This is so contemporary? Mediums of exchange and conservation     

Robert Lazarus Lane  Jessye Wdowin-McGregor 《文物保护研究》2016,61(3):104-108

What conservation strategies can be used for Tino Sehgal's 2005 work This Is So Contemporary, and what are their relations to oral traditions? Sehgal's art leaves no material traces, as the artist resists the use of photos and videos acting as a documentary surrogate for his work. This paper will explore how Sehgal's non-written documentation strategies connect to the work of Yumutjin Wunungmurra, a contemporary artist and ceremonial leader from Northeast Arnhem Land, Australia. The connection will be tracked through the role of caretaker and custodian that features in the workflow of both artists. The paper asks whether the performance-based strategies discussed can support the notion of conservation as a social process with multiple stakeholders.  相似文献

建筑物致人损害责任主体的确认     

赵献春 《张家口职业技术学院学报》2002,15(4):16-17,25

建筑物致人损害的责任主体是人，而不是物，并且是负有管理义务的人。在司法审判实践中，应区别不同情况来确定建筑物致人损害的责任主体，主要分为管理人有管理义务和管理人无管理义务两种情况。  相似文献

体育院校冰上运动对男大学生身体成分和骨密度的影响     

赵文艳 《冰雪运动》2016,(1):78-82

为探讨冰上运动项目对男大学生身体成分和骨密度的影响,采用韩国ZEUS9.9身体成分分析仪和法国Osteospace MEDI LINK超声骨量测量仪,分别对体育院校2010～2012级冰上运动专项的男大学生和没有运动专项的男大学生进行身体成分和骨密度的测量,并对实验数据进行统计学的分析与比较。结果显示,冰上运动专项男大学生左右腿肌肉含量、基础代谢率显著高于对照组（P＜0.05）,骨密度显著低于对照组大学生（P＜0.05）,这可能与调查对象的生活方式、饮食习惯、训练年限、运动水平以及冰上运动项目的教学内容有关。建议冰上运动专项男大学生改变不良生活方式、均衡饮食,适当调整运动训练方案,加强下肢的力量训练,提高运动成绩。  相似文献

Multiple components of fitness improved among overweight and obese adolescents following a community-based lifestyle intervention     

Erin K. Howie  Joanne A. McVeigh  Rebecca A. Abbott  Tim S. Olds  Leon M. Straker 《Journal of sports sciences》2016,34(16):1581-1587

Fitness is an important component of health, and obese adolescents regularly have poor fitness. Unfortunately, few have assessed the impact of community-based lifestyle interventions on multiple components of fitness. The purpose of this study was to assess the impact of participation in a community-based intervention involving adolescents and parents on multiple components of fitness of obese adolescents. In a within-subject, waitlist controlled clinical trial with 12 months follow-up in Western Australia, participants (n = 56) completed multiple fitness measures at baseline, immediately prior to beginning an 8-week intervention and at 3, 6 and 12 months during a maintenance period. Performance on the shuttle walk was improved immediately post-intervention (increase of 42.8 m, 95% CI: 7.5, 78.2) and at 12 months post-intervention (increase of 44.6 m, 95% CI: 1.3, 87.8) compared with pre-intervention. Muscle performance of quadriceps and deltoids were improved post-intervention (increase of 1.1 (95% CI: 0.1, 2.1) kg · F and 1.0 (0.02, 2.1) kg · F, respectively) and all muscle performance measures were improved at 12 months following the intervention. There were no changes in waist circumference. A community-based lifestyle programme such as Curtin University’s Activity, Food and Attitudes Program (CAFAP) may be a viable strategy for improving fitness in overweight adolescents.  相似文献   

Effects of interval aerobic training combined with strength exercise on body composition,glycaemic and lipid profile and aerobic capacity of obese rats     

Irene Coll-Risco  Virginia A. Aparicio  Elena Nebot  Daniel Camiletti-Moirón  Rosario Martínez  Garyfallia Kapravelou 《Journal of sports sciences》2016,34(15):1452-1460

The purpose of this study was to investigate the effects of interval aerobic training combined with strength exercise in the same training session on body composition, and glycaemic and lipid profile in obese rats. Sixteen lean Zucker rats and sixteen obese Zucker rats were randomly divided into exercise and sedentary subgroups (4 groups, n = 8). Exercise consisted of interval aerobic training combined with strength exercise in the same training session. The animals trained 60 min/day, 5 days/week for 8 weeks. Body composition, lipid and glycaemic profiles and inflammatory markers were assessed.

