You have to vary your intensity level depending on where you and your opponent are in your training cycle. Sometimes you are being asked to help prep somebody for a fight and they or their trainer may outright ask you to "put it on them" to get them ready. Like above, this may be especially true if it's somebody bigger or better who can't find people to push him. If you're coming off an injury, haven't been training regularly or are nearing a fight and want to avoid getting cut or hurt then this trumps everything and you should not be sparring hard and I would stop any sparring where your opponent doesn't respect this.
That's a good point.
Also- one thing I'll add about my camp is that we have a lot of pro fighters and we share a pretty good success rate for no injuries before fights and good results come fight time. Usually a month until two weeks out we pour it on pretty hard and then in the last 2 weeks it's toned down to avoid injuries and focus on the gameplan/techniques.
I ALWAYS tell guys if I have any worries before we get into sparring. I'll tell them "Hey man, I got this cut last month so take it easy on my left eye" or "My right shoulder is a bit sore so if you get a kimura on me on that shoulder don't torque it too hard" or whatever the case may be. I just let the guys know where I stand, and then they let me know where they stand on injuries and whatnot. I find that most guys are very receptive to that kind of information and they'll follow through with taking it easy on certain areas of your body when you tell them that stuff. Just be certain you're not sandbagging it and that you're still getting in quality training.
Another thing- with any kind of leg lock I always suggest to people to grab a hold of the submission, twist it a teeny tiny bit, then let your partner know you have it on them and then let them go. I never suggest going above 50% on any kind of leg lock in the gym since the knees and ankles are incredibly susceptible to injury and in the case of the knee you may not feel the damage until it's already done.
