Fruit and vegetable intake, physical activity, and functional fitness among older adults in urban Alaska.

Older adults often face barriers to obtaining recommended diet, physical activity, and fitness levels. Understanding these patterns can inform effective interventions targeting health beliefs and behavior. This cross-sectional study included a multicultural sample of 58 older adults (aged 55+ years, M=71.98) living in independent senior housing in urban Southcentral Alaska. Participants completed a questionnaire and the Senior Fitness Test that assessed self-reported fruit and vegetable intake, physical activity, self-efficacy, and functional fitness. T-tests and bivariate correlation analyses were used to test six hypotheses. Results indicated that participants had low physical activity but had a mean fruit and vegetable intake that was statistically significantly higher than the hypothesized "low" score. Only 4.26% of participants met functional fitness standards for balance/agility, and 8.51% met standards for lower-body strength. However, 51.1% met standards for upper-body strength and 46.8% met standards for endurance The results also indicated that nutrition self-efficacy and exercise self-efficacy were positively related to fruit and vegetable intake and physical activity levels, respectively. Interestingly, income was not related to nutrition or activity patterns. These data complicate the picture on dietary and physical activity patterns for older adults in Alaska and offer recommendations for future health promotion activities.

Functional fitness benchmark values for older adults: a systematic review.

Introduction: The use of normative values and/or standards of functional fitness in adults is relevant to overall health and well-being. The objectives of the study were: to identify the physical tests of the senior fitness test (SFT) that have been applied since its proposal and to describe the proposed percentiles according to age, sex and country. Methods: A systematic review study was conducted in the Pubmed and Scopus databases. As eligibility criteria, we considered the period from 1999 to 2022 that presented data on SFT test used in the population over 60 years of age and that described normative values through percentiles. MeSH were used as: (1) Physical fitness, Exercise test, Senior Fitness Test, Functional fitness, Cardiorespiratory fitness, (2) older adult, aged, (3) Reference standards, standards, standards of care. Boolean operators "AND" and "OR" were included. Data extracted from the selected studies included: year of publication, country, sample age, sample size, sample sex, fitness component. Results and discussion: Seven studies were identified in five countries (03 in China, 01 in Poland, 01 in Portugal, 01 in Spain and 01 in United States). The age range ranged from 60 to 103 years. The studies were conducted in both sexes. The study with the smallest sample size was by Chung et al. (China) with 944 participants and the largest number of participants was the study by Rikli and Jones in the United States with 7,183 participants. In general, no study was able to complete 100% (8 components) of the tests proposed in the SFT. Normative values were presented through percentile distribution (p10, p50 and p90) organized by age ranges. Males presented better performance in FPF tests than females in all tests. Since the first publication of the SFT until 2022, seven articles have been published in countries such as United States, China (three regional studies), Poland, Portugal and Spain. No study has published the complete battery with its eight components. The percentiles of functional fitness reflect decline with advancing age.

Brisk walking improves motor function and lower limb muscle strength in Chinese women aged 80 years and older.

This study investigates the effects of a 12-week brisk walking exercise regimen on motor function improvements in elderly women. Twenty-six elderly women, aged 84.2 ± 3.2 years, participated in a 12-week brisk walking exercise program. Fitness assessments and blood biomarker analyses (including CHO, HDLC, LDLC, TC) were conducted pre- and post-intervention. Additionally, targeted metabolomics was employed to measure short-chain fatty acids, amino acids, and vitamin metabolites. The intervention led to significant enhancements in participants' flexibility (p < 0.05), lower limb muscle strength (p < 0.01), and cardiorespiratory endurance (p < 0.01), while muscle mass showed no significant changes. Fifteen significant differential metabolites were identified (VIP > 1.0, FC > 1.2 or < 0.8, and p < 0.05), with arginine, ornithine, aspartic acid, glutamine, phenylalanine, tyrosine, and pantothenic acid playing key roles across seven metabolic pathways. A 12-week brisk walking exercise program significantly enhanced flexibility, lower limb muscle strength, and cardiorespiratory endurance among elderly women. These improvements did not extend to muscle mass or upper limb muscle strength. The observed enhancement in exercise capacity may be attributed to improved regulation of neurotransmitters.

