Heart rate variability, psychological variables, and executive performance in teachers: An exploratory cross-sectional study
Objective Teaching is a high-demand occupation in which sustained stress may impair wellbeing and self-regulatory processes. Within the neurovisceral integration framework, heart rate variability (HRV) is used as an indicator of autonomic modulation relevant to self-control. To examine the relationships among perceived stress, social support, resting HRV, and executive function performance (Stroop and verbal fluency) in teachers, considering burn…
Brief mind–body exercise in high-latitude aging: Reduced sedentarism and domain-specific cognitive/social benefits
Objective Older adults living at high southern latitudes face compounded barriers to mobility and social participation due to cold, wind, and seasonality. Visuospatial–executive functions, which support everyday tasks such as route finding, dual-task walking, and planning in older adults, are particularly vulnerable to age-related decline after the seventh decade of life. Low-dose, climate-adapted mind–body exercise (MBE), delivered once weekly i…
Sensory processing sensitivity, anxiety, and short-term heart rate variability in older adults living at high southern latitudes: A brief report
In older adults living at high southern latitudes, SPS appears to be associated with anxiety but not to conventional short-term HRV markers, suggesting SPS may reflects psychological vulnerability rather than parasympathetic dysfunction detectable with brief HRV recordings. These findings highlight the need for context-aware mental-health strategies for highly sensitive older adults in understudied southern populations
The winter is coming: Seasonal variations in BDNF levels among older adults in a high-latitude region — a preliminary study
In this small longitudinal cohort, winter was associated with a reduction in plasma BDNF in older adults, independent of baseline cognition and anxiety. These results require replication in larger samples
Validity and Reliability of Short-Term Heart Rate Variability Parameters in Older People in Response to Physical Exercise
Our results provide moderate to strong evidence for using HRV to measure cardiac autonomic response to moderate exercise, suggesting that it is sufficiently reliable to show similar results to those shown in this test-retest protocol
Physical Activity, Seasonal Sensitivity and Psychological Well-Being of People of Different Age Groups Living in Extreme Environments
Physical activity can prevent many organic and mental pathologies. For people living in extreme southern high-latitude environments, weather conditions can affect these activities, altering their psychological well-being and favoring the prevalence of seasonal sensitivity (SS). This study aims to determine the relationships between the practice of physical activity, seasonal sensitivity and well-being in people living in high southern latitudes. …
Effectiveness of elastic band training and group-based dance on physical-functional performance in older women with sarcopenia: A pilot study
Elastic band training produces significantly greater responses on physical-functional performance regarding group-based dance in older women with sarcopenia. On the other hand, the EBG revealed a significant improvement in fat-free mass and upper and lower limb muscle strength, as well as a significant decrease time in TUG, and walking speed. Elastic band exercise is a safe, easy, affordable, and effective physical activity strategy, according to…
Factors Associated with Poor Health-Related Quality of Life in Physically Active Older People
This study aimed to associate morphological variables and physical fitness with health-related quality of life (HRQoL) in physically active older people. A cross-sectional study was carried out that evaluated 470 older people (89.57% female) with a mean age of 70.13 ± 6.57 years, residing in two regions of Chile. Morphological variables (body weight, bipedal height, waist circumference, body mass index, and waist to height ratio), physical fitnes…
