*** There is a growing body of research supporting the idea that a plethora of health benefits can result from resistance training using a low volume,high-effort approach(e.g.,increased metabolic rate and bone mineral density,a reduction in blood pressure,and improved muscle quality and insulin sensitivity,among ***,muscular strength and muscle massprimary goals and benefits of participation in resistance trainingare independently strong predictors of longevity and quality of life. Thus,many have sought to identify how the manipulation of resistance training variables might lead to“optimal”adaptations in such outcomes,as evidenced by repeated attempts over recent decades to review the literature and provide consensus statements on this topic.5-10 One variable that is often hotly debated within resistance training is training to failure.

It has been known for some time that strain injuries occur through the excessive lengthening of a muscle.^(1–3)However,the precise mechanism for strain injury remains elusive and has been the subject of recent debate in the Journal of Sport and Health Science,^(4–9)but it seems sensible to consider mechanisms at the level of the muscle *** was previously believed that damage was the result of non-uniform stretching of

Purpose:The aim of this mixed-studies systematic review was to ascertain the effectiveness of school-based interventions in increasing physical activity(PA) and/or reducing sedentary time(ST) in children aged 5-11 years,as well as to explore their effectiveness in relation to categories of the theory of expanded,extended,and enhanced opportunity(TEO).Methods:Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA) guidelines,5 databases were searched using predefined search *** title and abstract screening of 1115 records,the removal of duplicates(n=584) and articles that did not meet the inclusion criteria agreed to a priori(n=419) resulted in 112 records that were full-text *** independent reviewers subsequently used the mixed-methods appraisal tool to assess the methodological quality of 57 full-text studies that met the inclusion criteria after full-text *** interventions were summarised using the TIDierR checklist and *** strength of evidence was determined using a 5-level rating system utilising a published decision ***:Overall evidence ratings for interventions implemented within school settings were:no evidence of effects on moderate-to-vigorous physical activity(MVPA) and inconclusive evidence of effects on sedentary *** relation to the TEO,expansion of PA appeared to be the most promising intervention type for MVPA,with moderate evidence of effect,whereas extension and enhancement of PA opportunity demonstrated no evidence of effect.A critical issue of possible compensatory behavior was identified by analysis of intervention effect in relation to PA measurement duration;when studies measured changes in PA during the actual intervention,there was moderate evidence of effect,whereas those that measured changes in PA during the school day presented inconclusive evidence of effect,and those that measured changes in PA over a whole day yielded no evidence of *** meta-analys

目的调查在全口义齿随访患者中，总义齿戴用时间（CDs）与口腔健康相关的生活质量（OHRQoL）之间的相关性。材料和方法应用德国版的LI腔健康影响程度量表（OHIP-G）测量总义齿戴牙2到51个月后仍保持复诊的50名无牙颌患者（平均年龄±标准差：72．5＋9．4；年龄范围：52—91岁，66％为女性）的OHRQoL。研究的结果是OHIP—G各项的和（OHIP—G49；范围0—196）反映了有特征性的OHRQoL。自变量有（1）戴用第一付总义齿至今的时间，（2）之前所戴用过的总义齿的数目，（3）现有总义齿戴用的时间，和（4）戴用第一付总义齿时的年龄。在控制了年龄因素影响的前提下，应用ordinary least—square回归分析研究自变量与结果之间的联系。结果现有总义齿戴用的时间，戴用第一付总义齿至今的时间，之前所戴用过的总义齿的数目和戴用第一付总义齿时的年龄并不显著影响OHRQoL。每个自变量的回归系数分别为O．0，95％CI：-0．1到0．2；00．1，95％CI：-O．4到0．3；0．8，95％CI：-1．5到3．0；和0．4，95％CI：-0．1到0．8。结论在戴用总义齿并保持复诊的患者中，对口腔内无法避免的与无牙颌、义齿戴用、年龄和其他因素相关的解剖学和生物学变化的反应，不会必然地迅速转化为明显的口腔健康的变化。
