"In particular, cardiopulmonary endurance showed the most obvious gains." Taking fourth graders as an example, he notes that on the first exam, their average for the 800 meters was over five minutes. By the end of the term, the kids were running nearly a minute faster.
「尤其是心肺耐力進步最明顯」，他以四年級的學生為例，八百公尺跑走第一次測試平均跑五分多鐘，三個月後再測，平均是四分多鐘，足足快了將近一分鐘。
