Maybe there ought to be an HR division.
Arrojo - good news on your running, that's awesome. Like David said, I'd take it easy on the true sprints. I think it's easy to extend the ROM beyond what your body is ready for. When I got the clearance to begin running, I wanted to gear up for soccer season, so I did a lunch time loop up the hill behind my office. Basically ran a total of about 3 miles, but in the middle of it, I did 5 or so 150m sprints up a fairly steep hill, thinking that it would be good for hips and muscles around the hip and also for the lungs. I would often get a torn-flexor type of pain a little later in the run, so I essentially stopped doing that. I then started soccer and I have a hard time slowing down, like a dog after a ball. I played sweeper and we always held a tight offside line close to the middle of the field. When a young buck would bust through the offside line and the ref wasn't paying attention (like always
), it was my job to sprint after them and I would usually have 30 yards or more of a straight sprint. Halfway through the season the flexor muscles got more and more tendor. The pain would go way with icing and a night's rest, but it would always come back at each game, sooner in the game each time, eventually I just stopped playing.
I've been playing indoor soccer, lately, which has much shorter distances and much less time, but still a lot of sprinting, but usually more side to side cutting and there's been no pain. The cool thing about indoor, is that I don't feel like I'm any different than I used to be before OA, other than my cardio isn't as good.
Also, there are probabaly some really good exercise and stretches to help extend the ROM so that your hips are ready for the sprinting.