The Impact of a 12-Week Aqua Fitness Program on the Physical Fitness of Women over 60 Years of Age.

BACKGROUND: This study aimed to assess the impact of a 12-week Aqua Fitness program on the physical fitness of older women and emphasize sustainable health practices for aging populations. We focused on evaluating the program's effectiveness, using the Senior Fitness Test to measure improvements in physical capabilities. METHODS: An experimental research design was implemented, with 30 participants aged 60 and older. The participants were divided into a control group and an experimental group, each comprising 15 individuals. The control group received aqua Fitness exercises, and the experimental group received aqua fitness exercises and isometric (combined) exercises. Lower limb muscle strength, upper limb muscle strength, lower body flexibility, upper body flexibility, dynamic balance, agility, and endurance were assessed using the Senior Fitness Test. Assessments were conducted pre- and post-training. RESULTS: For a comparison within the group, combined exercises (aqua fitness and isometric exercises) had a significant effect on lower limb muscle strength, upper limb muscle strength, lower body flexibility, upper body flexibility on the right side, dynamic balance, agility, and endurance. Aqua fitness exercises alone showed significant effects on upper limb muscle strength, lower body flexibility, and endurance and no significant effects on other variables. For the comparison between groups, no significant differences were found between the effects of aqua fitness exercises and combined exercises on lower limb muscle strength, upper limb muscle strength, lower body flexibility, upper body flexibility, and endurance. Significant differences were found only in dynamic balance and agility between the two groups of aqua fitness and combined exercises. CONCLUSIONS: Although the combined program (aqua fitness and isometric exercises) had a greater effect on improving the physical fitness of older adults than aqua fitness alone, there was no significant difference between the two groups. Therefore, the results of this study highlight the potential of aqua fitness in promoting sustainable health and physical fitness in the older adult population.

Physical Fitness and Cognitive Function in Persons with Dementia and their Caregiver.

A cross-sectional design investigated the physical attributes of 15 dyads of people with dementia and their caregivers. Physical and cognitive markers determined deviations from clinical thresholds for loss of functional independence, where 100% of participants performed below criterion-referenced threshold values for aerobic endurance. Walking distance for people with dementia was associated with bath/shower activity (p = .007), transfers (p < .001), and mobility (p = .013). Less distance walked was associated with more assistance with self-care tasks. Physical deficits associated with low aerobic endurance and lower body strength compromised independence, placing dyads at risk for falls and mobility-related health issues.

Functional fitness and risk factors of older patients with diabetes combined with sarcopenia and/or frailty: A cross-sectional study.

AIM: To learn the functional fitness levels in older adults with diabetes combined with sarcopenia and/or frailty. DESIGN: A cross-sectional investigation study. METHODS: A total of 205 participants with type 2 diabetes were recruited from September 2019 to August 2020. All patients underwent diagnostic screening for sarcopenia and frailty, and were divided into combined group (the patients who had sarcopenia and/or frailty) and non-combined group (the patient who had no sarcopenia and/or frailty). The diagnostic criteria for sarcopenia applied was proposed by the Asian Working Group on Sarcopenia in 2019 and frailty status was assessed using FRAIL Scale. Functional fitness was measured using the Senior Fitness Test and compared between combined and non-combined groups. Biochemical data of blood routine, glycolipid, and hepatorenal function tests were acquired from medical records. Logistic regression analysis was applied to explore the factors associated with the sarcopenia and/or frailty in the older adults with diabetes. RESULTS: Compared with non-combined group, the participants in combined group exhibited shorter 6-min walk distance, fewer repetitions of arm curls and chair stands, smaller back scratch and chair sit-and-reach values, and longer time in the 8-ft up-and-go test. The patients in the combined group had significantly lower level of red blood cell, haemoglobin, haematocrit, and higher level of platelet and blood urea nitrogen. Apart from calf circumference, physical activity, and insulin injection treatment, 6-min walk distance was the factor associated with diabetes combined with sarcopenia and/or frailty.

