Background and Aim: With increasing age, the problems associated with decrease in muscle volume and strength, so-called sarcopenia increase as well. The purpose of this study was to investigate the relationship between muscle volume and strength and some of the factors associated with sarcopenia in the elderly compared with young people.

Materials and Methods: 24 old men aged 55 to 70 years and 20 young men aged 20 to 35 years participated in the study. Quadriceps Volume and cross-section area by CT imaging, strength by squats and leg extension were measured. Eventually, the Pearson correlation test was used to assess the correlation between variables.

Results: The result showed that muscle strength and volume in the elderly group is lower than younger group (p<0/05). Also a significant correlation was observed between strength and muscle volume in the elderly and young (p<0/05). The results also revealed a significant correlation between muscle volume and strength with age, aerobic and anaerobic capacity, quality of life, physical activity and balance in the elderly (p<0/05).

Conclusion: Muscle volume and strength is strongly associated with parameters related to sarcopenia. According to the decrease in muscle volume and strength in the elderly and its relationship with age, Preventive strategies against reduction in muscle volume and strength in elderly, seem to be necessary.
