智龙迷城 光克:这两句话超难翻译，请高手帮翻译一下

结合上文看这句话里的Speak of 好像还不是仅仅指“说”，好像有点“如果只是说说”的意思。让我不解的是这句话从developmental physical activity 之后的部分和前面部分是什么关系。第二句话也很复杂，尤其是最后的at that搞不明白指的是什么。sociology of sport：体育社会学physiology of exercise运动生理学 physical activity 身体活动 physical recreation 体育休闲 expressive movement表现性运动

If we continue to speak of sociology of sport, physiology of exercise, etc., it will just be a matter of time before these other disciplines and professions
awake to the importance of what we believe to be our professional task--the discovery, gathering, and dissemination of knowledge about, and the promotion of it to the extent that such promulgation is socially desirable, developmental physical activity through the media of exercise, sport, physical recreation, and expressive movement. It is our contention that the present trend, truly a debilitating fractionization, will in time if unchecked result in our developing profession being regarded as simply one more trade, and not a very important one at that.
底下的两位朋友的答案不对，是用翻译软件翻译的吧呵呵。最起码要读起来意思要通顺才行。
