在这个全民健身的时代里,跑步因方便、经济、效果佳等优点,当仁不让成为了绝大多数人的健身首选。许多上班族们因晨起赶时间、白天工作繁忙,只能把健身放在了晚饭后。经过一天的植物光合作用后,夜晚空气中的氧气含量比白天更高,所以在夜晚跑步,锻炼的效果也的确不错。 In this era of national fitness, running because of convenience, economy, good effect and so on, doing my part to become the vast majority of fitness first choice. Many office workers rush into the rush hour in the morning, they are busy during the day and can only put their fitness after dinner. After a day of plant photosynthesis, the oxygen content of the air in the night is higher than in the daytime, so running at night, the effect of exercise is indeed good.
