About running and skipping rope in junior high school physical education entrance examination.

Technically speaking ~ ~ feet alternate faster ~ Don't jump too high, the rope should not be too long, mainly depends on your hands, and you should throw it with the strength of your wrist ~ (because you can't get up quickly if you throw your arm). Then you can throw it quickly, alternating as quickly as you do leg lifts. You can try it. It's the fastest way to jump with your feet. If you alternate, you can have an acceleration like lifting your legs. At that time, you will find that there is only one problem, that is, your arms can't keep up. My sister ~ senior one, jumps alternately like that, 1 minute more than 200 jumps. . . I even asked her for advice. . But because I'm not a very fast pitcher, I jump with my feet ~ ~ because I find my feet jump fast and my hands can't jump ... In short ~ ~ It depends on my personal situation ~ ~ It's still my habit.
