Advancing eon in men may result in change magnitude blood serum levels of both androgens (i.e. testosterone) and proceeds hormone. While the physiologic features of senescence ar certainly of intrinsic interest, they only when achieve clinical greatness when some bodily function undergoes alteration. Clearly, there are operational consequences to the changes which occur in body composition, bone mass, and muscle effectualness among aged men. One general compositional trend, for instance, consists of a modernized decrease in lean body mass. This contraction reflects atrophic developments of skeletal muscle, liver, kidney, spleen, skin, and bone (15:1-5). In addition to decreased strength, the conglome roll other associated physiological effects include the following: (1) decreased renal blood flow and diminished glomerular filtration rate; and (2) increased adiposity with concomitant adverse effects on blood pressure, glucose clearance, and plasma lipoprotein profiles (14:73-74).

More all over, one of the most significant causes of unwholesomeness and mortality among the elderly consists of osteoporotic sunder. While osteoporosis among men has received little attention than osteoporosis in women, the male disease is in any case an consequential public health problem (11:133-134). Murphy et al. (1993) estimates that the probability of a man experiencing a broken hip by age 85 year is nearly 5 percent. Further, the age-specific hip fracture incidence rates book more than doubled over the past several decades.

Likewise, the physiological interaction between harvesting hormone and exercise is also complex. H?kkinen et al. (1985) found that after 24 weeks of physical exercise, subjects' humble GH levels remained unaltered (3:166). Moreover, Pyka et al. (1992) found that, although resistance exercise acutely touch on GH secretion in young people, the response in elderly men was "profoundly depressed (18:1361)."

The various changes which result from growth hormone deficiency are similar to those observed in senescence.

In such organs as the skin, muscles, kidneys, liver, and digestive tract, GH acts through insulin-like growth factor-I (IGF-I) to stimulate amino acid uptake. This uptake enhances the price reduction of numerous bioactive compounds (e.g. deoxyribonucleic acid, proteins, mucopolysaccharides, etc.), and ultimately promotes both cell division and growth. In addition, another action of GH involves the adipocytes. Under normal conditions, GH is constantly contend the action of insulin on adipocytes. In doing so, the hormone not only restrains lipogenesis, it also promotes intracellular lipolysis. Overall, the hormonal action affects the entire being: It achieves a somatotropic effect by "shrinking the adipose organ, glowering the respiratory quotient, and diverting metabolic fuel from adipose create from raw material to the LBM (14:75)."

Obviously, more research is needed to delineate the various mechanisms whereby testosterone, growth hormone, and exercise interact to modulate age-related physiological declines. The elderly jibe a heterogenous population. This fact complicates most analyses and makes broad induction difficult. However, large prospective studies might be able to actualize the beneficial effects of hormonal replacement therapies. Once these benefits have been clearly defined, they can then be compared to the treatmen
