热身的真收益是急性表现 + 针对性防伤 (如 Nordic 防腘绳肌伤), 不是泛泛拉一拉 · 长静态拉伸赛前反而削力 · cool-down 多半是仪式

Does stretching prevent injury
Holding a stretch for tens of seconds before performing briefly lowers subsequent strength and power. For anything explosive, the pre-game static routine buys little injury protection and costs output up front — warm up with dynamic movement.

DOMS soreness
A cool-down cannot clear DOMS because soreness was never lactate: lactate returns to baseline within an hour of stopping, while soreness peaks the next day. It comes from eccentric micro-damage.
Training injuries
The part of a warm-up worth doing is raising temperature and rehearsing the movement, which makes the session better. It does not offset the first factor in training injury — a jump in load — which only pacing can manage.

What a warm-up actually raises

Stop 1/5

热身到底在升什么

A warm-up is worth doing, but first understand what it actually does — that's how you know how to warm up, and what not to expect from it.

A good warm-up raises: muscle temperature (lowering viscosity, smoothing contraction), neural recruitment (the brain 'wakes' more motor units), metabolic and cardiorespiratory readiness, and the joints' entry into the range you'll use today. A common framework is RAMP (Raise / Activate / Mobilise / Potentiate): a gradual ramp from easy to near-target intensity, plus a few light-load rehearsals of the target movements.

Note the logic: a warm-up is about 'gradually bringing the system up to temperature and preparing for what you're about to do', not a ritual of 'jogging a lap and stretching at random' unrelated to the coming movement. The next scene looks at its real record on 'performance' and 'injury prevention' separately.
