Print on Demand. This book investigates the impact of doing mechanical work on the metabolic rate and efficiency of the human body as a machine. The author, an expert in nutrition, designed and built a bicycle ergometer - a device that records the amount of external muscular work performed by a person riding a bicycle - and used it to measure the calorific output of subjects performing work at different intensities. A series of experiments were conducted with three young men and a professional bicyclist, showing that the body can transform 20% of its energy into mechanical work. This finding contributes to our understanding of the efficiency of the human body and the relationship between energy expenditure and physical effort. Moreover, this research advances our knowledge of the physiological mechanisms underlying muscular work and energy production. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

During one Of the early experiments with this apparatus the subject performed a considerable amount Of mechanical work by raising and lowering a weight, and on those days during which the work was per formed there was a marked increase in the output Of carbon dioxid over the resting value. Subsequently, in connection with further experiments in these series, an improved form Of bicycle ergometer was devised in which a bicycle was so adjusted that the rear wheel pressed against the wheel attached to the armature shaft Of a small dynamo. From the amount Of electricity generated the amount Of external muscular work performed could be computed. The method Of calibrating the machine, and the description Of the machine itself, has been given in detail in an earlier bulletin Of this series, in an account Of experiments reported by Atwater and Benedict.
The inequalities Of the surface Of the tire, the slip, variations in tension Of spring, and numerous other factors rendered the limit Of error on this machine too large for the most satisfactory work, and 'hence a special form Of bicycle ergometer was constructed in which it was attempted to eliminate in 80 far as possible all known errors.
