| 1 | Modeling the dose-response rate/associations between VO2max and self-reported Physical Activity Questionnaire in children and adolescents显示文摘Background'. This study sought to explore the dose—response rate/association between aerobic fitness (VC)2max) and self-reported physical activity(PA) and to assess whether this association varies by sex, age, and weight status.Methods. VO2max was assessed using the 20・m shuttle・run test. PA was assessed using the Physical Activity Questionnaire (PAQ) for Adolescents(aged > 11 years, PAQ-A) or for Children (aged <11 years, PAQ-C). The associations between V02raax and PAQ were analyzed using analysisof covariance (ANCOVA), adopting PAQ and PAQ2 as covariates but allowing the intercepts and slope parameters of PAQ and PAQ2 tovary with the categorical variables sex, age group, and weight status.Results: ANCOVA identified a curvilinear association between VO2max and PAQ, with positive linear PAQ terms that varied for both sex andweight status but with a negative PAQ2 term of —0.39 (95% confidence interval (CI): —0.57 to —0.21) that was common for all groups in regardto age, sex, and weight status. These curvilinear (inverted U) associations suggest that the benefits of increasing PA (same dose) on VO2max isgreater when children report lower levels of PA compared to children who report higher levels of PA. These dose-response rates were alsosteeper for boys and were steeper for lean children compared to overweight/obese children.Conclusion'. Health practitioners should be aware that encouraging greater PA (same dose) in inactive and underweight children will result ingreater gains in V02max (response) compared with their active and overweight/obese counterparts. | Alan M.Nevill Michael J.Duncan Gavin Sandercock | 2020 | Journal of Sport and Health Science2020，9，1： | 5 |

| 3 | Science and Technology Networks: A Helping Hand to Boost Implementation of the Sendai Framework for Disaster Risk Reduction 2015–2030?显示文摘The Sendai Framework for Disaster Risk Reduction 2015–2030 underlines the importance of Science and Technology(S&T) and S&T networks for effective disaster risk reduction(DRR). The knowledge of existing S&T networks and their exact role in DRR,however, is limited. This opinion piece initiates a discussion on the role of S&T networks in the implementation of the Sendai Framework. The article highlights that current practice is oriented towards a narrative that emphasizes the potential of S&T for DRR and stresses a collaborative approach delivered through networks. But a true understanding of whether and how S&T networks can mobilize and enable S&T for DRR is missing. We call for a review of existing S&T networks for DRR and the development of good practice guidelines on S&T networks for DRR. This review should include knowledge on how to overcome common challenges and maximize the benefits, along with a framework for successful evaluation of such networks.This knowledge would provide much needed guidance for existing and emerging networks. | Robert sakic Trogrlic Lydia Cumiskey Annisa Triyanti Melanie J.Duncan Nuha Eltinay Rick J.Hogeboom Mansi Jasuja Chinaporn Meechaiya Christina J.Pickering Virginia Murray | 2017 | International Journal of Disaster Risk Science2017，8，1： | 2 |
| 4 | Effect of different intensities of physical activity on cardiometabolic markers and vascular and cardiac function in adult rats fed with a high-fat high-carbohydrate diet显示文摘Background: Physical activity(PA) and diet are 2 lifestyle factors that affect cardiometabolic risk. However, data on how a high-fat highcarbohydrate(HFHC) diet influences the effect of different intensities of PA on cardiometabolic health and cardiovascular function in a controlled setting are yet to be fully established. This study investigated the effect of sedentary behavior, light-intensity training(LIT), and high-intensity interval training(HIIT) on cardiometabolic markers and vascular and cardiac function in HFHC-fed adult rats.Methods: Twelve-week-old Wistar rats were randomly allocated to 4 groups(12 rats/group): control(CTL), sedentary(SED), LIT, and HIIT.Biometric indices, glucose and lipid control, inflammatory and oxidative stress markers, vascular reactivity, and