Static lifting strengths of nine men and nine women were measured at six heights from just above the floor to just above the head, at two horizontal reaches from the mid-ankles (equal to the elbow to grip and acromium to grip distances), in the sagittal plane and also at 45 degrees and 90 degrees to the right for two-handed exertions and at 45 degrees and… (More)
PURPOSE A flywheel system of variable inertia is described for inferring the mechanical properties of human muscle during a single explosive movement. METHODS The system consists of a lightweight aluminum disk mounted on a shaft onto which a driving cog is mounted. The inertia of the system can be varied from 0.024 to 0.69 kg.m(2) by attaching… (More)
An economical method of recording peak pressures under the feet while standing or walking is described for clinical application. Normal values at 10 defined locations are presented. Correlation matrices indicate functional links between regions of support which influence patterns of deviation from the norms.
The power generated in single pulling movements in seated and standing postures was measured by means of novel dynamometers. The power available is strongly dependent upon the resistance to movement, as well as the posture. Some of the results have been applied to an assessment of the matching of outboard motors to their users, illustrating an ergonomic… (More)
