Abstract:
The purpose of this study was to ascertain if a relationship existed between plasma somatomedin C (SmC) level, as an indicator of growth hormone secretion, and muscle performance. Eighteen community-dwelling men between the ages of 65 and 80 comprised the sample group. Muscle strength, power and endurance were measured isokinetically on the elbow flexors and extensors and on the knee flexors and extensors. No relationship was found between plasma SmC levels and measures of muscle performance (P greater than 0.05). The limitations of this study as well as suggestions for future studies were discussed. Further research is needed to assess the effects of growth hormone on muscle performance.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
