AI Article Synopsis
- The study explores the impact of regular exercise on brain activity in elderly people compared to young adults, aiming to understand underlying neurophysiological mechanisms.
- A total of 71 participants were analyzed, with data collected through various physiological signals while performing different exercise loads on a stationary bike.
- Results indicated that regular exercise in the elderly led to significant positive changes in brain activity, while those who exercised occasionally showed no such benefits; young regular exercisers exhibited better overall efficiency in both cardiac and neurobiological functions.
Article Abstract
Numerous studies indicated the physical benefits of regular exercise, but the neurophysiological mechanisms of regular exercise in elders were less investigated. We aimed to compare changes in brain activity during exercise in elderly people and in young adults with and without regular exercise habits. A total of 36 healthy young adults (M/F:18/18) and 35 healthy elderly adults (M/F:20/15) participated in this study. According to exercise habits, each age group were classified into regular and occasional exerciser groups. ECG, EEG, and EMG signals were recorded using V-AMP with a 1-kHz sampling rate. The participants were instructed to perform three 5-min bicycle rides with different exercise loads. The EEG spectral power of elders who exercised regularly revealed the strongest positive correlation with their exercise intensity by using Pearson correlation analysis. The results demonstrate that exercise-induced significant cortical activation in the elderly participants who exercised regularly, and most of the -values are less than 0.001. No significant correlation was observed between spectral power and exercise intensity in the elders who exercised occasionally. The young participants who exercised regularly had greater cardiac and neurobiological efficiency. Our results may provide a new exercise therapy reference for adult groups with different exercise habits, especially for the elders.

Does Lifelong Exercise Counteract Low-Grade Inflammation Associated with Aging? A Systematic Review and Meta-Analysis.
Sports Med

Medical Services, Real Madrid, Madrid, Spain.
Background: Aging is associated with sustained low-grade inflammation, which has been linked to age-related diseases and mortality. Long-term exercise programs have been shown to be effective to for attenuating this process; however, subsequent detraining might negate some of these benefits. Master athletes, as a model of lifelong consistent exercise practice, have been suggested to present similar inflammatory profiles to untrained young adults.

Physical activity (PA) and sedentary behavior (SB) are associated with affective feeling states in older adults, though the strength and direction of associations vary. This study used the Ecological Momentary Assessment (EMA) to determine how habit strength affects affective responses to movement behaviors. Older adults completed a 4-day EMA protocol with 10 randomly delivered, smartphone assessments per day while simultaneously wearing two activity monitors recording PA and SB.

Background: Previous studies show that ketosis caused by the consumption of low-carbohydrate diets improves cognitive functions and that ketogenic diets can be used to treat epilepsy. In vivo and in vitro experiments have shown that ketosis regulates pain, inflammation, and oxidative stress. Thus, we investigated the effects of ketosis induced by a low-carbohydrate diet on muscle soreness, inflammation, and redox status in human subjects.

The 25-question Geriatric Locomotive Function Scale (GLFS-25) is a tool to identify locomotive syndrome, however, this tool is associated with the problem of a low complete response rate. We conducted this cross-sectional study of 2,474 community-dwelling residents to investigate the clinical characteristics of individuals who are prone to provide incomplete responses to the GLFS-25 questionnaire. The participants were divided into the following four groups based on the number of the GLFS-25 items they answered: 0 (n=279), 1-21 (n=36), 22-24 (n=273), and 25 (n=1,886).
