Some parameters used to diagnose sarcopenia, and functional autonomy disorders can lead to interpretation and classification errors.Objective: to analyze sarcopenia markers and their relationship with the strength and gait of physically active older women aged between 55 and 76 years.Materials & Methods: Analytical observational study conducted in 178 physically active Colombian women who were distributed in two age groups (Group 1: 55-66 years, n=98, and Group 2: 67-76 years, n=80). A multiple linear regression model was used to establish possible correlations between strength and gait indicators (dependent variables) and body composition (independent variables).Results: In group 1 (G1) the fat mass and the appendicular mass (appendicular lean/height2(kg/m2)) explained the variance of the power in the lower limbs (SJ: p= 0.001, R2 =0.56; CMJ: p =0.001, R2 =0.51; CMJAS: R2 =0.60, P= 0.001). Similar results were observed in group 2 (G2) (SJ: R2=0.32, DW=2.14; CMJ: R2 = 0.51, DW=2.38; CMJAS: R2=0.41, DW=2.56). Furthermore, fat mass explained differently the variance in G1 and G2 regarding the gait pattern (G1: p=-0.006; R2=20%; G2: p =-0.001; R2=29%). Conclusion: The records of fat and appendicular mass allow studying negative changes in lower limb strength, and their effect on the gait pattern, as well as identifying the type of sarcopenia and functional autonomy disorders in Colombian physically active Colombian women aged 55 to 76 years.