cardiac electrophysiology of the experimental groups were examined after 12 weeks of HFHC-diet feeding and PA interventions.Results: The SED group had slower cardiac conduction(p = 0.0426) and greater thoracic aortic contractile responses(p < 0.05) compared with the CTL group. The LIT group showed improved cardiac conduction compared with the SED group(p = 0.0003), and the HIIT group showed decreased mesenteric artery contractile responses compared with all other groups and improved endothelium-dependent mesenteric artery relaxation compared with the LIT group(both p < 0.05). The LIT and HIIT groups had lower visceral(p = 0.0057 for LIT, p = 0.0120 for HIIT)and epididymal fat(p < 0.0001 for LIT, p = 0.0002 for HIIT) compared with the CTL group.Conclusion: LIT induced positive adaptations on fat accumulation and cardiac conduction, and HIIT induced a positive effect on fat accumulation,mesenteric artery contraction, and endothelium-dependent relaxation. No other differences were observed between groups. These findings suggest that few positive health effects can be achieved through LIT and HIIT when consuming a chronic and sustained HFHC diet. | Romeo B.Batacan Jr Mitch J.Duncan Vincent J.Dalbo Geraldine L.Buitrago Andrew S.Fenning | 2018 | Journal of Sport and Health Science2018，7，1： | 2 |

| 7 | Affective responses to supervised 10-week programs of resistance exercise in older adults显示文摘Background:Resistance exercise has numerous,well-documented benefits on the health and functional performance of older adults.However,little information exists on the affective responses to resistance exercise in this population.As affective responses can predict continued exercise behavior,examining if and how they differ between resistance exercise intensities and frequencies in older adults may provide important data to improve resistance exercise prescription.Methods:We monitored the affective responses of older adults when performing high-velocity,low-load(HVLL)or low-velocity,high-load(LVHL)resistance exercise once or twice weekly.A total of 40 moderately to highly active,but resistance-exercise naïve,older adults(60-79 years)completed 1 of 4 randomly assigned progressive resistance exercise conditions:HVLL once weekly(HVLL1:n=10),HVLL twice weekly(HVLL2:n=10),LVHL once weekly(LVHL1:n=10),or LVHL twice weekly(LVHL2:n=10).The Physical Activity Affect Scale,Felt Arousal Scale,Feeling Scale,rating of perceived exertion,Visual Analog Scale,and the Physical Activity Enjoyment Scale were used to assess enjoyment and affective responses.Results:The results from Physical Activity Enjoyment Scale(out of 35)suggest that all exercise conditions were largely and similarly enjoyable to older adults(HVLL1:30.9±2.4;LVHL1:31.9±3.6;HVLL2:30.9±3.5;LVHL2:30.2±3.7)despite greater fatigue(p=0.033;ηp^2p=0.22)and perceived workload(p=0.042;ηp^2=0.20)in LVHL(results from Visual Analog Scale).Conclusion:Moderately to highly physically active older adults may tolerate higher intensities of resistance exercise performed once or twice weekly without experiencing a negative impact on enjoyment.However,the role that supervision and social interaction played in shaping the participants’responses is unclear. | Darren L.Richardson Michael J.Duncan Alfonso Jimenez Paul M.Juris Neil D.Clarke | 2020 | Journal of Sport and Health Science2020，9，6： | 1 |
| 8 | Acceptability,usefulness,and satisfaction with a web-based video-tailored physical activity intervention:The TaylorActive randomized controlled trial显示文摘Purpose:This study aimed to examine the usage,acceptability,usability,perceived usefulness,and satisfaction of a web-based video-tailored physical activity(PA)intervention(TaylorActive)in adults.Methods:In 2013-2014,501 Australian adults aged 18+years were randomized into a video-tailored intervention,text-tailored intervention,or control group.Over 3 months,the intervention groups received access to 8 sessions of personally tailored PA advice delivered via the TaylorActive website.Only the delivery method differed between the intervention groups:video-tailored vs.text-tailored.Google Analytics and telephone surveys conducted at post intervention(3 months)were used to assess intervention usage,acceptability,usability,perceived