In which variations in these reductions occur, where the staple fibres of type I more are preserved of what of type II. In way I specify staple fibres of slow contraction staple fibres type I, more are preserved during the aging process from there we can evaluate that in some cases the capacity of the aged ones to execute movements that demand speed they are compromised by the reduction more accented of staple fibres type II (KAUFFMAN, 2001). Still as she affirms Kauffman (2001, P. 9), Many morphologic properties, physiological biochemists and of the esqueltica musculatura are determined, or at least strong influenced, for the ratio and distribution of different types of fiber. Thus, a loss or a transformation of staple fibres can have a significant effect on the muscular function. The ocorrentes functional limitations in the musculoesqueltico system also are associates to the sarcopenia that according to Baumgartner (1998), defined that the sarcopenia could be defined as a reduction of the esqueltica muscular mass. But still based in the studies of Kauffman (2001), we cannot generalize that all the muscles are affected of similar form during the aging. The sarcopenia influences directly in the muscular mass of the aged one in the majority of the cases, but we must also take in consideration other actions as, the reduction in the alimentary ingestion that stops some authors is called ' ' anorexy of envelhecimento' '.
The reduction in the alimentary ingestion can be a contributing factor for the advance of the sarcopenia during the aging (HISSES; COLS, 2006). Other effect of the process of aging in this system, involve the sseos fabrics, joints the ligaments, that are basic elements together with the muscles for the accomplishment of the movements of the body, in such a way we will go to detach some related important aspects to the aging process. According to Kauffman (2001), the sseos fabrics supply sustentation to the body where they give form and they also assist in the corporal movement and in the protection of some agencies, being endowed with two determined categories, one for flat bones and another one for long bones.
