Main results: 1) In the next period to come, the speed of deterioration of Chinese students’ strength capacity as well as physical stamina capacity closely related to it can be slowed down as expected; their stamina capacity will continue to dete-riorate and such deterioration tends to happen to younger students; 2) aiming at how to develop and enhance stu-dents’ physical stamina capacity, the author put forward the following intervention measures: on the one hand, the guiding function of physical education examinations should be further exerted; on the other hand, elementary school physical education teaching and sports safety education should be strengthened continuously. |
