LESSON 1: THE BASICS OF BODY COMPOSITION

BODY TYPES Ectomorph: body type is characterized by a low percentage of body fat, small bone size, and a small amount of muscle mass and size

Mesomorph: body type is characterized by a low-to-medium percentage of body fat, medium-to-large bone size, and a large amount of muscle mass and size

Endomorph: body type is characterized by a high percentage of body fat, large bone size, and a small amount of muscle mass and size

LESSON 1:THE BASICS OF BODY COMPOSITION

Body Mass Index: a way to assess body size in relation to height and weight

LESSON 1:THE BASICS OF BODY COMPOSITION

Body Composition: the relative percentage in your body of fat to lean body mass, including water, bone, and muscle is important to understanding a person’s overall health

Overweight: condition in which a person is heavier than the standard weight range for his or her weight

Obesity: medical condition in which a person’s ration of body fat to lean muscle mass is excessively high

LESSON 1:THE BASICS OF BODY COMPOSITION

Essential fat: minimum amount of body fat necessary for good health

1. insulates your body against the cold

2. cushions your internal organs, protecting them from injury

3. provides you with a valuable source of stored energy

Excessive Leanness

- may be defined as having a percentage of body fat that is below the acceptable range for your age and gender.

LESSON 2: INFLUENCES ON YOUR BODY COMPOSITION

Influences on Body Fat

• People who are overweight have a greater number of fat cells. They also have larger fat cells.

Lifestyle Behaviors

“You are what you eat!”

Energy Equation

• Calorie Intake: total number of calories you take in from food

• Calorie Expenditure: total number of calories you burn or expend

LESSON 2: INFLUENCES ON YOUR BODY COMPOSITION

Calorie Expenditure and Metabolism

Metabolism

• Process by which the body converts calories from food to energy

Resting Metabolic Rate

• Amount of calories you expend for body processes while at rest

• Gender

• Age: Decrease RMR

• Heredity

• Eating Habits (Slow or Speed up RMR)

• Eliminating Calories (Slows RMR)

• Physical Activity and Exercise (Increase RMR)

LESSON 2:INFLUENCES ON YOUR BODY COMPOSITION

Weight Control and Physical Activity

• FITT Principal of working out Frequency- how often I work out Intensity- how hard I work out Time- how long I work out Type- what specifically I’m doing while working out

LESSON 3: YOUR BODY COMPOSITION

Body Circumference: the distance around a body part

• Body Circumference tests measure girth• Males test around the waist• Females tests near the hips

LESSON 3: YOUR BODY COMPOSITION

Skinfold Measures: finger pinch test

Calipers: device used to pinch a fold of skin surrounding adipose tissue

Measured in millimeters and a good measure of body composition because 50 percent of all body fat is between muscles and skin

LESSON 4:MAINTAINING A HEALTHY BODY COMPOSITION

•Evaluate your needs•Be realistic•Design a personal plan•Become physically active•Keep track of your progress

LESSON 4:MAINTAINING A HEALTHY BODY COMPOSITION

Weight Control, Diet, and Exercise• Weight Loss: adjust your eating plan to reduce calorie intake while increasing calorie expenditure through physical activity or exercise

• Weight Gain: person should consume calories and maintain his or her physical-activity level (eat complex carbohydrates)

• Weight Maintenance: maintain a healthy eating plan with the same amount of calorie intake; also maintain moderate physical activity level

LESSON 4:MAINTAINING A HEALTHY BODY COMPOSITION

Benefits of Achieving Your Goals

•Increases energy

•Increases self-esteem

•Reduces stress levels

•Reduces risk of developing CVD or other diseases
