Across
  1. 4. The rate of performing work; power. A function of energy output per unit of time.
  2. 5. Work performed per unit of time. Measured by the formula: work equal force times distance divided by time. A combination of strength and speed.
  3. 6. A loss of power to continue a given level of physical performance.
  4. 9. How often a person repeats a complete exercise session.
  5. 11. The principle that the body adapts very specifically to the training stimuli it is required to deal with. The body will perform best at the specific speed, type of contraction, muscle-group usage and energy source usage it has become accustomed to in training.
  6. 12. A group of repetitions of an exercise movement done consecutively, without rest, until a given number, or momentary exhaustion, is reached.
  7. 13. Subjecting a part of the body to efforts greater than it is accustomed to, in order to elicit a training response. Increases may be in intensity or duration.
  8. 15. Muscle action in which the muscle resists while it is forced to lengthen. This action is commonly called "negative" work, or "eccentric contraction," but, since the muscle is lengthening, the word "contraction" is misapplied.
  9. 18. Using oxygen.
  10. 19. Muscle action in which the muscle attempts to contract against a fixed limit. This is also sometimes called "isometric contraction," although there is not appreciable shortening of the muscle.
  11. 21. Reduction in size, or wasting away, of a muscle
  12. 22. A muscle contraction against a resistance that moves at a consistent velocity, so that the maximum force of which the muscle is capable throughout the range of motion to be applied.
  13. 23. An exercise session in which the intensity and duration of exercise are consciously alternated between harder and easier work. Often used to improve aerobic capacity and/or anaerobic endurance in exercisers who already have a base of endurance training.
Down
  1. 1. a type of exercise that suddenly preloads and forces the stretching of a muscle an instant prior to its concentric action.
  2. 2. The state of well-being consisting of optimum levels of strength, flexibility, weight control, cardiovascular capacity and positive physical and mental health behaviors,
  3. 3. A muscle contraction against a constant resistance, as in lifting a weight.
  4. 7. Muscle action in which the muscle is shortening under its own power. This action is commonly called "positive" work, or, redundantly, "concentric contraction."
  5. 8. Muscle fiber type that contracts quickly and is used most in intensive, short-duration exercised, such as weightlifting or sprints.
  6. 10. An individual completed exercise movement. Repetitions are usually done in multiples.
  7. 14. The amount of muscular force that can be exerted.
  8. 16. The force which a muscle is required to work against.
  9. 17. The maximum resistance with which a person can execute one repetition of an exercise movement.
  10. 20. A series of exercises, performed one after the other, with little rest between.
