- n. A device for measuring the work capacity of a muscle or group of muscles during contraction.
Century Dictionary and Cyclopedia
- n. An instrument for recording muscular work; a recording dynamometer or ergometer: used especially in the study of muscular fatigue. The work recorded by the ergographs ordinarily employed is that done by a single finger pressing against a spring or pulling against a weight. In Mosso's instrument, the earliest form of the ergograph, there are three principal parts: the padded arm-rest, with arm-straps and brass tubes which hold the unused fingers in position; the weights, attached to a cord which passes over a pulley to a finger-cap adjusted to the lifting finger; and the recording carriage, which moves between metal guides with the movement of finger and spring, and carries a writing-point by which the ergogram or work-record is traced upon the smoked surface of a kymograph drum. An ergograph of this type is termed a weight ergograph. In other forms of the instrument, the compression of a spring replaces the pull-up of the weight: spring ergographs have been devised, for example, by Cattell and Binet. In yet other forms, among which Meumann's ergograph may be mentioned, there is no graphic record; the recording carriage and kymograph are replaced by a work-adder.
GNU Webster's 1913
- n. An instrument for measuring and recording the work done by a single muscle or set of muscles, the rate of fatigue, etc.

Examples
“As with strength of grip, so with endurance as measured by the ergograph; boys surpass girls at all ages, and this differentiation becomes very marked after the age of fourteen, after which age girls increase in strength and endurance but very slightly, while after fourteen boys acquire almost exactly half of the total power in these two features which they acquire in the first twenty years of life.”
“Perhaps the time will come when science and commerce will supply every tintype photographer with an ergograph and the knowledge to use it.”
“Then we shall hear at summer resorts and fairs, "Your ergograph on a postal card, three for a quarter.”
“We can step inside, harness our middle finger to the ergograph, lift it up and down forty-five times in ninety seconds, and lo!”
“The annual report of a board of health should give as clear a picture of a community's health during the past week or past quarter as the ergograph gives of the pupils mentioned on page 126.”
“If the arm lifts the weight of an ergograph until the will cannot overcome the fatigue, the mere seeing of the movement carried out by others whips the motor centers to new efficiency.”
“The one scientific instrument it seemed possible to use was an ergograph, a complicated and expensive instrument kindly lent to us from the physiological laboratory of the University of Chicago.”
“It now relies on purely psychological tests for its researches, and although it does not exclude the methods adopted in the laboratory, and the use of such accurate and trustworthy instruments as the esthesiometer and the ergograph, the school itself has become the chief field of experiment.”
“This has been clearly determined, for instance, by Féré, in the course of a long and elaborate series of experiments dealing with the various influences that modify work as measured by Mosso's ergograph.”
“Féré has shown that the slight stimulus to the skin furnished by placing a piece of metal on the arm or elsewhere suffices to increase the output of work with the ergograph.”
