Trace the plasma testosterone profile during the life span of a normal male. Describe the two phases of pregnancy from a metabolic standpoint. You may use a plot to aid you in your answer but you MUST explain the plot. Describe the impact of diet on muscle glycogen content before exercise, during prolonged exercise, and during LONG-TERM recovery from endurance exercise. Again, you may use a plot but you must explain the figure.
Strength training has an obvious influence on muscle hypertrophy.
This type of training has a less obvious influence on the neural factors involved in muscle contraction. Explain how increases in stroke volume and heart rate can account for a six-fold increase in cardiac output during exercise. If we monitor electrical activity of a muscle during isometric contraction against a constant load we find that the electrical activity increases over time. Describe the metabolic response of an endotherm to changes in environmental temperature. Include all the physiological responses to hot and cold ambient temperatures and any adjustments that can extend the range of environmental temperatures over which basal metabolic rate is sufficient to maintain body temperature.
