TL;DR: Sarcopenia should be considered in all older patients who present with observed declines in physical function, strength, or overall health, and patients who meet these criteria should further undergo body composition assessment using dual energy x-ray absorptiometry with sarcopenia being defined using currently validated definitions.

TL;DR: Prevalence of sarcopenia is substantial in most geriatric settings, and well-designed, standardised studies evaluating exercise or nutrition interventions are needed before treatment guidelines can be developed.

TL;DR: It is suggested that a quantitative loss in muscle CSA is a major contributor to the decrease in muscle strength seen with advancing age and accounts for 90% of the variability in strength at T2.

TL;DR: The findings suggest mobility benefit from a structured, moderate-intensity physical activity program compared with a health education program reduced major mobility disability over 2.6 years among older adults at risk for disability.

TL;DR: It is concluded that "Sarcopenia, ie, reduced muscle mass, with limited mobility" should be considered an important clinical entity and that most older persons should be screened for this condition.
