The Hierarchy of nutrient use dictates how our bodies treat nutrients depending on content of meal. Describe this hierarchy. (Basically what nutrients are used first)
AA are used first to provide substrates for protein synth in cells
Next carbs are used to replenish glycogen stores and provide glucose to tissues
Finally fat is used
Anything in excess is stored in adipose tissue
What is non-exercise activity thermogenesis?
Energy expended in digestion, absorption, metabolism and storage of ingested macronutrients

List three physiologoical changes that can be brought about by exercise
Cardioresp system adapts (Stroke vol inc due to larger stronger heart)
Number of cap in muscle inc to deliver O2 more efficiently(Inc in blood vol and RBC)
Inc in number and size of mitochondria in muscle cells
