Repetitive use injuries

Now that I'm 42. I have to believe my body is getting old. I've fought this notion for years even though I feel it emotionally and not physically. All these years I got used to the aches and pains. I accepted them as part of the old knee and back injuries. When my strong knee started to bother me, I simply felt it was because I had been sedentary. That might be true, but the tendonitis in the elbow is another sign that I can't push my body to new limits like I used to. This week I played three matches in as many days. Coming off the court I knew I needed to turn my attention on rehabilitation. To me that means being diligent about icing at night, massaging the sore spot throughout the day, stretching before and after any drills and training. Finally, get back into weights training twice a week to start. The elbow has improved and so has the knee. I can tell that total rest is not the answer, but light workout that's controlled seems to be the best. On court footwork and drills are the best. Followed by light weights and stretching. I can already feel better walking down stairs. Calf stretches and weight lifts have also helped the patella tendonitis improve. I might also look for the athletic tapes to use on my shine that I see on the tennis pros. So far so good. I just have to keep it up.
