I am fascinated by listening to some book-reading youtube channels recently. Today I listened to a speech by FanDeng years ago. He mentioned a few skills about jogging he learnt after reading a book authored by a trainer.
He confessed in the speech that he hated jogging. Jogging will give him low glucose sensation, dizziness or feeling threw up. One day the trainer approached him, offered to teach him how to properly run to lose weight.
He said with 5 months of training by the guy, he just completed a half marathon successfully. He was still a chubby person standing on the stage, to accomplish a half marathon by a figure like him really struck me.
I have some friends who have finished a half marathon recently, with a lot of training. She herself is a very thin person that fits the image of a marathon runner. For a still overweighted person like the speaker on the stage, how could he achieve that?
He pointed out two important scientific facts about jogging stated in the book, which may provide the answer
If a person can run 6km with the heart rate maintained below 160, this same person can safely finish a half marathon of 21km.
If a person wants to lose weight, he should set a pace with a lower heart rate. A moderate heart rate will burn body fat first. In comparison, a fast heart rate will burn sugar in the body first, that way, the runner may easily run into a low glucose situation. When you have low sugar inside your body, you may experience some sensations such as fainting, dizziness, or cold sweating.
Cool!
These both pieces of information are very useful for me. I am pre-diabetic, so low glucose is a constant worry when jogging if I don't eat enough beforehand. So wisely to choose the correct pace to run is beneficial. Also, I don't feel so hard to run a longer distance anymore, to give a few months of training, I may be able to do that.
