abstract="8th degree students were asked by questionnaire on their leisure-time activities. Home work was shown to interfere with time spent in front of the television screen, whereas sports did not. Girls spent more time at homework than boys, and less time at television. Also they were less active in sports, especially in the lower grade schools.<p /><p>Language: de</p>",