usefulness,and satisfaction.Quantitative and qualitative process data were analyzed using descriptive statistics and thematic content analysis.Results:Of 501 recruited adults,259 completed the 3-month post-intervention survey(52%retention).Overall,usage of the TaylorActive website with respect to number of website visits,intervention sessions,and action plans completed was modest in both the video-tailored(7.6士7.2 visits,mean±SD)and text-tailored(7.3±5.4 visits)groups with no significant between-group differences.The majority of participants in all groups used the TaylorActive website less than once in 2 weeks(66.7%video-tailored,62.7%text-tailored,87.5%control;p<0.001).Acceptability was rated mostly high in all groups and in some instances,significantly higher in the intervention groups compared to the control group(p<0.010).Usability was also rated high;mean Systems Usability Scores were 77.3(video-tailored),75.7(text-tailored),and 74.1(control)with no significant between-group differences.Perceived usefulness of the TaylorActive intervention was low,though mostly rated higher in the intervention groups compared to the control group(p<0.010).Satisfaction with the TaylorActive website was mixed.Participants in both intervention groups liked its ease of use,personalized feedback,and tracking of progress,but also found completing action plans and survey questions for each session repetitive and tedious.Conclusion:Providing personally tailored PA advice on its own(through either video or text)is likely insufficient to ensure good retention,usage,perceived usefulness,and satisfaction with a web-based PA intervention.Strategies to address this may include the incorporation of additional intervention components such as activity trackers,social interactions,gamification,as well as the use of advanced artificial intelligence and machine learning technologies to allow more personalized dialogue with participants. | Stephanie Schoeppe Mitch J.Duncan Ronald C.Plotnikoff W.Kerry Mummery Amanda Rebar Stephanie Alley Quyen To Camille E.Short Corneel Vandelanotte | 2022 | Journal of Sport and Health Science2022，11，2： | 0 |
| 9 | Associations between aerobic and muscle-strengthening physical activity,sleep duration,and risk of all-cause mortality:A prospective cohort study of 282,473 U.S.adults显示文摘Purpose:To examine the joint associations between meeting guidelines for physical activity(PA)and sleep duration and all-cause mortality risk among adults.Methods:Participants were adults(n=282,473)aged 18-84 years who participated in the 2004-2014 U.S.National Health Interview Survey.Mortality status was ascertained using the National Death Index through December 2015.Self-reported PA(Active:meeting both aerobic(AER)and muscle-strengthening(MSA)guidelines,AER only(AER),MSA only(MSA),or not meeting either AER or MSA(Inactive))and sleep duration(Short,recommended(Rec),or Long)were classified according to guidelines,and 12 PA-sleep categories were derived.Adjusted hazard ratios and 95%confidence intervals(95%CIs)for all-cause mortality risk were estimated using Cox proportional hazards regression models.Results:A total of 282,473 participants(55%females)were included;18,793 deaths(6.7%)occurred over an average follow-up of 5.4 years.Relative to the Active-Rec group,all other PA-sleep groups were associated with increased mortality risk except for the Active-Short group(hazard ratio=1.08;95%CI:0.92-1.26).The combination of long sleep with either MSA or Inactive appeared to be synergistic.For a given sleep duration,mortality risk progressively increased among participants classified as AER,MSA,and Inactive.Within each activity level,the mortality risk was greatest among adults with long sleep.Conclusion:Relative to adults meeting guidelines for both PA and sleep duration,adults who failed to meet guidelines for both AER and muscle strengthening PA and who also failed to meet sleep duration guidelines had elevated all-cause mortality risks.These results support interventions targeting both PA and sleep duration to reduce mortality risk. | Mitch J.Duncan Stina Oftedal Christopher E Kline Ronald C.Plotnikoff Elizabeth G.Holliday | 2023 | Journal of Sport and Health Science2023，12，1： | 0 |
