Abstract
The aim of the project is to explain the marked increase in efficiency of running as body size increases in quadrupedal mammals. High speed video/cine, sonomicrometry and electromyography will be used to determine in vivo patterns of muscle strain and activity, at different running speeds, in mammals ranging in size from mice to rabbits. The in vivo operating conditions will be simulated in vitro using isolated muscle fibre preparations, with the work loop technique. Mechanical power output and heat production of both fast and slow muscle fibres will be measured under conditions simulating running at different speeds, to determine efficiency.