Frailty Prevention Care Management Program (FPCMP) on Frailty and Health Function in Community-Dwelling Older Adults: A Quasi-Experimental Trial Protocol.

BACKGROUND: Frailty often results from deteriorating muscle strength and decreased physical function in older adults. Frailty includes not only physical components, but also psychological and social aspects. Previous research has shown that exercise programs, especially resistance exercises combined with nutritional care, can reduce frailty. OBJECTIVES: This study aimed to develop a Frailty Prevention Care Management Program that prevents frailty and improves physical activity and nutrition compared to usual care for community-dwelling older adults. METHODS: A quasi-experimental and single-blinded trial with a non-equivalent control group using a before-after design will be performed involving Frailty Prevention Care Management Program interventions, taking place both at the communities. Participants will be divided into two different intervention groups and two control groups. All groups will be assessed three times: at baseline, immediately after the intervention, and 3 months post intervention. A total of 72 community-dwelling older adults are recruited. This intervention includes an exercise program (design TRX program) and nutritional education. The control group will not receive any specific exercise training. The primary outcome shall comprise the effect of the Frailty Prevention Care Management Program on frailty using the Taiwanese version of the Tilburg frailty indicator. Secondary outcomes include the effect of physical activity using the Senior Fitness Test and nutrition measures using the Mini Nutritional Assessment-Short Form. A generalized estimating equation is constructed to analyze the effects of the intervention. CONCLUSIONS: This trial will provide vital information to guide interventions to improve outcomes (frailty, physical activity, and nutrition) and inform the integration of nutrition and TRX exercises in community-dwelling older adults.

Functional fitness trends among older adults in Portugal between 2008 and 2018: Keeping up with a healthy aging process.

OBJECTIVES: Maintaining a healthy aging process is vital to combating and delaying the adverse health outcomes faced by the growing older adult population, where a key aspect to achieving healthy aging is the preservation of functional fitness. This study aims to present trends on the functional fitness of Portuguese older adults between 2008 and 2018 and build new normative reference standards for the Senior Fitness Battery Tests. DESIGN: Cross-sectional study. METHODS: Functional fitness was measured with the Senior Fitness Battery Tests in two national representative cohorts of the Portuguese older adult population (≥65 years) using the 2008 (n = 4712) and 2018 (n = 2717) surveys. Changes were assessed according to sex and age group. Sex and age-group normative fitness scores were developed. RESULTS: Overall findings suggested that older adults' point prevalence for arm-curl, 8-ft up-and-go, and 30-s chair sit-to-stand remained stable between 2008 and 2018, with declining trends being observed for the 6-min walk and back-scratch tests. However, results for trends varied when stratified by sex and age categories. CONCLUSIONS: Our results suggest a trend toward a stabilization of most of the functional fitness tests over the past decade, but with a critical decline in the 6-min walk test. Thus, this test should be targeted by future health-care policies. Moreover, this investigation provides new and updated normative reference standards for the Senior Fitness Battery Tests that should be used as a tool to promote a healthy aging process among Portuguese older adults.

Explanatory Capacity of Postural Control and Physical Fitness in Cognitive Impairment and Support Needs among Individuals with Intellectual Disabilities-A Cross-Sectional Pilot Study.

Postural control is a skill associated with most motor activities and is essential for the performance of activities of daily living. People with intellectual disabilities (ID) present postural control deficits that can be attributed to several causes. The aim of this study was to determine whether postural control and physical fitness could explain the cognitive impairment and support needs in this population. A cross-sectional pilot study was conducted with 18 people with ID. Data collection was based on assessments for postural control (Mini BESTest and Berg Balance Scale) and physical fitness (Senior Fitness Test). The data were analyzed using linear regression models. Anticipatory postural adjustments were associated with support needs, explaining up to 45% of these. Consecutive postural adjustments and upper limb strength were less significantly associated with support needs. However, none of the variables used explained cognitive impairment in ID. Knowledge of the relationships and behavior of the different measurement tools is essential for the development of appropriate interventions in this population.

