Although tennis is a good workout for the legs it also can be abusive. So that could be the reason that some have injury problems at the end of summer. I had leg problems in the past but once I started exercising my legs I've had no problems.That is when you fear a big tear. I find it ironic there are so many of us having this at the end of summer. You would think we would be at our "most prepared" after regular summer play. I sure would like to know the best way to prevent it. If it's squats and lunges ... I will do them. If it's roller ball massage... I'm in. Same with stretching. The ironic thing with my hamstring injury was it followed the most consistent month of leg stretching ever for me. The calf tear scared me (and p!ssed me off) ... so I was stretching every day. I got lucky on both calf and hamstring because they felt more like a major "grab" than a tear. I only wore the calf sleeves for a couple of weeks. Been off for 2 weeks with hamstring. I think I can hit ... but not much chance to play points because I still feel it.
I thought I didn't need to work my legs because I played so much tennis so I only worked upper body but this was a mistake. Many injuries are caused by muscle imbalance and tennis over works the lower leg and hamstring muscles. So over time the imbalance on the legs causes problems.
I do squats or lunges combined with calf raises 2-3 times a week combined with some stretching and so far no problems. I don't have an off season so I play on average 5 days a week and other than soreness from a tough 3 setter I have no problems.
I will say it again for you guys that want to play competitive tennis into old age you really need to do an all around strength training program. It makes a huge difference, but if not you can keep posting about all your aches and pains.
