Abstract : The work output characteristics of divers were tested during the performance of manual tasks which generally fell into three classifications: (1) A complex maintenance task involving the disassembly and reassembly of a water filtration unit. (2) A simple repetitive rotary task requiring continuous torque production against known resistances. (3) A simple repetitive discontinuous flexion/extension task requiring the exertion of linear forces against known resistances. During the task execution, heart rate and three skin temperatures were continuously monitored and electronically recorded. The underwater results were compared with performance values obtained from these tasks executed in normally tractive 'dry' environments and the observed decrements discussed in terms of biomechanical considerations and certain water effects.
