血糖监测设备的问题在于存在15分钟的延迟。所以，我之前看了下应用，对自己说：“天哪，我感觉低血糖了。”然后她低头一看，说：“它告诉我我没事。”15分钟后读数突然下降，你会说：发生了什么？
我从中得到了什么好处？因此，我对用于健身的连续血糖监测设备有点悲观，因为它们反应慢。
The problem with glucose monitoring devices is that there is a 15-minute delay. So, I looked at the app earlier and said to myself, "Man, I'm feeling low blood sugar." Then she looks down and says, "He's telling me I'm okay." After 15 minutes the reading suddenly drops, and you say: What happened? What benefit did I gain from that? Therefore, I am a little pessimistic about continuous glucose monitoring devices for fitness because they are slow.
它反应慢的原因在于它实际上不在你的血液中，而是在你的肌肉里。它是一根扎入肌肉的针，试图捕捉细胞间的游离葡萄糖。葡萄糖从血液进入细胞间隙需要更长的时间，所以大约有15分钟的延迟。
The reason it's slow is that it's not actually in your blood, but in your muscles. It is a needle that goes into your muscles and tries to capture the free glucose between your cells. Glucose takes much longer to move from your blood into the spaces between your cells, so there is a delay of about 15 minutes.
