    Abstract: Physical exercise has been shown to improve balance, gait, and cognitive function in older adults. Interactive cognitive-motor training (ICMT) combines physical exercise and cognitive stimulation, but few studies have focused on the effect of ICMT on static and dynamic balance in older adults. This study aims to improve the balance of older adults to reduce fall-related injuries for sustainable development goals. We randomly assigned 38 older adults to either the ICMT group (n = 22) or the control group (n = 16). The ICMT group participated in 60-min exercise sessions three times a week for 12 weeks, while the control group maintained their regular activities. The static and dynamic balances were assessed before and after the intervention. The results indicated the ICMT group demonstrated significant improvements in static balance, specifically in swing path and velocity (V) in the medial-lateral (M-L) direction with eyes open (p 〈 0.05). With eyes closed, the ICMT group showed significant improvements in total swing path and area compared to the control group (p 〈 0.05). In dynamic balance, there was a significant difference in the lateral (L) angle limit of stability (LOS) between the ICMT group and the control group (p 〈 0.05). In conclusion, ICMT effectively enhances static balance and maintains dynamic balance in older adults.

    Abstract: Background: As the population ages, cognitive impairment and dementia have become one of the greatest health threats in older adults. Prior studies suggest that exergaming could improve cognitive function in older adults. To date, few long-term exergames intervention studies on older adults during the COVID-19 epidemic exist. This study aimed to investigate the effects of exergame on cognitive function in Chinese older adults, and to examine whether exergame was more effective than aerobic dancing for executive function and working memory. Methods: 55 participants (mean age = 65.4 ± 3.7 years) were randomly assigned to an exergame training (ET) group, an aerobic dancing training (ADT) group, or a control (CON) group. The ET and ADT groups received 36 sessions (three 75-min training sessions per week, exercise intensity = 65 to 75% HRmax) during a 12-week period. The outcome measures for cognitive function included working memory measured by the N-back test, and executive function measured by the Stroop test. Results: The ET group showed a significantly positive effect in working memory, relative to the ADT (accuracy in 1-back test: ES = 0.76, p 〈 0.01), and CON group (accuracy in 1-back test: ES = 0.87, p = 0.02). Moreover, the performance in the Stroop test showed some improvements in executive function after intervention in the ET and ADT groups (Stroop intervention effect: ES = 0.38; p = 0.25). Conclusions: Exergame had a positive benefit in improving cognitive functions in older adults without cognitive impairment. Long-term exergame training could improve working memory in older adults. Exergame and aerobic dancing can efficiently improve inhibitory control of executive function in older adults. Maintaining an active lifestyle is protective of cognitive health in older adults.

    Abstract: Background: Research shows physical activity (PA) is negatively associated with refractive error, especially outdoor activity. Our study aimed to examine the association of PA levels and sedentary time (SED) with refractive error in boys and girls living in urban and rural areas. Methods: A total of 8506 urban/rural boys and girls (13.5 ± 2.8 years old) in Shaanxi Province, China participated in this study. Questions about PA, SED, outdoor exercises, and digital screen time were asked in the study survey. Non-cycloplegic refractive error was measured by an autorefractor. The differences between sex/area groups have been analyzed by one-way ANOVA. The association of PA/SED with spherical equivalent (SE) and cylinder power was analyzed by general linear regression. The association between PA/SED and the risk of refractive error was determined using the binary logistic regression model. Results: Of the 8506 participants, the prevalence of refractive error was significantly higher in girls and urban students (p 〈 0.05). Less SED and digital screen time, and more outdoor activity were significantly associated with SE (p 〈 0.05), respectively. More PA and less SED were significantly associated with lower cylinder power (p 〈 0.05), respectively. More PA and less SED were significantly associated with lower risks of myopia and astigmatism, respectively (p 〈 0.05). Conclusions: PA and SED were associated with the risk of refractive error. Maintaining a healthy lifestyle can help to reduce the risk of refractive error in boys and girls.

    Abstract: Research Highlights: Intensive nitrogen (N) application for agricultural purposes has substantially increased soil nitrous oxide (N2O) emissions. Agricultural soil has great potential in the reduction of N2O emissions, and applications of biochar and nitrification inhibitors may be useful for mitigating agricultural soil N2O emissions. Background and Objectives: Camellia oleifera Abel. is an important woody oil plant in China. However, intensive N input in C. oleifera silviculture has increased the risk of soil N2O emissions. As an important greenhouse gas, N2O is characterized by a global warming potential at a 100-year scale that is 265 times that of carbon dioxide. Thus, mitigation of soil N2O emissions, especially fertilized soils, will be crucial for reducing climate change. Materials and Methods: Here, we conducted an in situ study over 12 months to examine the effects of C. oleifera fruit shell-derived biochar and dicyandiamide (DCD) on soil N2O emissions from a C. oleifera field with intensive N application. Results: A three-fold increase of cumulative soil N2O emissions was observed following N application. Cumulative N2O emissions from the field with N fertilization were reduced by 36% and 44% with biochar and DCD, respectively. While N2O emissions were slightly deceased by biochar, the decrease was comparable to that by DCD. Conclusions: Results indicated that biochar may mitigate soil N2O emissions substantially and similarly to DCD under specific conditions. This result should be examined by prolonged and multi-site studies before it can be generalized to broader scales.
