NUTRITION
STUDENTS 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 does my meal plan help me stay healthy?
FITNESS
STUDENTS WILL UNDERSTAND THAT:
• Achieving and maintaining fitness requires ageappropriate 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 essential
to successful participation in fitness-oriented lifelong
activities?
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

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

EDUCATION????
•To promote lifelong fitness
concepts and ideas so that

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.
