Background  Previous studies have just found skeletal muscle mass decline is associated with arterial stiffness, but it is unclear whether muscle strength and physical performance as important compositions of sarcopenia are associated with arterial stiffness. The aim of this study was to investigate the relationship between sarcopenia, the components of sarcopenia and arterial stiffness among elderly in the community.    Methods  This study enrolled 450 elderly people who received general medical examinations in Tianjin First Center Hospital. Each of the subjects was greater than 65 years old, including 266 male and 184 female subjects. Based on the diagnostic criteria for sarcopenia in older people developed by the Asian Working Group for Sarcopenia (AWGS), 89 subjects were separated into the sarcopenia group. The living habits, disease status, general status and laboratory examinations of all subjects were collected. The body composition (including appendicular skeletal muscle mass and visceral fat area (VFA) of each participant) was measured by bioimpedance analysis. HS, usual gait speed (GS), and brachial ankle pulse wave velocity (baPWV) were measured.    Results  Sarcopenia subjects had higher baPWV, nutrition risk and lower appendicular skeletal muscle index (ASMI), Handgrip strength (HS), GS, body mass index (BMI), triacylglycerol (TG), serum albumin (ALB) and creatinine (Cr) than did non-sarcopenia subjects; Sarcopenia subjects also had higher visceral fat area (VFA) than did non-sarcopenia subjects ( p  < 0.05). ASMI and HS were negatively associated with baPWV (t = − 5.807,  p  = 0.000 and t = − 3.085,  p  = 0.002), but the relationship between baPWV and GS was not statistically significant (t = − 0.862,  p  = 0.389) by multivariable linear regression. After adjusting for confounders, a multivariate logistic regression analysis revealed that sarcopenia was related with age, BMI, sports and baPWV in community dwelling elderly.    Conclusions  ASMI and HS were negatively associated with baPWV in community dwelling elderly in China; and baPWV was a risk factor of sarcopenia.
