3. A treadmill with shock absorbing function as recited in claim 1, wherein: the second target value is the user's weight G.
4. A treadmill with shock absorbing function as recited in claim 1, wherein: the third target value is the buffer pressure value P1.
5. A treadmill with shock absorbing function as claimed in claim 1, wherein: the outside of the air bag (4) is provided with a protective shock absorption structure for reducing the abrasion of the air bag (4).
6. A treadmill with shock absorbing function as recited in claim 5, wherein: the protective shock absorption structure comprises a wear-resistant body (5) wrapped outside the air bag (4).
7. A treadmill with shock absorbing function as recited in claim 6, wherein: at least one shock absorption body (6) with the height lower than that of the wear-resistant body (5) is uniformly arranged on the mounting seat (3) at intervals in the circumferential direction around the wear-resistant body (5).
8. A treadmill with shock absorbing function as recited in claim 7, wherein: the thickness of the outer wall of the wear-resistant body (5) and/or the shock absorption body (6) is gradually increased from the top to the bottom.
