2009 Available online 31 October 2009 Keywords: Aging Force–velocity Muscles Strength Power a b s t r a c t Aging in humans is associated with a loss in neuromuscular function and performance. This is related‚ in part‚ to the reduction in muscular strength and power caused by a loss of skeletal muscle mass (sarcopenia) and changes in muscle architecture. Due to these changes‚ the force–velocity (f–v) relationship of human muscles alters with age. This change has functional implications such

Written Report: Prolonged Immobilization I. A. Definition Defined as prolonged inactivity‚ bed rest and immobilization were widely used in the early days of rehabilitative science in the management of trauma and acute and chronic illness‚ before the physiologic effects were well understood. It was generally assumed that rest fostered healing of the affected part of the body. However‚ while it has beneficial effects to soft tissue healing and to bone healing after fractures among a myriad of other

Neuromuscular blocking drugs were first used by South American Indians on their arrows to paralyze their prey. During that time neuromuscular drugs were called curare. They were first written about in a letter by a chronicler‚ employed by the Court of King Ferdinand and Queen Isabella‚ in 1516. In the 18th century Edward Bancroft‚ a physician‚ brought samples of curare back from South America and Sir Benjamin Brodie showed how small animals could be left alive after being injected with curare and

In the case of muscle ‚the stimulus is usually a chemical for example - a neurotransmitter released by a nerve cell‚ or a local change in ph. The response is generation of of an electrical impulse that passes along the sarcolemma of the