Functional Capacity of Noninstitutionalized Older Adults from Northwest Mexico: Reference Values.

INTRODUCTION: Physical capacity (PC) is a strong determinant of health, quality of life, and functional independence in older adults. Having reference values for PC specific to a particular region allows for a contextual interpretation of an individual's level. OBJECTIVES: The objectives of this study were to describe the evolution of key aspects of PC during the aging process and provide reference values for the major components of health-related PC for the older adult population in Northwest Mexico. METHODS: A total of 550 independent older adults (60-84 years, 70% women) from the city of Hermosillo (Sonora, Mexico) were included between January and June 2019. PC was assessed using the Senior Fitness Test Battery (SFTB) and grip-strength test. Reference values were established for 5-year age groups, providing percentile values at 10, 25, 50, 75, and 90. The percentage decrease in functional capacity with aging was determined via a linear regression analysis of age against the percentage value of each subject relative to the average value of 60-year-old individuals of the same sex. RESULTS: Statistically significant differences in the results between men and women within the same age group were few and inconsistent, except for handgrip strength, which was lower in women across all age groups. The functional level, with respect to reference values for each age and sex group, was similar between men and women. The most pronounced functional decline during the aging period occurs between 70 and 80 years of age. The various tests generally show an annual percentage loss of approximately 1% from 60 years of age. CONCLUSIONS: This is the first study in Mexico that provides reference values for physical capacity using the Senior Fitness Test Battery. In general, older adults-both men and women-show similar functional levels with respect to their respective reference values. In general, an annual decline of 1% from the age of 60 years occurs.

Symptoms of Sarcopenia and Physical Fitness through the Senior Fitness Test.

INTRODUCTION: Physical fitness concerns a set of attributes related to the ability to perform physical activity that may justify the symptoms reported by the elderly in the context of sarcopenia. OBJECTIVE: This study aimed to investigate the relationship between the perception (symptomatology) of physical functioning (what the person thinks they are capable of) and the capacity itself for physical functioning in elderly people in northern Brazil. METHODS: Cross-sectional study that analyzed 312 elderly people (72.6 ± 7.8 years) from the city of Novo Aripuanã, Amazonas, Brazil. Sarcopenia symptomatology was assessed using the SARC-F, a 5-item questionnaire designed for screening sarcopenia in older individuals in five domains: strength, walking aids, difficulty getting up from a chair, difficulty climbing stairs, and falls. Physical fitness was assessed by the Senior Fitness Test (SFT) battery including balance evaluated with the short version of the Fullerton Advanced Balance scale (FAB). RESULTS: ROC curve analysis revealed that the tests with the greatest ability to discriminate participants with significant symptoms for sarcopenia (≥4 points on SARC-F) were arm curl and 6 min walk: the probability of suspected sarcopenia increased exponentially with an arm curl < 11.5 reps for men (se = 71%; sp = 69%; AUC = 0.706, 95% CI: 0.612-0.788; p = 0.013) and women (se = 81%; sp = 51%; AUC = 0.671, 95% CI: 0.601-0.735; p ≤ 0.001) or with a 6-min walk <408.5 m for men (se = 71%; sp = 63%; AUC = 0.720, 95% CI: 0.628-0.690; p = 0.001) and <366.0 m for women (se = 69%; sp = 58%; AUC = 0.692, 95% CI: 0.623-0.755; p = 0.0001). CONCLUSIONS: Physical fitness assessed through the senior fitness test, particularly the 30-s-arm curl test and the 6-min walk test, can discriminate for suspected symptoms of sarcopenia.

An Exergame-Integrated IoT-Based Ergometer System Delivers Personalized Training Programs for Older Adults and Enhances Physical Fitness: A Pilot Randomized Controlled Trial.

