Explanation / Answer
16. The Rapid Recovery stage is associated with restoration of phosphagen stores as the elevated respiration primarily helps resynthesize the muscle's store of phosphagens ATP and PC.
Thus, the answer is C) the replenishment of phosphagens (ATP and PC)
17. The Slow Recovery stage is primarily responsible for the removal/re-conversion of lactic acid/lactate. This stage also supports the elevated metabolism functions taking place after exercise, including increased myocardial activity, which helps reduce the body temperature.
Thus, the answer is B) the energy cost of elevated myocardial (heart) activity
19. It has been shown that athletes with high carbohydrate diets are able to completely replenish their glycogen stores sooner. Therefore, high carbohydrate diets can be associated with enhanced replenishment of glycogen stores.
Thus, the answer is B) Enhanced replenishment of glycogen stores
20. Replenishment of glycogen stores is most rapid during the first few hours following training but may take several days to complete. Restoration of glycogen stores can be accelerated with high carbohydrate diet.
Thus, the answer is C) 46 hours with high carbohydrate intake
21. Lactate threshold is the exercise intensity at which the blood concentration of lactate and/or lactic acid begins to exponentially increase. Once this threshold is exceeded, lactate is produced faster than it can be removed, leading to a build up in the body, and exhaustion can be observed in the athlete.
Thus, the answer is C) at exhaustion
22. An active cool down during recovery from anaerobic work speeds up the removal of Lactic Acid. Active recovery after strenuous exercise clears accumulated blood lactate faster than passive recovery. Athletes are therefore advised to do light activity to speed up lactate removal.
Thus, the answer is A) engage in light and moderate work for several minutes following exercise
23. Oxygen is present in the blood bound to Hemoglobin. In muscles, oxygen storage occurs using the protein Myoglobin.
Thus, the answer is B) myoglobin
24. Exercise leads to a depletion on oxygen stores. During recovery, muscle oxygen stores can be transferred to the mitochondria for aerobic respiration. This aids restoration of oxygen stores during recovery.
Thus, the answer is C) the rapid restoration during recovery
29. Tendons are flexible but inelastic cords of strong fibrous collagen tissue attaching a muscle to a bone. They protect the connecting muscle from damage by acting as a sort of shock absorber.
Thus, the answer is B) protecting the muscle from damage that would otherwise occur from contraction
30. Action potentials signal muscle tissue to contract.This triggers calcium to release from the sarcoplasmic reticulum of the cells. The calcium ions then flow into the cytoplasm and bind to the troponin and tropomyosin molecules in the actin filaments of the muscle cells.This allows the troponin to change shape and expose the actin-myosin binding site. Myosin then connects to actin, and the formed complex forms a cross bridge that opens and closes and allows the muscle cells to contract
Thus, the answer is B) both actin and myosin bind to calcium which acts a cross-bridge, allowing for muscle contraction
31. The basic contractile unit of a muscle cell is the sarcomere, which consists of thin filaments of the protein actin and thicker filaments of the protein myosin.
Thus, the answer is D) sarcomere
33 Type I muscle fibers have the greatest aerobic capacity, while Type II have the lowest aerobic capacity.
Thus, the correct answer is A) Type IC
34. Type I muscle fibers have the slowest-contractile speed, the smallest cross-sectional area, the highest oxidative (aerobic) capacity, and the lowest glycolytic (anaerobic) capacity. They contract slowly and are able to hold a steady paced twitch for long durations without fatigue.
Thus, the correct answer is D) Type I fibers have relatively higher aerobic capacity and fatigue slower
