False

Submit

10. ____________of fast-twitch motor units may occur under certain circumstances that allow an athlete to inhibit lower-threshold motor units and their place activate the higher-threshold motor units critical to optimal speed and power performance

Size principle

Reflex Potential

Selective Recruitment

Neuromuscular Junction

11. Which does not elicit bone growth?

Performing single joint exercises

Structural exercises that have direct force vectors through the spine and hip

Progressive overload

Variations in intensity, speed, and volume

12. When an athlete has a bilateral deficit the force of both limbs is _____ the sum of each individual limb.

Good

Bad

Indifferent

14. Type I muscle fibers can change to type II muscle fibers.

True

False

15. Which is not a physiological adaptation to resistance training?

Muscular Strength increases

Muscle fiber size increases

Creatine phosphokinase activity increases

Stored ATP increases

Mitochondrial density increases

Submit

17. Even though resistance training may cause an increase in capillaries, there is a decrease in capillary density due to muscle hypertrophy.

True

False

18. A physiological effect of overtraining is

An increased appetite

An increase in the joy experienced from training

A decrease in the desire to train

A decrease in sleep

19. Optimal muscle growth may result from maximizing the combination of and__ via training periodization

Mechanical and metabolic stimuli

Eccentric and concentric contractions

Morning and evening work outs

Dry land and aquatic exercises

Submit

21. Which does not occur during resistance training

Increase in myofibril volume

Increase in cytoplasmic density

Increase in sarcoplasmic reticulum and T-tubule density

Increase in sodium-potassium ATPase activity

Increase in muscle and blood pH

22. Muscle hypertrophy is associated with a ________________ in electromyography.

Increase

Decrease

No change

Muscle hypertrophy is associated with an increase in electromyography (EMG) activity. EMG measures the electrical activity produced by skeletal muscles. When muscles undergo hypertrophy, which is the enlargement of muscle cells, there is typically an increase in muscle fiber size and overall muscle mass. This increase in muscle size is often accompanied by an increase in electrical activity, as larger muscles generally produce stronger and more coordinated contractions, leading to higher EMG readings.
