Muscle has conventionally been viewed as a motor that converts chemical to kinetic energy
in series with a passive spring, but new insights emerge when muscle is viewed as a …

Science and Practice of Strength Training is a favorite book among strength and
conditioning professionals. Now in a third edition, it offers upgraded artwork, updates based …

An eccentrically lengthening, energy-absorbing, brake-driven model of hamstring function
during the late-swing phase of sprinting has been widely touted within the existing literature …

The peculiar attributes of muscles that are stretched when active have been noted for nearly
a century. Understandably, the focus of muscle physiology has been primarily on shortening …

Gaps in our understanding of muscle mechanics demonstrate that the current model is
incomplete. Increasingly, it appears that a role for titin in active muscle contraction might …

The active isometric force produced by muscles varies with muscle length in accordance
with the force–length relationship. Compared with isometric contractions at the same final …

Since its belated discovery, our understanding of the giant protein titin has grown
exponentially from its humble beginning as a sarcomeric scaffold to recent recognition of its …

The work loop technique has provided key insights into in vivo muscle work and power
during steady locomotion. However, for many animals and muscles, ex vivo experiments are …

Stretch–shortening cycles (SSCs) involve muscle lengthening (eccentric contractions)
instantly followed by shortening (concentric contractions). This combination enhances force …

The sliding filament–swinging cross bridge theory of skeletal muscle contraction provides a
reasonable description of muscle properties during isometric contractions at or near …
