According to the information presented in class, the improvement in performance in short-burst activities (e.g., <60 seconds) following a period of explosive power training (e.g, 2 months of high-intensity Wingate cycling bouts performed several times per week) is primarily the result of which of the following? a. Increased muscle mass and strength b. Improvements in glycolytic metabolic activity c. Improvements in CK enzyme activity d. Increased mitochondrial density e. Increased glycogen storage in the liver

| a. |
Increased muscle mass and strength |
|
| b. |
Improvements in glycolytic |
|
| c. |
Improvements in CK enzyme activity |
|
| d. |
Increased mitochondrial density |
|
| e. |
Increased glycogen storage in the liver |
Explanation:
The reason the improvement in performance is primarily the result of improvements in glycolytic metabolic activity is that this is the primary energy system used for short-burst activities. This energy system uses glycogen as its primary fuel source, and explosive power training has been shown to improve the body's ability to utilize glycogen for energy.
