Malnutrition is a well-known risk factor for deteriorated physical function, disability and loss in independence in older adults. An unintended loss in body weight of more than 5% in 3 months is one indicator for malnutrition. In this study we examined the relationship between meal preparation time, hand grip strength, and body weight in order to map impending nutritional problems using ambient sensors. Data were collected in the domestic environments of 20 (pre-) frail older adults aged 85.75 y (Standard Deviation: 5.19 y) over 10-months of observation. Collecting included physical function and nutritional status of the participants and meal preparation time by a combination of motion and power sensor events. Analysis was done by rank correlation of hand grip strength, body weight, and meal preparation time. Ten participants aged 85.1 years (Standard Deviation: 4.6 y) were included. The results show a significant correlation (≥0.99) of the meal preparation time with the hand grip strength. This result validated the meal preparation time as a suitable measure for analysing the correlation between meal preparation time and body weight, and a significant correlation (≥0.99) found. Hence the meal preparation time could be used as an indicator for malnutrition. However, causalities have to be conducted by further clinical studies.

Abstract Background: Frailty is a common geriatric syndrome, characterized by reduced physiologic reserve and increased vulnerability to stressors, due to cumulative decline in multiple physiological systems. We studied the feasibility of a community-delivered Baduanjin (BDJ) training program among pre-frail/frail community-dwelling older people. We examined 1) safety (adverse events), physical and psychological effects; and 2) feasibility of recruitment, retention, adherence; recruitment efforts and any program challenges, so as to inform future studies.Methods: Our study was a single arm pre-post study in a community setting. Sixteen week group BDJ training (2x/week in the first 4 weeks, and 3x/week thereafter) co-designed and implemented by community-based providers in Singapore. Recruitment, attendance and adverse events were recorded throughout the training. A participants’ survey was also administered after the training program. Effects of the intervention on physical and functional outcomes (hand grip strength, knee extension strength, Time Up and Go (TUG), Physiological Profile Assessment (PPA), 30-second Sit-to-Stand test, 6-meter fast gait speed test), frailty outcomes (frailty score and status), and other outcomes (Maastricht Questionnaire (MQ), Fall Efficacy Scale (FES), Montreal Cognitive Assessment (MoCA), Geriatric Depression Scale (GDS), and EQ-5D-5L) were examined before and after the program.Results: Of 31 older adults screened to be frail, 15 met inclusion criteria and 3 refused participation, resulting in 12 older adults (9 women) enrolled into the program. During the program, one participant was hospitalized (unrelated to BDJ training) and the other 11 (aged 77±6 years; 2 frail, 9 prefrail at baseline) completed the program with average overall attendance of 89%. Most (89%) of the 44 training sessions had attendance >80%. The program received positive feedback with no training-related adverse events. Participants either reversed (n=2) or maintained (n=9) their frailty statuses. There post-training outcomes in hand grip strength, knee extension strength, TUG , MQ , FES , MoCA , GDS and EQ-5D-5L index score appeared to be better. The reduction of frailty and PPA fall risk scores were of moderate-to-large effect size. Conclusions: Community-delivered BDJ training program was safe and feasible for prefrail/frail older adults with the potential to improve physical and cognitive function, reduce fall risk, improve psychological well-being, and reverse frailty status.

Introduction Aging is associated with subtle cognitive decline in attention, memory, executive function, processing speed, and reasoning. Although lower brain-derived neurotrophic factor (BDNF) has been linked to cognitive decline among older adults, it is not known if the association differs among individuals with various BDNF Val66Met (rs6265) genotypes. In addition, it is not clear whether these associations vary by hand grip strength or physical activity (PA). Methods A total of 2904 older adults were included in this study using data from the Health and Retirement Study. Associations between serum BDNF and measures of cognitive function were evaluated using multivariable linear regression models stratified by Met allele status. PA and hand grip strength were added to the model to evaluate whether including these variables altered associations between serum BDNF and cognition. Results Mean age was 71.4 years old, and mean body mass index was 28.3 kg/m2. Serum BDNF levels were positively associated with higher total cognitive score (beta = 0.34, p = .07), mental status (beta = 0.16, p = .07), and word recall (beta = 0.22, p =.04) among Met carriers, while serum BDNF levels were negatively associated with mental status (beta = −0.09, p = .07) among non-Met carriers. Furthermore, associations changed when hand grip strength was added to the model but not when PA was added to the model. Conclusions The BDNF Val66Met variant may moderate the association between serum BDNF levels and cognitive function in older adults. Furthermore, such associations differ according to hand grip strength but not PA.

The hands are anatomically specialized for manipulative tasks with different physical objects, where they can cope with certain loads with different forces and intensity. During various physical and sports activities, the hands produce the appropriate muscular force for gripping, which manifests as the hand grip's force. For this reason, hand grip strength (HGS) is recognized as a limiting factor in all manipulative activities performed by the cranial part of the body. The current research included a sample of 22 subjects, 16 male Body Height (BH=180.28±4.65cm); Body Weight (BW=80.05±9.96kg), Body Mass Index (BMI=24.61±2.74kg/m²) and 6 female subjects Body Height (BH=167.42±11.11cm); Body Weight (BW=64.80±10.09kg); Body Mass Index (BMI=23.02±1.57kg/m²) on the third year of study at the Faculty of Physical Education and Sports. This study aimed to determine the maximum isometric muscle force of the handgrip and differences between the same gender of students. A t-test for small samples was applied for data processing, and the relevant statistical parameters were calculated. The obtained t-test results confirmed statistically significant differences between the so-called dominant and non-dominant hands in male subjects (t=4.158; p<0.05) and female subjects (t=3.176; p<0.05). The obtained results of this research will be used for analytical and diagnostic purposes with a wide range of activities in the population of physical education and sports students (assessment of physical ability, trends, and tendencies to monitor and change abilities, influence on the implementation of certain curricula of some subjects studied at the faculty, etc.).

Abstract Background Frailty is a common geriatric syndrome, characterized by reduced physiologic reserve and increased vulnerability to stressors, due to cumulative decline in multiple physiological systems. Our study examined the feasibility and effects of a community-delivered BDJ training program among pre-frail/frail community-dwelling older people in preparation for a randomised control implementation study.Methods Our study was a single arm feasibility study in community setting. Eleven participants (aged 77 ± 6 years; 2 frail, 9 prefrail at baseline) completed the program. Sixteen week group BDJ training co-designed and implemented by community-based providers in Singapore.

One participant was hospitalized (unrelated to BDJ training) and the other 11 completed the program with average overall attendance of 89%. Most (89%) of the 44 training sessions had attendance > 80%. The program received positive feedback with no training-related adverse events. Participants either reversed (n = 2) or maintained (n = 9) their frailty statuses. There were significant within-group post-training improvements in hand grip strength (p = 0.013), knee extension strength (p = 0.048), TUG (p = 0.018), MQ (p = 0.001), FES (p = 0.022), MoCA (p = 0.014), GDS (p = 0.028), EQ-5D-5L index score (p = 0.029). The reduction of frailty score and PPA fall risk score showed moderate-to-large effect size.Conclusions Community-delivered BDJ training program was safe and feasible for prefrail/frail older adults with the potential to improve physical and cognitive function, reduce fall risk, improve psychological well-being, and reverse frailty status.
