Aim To analyze the lipid profile of older people aged ≥80 years according to body composition (high fat mass, low muscle mass and both). Material and method : The sample consisted of 113 older people aged ≥80 years. The assessment of body composition was made using Dual Energy X-ray Absorptiometry (DXA) and the lipid profile analysis using an enzymatic colorimetric kit. We used Analysis of Variance (ANOVA) test to compare the mean of lipid profile according to body composition and were constructed logistic regression models to verify the association between these two variables. Results It was found that older people with high fat had higher mean values of TG compared to normal and low muscle mass group. Older people with low muscle mass showed mean values of LDL-c lower than other groups. It was observed that older people with high fat is more likely to have (OR 2.70; 95%CI 1.14-6.37) high blood concentration of TG. Conclusion Thus, it appears that high fat is related to the high blood concentration of TG in older people aged ≥80 years, especially those with Asian origin and diabetes besides those with low muscle mass shows lower mean values of LDL-c.

The present study aimed to investigate the effects of traditional resistance training compared to elastic tubes training on bioimpedance vector patterns, body composition, and strength in older women. Thirty-eight older women (age 68.7 ± 6.9 years, body mass index 28.8 ± 7.2 kg/m2) were randomly assigned to perform traditional resistance or elastic tubes training three times per week for 12 weeks. Body composition was assessed by dual energy X-ray absorptiometry and bioelectrical impedance vector analysis. In addition, handgrip strength was measured using a dynamometer. Only the participants who followed the 12-week traditional resistance training program significantly (p < 0.05) decreased fat mass (ES: −0.69) and extracellular water (ES: −1.06), and increased total body water (ES: 0.49), intracellular water (ES: 1.11), body cell mass (ES: 0.82), muscle mass (ES: 0.94), and phase angle (ES: 0.99), while no change occurred in the elastic tubes training group. Furthermore, a vector leftward displacement (ES: 1.11) into the resistance-reactance graph was found only after the traditional resistance training program. The handgrip strength increased for both traditional and elastic tubes training groups (ES: 0.64, ES: 0.71, respectively). Traditional resistance training improved body composition and strength in the older women group, while training using elastic tubes was effective only for the latter. The present outcomes encourage the use of systematic resistance training to counteract the effects of aging in older women. • Resistance training with weight machines may be a potent stimulus to improve bioimpedance vector patterns and handgrip strength in older women. • Elastic tubes training offers a potential means for improving handgrip strength. • Training using elastic tubes may maintain but not improve body composition in older women.

Alterations in bioimpedance parameters and postural control occur with aging and contribute to the increased risk of falls. The aim of this study was to evaluate the balance behavior in relation to bioimpedance and functionality. We evaluated 21 elderly (men: 77.3 ± 9.5 years; women: 74.2 ± 9.6 years). The balance in standing posture was measured by the movement of the pressure center in seven positions. Bioimpedance was defined by its parameters resistance, reactance and phase angle, and functionality through the Timed Up and Go Test and Short Physical Performance Battery. In the analysis of the mediolateral velocity at the positions feet separated with open and closed eyes, feet together with eyes closed and semi-tandem with eyes open on the platform, an inverse correlation between balance and bioimpedance variables were verified for all models, with a coefficient of determination varying between 20% and 74%. Inverse and significant correlations between reactance and phase angle in the one-legged-support position were verified, in all adjustment models, with coefficient of determination varying between 62% and 91%. In the analysis of mediolateral velocity for the semi-tandem eyes closed position, positive correlation with TUG and an inverse correlation with bioimpedance parameters and pennation angle were observed, with coefficient of determination varying between 21% and 67%. The postural control is linearly related to bioimpedance parameters and functionality in the elderly. The assessment of balance can provide important information and furnishes useful insights for prevention and treatment strategies in elderly. • There is a correlation between postural control and bioelectrical variables. • Balance assessment can provide important information for treatment strategies in the elderly. • Bioimpedance assessment can be a reasonable alternative for balance evaluation in the elderly.

• Traditional resistance training and elastic resistance training are equally beneficial for the elderly. • Resistance training improved muscle strength, coordination, mobility and lipid profile in elderly. • Resistance training was unable to promote effects on inflammatory profile.
