Again, i take it quite carefully as its not serious. I've played for 7 or 8 years and only ever been injured, seriously, once. Its a risk I will take for now. Maybe not so much if I have the opportunity to go any further but for the time being I'll continue in a similar fashion as to how I have done. I see it as good sprint training. If I wasnt playing I'd be doing some other high intensity activity which carries similar risk.
