Motor unit recruitment as reflected by muscle fibre glycogen loss in a prosimian (bushbaby) after running and jumping.
نویسندگان
چکیده
A qualitative histochemical assessment of glycogen loss in biopsies was made in bush-babies after running and jumping. Glycogen loss was related to the specific type of exercise. After running, glycogen loss was greatest in the slow-twitch oxidative fibre and depletion in the fast-twitch oxidative glycolytic fibres was similarly greater than in the fast-twitch glycolytic fibres. After jumping, the opposite pattern of glycogen utilization occurred (FG>FOG>SO).

Motor unit recruitment patterns 2: the influence of myoelectric intensity and muscle fascicle strain rate.
To effectively meet the force requirements of a given movement an appropriate number and combination of motor units must be recruited between and within muscles. Orderly recruitment of motor units has been shown to occur in a wide range of skeletal muscles, however, alternative strategies do occur. Faster motor units are better suited to developing force rapidly, and produce higher mechanical p...

متن کاملMotor units are recruited in a task-dependent fashion during locomotion.
Muscle fibres have a range of contractile properties from fast to slow. Traditional understanding of muscle fibre recruitment suggests that the slower fibres within a mixed muscle are used for all contractions including those at rapid speeds. However, mechanical arguments predict that some locomotor tasks are best performed by solely the faster fibres. Motor recruitment patterns can be indicate...
متن کاملThe effect of lower limb massage on EMG and force production of the knee extensors Running Head: Neuromuscular recruitment and force production of massaged skeletal muscle
Objectives: This study evaluated the effect of massage on force production and neuromuscular recruitment. Methods: Ten healthy male subjects performed isokinetic concentric contractions on the knee extensors at speeds of 60, 120, 180 and 240o.s. These contractions were performed before and after a 30 minute intervention of either rest in the supine position or lower limb massage. Electromyograp...
متن کاملDetermining patterns of motor recruitment during locomotion.
Motor units are the functional units of muscle contraction in vertebrates. Each motor unit comprises muscle fibres of a particular fibre type and can be considered as fast or slow depending on its fibre-type composition. Motor units are typically recruited in a set order, from slow to fast, in response to the force requirements from the muscle. The anatomical separation of fast and slow muscle ...
