男子赛艇运动员与训练有关的有氧无氧能力和激素变化

观察了１５名男子赛艇运动员为期３０周训练中最大做功能力、最大乳酸值、最大摄氧量及心脏形态和功能的变化及相应时期的血清睾酮、游离睾酮、皮质醇的急慢性效应。在以力量训练为主的准备期，变化较小，以专项训练为主的准备期，心功能和有氧能力明显改善。最大负荷后及高强度训练１２周后，血清睾酮降低。提示在不同训练周期中力量—耐力训练应合理安排，有利于发挥机体适应能力。

Can ubuntu provide a model for citizenship education in African democracies?

Some proponents of Africanism argue that African traditional education and the principles of ubuntu should provide the framework for citizenship education. While conceding that understandable concerns lie behind defences of ubuntu as underpinning African democracy, we argue that the Africanist perspective faces various problems and makes substantial errors: political, moral, epistemic and educational. While democracy and democratic citizenship necessarily involve sensitivity to local context, their fundamental principles and tenets are universal. Failure to acknowledge this comes at a substantial price. Taking as its initial focus an analysis and critical evaluation of Malegapuru William Makgoba's critique of liberal democracy, the paper questions the purported uniqueness of ubuntu and its value and efficiency as a practical guide to action and policy, as well as its capacity to indicate how conflict between its associate principles and values might be resolved, insofar as these principles and values are indeed morally worthy.
