• Sedentary Lifestyle – a way of life that involves little physical activity

• What are three causes of having a sedentary lifestyle?

Number 1 answer

• The advancements in technology have created more sedentary lifestyles than any other factor.

Calculate Calorie Intake

• Handout, find out how many calories you should consume everyday.

Diabetes

• Diabetes is a serious disorder that prevents the body from converting food into energy.

• Type 1 diabetes can affect children or adults, but was traditionally termed "juvenile diabetes" because a majority of these diabetes cases were in children.

• Type 2 diabetes is the most common type.

Effects of Type 2 Diabetes

• Kidney Damage

• Eye Complications

• Foot Damage

• Blood Vessel and Heart Damage

Continued….

• Osteoporosis – a condition characterized by a decrease in bone density

• Metabolism – the process by which your body gets energy from food

*Additional calories

must be burned

through physical

activity or it will be

stored as fat!!!

Thinking Critically

Explain why watching television and walking affect your metabolism differently?

Why do you think many teens lead sedentary lifestyles?

Chapter 4 Lesson 2

• Cardio respiratory endurance

• Muscular strength

• Muscular endurance

• Flexibility

• Body composition

• Exercise

• Aerobic exercise

• Anaerobic exercise

Key Terms

• Cardio respiratory endurance – the ability of the heart, lungs, and blood vessels to utilize and send fuel and oxygen to the body's tissues during long periods of moderate to vigorous activities.

• Blood doping is the practice of boosting the number of red blood cells in the bloodstream in order to enhance athletic performance. Because such blood cells carry oxygen from the lungs to the muscles, a higher concentration in the blood can improve an athlete’s aerobic capacity.

• What is blood doping?

• Video

• Muscular strength – the amount of force muscle can exert.

• Can you improve your muscular strength? Yes or No

• Muscular endurance – the ability of the muscles to perform physical task over a period of time without being fatigued

• What is the hard rock 100?

• http://hardrock100.com/hardrock-about.php

• 100-mile run with 33,992 feet of climb and 33,992 feet of descent for a total elevation change of 67,984 feet with an average elevation of 11,186 feet - low point 7,680 feet and high point 14,048 feet (Handies Peak).

• The first 3 male finishers all finished their second Hardrock in impressive fashion, highlighted by Hal Koerner's time of 24 hours and 50 minutes

Muscular Endurance and Muscular Strength

Handouts• School Gym

• Flexibility – the ability to move a body part through a full range

• FitnessGram

• Body Composition – the ratio of body fat to lean body tissue. Including muscle, bone, water, and connective tissue such as ligaments, cartilage, and tendons.

• Exercise – purposeful physical activity that is planned, structured and repetitive and that improves or maintains personal fitness

• Aerobic exercise – any activity that uses large muscle groups and can be maintained continuously for at least 10 minutes three times a day or for 20 to 30 minutes once a week

• Anaerobic exercise – involves intense short bursts of activity in which the muscles work so hard that they produce energy without using oxygen

Warm-Up

• Why is hydrating before exercising important?

Chapter 4 Lesson 3Planning a personal activity

program• Overload – working the body harder

than it is normally worked

• Progression – the gradual increase in overload necessary to achieve higher levels of fitness

Ex. Push up

• Specificity - particular exercises and activities that improve particular areas of health related fitness

Ex. Swimming

• Warm-Up – an activity that prepares the muscles for work

Ex. Jogging, stretching

• Workout – the part of an exercise program which performance is at its highest peak

What is F.I.T.T.????

Fitness, Intensity, Time, Type

• Resting Heart Rate – the number of time your heart beats when you are not active.

Calculating heart rate

• How can you calculate your heart rate?

Chapter 4 Lesson 4

• Training program – a program of formalized physical preparation for involvement in sport or physical activity

• Hydration – taking in fluids so that the body functions properly

Can you over hydrate yourself?

Ex. Radio station contest

• Anabolic steroids – synthetic substance that is similar to the male hormone testosterone

• The Texas University Interscholastic League announced that one student tested positive for anabolic steroids out of 2,083 tests conducted at 135 schools. Less than 0.0006% of student-athletes tested failed the anti-doping protocol.

• Health screening – a search check for diseases or disorders that an individual would otherwise not have knowledge about of or seek help for.

• EX. Scoliosis

Chapter 4 Lesson 5

• Overexertion – over working the body

• Heat cramps – muscle spasms that result from loss of salt and water throughout perspiration

• Heatstroke – a condition in which the body loses the ability to rid itself of excessive heat through perspiration

Continued…..

• Frostbite – a condition that results when the body tissues become frozen

• Hypothermia – a condition in which the body temperature becomes dangerously low

• Skin cancer can be caused by prolonged exposure to the sun

The most dangerous hours for UV rays are from 10:00 am to 4:00 pm

Continued…..

• Muscle cramp – a spasm or sudden tightening of a muscle

What is the difference between a strain and sprain?

Sprain vs Strain

• A sprain is a condition resulting from damaging a muscle or tendon.

• A strain is an injury to the ligament surrounding a joint

Strain

Sprain

Fracture vs Dislocation

• Fracture – any break in the bone

• Dislocation – when a bone is forced from its natural position

Fracture

Dislocation

Tendonitis

• Tendonitis – when bands of fiber that connect muscles to the bones are stretched

Concussions

• Concussions – results from head blows to the head and can cause swelling of the brain
