If we built it,would they come? Creating instruction videos with promotion in mind     

Leticia Camacho 《Journal of Business & Finance Librarianship》2018,23(1):26-34

This article reports on a video project done in an academic library where faculty were included in the production and marketing of the library instruction videos. The videos allowed the librarian to provide a shorter presentation and spend most of her time working individually with each student. The results showed that 97% of the students watched the videos and were able to benefit from the content. The implementation of the videos was a success due to the collaboration of the professors teaching the three courses and the buy-in of the course coordinator; both factors were essential in the success of the video project.  相似文献   

Childhood Physical Fitness and Performance as Predictors of High School Sport Participation

ABSTRACT

Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school.  相似文献   

Effects of a kindergarten-based,family-involved intervention on motor performance ability in 3- to 6-year-old children: the ToyBox-study

This study targeted to examine the effect of the ToyBox-intervention, a kindergarten-based, family-involved intervention, aiming to improve preschooler’s energy-related behaviours (e.g., physical activity) on motor performance ability. Physical activity sessions, classroom activities, environmental changes and tools for parents were the components of the 1-year intervention. The intervention and control were cluster-randomised, and children’s anthropometry and two motor test items (jumping from side to side, JSS and standing long jump, SLJ) were assessed. A total of 1293 (4.6 ± 0.69 years; 52% boys) from 45 kindergartens in Germany were included (intervention, n = 863; control, n = 430). The effect was assessed using generalised estimating equation. The intervention group showed a better improvement in JSS (Estimate 2.19 jumps, P = 0.01) and tended to improve better in SLJ (Estimate 2.73 cm, P = 0.08). The intervention was more effective in boys with respect to SLJ (P of interaction effect = 0.01). Children aged <4.5 years did not show a significant benefit while older children improved (JSS, Estimate 3.38 jumps, P = 0.004; SLJ, Estimate 4.18 cm, P = 0.04). Children with low socio-economic status improved in JSS (Estimate 5.98 jumps, P = 0.0001). The ToyBox-intervention offers an effective strategy to improve specific components of motor performance ability in early childhood. Future programmes should consider additional strategies specifically targeting girls and younger aged children.

大学生涉跑猝死事件的体医融合防卫机制研究     

洪邦辉  胡庆山  张恒波  向彪 《武汉体育学院学报》2020,54(2):32-36,58

近年来，大学生身体素质不佳，已成为"老大难"，也是刻不容缓需要解决的问题，多地曾出现在体测、运动会、马拉松中晕倒甚至猝死事件，这给学校体育工作的开展带来不小的考验。带着因涉跑引起猝死的疑问，通过猝死案例分析，探究高校大学生猝死的病理学的非运动成因。研究认为：涉跑猝死的主因是先天性生理疾病，运动不是引发猝死的主要诱因，并提出了预防运动猝死的"堵疏结合"的医学监控策略和体医融合防卫机制构建方法。建议通过入校时医学筛查、跑前医学检查、跑中医学观察、猝死现场急救、跑后跟踪复查降低猝死风险；建立宿舍、运动场地、运动项目的全覆盖的心脏复苏志愿队伍，实施"黄金8分钟"内的急救生存链；建立学生、学校、政府、社会四方体育运动分级分类保险制度，从风险转移和人道主义援助进行关怀；建立涉跑猝死、猝死、非正常死亡的数据库，开展非正常死亡人员的病理学研究；建立全生命周期医学监控和健康安全宣传教育，形成全方位、全过程、全人员的体医融合防卫机制。  相似文献   

Effectiveness of physical education to promote motor competence in primary school children     

Vítor P. Lopes  David F. Stodden  Luis P. Rodrigues 《Physical Education & Sport Pedagogy》2017,22(6):589-602

Background: Motor skill (MS) competence is an important contributing factor for healthy development.

Purpose: The goal was to test the effectiveness of primary school physical education (PE) on MS and physical fitness (PF) development.

Methods: Three classes (n?=?60, aged 9.0?±?0.9) were randomly assigned to three diverse conditions during a school year: two PE lessons/week (PE-2), three PE lessons/week (PE-3), and no PE lessons control group (CG). BMI, skinfolds, PF (9-min run/walk, sit-up, modified pull-ups), gymnastics, soccer, handball, basketball and track-and-field skills were evaluated. Effect sizes (d) were reported as magnitude of change.

Results: Skinfolds significantly increased only in CG (d?=?1.21). PF composite z-scores improved in PE-3 (d?=?0.61), but decreased in PE-2 (d?=?0.57), and had no changes in CG. Statistically significant improvement was verified in gymnastics and handball skills in both experimental groups (gymnastic: d?=?2.95 and d?=?2.61 for PE-3 and PE-2, respectively; handball: d?=?1.87 and d?=?0.57 for PE-3 and PE-2, respectively), and no changes were seen in CG. In soccer, there were improvements only in the PE-3 (d?=?0.55), and in basketball only in PE-2 (d?=?0.46). There were no changes in any group for track-and-field skills.

