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

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.

Canada and the Pan-American Games

Abstract

Canadians have been involved in every edition of the Pan-American Games since they were inaugurated in Buenos Aires in 1951. That participation has provided thousands of Canadian athletes, coaches, and officials memorable international experiences. But the focus of Canadian involvement with the Pan-Ams has been the staging of games as a strategy for city building, city branding, and infrastructural investment. This paper examines the Pan-American Games of Winnipeg in 1967 and 1999 and Toronto 2015 as exemplars of that strategy. It argues that with the successes of those games, major games hosting has become virtually an article of faith of Canadian sport policy.

增加值出口竞争力研究——基于新兴经济体样本

文章使用全球投入产出数据库(WIOD),对新兴经济体样本的增加值出口和新显示性比较优势指数进行测算和分析。研究发现,近年来新兴经济体相对于发达国家出口竞争力强劲,贸易实力提升显著。细分至行业,新兴经济体在第一产业中具有绝对优势,在第二产业的低端和中低端中具备竞争力,在第三产业方面,新兴经济体在传统服务业中具备一定的优势,但在高新技术服务业不具备竞争力。因此,在保留、强化和创新现有竞争优势的同时,新兴经济体仍需要大力发展高端制造业和新型服务业,增加产品科技含量。     

"SA8000"的道德正当性及其效应探析 --兼论经济全球化条件下我国企业的伦理建设

如何应对经济全球化条件下的“SA8000”运动,搞好企业伦理建设,是我国企业必须面对的重大问题。“SA8000”无论就其所包含的伦理内涵还是作为伦理建设的手段,已深深地植根于经济活动,是源自经济活动本身和经济社会发展的伦理要求,体现了经济全球化条件下伦理建设全球化的合理正当要求。依据“SA8000”进行伦理建设,对我国企业在全球化过程中竞争力的提升和内部关系的协调都至关重要。
