Title: Physical Activity
1Physical Activity
- Any form or movement that causes your body to use
energy
2Physical Fitness
- Physical activity leads to physical fitness
- Physical fitness the ability to carry out daily
tasks easily and have enough reserve energy to
respond to unexpected demands
3Benefits of Physical Activity
- Physical
- Increases energy
- Cardiovascular system
- Respiratory system
- Nervous system reaction time
- Mental/Emotional
- Reduces stress
- Helps manage anger
- Increases self-confidence
- Positive self-concept
- Reduces mental fatigue more oxygen to brain
- Social Health
- Builds self-confidence cope better in social
situations - Opportunity to interact and cooperate with others
- relationships
4Level of Physical Activity(According to the CDC)
- 35 of teens (1 in 3) do NOT participate in
vigorous activity (20 minutes, 3 times a week) - 29 of teens attend daily PE 1991, 42
5Risks of Physical Inactivity
- Sedentary lifestyle a way of life that involves
little physical activity - 60 of US adults dont engage in recommended
activity - Only 20-24 of Americans get 30 min of exercise 5
days or more a week - Risks
- Unhealthful weight gain can lead to
non-communicable diseases (cardiovascular
disease, type 2 diabetes, and cancer) - Increased risk of osteoporosis a condition
characterized y a decrease in bone density,
producing porous and fragile bones - Reduced ability to manage stress
- Less opportunities to meet and form friendships
with active people who value and live a health
lifestyle
6Instead of
- Taking and elevator or escalator
- Playing video or computer games
- Getting a ride to a friends house
- Watching TV or taking a nap
- Taking the car through a car wash
7Fitting in Activity
- At least 60 minutes of moderate physical activity
- Doesnt have to be all at once
8Elements of Fitness
- Cardiorespiratory endurance
- the ability of the heart, lungs, and blood
vessels to utilize and send fuel and oxygen to
the bodys tissues during long periods of
moderate-to-vigorous activity - Muscular Strength
- The amount of force a muscle can exert (once)
- Muscular Endurance
- The ability of the muscles to perform physical
tasks over a period of time without becoming
fatigued - Flexibility
- The ability to move a body part through a full
range of motion - Body composition
- The ratio of body fat to lean body tissue,
including muscle, bone, water, and connective
tissue such as ligaments, cartilage, and tendons
9Improving your Fitness
- Exercise purposeful physical activity that is
planned, structured, and repetitive and that
improves or maintains personal fitness - Two categories of exercise
- Aerobic (oxygen) any activity that uses large
muscle groups, is rhythmic in nature, and can be
maintained continuously for at least 10 minutes
three times a day or for 20-30 minutes at one
time - Examples running, cycling, swimming, dancing
- Anaerobic (without oxygen) intense short
bursts of activity in which the muscles work so
hard they produce energy without using oxygen - Lifting weight
10Cardiorespiratory Endurance
- Improving
- Aerobic exercises heart and lungs are working
hardergetting stronger over time - F 3-5 times/week
- I Moderate THR zone 60-85 of your max HR
- T 20-60 minutes
- T aerobic activities
11Muscular Strength and Endurance
- Anaerobic
- Lifting Weights
- More weight, less reps strength
- Less weight, more reps endurance
- F 2-3 times/week
- I 1-3 sets, 8-12 reps
- T 30 to 60 minutes
- T Resistance training machines, free weights,
calisthenics
12Types of Resistance Exercise
- Isometric uses muscle tension to improve
muscular strength with little or no movement of
the body parts - Contracting muscles, pushing against a wall
- Isotonic combines muscle contraction and
repeated movement - Pushups, situps, free weights
- Isokinetic resistance is moved through an
entire range of motion at a controlled rate of
steed - Stationary bike, treadmill, machine weights
13Improving Flexibility
- Regular Stretching
- F 2-3 times/week
- I moderate
- T hold 15-30 seconds
- T static and or dynamic
14Types of Stretching
- Static
- Passive
- Active
- PNF (proprioceptive neuro-muscular)
- Dynamic
15Improving and Maintaining Bone Strength
- Resistance training
- Weight-bearing aerobic activities
16Training and Peak Performance
- Take care of your body
- Nutrition
- Hydration taking in fluids so the body
functions properly - Adequate rest
- Avoid harmful substances
- Steroids quick results, but bad for your health
- Supplements not approved by the FDA
- Begin training program
- A program of formalized physical preparation for
involvement in a sport or another physical
activity
17Safety First
- Health screening Physical before
participating - Using proper safety equipment
- Be alert of your surroundings
- Know your physical limits, play at your skill
level - Warm up and cool down
- Obey rules and restrictions
- Practice good sportsmanship
18Weather Related Injuries
- Hot-weather risks
- Overexertion overworking the body
- Heat exhaustion
- Heat cramps muscles spasms that result from a
loss of large amounts of salt and water through
perspiration - Heat stroke a condition in which the body loses
the ability to rid itself of excessive heat (core
body temperature rises) can lead to death - Cold-weather risks
- Frostbite a condition that results when body
tissues become frozen - Hypothermia a condition in which body
temperature becomes dangerously low
19Planning a Personal Activity Program
20Setting Goals
- What do you want to accomplish?
- Action Plan How can you achieve these goals?
- USDA recommends teens get 60 minutes of physical
activity every day
21Choosing Activities
- Cost
- Where you live
- Your level of health
- Time and Place
- Personal Safety
- Comprehensive planning
- Cross-training
- A variety of physical activities
22Important things to remember
- Overload working the body harder than it is
normally worked - Progression the gradual increase in overload
necessary to achieve higher levels of fitness - Specificity particular exercises and activities
improve particular areas of health-related fitness
23Parts of the Program
- Warm-up
- Workout
- Cool-down
- Monitoring your Progress
24Warm-up
- An activity that prepare the muscles for work
- Similar activity, but at a slower pace
- Stretching
25Workout
- FITT formula
- Frequency How often?
- Intensity How hard?
- Time How long?
- Type What did you do?
26Physical Activity Pyramid
Sedentary Activities seldom Ex) Watching TV,
video games, computer time
Flexibility Activities 2 days/week Ex) stretching
Anaerobic Activities 2-3 days/week Ex) resistance
activities
Aerobic Activities 3-5 days/week 20-60 minutes

27Monitoring Your Progress
- Resting Heart Rate the number of times your
heart beats in one minute when you are not active - Changes in strength or endurance the activity
becomes easier - Maxing out