Conclusions: PE programs can effectively promote PF and MS development.  相似文献

杨昆昊  夏赞宇  何芃  吴丽  龚玲玲  钱越英  侯琰霖  何裕建 《中国科学院大学学报》2017,34(3):304-317

采用GC-MS等仪器分析手段对北京市各主要品牌的燃油进行质量分析，并建立以静稳天气下单位体积中的污染物日均变化为相对参照标准计算各污染物贡献率的新思路。首先研究机动车尾气各主要污染物（CO、HC、NO₂和SO₂）在单位体积的日均排放量，然后分别统计北京市两年（2013年11月-2015年10月）大气中各对应污染物实测的单位体积的日均变化量，再分别计算出汽车尾气对大气各污染物的贡献率。结果如下。1）北京市燃油普遍存在重金属含量超标，硫含量超标，不饱和芳烃含量超标，氮含量偏高（无国标制约）等问题。2）在供暖季，北京市汽车尾气排放的CO、NO₂和SO₂分别占总CO、NO₂和SO₂排放的30.1%、72.4%和6.6%；在非供暖季，汽车尾气排放的CO、NO₂和SO₂分别占总CO、NO₂和SO₂排放的53.3%、74.3%和20.3%；北京市汽车HC排放全年平均分担率约为67.8%。研究结果表明，燃油是北京市大气污染的主要原因。最后为北京市大气污染的有效治理提出具体的建议和措施。  相似文献   

踢毽子动作发展序列特征研究及案例教学分析     

王兴泽 《北京体育大学学报》2016,39(11):89-96+118

摘要：为了发扬民族传统体育项目的健身锻炼功效、发挥中小学踢毽子活动的育人功能，以及科学探索不同年龄阶段健康个体在学习踢毽子动作时的典型动作特征。采用现代动作学科知识理论研究民族传统体育项目是传承传统文化的具体体现，也是实施体育育人的操作手段。梳理文献资料得出U6—14阶段健康个体典型的动作发展特征，即U6—7阶段的学习运用自我、U8—9阶段的基本动作过程学习、U10—11阶段的基本运动技能的学习和应用，以及U12—14阶段的基本动作技术向专门动作技术过渡。录像观察得出踢毽子活动的动作发展序列特征，即，整体发展序列的5个阶段和4个部位发展序列的不同阶段发展特征。案例教学实验分析了义务教育阶段体育与健康课程标准、教科书、教师用书中关于踢毽子课程设置的客观性，得出U6—7阶段和U10—11阶段踢毽子课程设置难度大。本文揭示了儿童、青少年踢毽子动作的学习与掌握不仅依赖于直接教学，更要关注儿童、青少年的发展；体现儿童、青少年对特定运动项目的学习特征是自然发展的，而不应是学习与训练促成的。  相似文献

Improved children’s motor learning of the basketball free shooting pattern by associating subjective error estimation and extrinsic feedback     

Leandro de Carvalho da Silva  Carla Ferro Pereira-Monfredini 《Journal of sports sciences》2017,35(18):1825-1830

This study aimed at assessing the interaction between subjective error estimation and frequency of extrinsic feedback in the learning of the basketball free shooting pattern by children. 10- to 12-year olds were assigned to 1 of 4 groups combining subjective error estimation and relative frequency of extrinsic feedback (33% × 100%). Analysis of performance was based on quality of movement pattern. Analysis showed superior learning of the group combining error estimation and 100% feedback frequency, both groups receiving feedback on 33% of trials achieved intermediate results, and the group combining no requirement of error estimation and 100% feedback frequency had the poorest learning. Our results show the benefit of subjective error estimation in association with high frequency of extrinsic feedback in children’s motor learning of a sport motor pattern.  相似文献   

Could Slackline Training Complement the FIFA 11+ Programme Regarding Training of Neuromuscular Control?     

Tobias Jäger  Julian Kiefer  Inge Werner 《European Journal of Sport Science》2017,17(8):1021-1028

The current study compared changes in neuromuscular control between slackline training and the stabilization training elements of the FIFA 11+ programme. Twenty-five students in 2 groups performed a 12-unit training programme. The slackline training group (n?=?13) exclusively trained with a slackline. The stabilization training group (n?=?12) practised exercises as described in the second part of the FIFA 11+ programme. Improvements in balance were assessed using three tests for dynamic, quasi-static, and perturbed postural control: the star excursion balance test (SEBT), the closed-eye single-leg stance, and the MFT S3-Check. Both groups significantly improved the stability and sensorimotor index of the MFT S3-Check (p?<?.001), their range on the SEBT (p?<?.001), and the duration of closed-eye single-leg stance (p?<?.001). The group?×?training interaction was significant for the MFT S3-Check (stability index: p?=?.042; sensorimotor index: p?=?.004) and the SEBT (dominant leg: p?=?.003; averaged both legs: p?=?.016), with the slackline training group showing a larger training effect than the stabilization training group. The results of the present study suggest that slackline training offers similar – or better – improvements in neuromuscular control as the FIFA 11+ warm-up programme. If compliance with the FIFA 11+ programme is declining, then slacklining might offer an alternative approach to reach the training goals of improved sensorimotor control.  相似文献
