Across
- 2. maintenance of blood glucose through gluconeogenesis and indirectly via fat breakdown and mobilization
- 7. new glucose molecule can enter circulation and be used by skeletal muscle in a cyclic manner
- 11. It is released by motor neurons at neuromuscular junctions
- 12. increases with exercise levels and may be influenced by menstrual phase
- 15. increases with long-duration exercise
- 16. the circulating concentrations of epinephrine and norepinephrine increase during exercise according to density and duration.
- 17. At which of the following activities would the percentage of total energy expended from fat oxidation be highest?
Down
- 1. a motor neuron plus all of the muscle fibers it innervated
- 3. loss of muscle tissue as a natural part of the aging process.
- 4. a type of muscle cell
- 5. helps regulate fluid and electrolyte balance as well as blood pressure
- 6. which organ is where glucose is created then it can circulate back to muscle and be used as fuel
- 8. an effective ergogenic nutrition supplement when consumed in low to moderate doses
- 9. a cyclic operation from the skeletal muscle amino acid pool as well as from the catabolism and muscle protein and transamination occurs.
- 10. after excessive sweating and improper fluid balance can lead to
- 13. increase is relative to exercise stress; might abate during consistent training
- 14. decreases during exercise at high intensity due to alpha adrenergic inhibition insulin release from pancreas
- 18. contraction of skeletal muscle cells is powered by
