O2 & CO2 and anaeorbic threshold

What biochemical rationale exists for measuring oxygen consumption, ventilation and carbon dioxide production to infer onset of anaerobic threshold during exerise?

Pulmonary ventilation and exercise

How can I justify that pulmonary ventilation does not limit aerobic exercise performance for most healthy people? Followed by a counter argument for the existence of pulmonary ventilation limitations.

Effect of exercise on elite runner

If elite runners run at an exercise intensity that does not cause appreciable accumulation of blood lactate, why do some of these athletes appear disoriented and fatigued and forced to slow down toward the end of the race?

Why someone is dizzy after doing a maximum lift exercise

What would cause a client to say to me after he completes a maximum lift standing press to say, " I feel slightly dizzy and see spots before my eyes." I am assuming that there is a physiological explanation for this? (I am thinking that there is a lack of blood to the brain.)

Aerobic exercise and mechanical efficiency

What would be practical implications for testing and knowing that someone has significantly lower economy of movement (mechanical efficiency) during running than they should?

Exercise limitations associated with COPD - Emphysema

What would be tests and measures which would probably include resting and exercise measures that would be used to determine exercise limitations in a patient with COPD? How would I use the results of these tests and measures (like: intepert the results whether they be static or dynamic variables) to determine the physiologica
