Molecular hydrogen is a promising therapeutic agent for pulmonary disease     

Zhiling FU  Jin ZHANG 《Journal of Zhejiang University. Science. B》2022,23(2):102

Molecular hydrogen exerts biological effects on nearly all organs. It has anti-oxidative, anti-inflammatory, and anti-aging effects and contributes to the regulation of autophagy and cell death. As the primary organ for gas exchange, the lungs are constantly exposed to various harmful environmental irritants. Short- or long-term exposure to these harmful substances often results in lung injury, causing respiratory and lung diseases. Acute and chronic respiratory diseases have high rates of morbidity and mortality and have become a major public health concern worldwide. For example, coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a global pandemic. An increasing number of studies have revealed that hydrogen may protect the lungs from diverse diseases, including acute lung injury, chronic obstructive pulmonary disease, asthma, lung cancer, pulmonary arterial hypertension, and pulmonary fibrosis. In this review, we highlight the multiple functions of hydrogen and the mechanisms underlying its protective effects in various lung diseases, with a focus on its roles in disease pathogenesis and clinical significance.  相似文献   

生态文明：城市休闲体育发展的必然选择     

单凤霞  郭修金 《南京体育学院学报(社会科学版)》2019,2(1):60-68

“美丽中国”战略目标的实现离不开“美丽城市”的建设。生态文明是实现美丽城市更新建设的保证者,而美丽城市的建设是落实生态文明的重要举措,两者互动发展、共同促进。城市休闲体育的蓬勃开展离不开生态文明的推动与滋养,生态文明建设是休闲体育发展的至高境界,为城市休闲体育发展提供了外在环境和内部动力。城市休闲体育通过亲近自然、绿色消费、健身怡情、协调“三生”等实际行动,起到了推动人居环境改善、拉动低碳经济增长、实现生命价值延展和促进城市休闲功能提升的作用,是生态文明建设的最佳践行手段。  相似文献   

Compensatory changes in physical activity and sedentary time in children and adolescents with cystic fibrosis     

Kelly A. Mackintosh  Nicola D. Ridgers  Melitta A. McNarry 《Journal of sports sciences》2019,37(13):1506-1511

Physical activity (PA) is a key element in Cystic Fibrosis (CF) treatment strategies, yet little is known as to whether activity compensation occurs. This study examined whether PA and/or sedentary time on one day were temporally associated with time spent in these intensities the following day in youth with CF. Time spent sedentary and in different PA intensities were objectively-measured for seven consecutive days in 50 youth (22 boys; 12.0 ± 2.7 years); 25 with mild-to-moderate CF and 25 age- and sex-matched controls. Multilevel analyses (day and child) were conducted using generalised linear latent and mixed models. On any given day, every additional 10 minutes spent in sedentary time or moderate-to-vigorous physical activity (MVPA) were associated with 1.9 (95%CI: ?3.6 to ?1.2) and 12.4 (95%CI: ?22.1 to ?2.9) minutes less sedentary time the following day, respectively. These temporal associations were also observed when split by group (3.1 vs. 1.9 minutes for healthy and CF, respectively). These findings indicate that youth do not compensate their PA, irrespective of disease status, between days, but may compensate their sedentary time between days. Experimental studies are warranted to fully elucidate whether compensatory responses to PA and sedentary time occur, which is fundamental for informing PA promotion strategies.  相似文献   

竞技游泳运动员运动性伤病情况调查分析          下载免费PDF全文

檀志宗  楼俊华  李男 《体育科研》2019,(6):93-97

采用问卷调查法对浙沪两省市194名游泳运动员进行运动性伤病调查,主要从运动性伤病的类型、部位、性质方面对比分析不同竞技水平游泳运动员的伤病表型特征。结果显示：优秀运动员运动性损伤较常见,多以慢性劳损为主,损伤部位依次为肩关节、腰背部和膝关节;一般运动员常发生急性损伤,损伤部位依次为膝关节、肩关节和腰背部。两组运动员鼻炎和中耳炎均常见。因此,依据运动性伤病的可能原因与机制,需要制定有针对性的预防措施,以减少运动性伤病的发生。  相似文献   

The influence of race length on arterial compliance following an ultra-endurance marathon     

Alis Bonsignore  Shannon S. D. Bredin  Holly Wollmann  Barb Morrison  Andrew Jeklin  Lauren Buschmann 《European Journal of Sport Science》2017,17(4):441-446

There is inconclusive evidence concerning the effects of routine participation in ultra-endurance events on cardiovascular disease (CVD) risk. Arterial compliance is a reliable, non-invasive, and effective tool for evaluating CVD risk. The purpose of this research was to examine if race length influences acute changes in arterial compliance following an ultra-marathon event. A total of 46 ultra-marathon runners were recruited including 21 participants (39.8?±?8.3?years, 6 females) in the 80-km event and 25 participants (43.7?±?9.8?years, 3 female) in the 195-km event. Arterial compliance was measured via radial applanation tonometry (CR-2000, HDI) for diastolic pulse contour analysis before and following the race. Significant between-group differences were found for changes in large arterial compliance with a decrease (increase in stiffness) following the 195-km event and an increase following the 80-kilometre event (p?<?.05). Longer race lengths are associated with greater reductions in large arterial compliance following recreational ultra-marathon running. Assessment of arterial compliance might be a useful prognostic tool to assess the long-term risk of CVD among ultra-marathon runners.  相似文献   

生活方式干预对心血管疾病危险因素的影响——美国HELPS项目成果     

Peter H. Brubaker  罗曦娟  Chelsea Boltj  Shuchang Du 《北京体育大学学报》2017,40(6):48-53

摘要：心血管疾病（CVD）一直是全世界最主要的死因。由于CVD等慢性疾病对健康的威胁越来越大,有必要开展生活方式干预项目以控制这些疾病的危险因素。本研究的目的是评估美国的重要慢病干预项目—HELPS治疗型生活方式改变（TLC）项目对减少CVD危险因素和其他慢性疾病的有效性。方法：140位大学教职工参加为期12周的HELPS TLC项目,干预前后用配对t检验对其体重、BMI、腰围（WC）、6分钟步行距离（6MWD）、空腹血脂和血糖进行测定和比较。结果：干预后6MWD显著增加,总胆固醇（TC）和WC显著下降。对“高危”参与者进一步分析显示：BMI（-1.5±0.5,-3.9%）、TC（- 22.8±4.0,-9.0%）、LDL（- 14.1±4.9,9.3%）和血糖（-6.9±2.2,-6.1%）均显著下降;男性腰围（-4.5±0.8,-10%）显著减小,女性未见显著改变（-1.5±0.5,-4.0%）。此外,体重的变化与TC（r=0.43）、LDL（r=0.35）和血糖（r=0.44）的变化均显著相关。结论：参加12周的生活方式干预项目可以使CVD危险因素减少,特别是在CVD“高危”个体中。HELPS TLC项目的远期效果还待进一步深入研究。  相似文献
