Development of a Human Atlas of Strengths

In spite of the technical progress achieved during this century, muscular energy of man is still required to perform many tasks. In order to assess these tasks, operator strength must be considered. This paper describes the procedures used to establish an Atlas of Strengths for this purpose. One sample was drawn from each of the male and female populations. Each sample consisted of 25 college students whose static and dynamic maximal strengths at five body joints were assessed. Measurements were taken using the Cybex II Isokinetic apparatus at three different speeds: 0 rpm (static), 5 rpm, and 25 rpm. At each speed, torque exertions began at different starting positions and covered a specified range of motion for dynamic measurements. Sagittal plane measurements were taken and measurements in other planes of motion at angles away from the sagittal plane were taken for some of the joints. The main results of this study are discussed.
