Benefits of Regular Physical Activity: • Brainstorm: In groups of 3 or 4 come up with as many benefits of regular physical activity as you can think of! • Select someone to write all your groups ideas down. • You have 10 minutes!
Creating a Fitness Plan: • Set challenging but realistic goals • Choose exercises to best help you reach your goals • Begin exercising at a comfortable level • Do a variety of exercises • Follow the Training Principles: • Principle of Warm up • Principle of Cool down • Principle of Specificity • Principle of Overload • Principle of Progression • Principle of Fitness Reversibility
Warm-up • 5-10 minutes of easy exercise to warm and stretch muscles & increase blood flow • Specificity • A workout should • include a specific type of exercise to gain the desired fitness benefit • Overload • Workout must include exercise beyond what is usually done to gain additional fitness benefits • Training • Principles • Fitness Reversibility • Fitness Benefits are lost when training stops • Progression • Amount and intensity of exercise in a workout must be increased gradually • Cool-Down • 5-10 minutes of reduced exercise to help the heart rate & breathing rate, temperature, & circulation return to normal
Exercise Prescription • Your Exercise Prescription • Very similar to a medical prescription. A medical prescription will include the name of the medicine, the dose needed, and how often the medicine should be taken. • The exercise prescription is a breakdown of how often you need to work, how hard, the length of time per session, and the type of activity or exercise performed. These factors of exercise prescription are referred to as the principles of training or FITT principles.
The F.I.T.T. Principle/Formula • DEFINITION: Guidelines that help you set up a workout routine to fit your goals and fitness level • Help you get the most out of your exercise program
FREQUENCY • Refers to the number of times per week you engage in physical activity or exercise. • HOW OFTEN
INTENSITY • Refers to the difficulty or exertion level of your physical activity or exercise. • HOW HARD • Target Heart Rate • 220-Age
TIME • Refers to the duration of a single workout, usually measured in minutes or hours. • HOW LONG
TYPE • Refers to the particular type of physical activity or exercise you choose to do. • WHAT KIND
Physical Fitness Body’s ability to perform activity and to meet the demands of daily living while being energetic and alert. • Exercise is planned, structured and repetitive bodily movement done to improve or maintain one or more of the 5 components • 2 main kinds of exercise: • Aerobic • Anaerobic • Consists of 5 components of Health Related Fitness
AEROBIC EXERCISE • Vigorous, rhythmical, sustained activity that improves heart/lung function and body composition • Burns a lot of calories!
ANAEROBIC EXERCISE • Anaerobic means “without air” or “without oxygen.” • Short-lasting, high-intensity activity, body’s demand for oxygen exceeds the oxygen supply available. • Uses energy sources stored in the muscles • Examples include: • Weight Lifting • All types of sprints (running, biking, etc.) • Interval training • Any rapid burst of hard exercise.
Health Related Fitness - the ability of the heart, lungs, muscles, & joints to function optimally. • Cardio-Respiratory Endurance • Muscular Strength • Muscular Endurance • Flexibility • Body Composition 5 Components of Health-Related Fitness
Cardio-Respiratory Endurance • The ability of the circulatory and respiratory systems to supply oxygen during continuous physical activity • Helps your heart and lungs function more efficiently and improved your metabolic rate
Cardio-Respiratory Endurance • Frequency • 3-5 times per week • Intensity • 60-85% of target heart rate zone • Time • 20-60 minutes per session • Type • Any aerobic activity that increases heart rate
Examples of Exercises to Improve Cardio-Respiratory Endurance • Running/Pacer • Jumping Rope • Soccer • Ultimate Football • Biking • Dancing • Lance Armstrong-Tour de France • http://www.youtube.com/watch?v=FXPXHK7I1iQ
Muscular Strength • The maximum amount of force a muscle can produce in a single effort • How much you can lift, pull, push • How much power or force can you exert • ANEROBIC EXERCISE
Muscular Strength • Frequency • 2-4 times per week • Intensity • Heavier weight with less repetitions • Time • 30-60 minutes per session • Type • Anaerobic activities such as weight room
Examples of Exercise to Improve Muscular Strength • Weights -Max lifting • Squats • Deadlift • Bench Press • Push-ups • Pull-ups • World’s Strongest Man • http://www.youtube.com/watch?v=7mqSqwGJAMg
Muscular Endurance • Ability of the muscles to perform physical tasks over a period of time without becoming fatigued
Muscular Endurance • Frequency • 2-4 times per week • Intensity • Light weights, numerous reps • Time • 30-60 minutes per session • Type • Any activity allowing muscles to perform a physical task for a period of time
Examples of Exercise to Improve Muscular Endurance • Weights • Running/jogging • Swimming • Cycling • Pilates/Yoga • Push-up & Curl-up tests • Triathlons and Decathlons • Ironman Race • http://www.youtube.com/watch?v=WEoSdRvJQ0Q
Flexibility • The ability to bend and move the joints through a full range of motion. • Benefits of good flexibility: • Improved Performance • Decreased Injury Risk • Reduced Muscle Soreness • Improved Posture • Reduced Risk of Low Back Pain • Increased Blood and Nutrients to Tissues • Improved Muscle Coordination • Enhanced Enjoyment of Physical Activities
Examples of Exercise to Improve Flexibility • Dynamic Stretching • Static Stretching • Pilates • Yoga • Gymnastics • Gabby Douglass • http://www.youtube.com/watch?v=bmWICdhvyJw&feature=relmfu
Flexibility • Frequency • Daily stretching • Intensity • Stretch muscles and hold beyond its normal length at a comfortable stretch • Time • Hold each stretch 10-15 seconds; stretch 15-30 minutes daily • Type • Stretching allowing full range of motion
Body Composition • The percentage of body fat compared to the percentage of lean muscle tissue. • Too little body fat: • Is linked to problems with normal, healthy functioning • Can lead to problems with reproduction in women. • Too much body fat: • Increases the risk of many diseases, including type 2 diabetes, high blood pressure, stroke, heart disease, and certain cancers.
