Answer/discuss the following questions and topics for a marathon runner:

(a) What energy system does this athlete primarily rely on?

(b) What energy substrates/macronutrients does this athlete rely on based on their energy system?

(c) What exercise intensity(s)/durations coincide(s) with this energy system?

(a) A marathon runner would primarily rely on their oxidative or aerobic system.
(b) A marathon runner would rely on carbohydrates, lipids, and proteins. However, they would rely on proteins the least.
(c) The oxidative system describes any exercise duration greater than 3 minutes with a low intensity.

Consider the main metabolic hormones discussed in class (testosterone, human growth hormone). What are the best resistance training methods/variations to enhance the availability of these hormones?

The best resistance training methods/variations to increase the availability of testosterone and human growth hormone would be heavy weight resistance training, short rest intervals, large muscle group/multi-joint exercises, moderate to high volume exercises, and about two years of resistance training experience.
