HOW DO YOU STRAIN YOUR HAMSTRING?
So imagine you just played a pick-up game of soccer for an hour. You go for that final break-away and 
BAM it feels like you’ve been hit in the leg with a hammer.
.
This has happened to a lot of us, likely you’ve experienced a hamstring strain. An injury to one of the 
thigh muscles, and one of the most common strains in the body.
.
How does this happen? When you’re running 
at high speeds there’s a lot more demand to the muscles of the hip (compared to jogging it’s more the knees).
.
The hamstrings run from the back of your pelvis to below your knees. So when your hip is driving your leg forward 
, the hamstrings act as the breaks 
to slow down the leg in the last part of ‘swing phase’. This breaking action is called ‘eccentric contraction’ of the muscle.
.
The most force goes through a muscle with this eccentric load. It’s why you see these injuries happen on TV 
with no contact to an athlete. Examples:Sprinters at the end of a race
Baseball players reaching for 1st base
️Soccer players following through on kicks
.
These injuries are commonly mismanaged 
and a lot of times rest doesn’t help the muscle. In fact 1/3 of these injuries reoccur 
within 
weeks of return to sport (Heider 2010)
