I am fully aware of the distinction bestowed upon me to participate in tonight's meeting held to honour the memory of Sir Adolphe Abrahams. Sir Adolphe was the founder of clinical sports medicine and I for one am greatly indebted to him for much he taught me. No one before him has brought to bear upon the study of athletics the same combination of comprehensive knowledge of internal medicine an...

Most human beings experience peak physical performance in their late teens and begin a slow decline in their early 20s, whose course is greatly affected by the activity levels undertaken by individuals in the years that follow. Many studies provide evidence that in developed nations such as the U.S., a sedentary lifestyle contributes significantly to development of the major risk factors for ag...

PURPOSE Social theories of aging are discussed in relation to their preparedness to address the aging-with-physical impairment phenomenon. DESIGN AND METHODS An overview of the social theories of aging is presented. Individual theories of aging are reviewed to examine (a) how they currently depict and/or include disability in their frameworks and (b) how they could be used to explore the expe...

the internal structure of a molecule can be presented in terms of intra-molecular (i.e., inter atomic)and inter-molecular energies such as van der waals, bond and bending, torsion, and inversion energy.in this study, changes in molecular energies of individual asphalt components are evaluated as afunction of physical aging factors. the factors for physical aging such as temperature and pressure...

Lifetime physical inactivity interacts with secondary aging (i.e., aging caused by diseases and environmental factors) in three patterns of response. First, lifetime physical inactivity confers no apparent effects on a given set of physiological functions. Second, lifetime physical inactivity accelerates secondary aging (e.g., speeding the reduction in bone mineral density, maximal oxygen consu...