INTRODUCTION: Regular physical exercise is believed to counteract the adverse physiological consequences of aging. However, smart fitness equipment specifically designed for older adults is quite rare. Here we designed an exergame-integrated internet of things (IoT)-based ergometer system (EIoT-ergo) that delivers personalized exercise prescriptions for older adults. First, physical fitness was evaluated using the Senior Fitness Test (SFT) application. Then, radio frequency identification (RFID) triggered the EIoT-ergo to deliver the corresponding exercise session based on the individual level of physical fitness. The exercise intensity during each workout was measured to generate the next exercise session. Further, EIoT-ergo provides an exergame to help users control and maintain their optimal cadence while engaging in exercise. METHODS: This was a randomized controlled trial with 1:1 randomization. Participants were older adults, 50+ years of age (N = 35), who are active in their community. Participants in the EIoT-ergo group received a 12-week personalized exercise program delivered by EIoT-ergo for 30 min per session, with 2 sessions per week. Participants in the control group continued with their usual activities. A senior's fitness test and a health questionnaire were assessed at baseline and at a 13-week reassessment. The Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST) was used to evaluate the satisfaction of EIoT-ergo. RESULTS: Compared with the control group, the EIoT-ergo group showed significant improvements in muscle strength (time-by-group interaction, sit-to-stand: ß = 5.013, p < 0.001), flexibility (back stretch: ß = 4.008, p = 0.005; and sit-and-reach: ß = 4.730, p = 0.04), and aerobic endurance (2-min step: ß = 9.262, p = 0.03). The body composition was also improved in the EIoT-ergo group (body mass index: ß = -0.737, p < 0.001; and skeletal muscle index: ß = 0.268, p = 0.03). Satisfaction with EIoT-ergo was shown in QUEST, with an average score of 4.4 ± 0.32 (5 for very satisfied). The percentage maximum heart rate in each session also indicated that EIoT-ergo can gradually build up the exercise intensity of users. CONCLUSIONS: EIoT-ergo was developed to provide personal identification, exergames, intelligent exercise prescriptions, and remote monitoring, as well as to significantly enhance the physical fitness of the elderly individuals under study.

Sex-Related Differences in Functional Fitness Outcomes in Older Adults.

Sex-related differences in changes in functional fitness over time were longitudinally assessed in older adults participating in a group-based multimodal exercise program. From a database, functional fitness scores were obtained for 89 older adults (71.6 ± 6.5 years old) who had completed two assessments, 5-8 years apart. Lower body strength, upper body strength, aerobic endurance, flexibility, and change of direction performances were compared over time and with normative values. Females (p = .02), but not males, had an improvement in upper body strength over time. Females were also more flexible than males at both assessments (p ≤ .02). Of those who had five consecutive assessments, females were more flexible than males (p ≤ .05) and had a faster change of direction ability (p < .001). When compared with normative values, our results indicate that typical time-related functional fitness loss can be attenuated with group exercise. Our results further support the need to tailor exercise prescription according to the individual.

Effects of Twenty-Four Weeks of Resistance Exercise Training on Body Composition, Bone Mineral Density, Functional Fitness and Isokinetic Muscle Strength in Obese Older Women: A Randomized Controlled Trial.

