WHAT ARE THE FIVE COMPONENTS OF HEALTH RELATED FITNESS n 1. FLEXIBILITY = The ability to move a body part through a full range of motion. n 2.

Important Terms Resting Heart Rate- is the number of times your heart beats per minute. Usually between 60 -80 bpm. n Max Heart Rate- is the highest bpm recommended that your heart rate gets to during an exercise session. n Target Heart Rate- a range you should keep your heart rate during a particular exercise or program. n

Calculating Target HR n Formula for Target Heart Rate n 220 – Age = Max Heart Rate n 220 n MHR x 75% = Bottom end of Zone n 200 n x. 75 = 150 BPM MHR x 85% = Top end of Zone n 200 n – 20 yrs = 200 MHR x. 85 = 170 BPM Target Heart Rate Zone n 150 – 170 BPM (Maintain for a minimum of 20 minutes)

F. I. T. T F =Frequency I =Intensity T =Type n n T= time F = Frequency = How often you are exercising. (5 to 6 times a week) I = Intensity = How hard you are working out. T = Time = How long you are working out. T = Type = The type of exercise you do.

PRINICIPLES OF TRAINING n Principles of training The body becomes stronger and functions better if increased demands are placed upon it. n n Rep- one completion of an exercise movement Set- group of reps done consecutively (3 x 12@50%max)

Three Common Types of Stretching n A. STATIC STRETCHING = Stretching muscles beyond normal range of motion and holding the stretch for 15 - 30 seconds. n B. DYNAMIC STRETCHING = Slow continuous and controlled movement. n C. BALLISTIC STRETCHING = A bouncing motion that doesn’t allow your muscles to tell you its stretched too far.

Body Types n ENDOMORPH: A large, soft bulging body and a pear-shaped appearance. n High percentage of body fat n Short neck n Large abdomen n Wide hips n Round, full buttock n Short, heavy legs n

Define and distinguish the differences between “overweight” and “obesity. ” n Overweight - Exceed the desirable body weight by more than 10 percent, according to the height and weight charts. n Obesity – Exceed the desirable body weight by more than 20%.

Obesity Decreases quality of life n Increases your chances of getting diabetes and heart disease n Decreases your life expectancy n Increases healthcare costs by approximately 42% more a year out of pocket. n Can lead to injuries n

A calorie is defined as what? n n Is a measure of energy the body is able to produce from food. 3500 calories in 1 lb of fat n n n 1 gram of Carbohydrate = 4 calories 1 gram of Protein = 4 calories 1 gram of Fat = 9 calories n Ex. 1 gram is equal to the weight of a paperclip

To maintain your body weight: Positive caloric burn results in weight loss. n Positive caloric intake results in weight gain. n A balanced caloric intake and burn results in weight maintenance. n n Diet + Exercise = Weight Control

What is meant by the “long-haul” approach? • Weight loss is usually longer lasting if it is gradual. • It is recommended that you lose no more than 1 or 2 pounds per week.

Common Eating Disorders Anorexia nervosa n n n Some people become so obsessed with the fear of being overweight that they refuse to eat normally. Anorexics have a distorted body image.
