《Sport Management Review》2019,22(4):513-526
Researchers examining carbon dioxide-equivalent emissions (carbon footprint) in sport have focused on sport events and, to a lesser extent, sport teams, but provided only average or aggregate values. The author takes the perspective of active sport participants and considers the heterogeneity of individual sport participation behavior. Using online surveys, adult active sport participants (n = 6537) in 20 different sports with main residence in Germany were asked to report their sport-travel behavior in 2015, including traveling in the context of regular (weekly) activity, sport competitions/tournaments, league games, day trips, and training camps/vacations. Annual carbon footprints were estimated using information about travel distances and transportation means. The results revealed an average annual carbon footprint of 844 kg of carbon dioxide-equivalent emissions, with individual sports producing more emissions than team/racket sports. Participants in nature sports had the highest emission levels. Regression analyses revealed that environmental consciousness significantly reduced carbon footprint in individual sports, but not in team/racket and nature sports, supporting the existence of an environmental value-action gap. Activity years, club membership, weekly exercise hours, performance level, and income were mainly positively associated with annual carbon footprint, while gender was insignificant. The findings have implications for policy makers and managers in sport associations and clubs.  相似文献

Given sport has been largely absent from U.S. public health policies and discourse, the author suggests ways that sport can be better managed to promote health. Using a critical perspective and grounded theory approach, the author examined the experiences of 14 men in the grassroots recreational program, F3. Data were collected through observation and semi-structured interviews. Based on the results, a conceptual model that suggests how sport should be managed to address illnesses related to physical inactivity is put forth. The resulting Sport as Medicine model indicates that Creating a Team Structure, Providing a Place to Be Accountable, and Ensuring No One is Left Out, led to meaningful Health Outcomes, including Physical Health, Mental Toughness, and Social Connections. As the distinctiveness of sport continues to emerge, the author provides a framework to consider how sport can be part of public health efforts to address physical inactivity. Thus, this work positions sport as medicine by pinpointing how sport can be managed so that holistic health outcomes are more likely achieved.  相似文献

运用问卷调查法和数理统计法,对176名大学生及其父母的饮食、身体活动及教养方式进行调查分析。结果显示,子女同父母在体重指数(BMI)上具有显著正相关关系(r=19,P<05),而在每周平均身体活动量上无显著相关(r=08,P=17)。回归分析表明,三类教养方式对子女BMI均无直接预测作用,然而专制型父母教养方式对父母与子女BMI的相关关系起间接调节作用(P<01);在子女身体活动行为方面,溺爱型父母教养方式更有可能导致子女的身体活动不足(P<01)。研究结果表明,大学生离开家庭环境后,父母教养方式仍然对子女BMI和身体活动行为产生持续影响,父母与子女BMI方面存在相关关系。为今后在青少年肥胖干预及身体活动促进研究中纳入教养方式因素提供了实证依据。  相似文献

PurposeThe aim of this study was to evaluate the efficacy of a 17-week, 3-component lifestyle intervention for enhancing health behaviors during the coronavirus disease 2019 (COVID-19) pandemic.MethodsA parallel-group (intervention and control) study was conducted amongst 79 airline pilots over a 17-week period during the COVID-19 pandemic. The intervention group (n = 38) received a personalized sleep, dietary, and physical activity (PA) program. The control group (n = 41) received no intervention. Outcome measures for sleep, fruit and vegetable intake, PA, and subjective health were measured though an online survey before and after the 17-week period. The changes in outcome measures were used to determine the efficacy of the intervention.ResultsSignificant main effects for time × group were found for International Physical Activity Questionnaire-walk (p = 0.02) and for all other outcome measures (p < 0.01). The intervention group significantly improved in sleep duration (p < 0.01; d = 1.35), Pittsburgh Sleep Quality Index score (p < 0.01; d = 1.14), moderate-to-vigorous PA (p < 0.01; d = 1.44), fruit and vegetable intake (p < 0.01; d = 2.09), Short Form 12v2 physical score (p < 0.01; d = 1.52), and Short Form 12v2 mental score (p < 0.01; d = 2.09). The control group showed significant negative change for sleep duration, Pittsburgh Sleep Quality Index score, and Short Form 12v2 mental score (p < 0.01).ConclusionResults provide preliminary evidence that a 3-component healthy sleep, eating, and PA intervention elicit improvements in health behaviors and perceived subjective health in pilots and may improve quality of life during an unprecedented global pandemic.  相似文献

镉锌交互作用对玉米幼苗生理生化特性的影响   总被引:6,自引:0,他引:6  
刘建新 《宜春学院学报》2004,26(6):55-57,60
以不同浓度的镉(Cd2 )、锌(Zn2 )处理玉米,研究CA、Zn单一及复合污染对幼苗生长及生理生化特性的影响.结果表明,随着Cd2 、Zn2 浓度的增加,CA、Zn单一及复合处理的根长,株高、根和地上部干重减少;根内丙二醛(MDA)积累增加,根系活力和叶片硝酸还原酶活性下降,叶绿素含量降低,Cd、Zn交互作用显示出协同作用的趋势。  相似文献