Resistance exercise effectively improves bone mineral density (BMD) and muscle quality (e.g., muscle mass and muscle strength). The present study aimed to examine the effect of a 24-week resistance exercise training (RT) program on body composition, BMD, functional fitness, and isokinetic muscle strength in obese older women. Forty obese older women were initially enrolled. Among them, 30 participants (age: 80.55 ± 4.94 years; body fat percentage: 36.25 ± 3.44%) completed the study. The participants were randomly assigned into two groups: the RT group (n = 15) and the control (CON) group (n = 15). The RT group participated in the exercise for 60 min per session and two sessions per week for 24 weeks. Pre-test and post-test body composition, BMD, functional fitness, and isokinetic muscle strength were evaluated. The RT group increased significantly in functional fitness (hand grip strength: 1.70 kg, p < 0.01, and lower body strength: 3.87 n, p < 0.001), and isokinetic muscle strength (non-dominant leg extensor peak torque %BW at 60°/s: 13.20%, p < 0.05, dominant leg (DL) flexor peak torque at 60°/s: 3.87 Nm, p < 0.05, and DL flexor peak torque %BW at 60°/s: 7.60%, p < 0.05). However, the CON group showed negative changes in body composition (fat mass: 1.15 kg, p < 0.001, body fat percentage: 1.59%, p < 0.001, and fat-free mass: -0.58 kg, p < 0.05), BMD (whole-body: -0.01 g/cm2, p < 0.001 and forearm: -0.01 g/cm2, p < 0.05), functional fitness (lower body flexibility: -3.23 cm, p < 0.01, upper body strength: -2.06 n, p < 0.01, and agility and dynamic balance: 0.54 s, p < 0.01), and isokinetic muscle strength at 60°/s and 180°/s (all peak torque % body weight variables: -7.31--1.50, p < 0.05). Our findings show that the CON group negatively affects body composition, BMD, functional fitness, and isokinetic muscle strength in obese older women for 24 weeks.

Selected Elements of Lifestyle and the Level of Functional Fitness in Older Women.

BACKGROUND: The appropriate level of functional fitness is a very important element for seniors to maintain self-reliance in daily life. The aim of this research was to assess sociodemographic differences, selected elements of lifestyle, and functional fitness in the older residents of social welfare homes and community dwellers Methods: The analysed group comprised 693 women aged 65-79, including 173 subjects living in social welfare homes and 520 community-dwelling women. Basic anthropometric features were measured, and functional fitness was assessed using the Senior Fitness Test. Basic sociodemographic characteristics, as well as data on health self-assessment and selected elements of lifestyle, were also collected. RESULTS: The female residents of social welfare homes were found to have a lower body mass index (BMI), and they came from smaller cities, compared with community-dwelling older women. Furthermore, almost a third of them had no children and completed primary or vocational education. They also reported smoking, poor health conditions, and lack of physical activity. The functional fitness of women living in social welfare homes was significantly lower than in community-dwelling women. CONCLUSIONS: As seniors living in social welfare homes have such a significantly reduced level of functional fitness, compared with their peers living independently, it is necessary to include them in adaptive physical activity and diversified daily activities.

Beyond Sarcopenia: older adults with type II diabetes mellitus tend to experience an elevated risk of poor dynamic balance-a case-control study.

BACKGROUND: People with type 2 diabetes mellitus (T2DM) tend to be vulnerable to geriatric syndromes such as sarcopenia and frailty. Reduced physical activity also accompanies sarcopenia and frailty, which is generally typical of patients with T2DM. However, a comprehensive assessment of physical fitness in patients with T2DM has seldom been carried out and verified. This study is thus an attempt to determine the associations among sarcopenia, frailty, and the SFT in diabetic patients and non-diabetic controls to provide a more comprehensive understanding of such associations in future evaluations of T2DM in older individuals. METHODS: Sarcopenia, frailty, and the senior fitness test (SFT) were compared between 78 older men with T2DM (66.5 ± 9.0 years) and 48 age-matched normoglycemic controls (65.8 ± 5.3 years) in this case-control study. The skeletal muscle index (SMI), grip strength, and 4-m walk test were employed to assess for sarcopenia. Frailty was evaluated using the Study of Osteoporotic Fractures index (SOF). The SFT comprises five components, including body composition, muscle strength, flexibility, balance, and aerobic endurance. RESULTS: The risk level of sarcopenia was significantly higher (p < 0.05) in the T2DM group as compared to the control group. No significant difference between-group differences were found in SMI and grip strength in the T2DM and control groups. However, the T2DM group showed a significant decrease in gait speed (p < 0.01) in comparison with the control group, as well as significant increases in frailty (p < 0.01) and depression (p < 0.05). With respect to the SFT, obvious elevation in BMI, significant declines in extremity muscle strength (elbow extensor, knee flexor, hip abductor, hip flexor, sit to stand), static/dynamic balance (single leg stand: p < 0.05; up-and-go: p < 0.01) and aerobic endurance (2-min step: p < 0.01; 6-min walk: p < 0.01) were found in the T2DM group. Furthermore, the SOF (OR = 2.638, 95% CI = 1.333-5.221), BMI (OR = 1.193, 95% CI = 1.041-1.368) and up-and-go (OR = 2.089, 95% CI = 1.400-3.117) were found to be positively and significantly associated with T2DM. CONCLUSIONS: The findings of this study indicated the importance of countering frailty and maintaining physical fitness, especially dynamic balance, during the early physical deterioration taking place in diabetic patients.

