Metabolism Increase

Metabolism is the two-way process of synthesizing complex living tissue from simple nonliving foods and then the breakdown of these living tissues into simpler substances.
- The building-up process is called constructive metabolism or anabolism.
- The breaking down of living tissues to fuel and waste products is known as destructive metabolism or catabolism.
In the healthy adult who has attained his maximal growth, anabolism and catabolism proceed at equal rates, although of course in opposite directions. Thus weight remains steady.
In the resting state, metabolism proceeds slowly at a basal or minimal rate (”basal metabolic rate” or BMR) since there are no demands on the body other than to remain viable. But during exercise energy requirements increase. It is obvious that metabolism must accelerate in order to provide the extra fuel or calories necessary to sustain the added work load.
The principle sources of readily available calories in large quantities are glucose and fatty acids.
End products of their metabolism are carbon dioxide and water, both of which readily escape via the lungs. Except in exercise sustained for several hours, almost no protein is burned. This is fortunate. The end products of protein breakdown cannot find egress via the lungs but must be excreted by the kidneys. Since the kidneys shut down during exercise, a harmful accumulation of acid would result if protein were a significant fuel.
The Function Of Sweat
Sweating is useful chiefly as a means of losing heat. Because the human organism is only partly efficient, the metabolism of glucose and fatty acids yields work plus heat.
If the body were completely efficient, work and no heat would result. Thus exercise produces an increase in body temperature. After one to two hours of sustained activity, rectal temperatures of 101-103 degrees Fahrenheit are to be expected.
Sweat is an important defense against disastrous rises in temperature which may result in heat exhaustion and heat stroke. Believe it or not, the fit subject sweats better! In a recent experiment untrained subjects were exercised in a hot environment daily. At the outset they perspired moderately and lost copious amounts of salt. In a few days their sweat glands became acclimatized. They perspired more to get rid of more heat and cut back on salt losses to avoid the hazards of salt depletion.
Training of the mind is as inevitable as training of the body in the fit individual. The sportsman disciplines himself to ignore fatigue and to give forth with his best effort. Long surmised by coaches and trainers, this fact now has received scientific corroboration.
Trained and untrained subjects were examined in the laboratory. Each subject was asked to lift as much weight as he possibly could. Obviously the trained men could lift more. But that is not the point. Next, each subject was then given more weight than he said he was able to lift. At the very moment when the subject was about to hoist the weight a gun blast went off beside his head. By being thus distracted and startled the untrained men were able to lift more than previously. However, this was not so with the trained subjects-they already had “psyched” themselves up maximally.
The gun shot added nothing to their performance because they already had disciplined their minds for maximum effort.
This point was also confirmed by asking the subjects to shriek at the top of their lungs as they weight-lifted. Again, the untrained men lifted more. Shrieking made no difference to the fit subjects.
