GH administration, either alone or combined with resistance exercise training (RT), has attracted interest as a means of increasing muscle mass and strength in the elderly. In the present study, 31 healthy, elderly men [age, 74 +/- 1 yr (mean +/- SEM)] were assigned to either RT [3 sessions/wk, 3-5 sets of 8-12 repetition maximum (RM)/session] + placebo (n = 8), RT + GH (n = 8), GH (n = 8), or ...

Introduction Acute quadriceps tendon rupture is a relatively infrequent injury with serious consequences. The current gold standard for management of an acute quadriceps tendon rupture is surgical repair with suture through transosseous patellar bone tunnels. This repair has been successful, but can be a relatively time-consuming and labor intensive procedure, with potential complications inclu...

BACKGROUND although low strength is a risk factor for falls, lower limb explosive power is more predictive of functional difficulties than strength. Power may be more predictive of a future fall than strength per se. OBJECTIVE to compare leg muscle strength and explosive power and asymmetry of leg strength and power of women aged 65 or over living at home, with and without a history of falls....

BACKGROUND Loss of muscle strength as a result of normal aging is reported to impair functional ability in various communities. The purpose of this study was to determine the age at which loss of muscle strength and functional ability begins, and to establish a preliminary baseline for the pattern of changes in muscle strength and functional ability of aging in adult healthy Saudi Arabian males...

Purpose: Proprioception is a part of the somatosensory system responsible for sending information to the central nervous system to monitor the status of various body parts relative to each another. One of the main causes of impaired proprioception is fatigue. In the following study, the effects of fatigue on quadriceps muscle and hence on knee proprioception in healthy subjects was studied.&nbs...

The present study was designed to provide further insight into the neuromuscular mechanisms that determine the decrease in maximum strength and strength development of the quadriceps muscle with aging. Different neuromuscular tests were performed in order to assess the neural and muscular changes. The age-related decrease in isometric maximum voluntary torque (iMVT) was accompanied by a decline...

BACKGROUND Exercise programmes have shown to be important for the prevention of fractures in patients with established osteoporosis. However, few studies have evaluated the effect of such programmes for women with low bone mineral density (BMD) (osteoporosis or osteopenia) who have already suffered a fracture. Studies have indicated that exercise programmes concentrating on muscular strength an...
