Must enjoy it, do activities / exercises that you enjoy
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?
Basics of a program… #1) Overload • Working the body harder than it is normally worked • Increase reps, weight, time, distance
Basics cont… #2) Progression - Gradual increase in overload necessary for achieving higher levels of fitness - Gradually adding more weight, distance etc…
Basics cont… #3) Specificity • Particular exercises and activities improve particular areas of health related fitness • Different activities / exercises for different goals
Injuries • Eventually going to happen • You must determine the severity of your injury
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
What to do? • R.I.C.E. Principal • General first aid for the sprain, strain, sore muscle etc.
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
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
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
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!
