Abstract
The gaseous metabolism has been studied for a type of exercise involving only a limited amount of the musculature of the human body. For this purpose a simple ergometer, capable of being worked at any speed by the arms, has been constructed. The O intake rises much more slowly to its maximum value than it does in the case of exercise involving most of the muscles of the body, e.g., running or "standing running." These facts indicate that the lactic acid produced in excess by violent activity of a localized group of muscles may diffuse from them into the blood, and thence to other parts of the body. There would appear, therefore, to be the possibility of a type of exhaustion due to complete using up of the lactic acid precursor, when the exercise involved is localised in a small group of muscles.
