Key Terminology

5. the volume of blood being pumped out with each beat of the heart
7. the greatest rate at which oxygen can be taken in and utilized during exercise
9. exercise system requiring only another person of near-equal size and strength
11. a muscle contraction that uses total involvement of the muscle fibers
12. a measure used to determine how effectively the heart functions as a respiratory organ
15. fibers that are aerobic in nature and are present in greater numbers in endurance-sport athletes
16. conditioning that is focused on specific requirements
19. a type of stretch involving alternating contractions and stretches
20. within a synergistic muscle group, a contraction of the agonist causes a reflex relaxation in the antagonist muscle, allowing it to stretch and protecting it from injury
21. the onset of a menses

1. a "dynamic" contraction that either involves a shortening or a lengthening of the muscle
2. a type of exercise that produces an isometric-type overload using the stretch reflex
3. an approach to conditioning that attempts to bring about peak performance while reducing injuries and overtraining
4. the ability to perform repetitive muscular contractions against some resistance
5. specific adaptation to imposed demands
6. a slow eccentric muscle contraction against resistance
8. a receptor in the muscle that senses change in the length of a muscle
10. maximum volume of air the lungs exchange in one breath
13. training is performed with a progressively increased load or resistance at a near-maximal rate
14. a position of extreme stretch on a given muscle group is assumed and held for a period of time
17. ability to do work or exert force against resistance
18. a muscle contraction that generates energy with no change in the length of muscle
