Physical Fitness, Body Composition and Frailty in Elderly People.Exercise Program Effecsts. EXERNET Elder 3.0

One of the major changes occurring in developed societies is a significant ageing of the population. Nowadays, because of an enhanced life expectancy, 17% of the Spanish population is composed of people over 65 and the number is expected to rise to 33% in 2050. Aging is characterized by a gradual lifelong accumulation of molecular and cellular damage that results in a progressive and generalized impairment in several bodily functions, an increased vulnerability to environmental challenges and a growing risk of disease and risk of death. These facts led to an increase on the prevalence of diseases such as osteoporosis diabetes, sarcopenia, obesity or frailty. However, lifestyles such as physical activity could attenuated aging process, maintaining the autonomy of elders, and it has been demonstrated that even implying guided exercise programs could reverse this condition of frailty and dependence. In this way, the main aims of this research project are to analyze the effect of a multicomponent exercise program in frailty and pre-frailty people above 65 years and without cognitive impairment. Thus, it is going to be evaluated at the beginning and the end of the study; body composition, physical fitness, blood parameters including vitamin D and other health related parameters included in a questionnaire. Secondly, to study the perdurability of training-related gains over time.
