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 3 Planning 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
