Background: Limb muscle dysfunction is prevalent in chronic obstructive pulmonary disease
(COPD) and it has important clinical implications, such as reduced exercise tolerance …

Biopsies have been acquired from living men and women to determine proportions of Type I
(slow‐twitch) and II (fast‐twitch) skeletal muscle fibers since the 1970s. Sex differences have …

Understanding of biomechanical factors in sprint running is useful because of their critical
value to performance. Some variables measured in distance running are also important in …

Fatigue is defined as a failure to maintain the required or expected force. The force of a
voluntary contraction is graded according to both the tension generated in each muscle fibre …

Insight into the magnitude of muscle forces is important in biomechanics research, for
example because muscle forces are the main determinants of joint loading. Unfortunately …

1. We have investigated the possibility that voluntary muscle lengthening contractions can
be performed by selective recruitment of fast‐twitch motor units, accompanied by …

It has been proposed that the invariant kinematics observed during goal-directed
movements result from reducing the consequences of signal-dependent noise (SDN) on …

Experiments were designed to assess the relative contribution of rate coding and motor unit
recruitment to force production in two muscles of different fiber composition and function …

Soon after Edward Liddell [1895–1981] and Charles Sherrington [1857–1952] introduced
the concept of a motor unit in 1925 and the necessary technology was developed, the …
