Abstract

Each year in the world, especially in Indonesia, many elderly people exposed to higher risk of dementia due to an increased number of the elderly population and the incidence of mild cognitive impairment in the elderly. The aim of this study is to find out what factors are related with cognitive function in the elderly population. The study used analytic method with cross sectional study design. Subjects were 60 elderly people; male or female ≥ 60 years old. Data were analysed with Chi Square Test (α = 0.05). Cognitive function was measured by MMSE test. The result were found a significant relation between age and cognitive function ( p = 0.014), level of education and cognitive function (p value = 0.000), physical activity and cognitive function (p value = 0.003), cognitive activity and cognitive function (p value = 0.002), and social interaction and cognitive function (p value = 0.000). Gender variable did not have relation with cognitive function (p value = 0.343). This study conclude that there was a relation between age, education level, physical activity, cognitive activity and social interaction with cognitive function in the elderly population. There was no relation between gender and cognitive function in the elderly population.Keywords: cognitive function, cognitive impairment, elderly, MMSE

Abstract

Elderly people are a group of people with age of 60 and above. Studies in United States showed one-third of elderly people experienced fall in their houses and one-forty of them need bedrest in hospital. Falling can cause physical and mental injury. Physical injury manifests as fracture, hematoma, bruises, and dislocation, and mental injury manifests as lack of self esteem. This study aimed to examine the relation between age and gender on risk of fall on elderly people. This is a cross-sectional analytical study involving 23 elderly people from Tulus Kasih Elderly Home that met the inclusion criteria. Risk of fall were checked with Timed Up and Go Test. The data acquired were analyzed with chi-square with α = 0,05. As results, age significantly affected risk of fall (p=0.019) but gender did not (p=0.265). We concluded the risk of falling is increased with age and unaffected by gender.Keywords : age, gender, risk of fall, timed up and go test

Abstract

Rhythm, melody, and high frequencies in Mozart’s music are capable to stimulate creativity and motivation regions of the brain and activate brain’s areas, especially the prefrontal area of the brain, which contributes to short-term memory. Listening to Mozart ‘s music can enhance concentration because it stimulates alpha brain waves which induce relaxation and peaceful mood. The objectives of this study were to determine the Mozart’s effect towards short-term memory and concentration. This is a quasi-experimental study using pre- and post-test design, performed to 30 adult women aged between 19-24 years old. The measured data were memorized words from recall memory test and duration to finish traffic jam puzzle, before and after listening to Mozart Sonata K448 for Two Pianos in D-major 2nd Movement. Data were analyzed using paired t-test with ? = 0.05.The results showed that there is a significant difference of words remembered before and after listening to music (35,43±6,70444 vs 73±4,727; p<0,01) and duration to finish traffic jam puzzle (125,60±149,939vs 53,67±69,652 seconds ; p<0,01). We concluded that Mozart’s music improves short-term memory and concentration. Keywords: Mozart’s sonata, short-term memory,concentration

Abstract

Resistance training has grown in importance for managing oxidative stress, particularly in adults, as it enhances muscle development and overall health. However, it also leads to the formation of reactive oxygen species (ROS), which can result in cellular oxidative damage and potentially hasten the aging process. This review assesses the role of astaxanthin, a powerful antioxidant, in counteracting oxidative stress during resistance training, with a focus on its effects on aging. This study employs a narrative review methodology, evaluating peer-reviewed publications from 2019 to 2024. Keywords used include "Aging," "Antioxidant," "Astaxanthin," "Oxidative Stress," and "Adults." Twenty-five articles were selected for in-depth analysis. The findings suggest that astaxanthin supplementation notably decreases oxidative stress markers, particularly plasma malondialdehyde (MDA) levels, in individuals undergoing resistance training. On a molecular level, astaxanthin activates the Nrf2 pathway, which is responsible for regulating antioxidant enzyme production and supports mitochondrial biogenesis through the PGC-1α pathway. This dual mechanism not only reduces oxidative damage but also enhances energy metabolism, helping maintain cellular function and delaying age-related decline. In conclusion, incorporating astaxanthin supplements into resistance training routines offers promising potential for reducing oxidative stress and promoting healthy aging in adults.

Abstract

Background: Cardiac aging is closely associated with mitochondrial dysfunction and impaired quality control mechanism. Exercise has been shown to modulate mitochondrial homeostasis, however, its effects on cardiac mitophagy and mitochondrial dynamics during aging remain unclear. This study investigated the effects of moderate-intensity treadmill training on mitochondrial maintenance-related gene expression in the hearts of young and aged Wistar rats.Methods: Young and aged rats were divided into four groups: young control, young exercise, aged control, and aged exercise (n=6 per group). Exercise groups performed treadmill running at 20 m/min for 30 minutes/day, 5 days/week for 8 weeks. Cardiac gene expression levels of Pink1, Parkin, Mfn1, Mfn2, Opa1, Drp1, and Fis1 were analyzed using semi-quantitative polymerase chain reaction (PCR). Data were analyzed using one-way ANOVA or Kruskal–Wallis test followed by appropriate post hoc analyses.Results: Exercise significantly increased Mfn2 expression in aged exercise rats compared with aged controls (p=0.029), suggesting partial restoration of age-related decline. Expression of Mfn1 and Drp1 varied among groups but showed no significant pairwise differences. Expression levels of Opa1, Fis1, Pink1, and Parkin remained unchanged. These results indicate that moderate exercise selectively enhances mitochondrial fusion capacity while maintaining balanced fission and basal mitophagy activity.Conclusion: Moderate-intensity treadmill training promotes mitochondrial  fusion-related adaptation in aging cardiac tissue. Regular moderate exercise may represent a potential non-pharmacological strategy to support mitochondrial function and mitigate cardiovascular aging.

Abstract

BackgroundUrban lifestyles have become increasingly sedentary, contributing to reduced physical fitness. Muay Thai, a high-intensity martial art, has been proposed as an effective exercise modality to improve aerobic capacity and muscle endurance. This study aimed to evaluate the effects of different weekly Muay Thai training frequencies on VO₂ max and muscle endurance in non-athletic adults. MethodsA randomized experimental study with a pre-test–post-test design was conducted involving 40 non-athletic adults (aged 20–25 years). Participants were randomly allocated into two groups: training twice weekly (MT2X) or four times weekly (MT4X) for eight weeks. Outcomes included VO₂ max and upper, abdominal, and lower body muscle endurance. Baseline characteristics were described descriptively. Between-group differences in post-intervention outcomes were analyzed using analysis of covariance (ANCOVA), with baseline values included as covariates. ResultsAt baseline, VO₂ max, abdominal, and lower body muscle endurance were higher in the MT4X group. After adjustment for baseline values using ANCOVA, the MT4X group demonstrated significantly higher post-intervention VO₂ max compared with the MT2X group (adjusted mean difference, p<0.001). Significantly greater improvements favoring the MT4X group were also observed for upper body muscle endurance (push-ups, p<0.001), abdominal muscle endurance (sit-ups, p<0.001), and lower body muscle endurance (squats, p=0.018). ConclusionA higher frequency Muay Thai training program is effective in significantly improving participants' aerobic capacity and muscle endurance. Practitioners are able to choose their training frequency preference, since both frequencies provide similar adaptation.
