Q: Marathon training Explain what type of diet would be best for a person training for a marathon.

This problem poses the issue of the physiology of metabolism as related to long duration, endurance type of activity, like a marathon. Clearly the dietary requirements of a marathon runner would be different from a sprint athlete. These differences arise from the way the muscles work in a sprint event versus an endurance event. How does diet of an athlete influence performances is the issue addressed in this problem.

Respiration

What is forced vital capacity and how does it relate to lung volumes What does the table indicate about vital capacity and subjects age, sex, height, smoker, asthmatic or athlete, do the findings support previous studies. What is peak expiratory flow and what is the effects of sitting, standing and lying on this measurement. (what effect do any of those positions have on the trachea) Studies to support findings
