Here we have an athlete preparing for a game.
They’ve put on their gear and done their warmup,
and now it’s time for one more routine— stretching.
Typically, athletes stretch before physical activity to avoid injuries
like muscle strains and tears.
But does stretching actually prevent these issues?
And if so, how long do the benefits of stretching last?
To answer these questions,
we need to know what's actually happening in the body when we stretch.
There are two kinds of stretching our athlete might be doing.
Dynamic stretches, which are controlled movements
that engage a range of muscles throughout the motion.
And static stretches, where the stretcher holds a position
to keep specific muscles at a fixed length and tension.
Our athlete is currently doing a static hamstring stretch—
a 30 second interval where he pulls his hamstring
beyond its usual range of motion.
