The bipedal stance and gait of theropod dinosaurs evolved gradually along the lineage
leading to birds and at some point (s), flight evolved. How and when did these changes …

Although the cheetah is recognised as the fastest land animal, little is known about other
aspects of its notable athleticism, particularly when hunting in the wild. Here we describe …

Running speed is limited by a mechanical interaction between the stance and swing phases
of the stride. Here, we tested whether stance phase limitations are imposed by ground force …

The cheetah and racing greyhound are of a similar size and gross morphology and yet the
cheetah is able to achieve a far higher top speed. We compared the kinematics and kinetics …

Muscle mechanical output such as force and power are governed by highly nonlinear
intrinsic muscle properties associated with different muscle fiber types and are influenced by …

Flying birds often form flocks, with social, navigational and anti-predator implications.
Further, flying in a flock can result in aerodynamic benefits, thus reducing power …

Why is maximal running speed reduced on curved paths? The leading explanation
proposes that an increase in lateral ground reaction force necessitates a decrease in peak …

Running-specific prostheses (RSP) emulate the spring-like behaviour of biological limbs
during human running, but little research has examined the mechanical means by which …

Despite the cheetah being the fastest living land mammal, we know remarkably little about
how it attains such high top speeds (29 ms− 1). Here we aim to describe and quantify the …

This study investigated changes in performance and technique that occur during maximal
effort bend sprinting compared with straight-line sprinting under typical outdoor track …
