Introduction: Anthropometry and functional fitness (FF) are fundamental aspects for functional independence conservation of older adults (OA). However, little has been investigated in chilean OA. Objective: To analyze anthropometric and FF characteristics of non-disabled OA. Methods: One hundred and sixteen subjects participated in the study. It was determined the prevalence of weight categories (Body Mass Index [BMI]) and cardiometabolic risk (CMR) (Waist Circumference [WC], Waist-Hip Ratio [WHR] and Waist-to-Height ratio [WHtR]). Additionally, "under the norm" physical performance and performance standards (Senior Fitness Test Battery [SFT]). Anthropometric and FF differences were analyzed according sex and age categories. Results: A total of 63.8% and 73.5% of men and women respectively were overweight. The highest prevalence of CMR was obtained through WHtR and the tests with the highest prevalence of low performance were 2-minute step Test and Back scratch Test. The performance standard was reached in 29.7% and 17.3%, in men and women respectively. Men presented greater height, WHR, strength and aerobic capacity. Women had greater hip circumference, BMI, WHtR and flexibility. These results tends to be maintained in the analyzes according age categories. Conclusions: The studied sample presented a high prevalence of overweight, CMR and low physical performance especially in women. Due its low cost and complexity, it is proposed that integral evaluation of anthropometric and FF parameters should be implemented in primary care programs aimed to preserving functionality of OA.

Background: There is no conclusive evidence about the association between physical fitness (PF) and health related quality of life (HRQOL) in older adults. Aim: To seek for an association between PF and HRQOL in non-disabled community-dwelling Chilean older adults. Material and Methods: One hundred and sixteen subjects participated in the study. PF was assessed using the Senior Fitness Test (SFT) and hand grip strength (HGS). HRQOL was assessed using eight dimensions provided by the SF-12v2 questionnaire. Binary multivariate logistic regression models were carried out considering the potential influence of confounder variables. Results: Non-adjusted models, indicated that subjects with better performance in arm curl test (ACT) were more likely to score higher on vitality dimension (OR > 1) and those with higher HGS were more likely to score higher on physical functioning, bodily pain, vitality and mental health (OR > 1). The adjusted models consistently showed that ACT and HGS predicted a favorable perception of vitality and mental health dimensions respectively (OR > 1). Conclusions: HGS and ACT have a predictive value for certain dimensions of HRQOL.

Introduction: the regular practice of physical exercise is an important modulator of resting energy expenditure (REE), which depending on the intensity, duration, and type of exercise can increase the REE in an acute manner as well as long term. The effects of dynamic muscular strength exercises on the REE have been treated very little in literature. Objective: compare the effect of muscle strength exercise (MSE) at different intensities on the REE in young males. Methods: Intra-group design. Fourteen subjects aged 22,5±1,5 0,05) after the exercise at 40%RM. The REEpost 24h was maintained according to the REEpre when the intensity was 80%RM. Conclusion: The REEpost exercise is independent of the intensity of the exercise and only is maintained after 24 hours when the MSE is at a high intensity
