Research overview: elastic energy storage in cheetah tendons

Elastic tendons can store and return energy like springs, reducing the muscular cost of each stride. This overview reviews evidence for and against substantial elastic energy storage in the cheetah hindlimb compared with specialists such as kangaroos or hopping antelope. Cheetahs prioritise acceleration and power over economical steady-state running, so their muscle-tendon architecture may favour rapid force production with relatively muscular, less spring-like properties. Researchers estimate tendon contributions from cross-sectional area, material stiffness, and muscle fascicle geometry obtained by dissection and imaging. The comparison clarifies why the cheetah build differs from that of endurance cursors and why its locomotor strategy centres on short, intense bursts rather than economical distance running, with implications for how we interpret its limb anatomy.
