Body Composition Characteristics of Community-Dwelling Older Adults With Dynapenia

Abstract: This study aimed to determine the differences in muscle and fat masses of the arm and leg between older adults with dynapenia, sarcopenia, or presarcopenia and normal individuals. The percent body fat, lean body mass, and skeletal mass index were measured with bioelectrical impedance analysis. Muscle function was evaluated using grip strength and walking speed. Participants were classified into four categories. Dynapenia was defined as low muscle function with normal muscle mass. Sarcopenia was defined as the … Show more

“…Musculoskeletal aging begins in midlife [ 1 ] and results in impaired neuromuscular strength in older adults [ 2 ]. The prevalence of obesity also increases with aging because of fat accumulation and muscle mass loss [ 3 , 4 ]. Thus an emerging term indicating the co-occurrence of low muscle strength and obesity, namely “dynapenic obesity”, was raised [ 5 ].…”

“…Достигнутый консенсус в их трактовке позволяет с высокой степенью достоверности диагностировать конкретный тип изменения структурно-функциональных характеристик поперечнополосатой скелетной мышечной ткани, возникающий на определенных стадиях развития инволюционного патологического процесса. Используемые врачом на амбулаторном приеме и в стационаре методы исследования (измерение средней трети окружности сегмента конечности, окружности талии, толщины кожно-жировой складки, динамометрия, УЗИ, КТ) весьма чувствительны и информативны, чтобы заподозрить или констатировать наличие у пациента субклинических и клинических форм возрастной патологии скелетных мышц -динапении, миопении, миостеатоза, пресаркопении, саркопении [18][19][20].…”

“…Снижение силы происходит со скоростью 3-4 % у мужчин, у женщин -2,5-3,0 % в год (в 2-5 раз быстрее потери мышечной массы) [5,6]. У пожилых женщин снижение касается не только мышечной, но и костной массы [20].…”
