re: post-exercise metabolism:

"Endurance Exercise: Exercise of the intensity and duration commonly performed by recreational exercisers (e.g., walking for 30- 60 minutes or jogging at a pace of 8-10 minutes per mile for 20-30 minutes) typically results in a return to baseline of energy expenditure well within the first hour of recovery. The post-exercise calorie bonus for this type of exercise probably accounts for only about 10-30 additional calories burned beyond the exercise bout itself. In athletes performing high intensity, long duration exercise, the post-exercise energy expenditure may remain elevated for a longer period and could contribute significantly to total daily calorie burning. Ironically, such athletes are typically less concerned about this “extra” calorie burning and its implications for body weight regulation than are the recreational exercisers. The average person who does considerably less strenuous exercise will likely experience little meaningful contribution of this post-exercise bonus to their total daily calorie expenditure."

"Aerobic vs. anaerobic exercise
Studies published in 1992[5] and 1997[6] indicate that the level of aerobic fitness of an individual does not have any correlation with the level of resting metabolism. Both studies find that aerobic fitness levels do not improve the predictive power of Fat Free Mass for resting metabolic rate. However, recent research suggests that endurance training does indeed result in an increase in energy consumption. A recent study[7] has shown that the resting energy consumption of men who run for four hours a week is 54% higher than sedentary men.

This means it is unclear whether aerobic or anaerobic exercise are more effective in raising the resting metabolic rate (Basal Metabolic Rate). Anaerobic exercise, such as weight lifting, builds additional muscle mass, which is Fat Free Mass. Additional Fat Free Mass will lead to a higher resting metabolic rate according to the above studies. Also, while aerobic exercise is beneficial for cardiovascular reasons as well as direct calorie burning, recent studies seem to suggest that heavy endurance exercise also increases resting metabolism. However, it is unclear if light cardiovascular training has the same effect."
