Nine male student games players consumed either flavoured water (0.1 g carbohydrate, Na+ 6 mmol · l?1), a solution containing 6.5% carbohydrate-electrolytes (6.5 g carbohydrate, Na+ 21 mmol · l?1) or a taste placebo (Na+ 2 mmol · l?1) during an intermittent shuttle test performed on three separate occasions at an ambient temperature of 30°C (dry bulb). The test involved five 15-min sets of repeated cycles of walking and variable speed running, each separated by a 4-min rest (part A of the test), followed by 60 s run/60 s rest until exhaustion (part B of the test). The participants drank 6.5 ml · kg?1 of fluid as a bolus just before exercise and thereafter 4.5 ml · kg?1 during every exercise set and rest period (19 min). There was a trial order effect. The total distance completed by the participants was greater in trial 3 (8441 ± 873 m) than in trial 1 (6839 ± 512, P < 0.05). This represented a 19% improvement in exercise capacity. However, the trials were performed in a random counterbalanced order and the participants completed 8634 ± 653 m, 7786 ± 741 m and 7099 ± 647 m in the flavoured water (FW), placebo (P) and carbohydrate-electrolyte (CE) trials, respectively (P = 0.08). Sprint performance was not different between the trials but was impaired over time (FW vs P vs CE: set 1, 2.41 ± 0.02 vs 2.39 ± 0.03 vs 2.39 ± 0.03 s; end set, 2.46 ± 0.03 vs 2.47 ± 0.03 vs 2.47 ± 0.02 s; main effect time, P < 0.01). The rate of rise in rectal temperature was greater in the carbohydrate-electrolyte trial (rise in rectal temperature/duration of trial, °C · h?1; FW vs CE, P < 0.05; P vs CE, N.S.). Blood glucose concentrations were higher in the carbohydrate-electrolyte than in the other two trials (FW vs P vs CE: rest, 4.4 ± 0.1 vs 4.3 ± 0.1 vs 4.2 ± 0.1 mmol · l?1; end of exercise, 5.4 ± 0.3 vs 6.4 ± 0.6 vs 7.2 ± 0.5 mmol · l?1; main effect trial, P < 0.05; main effect time, P < 0.01). Plasma free fatty acid concentrations at the end of exercise were lower in the carbohydrate-electrolyte trial than in the other two trials (FW vs P vs CE: 0.57 ± 0.08 vs 0.53 ± 0.11 vs 0.29 ± 0.04 mmol · l?1; interaction, P < 0.01). The correlation between the rate of rise in rectal temperature (°C · h?1) and the distance completed was ?0.91, ?0.92 and ?0.96 in the flavoured water, placebo and carbohydrate-electrolyte conditions, respectively (P < 0.01). Heart rate, blood pressure, plasma ammonia, blood lactate, plasma volume and rate of perceived exertion were not different between the three fluid trials. Although drinking the carbohydrate-electrolyte solution induced greater metabolic changes than the flavoured water and placebo solutions, it is unlikely that in these unacclimated males carbohydrate availability was a limiting factor in the performance of intermittent running in hot environmental conditions. 相似文献

As Hong Kong approached its hand-over to Chinese sovereignty, it has been instructive to compare its experience with that in other former British colonies. This article focuses on how education policies in areas such as the medium of instruction and curriculum changed as Singapore moved towards self-government and independence in the 1950s and 1960s. It also compares the changes that took place in Singapore with those currently occurring in Hong Kong. Observations will be made about the likelihood of the 'one country, two systems' concept working in Hong Kong after 1997. 相似文献

采用开放式访谈法对损伤运动员康复过程中的三个阶段进行了访谈研究.运动员将在损伤后的第一周,损伤后的15～20天及损伤后的30天接受访谈.这三次开放性的访谈是让运动员在没有任何前提约束的情况下自由地谈论他们的经历.被试是美国东南部大学的NCAA一级运动员（5名）.对访谈结果的分析揭示了四个主题：视点情绪反应,损伤应对及人际关系和几个次级主题.结论：第一,运动损伤在很大程度上影响了运动员的生活;第二,运动损伤对于本研究中的每名运动员都是一次独特的经历;最后,通过多重现象访谈法给运动员提供了公开谈论他们损伤康复经验的机会. 相似文献

This article focuses on the joint attempt by the Singapore Government and the minority Malay Community during the decade from 1982 to 1992, primarily through the formation of Mendaki (the Council on Education for Muslim Children), to tackle the problem of Malay educational underachievement. It analyzes the complex interplay of social, economic and political factors that led to the formation of Mendaki. The strategies adopted by Mendaki to improve Malay educational achievement will also be examined, along with the problems it encountered, in particular with regard to its legitimacy among the Malay community. A major theme running through the article is that the issue of Malay educational underachievement is closely related to, and cannot be considered in isolation from, wider political, social and economic trends pertaining to the problems of interethnic harmony in a multiethnic society . 相似文献
