Antidepressant effects associated with different exercise conditions in participants with depression: a pilot study

In this article, we examined the antidepressant influence of an 8-week-long aerobic exercise intervention in which two training parameters were manipulated: exercise frequency and group environment. Twenty-three individuals with elevated symptoms of depression were recruited in a sport and fitness facility and agreed to participate in this 8-week study. They were randomly assigned to three groups: (a) low-frequency exercise (control) (n = 7), (b) high-frequency exercise (n = 8), and (c) high-frequency exercise + group-based intervention (n = 8). Participants completed the Beck Depression Inventory (BDI-II) at study entry, and at 4 and 8 weeks subsequently. The results showed that those in the high-frequency aerobic exercise experimental groups reported lower depression scores than those in the low-frequency (control) group at 4 weeks (13.2 +/- 7.3 and 11.7 +/- 3.1 vs. 22.4 +/- 7.5) and 8 weeks (10.9 +/- 8.1 and 9.6 +/- 2.5 vs. 20.7 +/- 6.3). However, alleviation in depressive symptoms was not found to be greater in those participants who received a group-based intervention.     

中国竞技乒乓球后备人才多维度可持续发展培养模式的探索与研究

中国竞技乒乓球后备人才的可持续发展是中国竞技乒乓球运动保持长盛不衰的根本保证。建国以来“举国体制”的培养方式造就了大量的世界冠军,使中国的乒乓球事业蓬勃发展,但随着中国改革开放的深入和对人才需求的不断变化,原有的培养模式已不能满足竞技乒乓球运动可持续发展的需要。“发展、协调、持续”是和谐发展的三个维度,本文旨在分析多维度和谐发展对于乒乓球后备人才培养的重要性,探索和研究构建中国竞技乒乓球后备人才可持续发展培养模式的可行性及其重要意义。
