Moderate quality evidence suggests that exercise interventions improve muscle strength and physical performance. Sarcopenic obesity predicts instrumental activities of daily living disability in the elderly. In conclusion, a clinically more relevant approach to define sarcopenia should be based on cutoff points of muscle mass or muscle quality levels determined by expert consensus according to the risk for future health-related events, such as mortality, physical disability, or metabolic disorders.

Many explanations for sarcopenia have been proposed such as neurodegenerative process, reduction in anabolic hormone productions or sensitivity, dysregulation of cytokine secretions, modification in the inflammatory state Fig. Eur J Canc, 33pp. Age Ageing, 33pp. Abellan van Kan G. The aim of the present review is to summarize the main operational definitions of sarcopenia and describe the different methods assessing sarcopenia, together with results from Korean sarcopenic obesity study KSOS that we performed.

Am J Epidemiol Multiple levels of the nervous system are affected by age, including the motor cortex, the spinal sqrcopenia, peripheral neurons, and the neuromuscular junction. Authors further examined the association between MFR, components of metabolic syndrome, and arterial stiffness in an apparently healthy general population. A third approach to define sarcopenia is the use of residual method developed by Newman et al.

During slow, low intensity activity, most strength generated comes from type I fibers, while in high intensity exercise strength comes from type I and II fibers. In addition, many explanations for sarcopenia have been proposed metabolic effects such as reduction in anabolic hormone productions or sensitivity, dysregulation of cytokine secretions, and inflammatory state.
