贫困山区的中学由于普遍缺乏体育锻炼的场地,是导致中学生身体素质低下的主要原因。体育教师若善于因地制宜地引导学生进行体育锻炼,即使条件简陋,依然能够达到增强学生体质的教学目的。 Due to the general lack of physical exercise in secondary schools in poor mountain areas is the main reason leading to lower physical fitness of secondary school students. Physical education teachers who are good at guiding students to carry out physical exercises according to the local conditions can still achieve the teaching purpose of enhancing the students’ physical constitution even if the conditions are poor.
