It’s not that humans are inherently slow; it’s just that ostriches are exceptionally skilled runners. They possess a unique combination of speed and efficiency in their gait that is unparalleled in the animal kingdom. Ostriches have the ability to store double the elastic energy per step in their tendons compared to humans. This efficient energy storage significantly reduces the effort required by their leg muscles to maintain high speeds.
In a study conducted by Rubenson et al. (2011), researchers examined the running mechanics of ostriches and humans to understand how ostriches achieve such remarkable running efficiency. Reflective markers were placed on the joints of both ostriches and human participants, who were recreational active males of similar weight. The study ensured that both groups ran at exactly the same average speed, enabling a fair comparison.
The researchers discovered that ostriches and humans expend almost the same amount of mechanical work to swing their limbs during running. However, the key difference lies in the storage and release of elastic energy by the tendons. Ostriches exhibited, on average, 83% greater storage and release of elastic energy, resulting in an astonishing 120% greater mechanical power generated through elastic recoil. Elastic recoil contributed to a significant portion (54.0 ± 0.1%) of the total positive mechanical work in ostriches, whereas it accounted for only 25 ± 6.3% in humans.
Furthermore, the estimated positive mechanical power of the muscle fibers during running was found to be 35% lower in ostriches compared to humans. In humans, the majority of positive mechanical work is produced by the hip joint, while in ostriches, the stance-phase mechanical work is primarily performed in the TMP joint, with the ankle joint playing a dominant role during limb swing.
These findings highlight the exceptional running capabilities of ostriches and the remarkable efficiency of their locomotion. Losing out to an ostrich in a running competition is nothing to be ashamed of, considering their unique physiological adaptations for speed and energy conservation.
