We postulated that primary motor cortex (M1) activity does not just decrease immediately prior to voluntary muscle relaxation; rather, it is dynamic and acts as an active cortical process. Thus we investigated the detailed time course of M1 excitability changes during muscle relaxation. Ten healthy participants performed a simple reaction time task. After the go signal, they rapidly terminated ...

This study aimed to analyze progressive muscle relaxation intervention as an alternative reduce symptoms in patients with chemotherapy. The method used is a systematic literature review through the Science Direct, Proquest, and Scopus databases. results of this indicate that 6 scientific articles obtained show can physical such pain fatigue psychological depression, stress, anxiety, drowsiness,...

Relaxation is the process by which, after contraction, the muscle actively returns to its initial conditions of length and load. In rhythmically active muscles such as diaphragm, relaxation is of physiological importance because diaphragm must return to a relatively constant resting position at the end of each contraction-relaxation cycle. Rapid and complete relaxation of the diaphragm is likel...

proprioceptive neuromuscular facilitation (pnf) training (contraction - relaxation method), in compared to the other methods of static and dynamic stretching exercises; has higher and safer effects on enhancement of hamstring muscle's flexibility, strength and endurance. achieving the optimal combination of contraction and stretching phases in pnf training that can increase these factors of phy...

The properties of relaxation, particular the sensitivity of relaxation to load, were analyzed in isolated intact atrial muscle and in manually dissected, detergent-treated cellular preparations from cat, dog, and rat atria. Force and length traces under increasing afterloads and following load clamps were obtained using an electromagnetic lever-force transducer system for the intact muscles and...

We have investigated the interactions between the cAMP and inositol 1,4,5-trisphosphate (IP3)-Ca2+ signalling systems in the bovine iris sphincter by measuring the effects of beta-adrenergic and cholinergic muscarinic agonists and antagonists on cAMP formation, IP3 accumulation and muscle contraction-relaxation. (1) Addition of 5 microM isoproterenol (ISO) or forskolin (5 microM) consistently p...
