Physiological adaptations to resistance exercise as a function of age

BACKGROUND The impact of resistance exercise training (RE-T) across the life span is poorly defined. METHODS To resolve this, we recruited three distinct age cohorts of young (18-28 years; n = 11), middle-aged (45-55 years; n = 20), and older (nonsarcopenic; 65-75 years; n = 17) individuals to a cross-sectional intervention study. All subjects participated in 20 weeks of fully supervised whol...

Physiological Changes in Teeth as a Tool to Estimate Age

With increasing age there are many changes in teeth such as attrition, peridontal disease, deposition of secondary dentine, root translucency, cementum apposition, root resorption, color changes, and increase in root roughness. By taking into consideration these secondary changes in teeth with advancing age, various studies were done to estimate the age of an individual. Such research has resul...
