Multi-station equipment for physical training: design and validation of a prototype.

The design of a prototype multi-station exercise machine is described. Resistance models and muscle groups used varied between stations which were constructed to accommodate a wide range of individual differences. The apparatus was validated using time-motion analysis, anthropometry, subjective user responses and physiological methods. Problems at the man-machine interface were identified, and risk and discomfort factors minimised. The equipment is recommended for use both to athletes for specific conditioning and to recreational users for endurance and strength training.
