Abstract : A simple ergometer has been designed and built which can be used to accurately stress divers in the various environments they normally encounter. The device is usable in both dry and wet environments including the open sea at all depths to which men have operated to date. It's size and weight make it easily portable and when the frame is partially disassembled it will fit through the vast majority of chamber hatches. The associated electronics and switching system virtually eliminate any ignition source that could cause a fire in an oxygen rich environment. The device has been used in a number of experiments by 9 subjects and has been readily accepted by them. A wide range of workloads are available ranging from 250 to 1400 kg-m/min. The design of the system minimizes the possibility of recording more work than the subject actually performs. The signalling/timing system provides a means of controlling the rate and duration of each work period from a remote location. (Author)
