Human muscle undergoes constant changes. After about age 50, muscle mass decreases at an annual rate of 1-2 %. Muscle strength declines by 1.5 % between ages 50 and 60 and by 3 % thereafter. The reasons for these changes include denervation of motor units and a net conversion of fast type II muscle fibers into slow type I fibers with resulting loss in muscle power necessary for activities of da...

OBJECTIVES We investigated the associations of sarcopenia-defined both in terms of muscle mass and muscle strength-and sarcopenic obesity with metabolic syndrome. METHODS Secondary data pertaining to 309 subjects (85 men and 224 women) were collected from participants in exercise programs at a health center in a suburban area. Muscle mass was measured using bioelectrical impedance analysis, a...

BACKGROUND We evaluated the prevalence of sarcopenia, presarcopenia, and severe sarcopenia in healthy Korean elderly women. METHODS We measured the muscle mass and muscle function of 196 ambulatory women over the age of 65 years who visited the University Hospital Menopause Clinic. Appendicular skeletal muscle mass was measured by dual energy X-ray absorptiometry to measure skeletal muscle ma...

OBJECTIVE Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength, with the risk of frailty and poor quality of life. This study aimed to clarify the clinical characteristics of sarcopenia and to investigate the effects of comprehensive cardiac rehabilitation (CCR), including nutrition, physical exercise and medication, in patients with ca...

The relationship between PWCFT and common measures used to assess sarcopenia in older adults were examined. Fifty-eight older adults [age: 71.1 ± 6.2 years; body mass index (BMI): 28.0 ± 5.4 kg/m(2)] completed the testing procedures. Sarcopenia-related body composition was measured by dual-energy X-ray absorptiometry and participants performed a discontinuous cycle ergometry test to determine P...

BACKGROUND The aim of this study was to evaluate the factors associated with low skeletal muscle mass (SMM), sarcopenia, and sarcopenic obesity using nationally representative samples of people aged ≥65 years from diverse geographical regions of the world. METHODS Data were available for 18 363 people aged ≥65 years who participated in the Collaborative Research on Ageing in Europe survey con...

There is a progressive loss of muscle strength, muscle mass and muscle quality with advanced age, which results in a condition known as sarcopenia. In this review, the authors outline the magnitude of these losses, their functional consequences, and the efficacy of strength training (ST) as an intervention strategy for delaying, preventing or reversing the effects of sarcopenia. The question of...

PURPOSE OF REVIEW Highly prevalent in the population older than 65 years and leading to poor outcomes (functional decline and its related consequences), sarcopenia does not benefit yet either of a clear understanding of its pathophysiology or of precise clinical or biological markers allowing its identification. RECENT FINDINGS The new scientific definition of 'geriatric syndromes' challenges...

There has been increasing interest and research into sarcopenia in community-dwelling older adults since the European Working Group on Sarcopenia in Older People (EWGSOP) agreed a consensus definition in 2010. Sarcopenia has been defined as loss of muscle mass with loss of muscle function (strength or physical performance), with measurements two Standard Deviations (SDs) below the mean of a you...

OBJECTIVE To investigate the relationship between frailty and sarcopenia, by evaluating the prevalence of sarcopenia among frail, pre-frail and robust elderly nursing home residents in Belgium. METHODS This is an analysis of baseline data collected from the SENIOR (Sample of Elderly Nursing home Individuals: an Observational Research) cohort. All subjects received a sarcopenia evaluation, bas...
