1. Define the three energy pathways. For each pathway, identify two exercises that utilize the pathway. If you were training to run a marathon, which pathway would be the focal point of your training? What types of activities would you incorporate into your marathon training and why? How will an understanding of energy pathways help you in your future training endeavors?

Three different metabolic energy systems power your workouts — and your day. Here’s how each one works, and how to make the most of them all.
Most of us understand our bodies about as well as we understand our cars. We know we’re supposed to take them out for a spin once in a while, and keep them well fueled. But when it comes to grasping precisely how that fuel gets …show more content…

Though training the ATP-CP pathway will improve your explosive speed and power (so you can jump higher, sprint faster and throw farther), it won’t increase your storehouses of ATP-CP — or give you the ability to operate at full throttle for longer than a few seconds. That’s why activities like javelin throwing, Olympic weightlifting, and the 100-meter dash are “one-and-done” endeavors, even at the elite level. Most trained athletes need three to five minutes of rest before their ATP is replenished and they can perform near the level of their previous effort.
The “highlight reel” moments in soccer, tennis, basketball, hockey and many other sports are powered in large part by ATP-CP. But it also comes strongly into play whenever you need to move quickly (as when you’re making a dash to catch an elevator or grabbing a vase before it topples off a counter).
“As we age, we lose a lot of our ability to exert strength quickly,” says Scott. “So doing some of this training is important simply for maintaining quality of life.”
ATP-CP training doesn’t typically burn a lot of fat or build a lot of muscle, but that doesn’t mean you should cut it out. For one thing, it can be a lot of fun; and since you’re using lower reps, it probably won’t