Results showed that fat mass was reduced in both lean and obese rats following the exercise training (effect size (95% confidence interval (CI)) = 1.8 (0.5–3.0)). Plasma low-density lipoprotein–cholesterol and fasting glucose were lower in the exercise compared to the sedentary groups (d = 2.0 (0.7–3.2) and 1.8 (0.5–3.0), respectively). Plasma insulin was reduced in exercise compared to sedentary groups (d = 2.1 (0.8–3.4)). Some exercise × phenotype interactions showed that the highest decreases in insulin, homeostatic model assessment-insulin resistance, fasting and postprandial glucose were observed in the obese + exercise group (all, P < 0.01). The findings of this study suggest that interval aerobic training combined with strength exercise would improve body composition, and lipid and glycaemic profiles, especially in obese rats.  相似文献   

Dribbling determinants in sub-elite youth soccer players     

Matteo Zago  Andrea Gianluca Piovan  Isabella Annoni  Daniela Ciprandi  F. Marcello Iaia 《Journal of sports sciences》2016,34(5):411-419

Dribbling speed in soccer is considered critical to the outcome of the game and can assist in the talent identification process. However, little is known about the biomechanics of this skill. By means of a motion capture system, we aimed to quantitatively investigate the determinants of effective dribbling skill in a group of 10 Under-13 sub-elite players, divided by the median-split technique according to their dribbling test time (faster and slower groups). Foot-ball contacts cadence, centre of mass (CoM), ranges of motion (RoM), velocity and acceleration, as well as stride length, cadence and variability were computed. Hip and knee joint RoMs were also considered. Faster players, as compared to slower players, showed a 30% higher foot-ball cadence (3.0 ± 0.1 vs. 2.3 ± 0.2 contacts · s^?1, P < 0.01); reduced CoM mediolateral (0.91 ± 0.05 vs. 1.14 ± 0.16 m, P < 0.05) and vertical (0.19 ± 0.01 vs. 0.25 ± 0.03 m, P < 0.05) RoMs; higher right stride cadence (+20%, P < 0.05) with lower variability (P < 0.05); reduced hip and knee flexion RoMs (P < 0.05). In conclusion, faster players are able to run with the ball through a shorter path in a more economical way. To effectively develop dribbling skill, coaches are encouraged to design specific practices where high stride frequency and narrow run trajectories are required.  相似文献   

Effects of high-intensity interval training on cardiometabolic risk factors in overweight/obese women     

Abbie E. Smith-Ryan  Eric T. Trexler  Hailee L. Wingfield  Malia N.M. Blue 《Journal of sports sciences》2016,34(21):2038-2046

The purpose of this study was to evaluate two practical interval training protocols on cardiorespiratory fitness, lipids and body composition in overweight/obese women. Thirty women (mean ± SD; weight: 88.1 ± 15.9 kg; BMI: 32.0 ± 6.0 kg · m²) were randomly assigned to ten 1-min high-intensity intervals (90%VO₂ peak, 1 min recovery) or five 2-min high-intensity intervals (80–100% VO₂ peak, 1 min recovery) or control. Peak oxygen uptake (VO₂ peak), peak power output (PPO), body composition and fasting blood lipids were evaluated before and after 3 weeks of training, completed 3 days per week. Results from ANCOVA analyses demonstrated no significant training group differences for any primary variables (P > 0.05). When training groups were collapsed, 1MIN and 2MIN resulted in a significant increase in PPO (?18.9 ± 8.5 watts; P = 0.014) and time to exhaustion (?55.1 ± 16.4 s; P = 0.001); non-significant increase in VO₂ peak (?2.36 ± 1.34 ml · kg^?1 · min^?1; P = 0.185); and a significant decrease in fat mass (FM) (??1.96 ± 0.99 kg; P = 0.011). Short-term interval exercise training may be effective for decreasing FM and improving exercise tolerance in overweight and obese women.  相似文献
