Strength coaches are often the ones tasked with managing hamstring strain. Not just to minimize the chances of an injury in the first place but also to reduce future strains. Because having suffered one strain an athlete is much more likely to be injured again.
One technique that is often used is the Nordic curl and recent analysis suggests that it is very effective.

Even so, is not quite clear how the Nordic curl produces its benefits.
It is an eccentric exercise so it increases fascicle lengths and short biceps femoris fascicles that are a risk factor. However, some conventional (eccentric-concentric) exercises can cause similar increases that have to date not been identified as having injury-prevention potential.

Whatever the reason, if you are a Judo or any other sort of competitor and you are prone to hamstring strains and you aren't already using Nordic Curl exercise, it is worthwhile talking to your strength coach and introducing them as we know that they can help.
If you are not familiar with the nordic curl exercise The video below should help.
