Animal data on muscle energetics should not yet influence clinical practice; leaves open mechanistic insights for cardiac muscle research.
Tortoise skeletal muscle demonstrates greater efficiency in converting free energy into work compared to frog muscle, associated with distinct force-velocity and heat production characteristics.
R. C. Woledge (1968) studied Tortoise skeletal muscle physiology. Tortoise skeletal muscle vs. Frog muscle was evaluated on Mechanical behaviour and heat production during tetanic contractions. Tortoise skeletal muscle demonstrated greater efficiency than frog muscle at converting free energy into work, with a lower maintenance heat rate and shortening heat constant.
