During vigorous exercise, how is skeletal muscle pyruvate dehydrogenase regulated to increase its level of activity? In your response include metabolites that affect PDH kinase and therefore the activity of PDH.

During static muscle activity, there is a strong compressive effect from skeletal muscle contraction coupled with an absence of rhythmic muscle activity. Describe how this would change arterial pressure (afterload) and venous return (preload) compared with dynamic activity.

Briefly describe how lactate is formed within skeletal muscle during exercise. Consider the exercise intensity and the metabolic system required for lactate formation. Then, describe why lactate is physiologically relevant for an athlete and not just some waste byproduct that you want to clear.

You are obviously still breathing during an anaerobic activity like sprinting. If the skeletal muscle cells in your legs are performing lactic acid fermentation to produce the necessary ATP for their proper functioning, what is happening to the O2 gas you are breathing?