Physical activity and physical fitness according to loneliness levels in adults 50+ / Caraterização da atividade física e aptidão física de acordo com os níveis de solidão em adultos 50+

Loneliness is a perception of dissatisfaction that seems to be the result of a lack of significant re-lationships, with multiple potential causal factors. The current body of research is not conclusive in relation to the link between loneliness and physical activity (PA) and physical fitness (PF) in adults and seniors. The aim of this cross-sectional study is to characterize PA and PF according to levels of loneliness (Social Isolation versus Affinities). The 62 Portuguese individuals (64.68 ± 6.85 years; 68% women) were assessed for loneliness (University of California Los Angeles 16-item Loneliness Scale - UCLA-16). and classified in Social Isolation or Affinities, i.e., presence of significant social rela-tionships. PA was estimated using a questionnaire (International PA Questionnaire - Short Version - IPAQ-SV ) and PF was evaluated using the Senior Fitness Test (upper and lower body strength, upper and lower body flexibility, cardiorespiratory fitness, agility and dynamic balance). Descriptive statistics were used. The comparison between groups was performed using parametric (t-test, AN-COVA adjusted to sex and chi-square) and non-parametric tests (Mann-Whitney). The prevalence of social isolation was 53%. The individuals of the Affinities group spent more minutes per day on moderate and vigorous physical activity (MVPA) than the individuals of the Social Isolation group (0.00 [0.00 ­ 12.86] versus 11.43 [0.00 ­ 17.14] minutes, respectively; p = 0.041). After adjusting for sex, the differences were no longer significant. Loneliness groups were not different in relation to PF. PA appears to contribute to a better mental profile in adults and seniors. The results should be confirmed through studies with larger samples

A solidão é uma percepção de insatisfação que parece resultar da carência de relacionamentos significativos, sendo múltiplos os seus potenciais fatores causais. A atual evidência não é robusta no que diz respeito à associação da solidão com a atividade física (AF) e aptidão física (ApF) em adultos 50+. O objetivo deste estudo transversal é caracterizar a AF e ApF de acordo com a solidão. Os 62 indivíduos portugueses (64,68 ± 6,85 anos; 68% mulheres) foram avaliados para solidão (Escala de Solidão de 16 itens da Universidade da Califórnia em Los Angeles - UCLA-16) e classificados como Isolamento Social ou Afinidades, i.e., presença de relações socias significativas. A AF foi estimada por questionário (Questionário Internacional de AF - Versão Curta - IPAQ-SV ) e a ApF medida pela bateria Senior Fitness Test (força de membros superiores e inferiores, flexibilidade de membros superiores e membros inferiores, aptidão cardiorrespiratória e agilidade e equilíbrio dinâmico. Foram utilizadas estatísticas descritivas. A comparação entre grupos foi realizada através de testes paramétricos (teste-t, ANCOVA ajustada ao sexo e qui-quadrado) e não paramétricos (Mann-Whitney). A prevalência de isolamento social foi de 53%. O grupo Afinidades apresentou mais AF moderada a vigorosa comparativamente ao grupo Isolamento Social (11,43 [0,00 ­ 17,14] vs (0,00 [0,00 ­ 12,86], respetivamente; p = 0,041). Após ajuste para o sexo, as diferenças deixaram de ser significativas. Os grupos de solidão não foram diferentes relativamente à ApF. A AF parece contribuir para um melhor perfil mental de adultos e idosos, contudo, os resultados devem ser confirmados em estudos com amostras maiores

Normative values and integrated score of functional fitness among Chinese community-dwelling older adults in Suzhou.

