With regard to the hamstring, perhaps massaging with deep Heat or similar before stretching might help.
With regard to injuries, I had no problems with contact games like football or rugby, but squash was a bugger. The most painful injury occurring whan I was introducing a not quick but powerful frien to the game. I played a ball to the back of the court and moved to the T. It seemed ages had passed so I turned round to see if he had got to the ball, only to have the ball , which had been hit with great force smack me straight in the eye. It was this that made me realise that boxers wearing sunglasses after a fight is not just bruise hiding vanity.
