The learning panel's requirements for learning always involve the combination of theory and practice; to know how to do it, to be able to do it, and to understand why.
Knowledge and action, coexist.
Li Shi first organized some theoretical materials on middle and long-distance running, focusing on the difference in body characteristics between middle and long-distance running and sprinting.
"If you carefully study the differences in physical characteristics between sprinters and distance runners, you'll find that sprinters tend to have thicker legs, while distance runners have slimmer legs."
"Long-distance running is an aerobic exercise that mainly relies on the oxidation energy supply system, consuming more fat for energy; while sprinting is mainly an anaerobic exercise, relying on the ATP-CP and glycolysis energy supply systems."

Li Shi did not just skim through the material.
