Physical Fitness

1. The body must experience a greater challenge than it is accustomed to in order to stimulate improvement.
4. Activity that uses oxygen-dependent energy production to support sustained movement. Examples include jogging, cycling, and swimming.
6. Physical activity that is planned, structured, and repeated to improve or maintain fitness.
8. The ability to perform daily activities, physical tasks, and exercise effectively without becoming overly tired.
9. The ability of a joint to move through its available range of motion.
12. A method for planning exercise using four variables: frequency, intensity, time, and type.
13. Exercise in which muscles work against a resistance, such as weights, resistance bands, or body weight.
14. The proportions of the body made up of fat mass and fat-free mass, which includes muscle, bone, and body water.
16. Training in a way that matches the fitness ability or skill you want to improve
19. How often you exercise.
20. A period of lower-intensity activity after exercise that helps the body transition toward rest
22. A group of repetitions performed before resting.
24. Preparation before exercise that gradually increases activity and helps the body get ready to move.

2. Any movement produced by your muscles that uses energy, such as walking, playing basketball, or taking the stairs.
3. One complete performance of an exercise.
5. The number of heartbeats per minute when a person is resting.
7. Specific Adaptation to Imposed Demands. The body adapts specifically to the type of demands placed on it.
10. High-intensity activity in which energy is supplied rapidly through pathways that do not depend directly on oxygen. Examples include sprinting and heavy lifting.
11. How long you exercise during a session.
15. The ability of a muscle or muscle group to repeatedly produce force or maintain a contraction over time.
17. How hard you exercise.
18. The ability of the heart, lungs, and circulatory system to deliver oxygen to working muscles during sustained activity.
21. The ability of a muscle or muscle group to produce force against resistance
23. The kind of exercise you perform.
