The size and arrangement of fibres play a determinate role in the kinetic and energetic
performance of muscles. Extrapolations between fibre architecture and performance …

This review examines literature that used physiological cross‐sectional area (PCSA) as a
representative measure of an individual muscle's maximal isometric force production. PCSA …

The tradeoff between force and velocity in skeletal muscle is a fundamental constraint on
vertebrate musculoskeletal design (form: function relationships). Understanding how and …

Skeletal muscle mass, architecture and force-generating capacity are well known to scale
with body size in animals, both throughout ontogeny and across species. Investigations of …

Tree sloths have reduced skeletal muscle mass, and yet they are able to perform
suspensory behaviors that require both strength and fatigue resistance to suspend their …

Prehension involves the ability to reach, grasp and transport an object. It is a fitness-relevant
behaviour with an important role in food acquisition and locomotion. Grasping an item …

The nine-banded armadillo, Dasypus novemcinctus, is a member of the family Dasypodidae,
which contains all extant species of armadillos and represents the most diverse group of …

Humboldt's woolly monkey (Lagothrix lagortricha) is a ceboid primate that more frequently
engages in plantigrade quadrupedalism (~ 89%) but is, like most other members of the …

Sloths exhibit almost obligatory suspensory locomotion and posture. These behaviors
require both strength and fatigue resistance, although we previously found muscle fiber type …

The scratch‐digging Cape dune mole‐rat (Bathyergus suillus), and the chisel‐toothed
digging naked mole‐rat (Heterocephalus glaber) are African mole‐rats that differ in their …
