NUTRITION & FITNESS

VOCAB-NUTRITION

• Appetite• Empty-Calorie Foods• Foodborne Illness• Hunger• Minerals• Nutrient Density• Saturated Fats• Unsaturated Fats

VOCAB-FITNESS

• Anaerobic• Core Strength• FITT Formula• Isokinetic Exercise• Isometric Exercise• Isotonic Exercise

NUTRITIONSTUDENTS WILL UNDERSTAND THAT:

• there are different factors that influence food choices.• knowing how to interpret food labels will allow

you to make healthier food choices.• having a healthy meal plan will help you maintain

a healthy weight.

ESSENTIAL QUESTIONS-NUTRITION

• How do I make good consumer choices?• How does my meal plan help me stay healthy?

FITNESSSTUDENTS WILL UNDERSTAND THAT:

• Achieving and maintaining fitness requires age-appropriate intensity, duration and frequency of exercise.

• Lifetime fitness depends upon understanding how each fitness component is developed and measured and how to design and implement a personal fitness plan that supports a healthy, active lifestyle.

• Physical fitness contributes to improved quality of life.• Developing muscular strength and improving aerobic

capacity is beneficial in participating in all areas of sport and athletics.

ESSENTIAL QUESTIONS-FITNESS

• How do I develop an appropriate personal fitness program and maintain the motivation to commit to it?• How fit is healthy for someone your age?• What knowledge and attitudes must be acquired

to effectively manage your own health-related fitness?• What knowledge, skills and behaviors are

NUTRITION-WHAT IS IT???

• Nutrition is the study of nutrients and how the body uses them• Nutrients- the actual substances in food that your body

needs.

• 2 types of nutrients:• Energy Providers- Fats, Proteins, Carbohydrates (Carbs)• Those that help your body run smoothly- Vitamins,

Minerals, & H2O

• Nutrient Density- foods that provide large amounts of vitamins and minerals and few calories. (Example: Fruits and Vegetables)

IMPORTANT NUTRIENTS- FATS

• Are fats bad for you? NO• Used as fuel for the body• Promote healthy skin & cell growth• IF fats eaten aren't burned as energy or used as building

blocks, they're stored by the body in fat cells. • The body's way of thinking ahead: By saving fat for future

use, the body plans for times when food might be scarce.

• Types• Saturated Fat- Bad…found in meat and other animal

products, such as butter, cheese, etc. These fats are solid• Unsaturated Fat- Good…These are found in plant foods

and fish. These fats are liquid.

INFLUENCES

• What Influences your food choices?• Culture• Environment• Cost• Availability• Convenience• Peers• Advertising

INFLUENCES- APPETITE VS. HUNGER

• Appetite- the psychological desire for food (smell of baked cookies)• Often connected to memories and

feelings• Hunger-the body’s physical need for food.• Example: Dehydration, Diabetic

CALORIES

• Calories- A calorie is a unit of heat that measures energy available in food. • When you hear something contains 100 calories, it's a

way of describing how much energy your body could get from eating or drinking that food.

• Eating too many calories and not burning enough of them off through activity can lead to weight gain.

• Empty-Calorie Foods: Foods that offer few nutrients but do supply calories. (Example: Cookies & Cake)

HOW MUCH SHOULD YOU EAT?

•Boys (ages 9-13)•1,800-2,600 calories per day

•Girls (ages 9-13)•1,600-2,200 calories per day

5 FITNESS COMPONENTS

1. Flexibility- A joint’s ability to move through its full range of motion

2. Muscular Strength- The maximum amount of force a muscle group can exert against an opposing force

3. Muscular Endurance- The ability of the same muscle groups to contract for an extended amount of time without fatiguing.

4. Body Composition- The ratio of body fat to lean body tissue, including muscle, bone, water, and connective tissue

5. Cardiovascular Fitness- Exercises or activities that improve the efficiency of the heart, lungs, blood, and blood vessels

• How do we achieve each of these in PE class?

MUSCLE CONTRACTION

• Isokinetic- A muscle contraction in which the muscle contracts and shortens at constant rate of speed. (Recumbent bike/Elliptical)• Isometric- a form of active exercise in which

muscle tension is increased while pressure is applied against stable resistance (planks/Flexed arm hang)• Isotonic-exercise in which opposing muscles

contract and there is controlled movement (tension is constant while the lengths of the muscles change)

FITT PRINCIPLE

•F- Frequency: How often?•I-Intensity: How much effort?•T- Time: How long?•T- Type: What exercise?

ADDITIONAL TERMS

• Set- a group of repetitions performed for different exercises.• Rep- The number of times that you lift each

weight• Range of Motion- The degrees of motion

allowed around a joint• Core Strength- Strengthening of the muscles

around the spine and pelvic muscles• Anaerobic Exercise- Intense physical activity

that requires little oxygen but uses short burst of energy. (examples???)
