INTRODUCTION: The elderly population (EP) worldwide represents important challenges in public health policies. Chile is no exception with its exponential population growth. Chronic non-communicable diseases are the pandemic of the 21st century and strongly affect this population, losing years of healthy life. The EP in Chile has a 73.3% prevalence of suspected arterial hypertension (HTA), with only 60% aware of the condition and in treatment (DIPRECE, MINSAL). Regarding Diabetes Mellitus type 2 (DM2), 31% of EP have diabetes with low percentages of control of the pathology (SOCHED). For them, it is of great relevance to study these pathologies and how they may affect the performance of functional tests and heart rate variability (HRV) in institutionalized older women METHODS: 91 older women who met the eligibility criteria participated on this study. Fall risk tests were measured (dynamometry, arm curl, single leg balance test, timed up and go -TUG-, quadrant test and sit to stand 30 seconds), as well as HRV at rest for 5 minutes. The sample was grouped into EP with DM2 and HTA, this was statistically analyzed with JAMOVI software and ANOVA of one-factor was used. RESULTS: The tests that assess the risk of falls in institutionalized EP behave differently depending on the presence of DM2 or HTA, the median age of the observed population was 87 years (range 68-97). The prevalence of HTA 68% and DM2 was 20%. There was a lower performance in the different tests of risk of falls in people with DM2 in the hand dynamometry test (p = 0.01), as well as in the measurement of HRV, we observed lower values in pNN50 (p = 0.043) and pLF (p = 0.044). In EP with HTA we observed lower values in the different tests of risk of falls, dynamometry (p = 0.002), arm curl (p = 0.017), right and left one leg balance test (p = 0.020 and p = 0.028 respectively) and TUG (p = 0.004). CONCLUSION: We can conclude that there are significant differences between the behavior of the tests of risk of falls in older adult women when they present HTA and DM2, we also observe that in HTA the indexes of the HVR are affected, while in EP with DM2 the tests of risk of falls are mainly affected, the common point is that in both pathologies the performance of the hand dynamometry is affected. It can be proposed the utility of a battery of test of application in institutionalized women to assess the follow-up of these health conditions.

INTRODUCTION: Elastic band strength training has been proved to enhance myriads of fitness attributes in elderly cohort (1). However, effects of training frequency on fitness outcomes are less investigated, producing general recommendation that 2 to 3 resistance training per week provides the optimal stimulus for fitness improvements (2). Therefore, we aimed to explore effects of 2 vs 3 elastic band training sessions per week on functional fitness in older woman. METHODS: Eighty-two women were allocated randomly to an 2 sessions/week (2SW, n = 41, 75,7 ± 8,9 years, 70,8 ± 12,3kg) or a 3 sessions/week group (3SW, n = 41, 74,5 ± 8,2 years, 72,3 ± 11,6 kg). Resistance training protocol consisted of equal volume, chair-based, low- load whole-body resistance exercises (2 sets, 12-15 repetitions, 40-60% of one repetition maximum-1RM) using an elastic band, for 12 weeks. Functional fitness (30-s Chair Stand,30-s Arm Curl, 2-min Step Test, Chair Sit-and-Reach, Back Scratch, 8-Foot Up-and- Go, Handgrip Strength) were measured before and after the training period. A 2x2 repeated measures ANOVA was utilized to identify pre/post intervention changes and differences between groups. RESULTS: At baseline, no statistically significant differences were found between 2SW and 3SW groups (p > 0.05). The participants adherence to training sessions of over 90% was reported. Both groups exhibited a statistically significant improvements over time for the following variables: 30-s Chair stand, Arm Curl, 2-min step test, Back Scratch, 8-Foot Up-and- Go and Handgrip Strength. Chair sit -and-reach improved in 2SW only. Furthermore, statistically significant interactions for time*group were found for the Handgrip strength (before = 39.6 ± 12.1 kg and after = 42.4 ± 12.5 kg compared to before = 28.2 ± 14.4 kg and after = 36.0 ± 15.6 kg for 2SW and 3SW, respectively, p < 0.05). CONCLUSION: Implementing 2 or 3 elastic band training sessions per week over a duration of 12 weeks resulted in functional fitness benefits in elderly women that were comparable, in addition to improvements in handgrip strength. Therefore, both training approaches can be recommended for this particular population.

INTRODUCTION: The fear of falling (FOF) is associated with frailty among older adults [1]. As the early stage of frailty, prefrailty is more reversible and regarded as a key focus in frailty prevention [2]. However, whether FOF is associated with prefrailty and whether this association differs by gender remain unclear. Therefore, this study aimed to examine the association between FOF and prefrailty among community-dwelling older adults by gender. METHODS: This cross-sectional study included 489 community-dwelling older Japanese adults aged 65 years or older (132 men, mean age: 75.9 ± 5.3 years; 357 women, mean age: 73.9 ± 4.8 years). Assessments included anthropometric measurements (height, weight, BMI), physical function tests (grip strength and gait speed), and questionnaires. FOF was assessed using the Short Falls Efficacy Scale-International (Short FES-I), and prefrailty was assessed using the Japanese version of the Cardiovascular Health Study (J-CHS) criteria. All statistical analyses were conducted separately for men and women. Comparisons were made between the prefrailty and robust groups, and binary logistic regression analyses were used to examine the associations between prefrailty status (dependent variable) and age, BMI, grip strength, gait speed, and Short FES-I (independent variables). Furthermore, for variables that showed significant associations, receiver operating characteristic (ROC) analyses were performed to assess their discriminatory ability in identifying prefrailty. RESULTS: In men, Short FES-I scores did not significantly differ between the prefrailty and robust groups (p = 0.273), and binary logistic regression analysis showed no significant association between Short FES-I and prefrailty (OR: 1.04; 95% CI: 0.92–1.18; p = 0.494). In contrast, women in the prefrailty group had significantly higher Short FES-I scores than those in the robust group (p < 0.001). Binary logistic regression analysis showed a significant association between Short FES-I and prefrailty (OR: 1.13; 95% CI: 1.05–1.22; p < 0.001). Furthermore, ROC analysis indicated that in women, the area under the curve (AUC) for the Short FES-I was 0.647 (p < 0.001), with an optimal cutoff value of 12 points for identifying prefrailty (sensitivity, 0.56; specificity, 0.69). CONCLUSION: This study examined the association between FOF, assessed using the Short FES-I, and prefrailty in community-dwelling older adults. A significant association was observed only in older women, whereas no such association was found in men. This may be attributed to men having lower FOF levels than women, which could influence the association between FOF and prefrailty. These findings suggest that the association between FOF and prefrailty may differ by gender. References: 1. de Souza LF, et al. Clin Interv Aging. 2022. 17: 129-140. 2. Kojima G, et al.