Body Composition • Can be measured in different ways: • Underwater Weighing • Waist to Hip Ratio • Body Mass Index • Skin Fold Testing
Lifetime Fitness Sports & Activities • Appropriate for most ages • Appropriate for most fitness levels • Some require little/no equipment • Some can be low to no cost • Examples: • Swimming • Running/Jogging • Walking • Cross County Skiing • Golf • Biking • Martial Arts
Nutrition: Words to Know • NUTRITION - is the science that studies how body makes use of food • DIET - is everything you eat and drink • NUTRIENTS - are the substances in food • CALORIES – See the next slide
What’s the deal with CALORIES? • A calorie is a unit of energy produced by food and used by the body • There are 3500 calories in a pound • Fat: 1 gram = 9 calories • Protein: 1 gram = 4 calories • Carbohydrates: 1 gram = 4 calories
6 Essential Nutrients • Substance that must be obtained from the diet because the body cannot make it in sufficient quantity to meet its need: • Carbohydrates • Protein • Fat • Vitamins • Minerals • Water
CARBOHYDRATES • Your body's main source of energy. • Most calories (55-60%) should come from carbohydrates. • Carbohydrates can be grouped into two categories: Simple and Complex. • Simple Carbohydrates = Sugars • Complex Carbohydrates = Starch & Dietary fiber.
Main Sources of Carbohydrates • Grain products • Breads • Cereals • Pasta • Rice • Fruits • Vegetables
PROTEIN • Needed for growth; building and repair or body tissues • The “building blocks” of the body • Secondary energy source
Main Sources of Protein • 2 Kinds of Proteins:
FAT • 2 Types: Saturated and Unsaturated • Maintains skin and hair • Cushions vital organs • Provides insulation • Production and absorption of certain vitamins and hormones.
Main Sources of Fat • Animal-based foods • Meats • Milk products • Oils • Nuts • Peanut butter
VITAMINS • Help to regulate chemical reactions in the body. • Vitamins cannot be made in the body, we must obtain them through the diet. • Vitamins are best consumed through a varied diet rather than as a supplement because there is little chance of taking too high a dose. • Vitamins come from a variety of sources • Eat a assorted & colorful diet!
MINERALS • Minerals are components of foods that are involved in many body functions. • Minerals are not a source of energy and are best obtained through a varied diet rather than supplements. • Minerals come from a variety of foods
WATER • Water helps to control our body temperature, carries nutrients and waste products from our cells, and is needed for our cells to function. • Most of our body weight (60-70%) is made up of water. • Drink at least 64 oz. per day • How do you know if you are drinking enough water? • Clear urine
Food Labels • Serving Size – The amount of food, such as 1 cup of cereal, 2 cookies, or 12 pretzels. It tells you how many nutrients are in that amount of food. • What is the serving size for this food? • Answer - ½ Cup • How many serving are in this container? • Answer - 4 Servings • How many calories are in 1 serving of this food? • Answer – 90 Calories • How many calories are in 3 serving of this food? • Answer – 270 Calories • Using the Percent Daily Value • Low = 5% or less of the Daily Value • Moderate = 6%-19% of the Daily Value • High = 20% or more of the Daily Value
Nutrition Facts Quiz • Directions: Analyze the nutritional value of this food. • ALL nutrients with a percent daily value should be listed in the chartList both the nutrient AND the percentage
