Describe the general pattern of muscle strength with advanced age

I took a drug that blocked activation of the beta adrenergic receptor (receptor for the catecholamines).  What would happen as a result of taking this drug during an ACUTE bout of aerobic exercise?

Aging is best described as

What happens to muscle pH during exercise, and why would consuming a supplement that resists a change in pH in the muscle affect fatigue at exercise at high intensity

Why does acute exercise decrease water excretion from the body?

If I took a drug that reduced neuronal innervation of my type II muscle fibers, what might I expect to have happen and why

I took a drug that inhibited hepatic (i.e. liver) glucose production.  How might this affect fatigue during long distance aerobic events

Why is it possible for skeletal muscle to grow following resistance exercise even though the glucocorticoid, cortisol, is secreted at higher levels in response to the exercise sessions?

I took a drug that prevented an increase in mitochondrial content in the muscle in response to long term aerobic exercise training.  How would this drug minimize fatigue during exercise and why

I took a drug that increased insulin levels in circulation during a bout of aerobic exercise. What is likely going to happen because of this drug