Objectives: This study was performed to establish the normative values and integrated score of the functional fitness on the basis of the senior fitness test (SFT) among Chinese community-dwelling older adults in Suzhou. Methods: In this cross-sectional descriptive study, 1,122 community-dwelling older adults aged 60 years old and above were recruited at Suzhou, China, by using a multistage stratified sampling method and accepted the SFT measurements. Sex- and age-specific normative values of each index of the SFT were established by using the percentile method. The SFT integrated score was established using factor analysis according to the data of 70% of the participants (construction group) and verified using the error rate from the data of the remaining 30% of the participants (verification group). Results: Normative-referenced percentile values at the 5th, 10th, 25th, 35th, 50th, 65th, 75th, 90th, and 95th percentiles for each index of SFT were established for the men and women among the different age groups. Five indices of the SFT, namely, 2-min step test, 30-s arm curl, 30-s chair stand, chair sit-and-reach, and 8-ft up-and-go (TUGT), gradually declined with age in both sexes (p < .05). The SFT integrated score was calculated as follows: F = 3.8 × 2-min step test + 3.8 × 30-s arm curl + 3.8 × 30-s chair stand + 2.2 × back starch + 2.6 × chair sit-and-reach + 4 × TUGT - .04 × BMI. The formula was verified using the error rate. The error rates of the verification group compared with the construction group in each grade score of SFT were lower than 5%. Conclusion: Based on the data from the community-dwelling older adults in Suzhou, China, the functional fitness normative values for each index of the SFT and the integrated score of SFT were established. The SFT integrated score formula was verified to be reasonable and effective.

Health-Related Functional Fitness within the Elderly Communities of Five European Countries: The in Common Sports Study.

(1) Background: The purpose of this study was to analyse the functional fitness and the anthropometric values of older adults participating in the "IN COMMON SPORTS" project. (2) Methods: A total of 418 participants (eastern European Group (GEE, n = 124) and southern European Groups (GES, n = 294) have been evaluated for anthropometric characteristics and fitness. (3) Results: The GES participants presented significant differences in anthropometric values and fitness, with the best values for upper and lower limb strength and aerobic resistance, while those from the GEE presented significantly better values for lower limb flexibility. (4) Conclusion: Older adults present differences in fitness in accordance with their country of residence, with the GES having the best functional fitness.

Effects of marine oligomeric polyphenols on body composition and physical ability of elderly individuals with sarcopenia: a pilot study.

PURPOSE: We aimed to identify the effects of marine oligomeric polyphenol (MOP) intake in elderly individuals with sarcopenia. METHODS: Older adults (aged 65 years or older) were recruited based on the diagnostic criterion for sarcopenia and were randomly assigned to the MOP intake group (n=10) or the placebo (PBO) intake group (n=10). To determine the effect of MOP intake received for four weeks, the pre- and post-intake body composition (weight, skeletal muscle mass, and bone density) and senior fitness tests were assessed. RESULTS: Our results showed there were significant differences in the skeletal muscle mass (p=0.039), bone density (p=0.020), fat-free mass index (p=0.026), and 2.4 m up and go test (p=0.001) between pretest and post-test. There was a significant difference between the pre-test and post-test and an interaction effect for the one-leg stand test (p=0.010 and p=0.049, respectively). However, there were no significant differences in body fat percentage, calf circumference, grip strength, or the chair rise test. CONCLUSION: Some variables exhibited significant differences in the pre- and post-assessments, and there was an interaction effect for the one-leg stand. However, this was insufficient to prove the effectiveness of MOP intake in improving sarcopenia. Therefore, additional studies are essential to examine the effects of MOP intake and exercise intervention on the body composition and fitness of patients over a longer period.
