ABSTRACT
Introduction: The global burden of age-related cognitive decline is increasing, with the number of people aged 60 and over expected to double by 2050. This study compares the acute effects of age-appropriate cognitively demanding aerobic exercises involving walking, on cognitive functions and exerkine responses such as brain-derived neurotrophic factor (BDNF) and cathepsin B (CTSB) in older, healthy adults. Methods/design: Healthy older golfers (n=25, 16 male and 9 female, 69±4 years) were enrolled in a 5-day randomised cross-over study and completed three different exercise trials (18-hole golf round, 6 km Nordic walking, 6 km walking) in a real-life environment, in random order and at a self-selected pace. Differences in cognition (the Trail-Making Test (TMT) AB) and exerkines (BDNF and CTSB) were analysed within groups using the Wilcoxon signed-rank test and between groups using the Kruskal-Wallis test. Results: All exercise types resulted in a significant decrease in the TMT A-test (p<0.05; golf: -4.43±1.5 s, Nordic walking: -4.63±1.6 s, walking: -6.75±2.26 s), where Nordic walking and walking demonstrated a decrease in the TMT B-test (p<0.05; Nordic walking: -9.62±7.2 s, walking: -7.55±3.2 s). In addition, all exercise types produced significant decreases in the TMT AB test scores (p<0.05), and Nordic walking (p=0.035) showed decreases in the TMTB-TMTA-test. There were no immediate postexercise changes in the levels of BDNF or CTSB. Conclusion: Acute bouts of golf, Nordic walking and walking improved cognitive functions irrespective of exerkines in healthy older adults. In addition, Nordic walking and walking in general enhanced executive functions. No significant effects were seen on the levels of BDNF and CTSB. Trial registration number: ISRCTN10007294.
ABSTRACT
Background and Aims: The COVID-19 pandemic was associated with reduced physical activity and increased sedentary behavior. Golf is a health-enhancing outdoor exercise and is associated with low risk of viral transmission. The purpose of this study was to describe the seasonal differences in physical activity and quality of life during the first wave of COVID-19 pandemic in 2020 in Finnish older golfers. Methods: Older golfers (n = 325) from eight golf clubs retrospectively responded to a questionnaire in summer 2020 on their physical activity and golf activity in winter 2019/20 (pre-COVID-19 winter season) and summer season 2020. In addition, they reported their quality of life after the first wave of pandemic in summer 2020. To evaluate the seasonal differences in physical activity, life quality and its association with golf activity, the data were analyzed using the Mann-Whitney U test, Wilcoxon signed-rank test, Spearman's correlation test, and linear regression analysis. Results: Despite COVID-19 restrictions, golfers' physical activity increased by 24% (p < 0.001) during the COVID-19 restrictions in the summer of 2020. Moderate physical activity increased by 37% (p < 0.001), walking activity increased by 26% (p < 0.001), and sitting decreased by 21% (p < 0.001) compared with the pre-COVID-19 winter season. The full 18-hole golf round activity was positively associated with moderate physical activity both in the summer and winter season, and with walking in the summer season. Over 90% of golfers reported good quality of life during the 2020 summer restrictions. Conclusion: In contrast to physical activity levels generally decreasing during the first wave of pandemic, physical activity levels in Finnish golfers increased, and these golfers reported a good quality of life. Golf can provide health enhancing physical activity and older golfers seems to be physically active throughout the year.
ABSTRACT
Objectives: The acute effects of aerobic exercise on cardiometabolic markers are well documented in younger healthy individuals, but the same effects in older adults have not been elucidated. As such, this study compares the acute effects of three different types of age-appropriate aerobic exercises on cardiometabolic markers. Methods: Healthy older golfers (n=25, 16 male and 9 female, 68±4 years) were enrolled in a randomised cross-over experiment. We compared the effects of three different acute aerobic exercises (18-hole golf, 6 km Nordic walk, 6 km walk) on blood pressure, blood glucose and blood lipid profile in a real-life environment. Results: In the between-group comparison, playing golf resulted in a difference in blood glucose (golf: 0.01±1.0 mmol/L, walk: 1.3±0.9 mmol/L, p<0.001) compared with walking and triglycerides (golf: 0.13±0.2 mmol/L, Nordic walk: 0.31±0.2 mmol/L, walk: 0.23±0.2 mmol, p=0.012) and high-density lipoprotein cholesterol (golf: 0.04±0.06 mmol/L, Nordic walk: -0.02±0.06 mmol/L, walk: -0.02±0.07 mmol/L, p=0.002) compared with Nordic walking and walking. In addition, all groups had significant decreases (p<0.001) in systolic blood pressure, and Nordic walking and walking also demonstrated a decrease in diastolic blood pressure (p<0.05). Conclusion: Acute bouts of aerobic exercise improved cardiovascular profile in healthy older adults. Despite the lower exercise intensity of golf, the longer duration and higher energy expenditure appeared to have a more positive effect on lipid profile and glucose metabolism compared with Nordic walking and walking.
