Abstract:

The purpose of the study was to investigate the effect on physiological functions of doing static work while maintaining constant shoulder torques in a midsagittal plane. The torques were applied by statically resisting a weighted lever arm. Each level of torque was held constant while the angle of elbow flexion and the height of the shoulder below the lever arm were varied. It was concluded that the best elbow flexion angle for static lever work is in the vicinity of 100 degrees, with the best working shoulder height between 10 to 15 inches below the point of application of force. It was further concluded that 100 degrees of elbow flexion allows almost steady state of ventilation rate over the entire work period for all loads. These conclusions were based on the population used and within the limits of the investigation.
