After Martin van Kesteren:
I finally got to read the blog in the original thread. I was shaking my head as I read some things. The author (Martin) didn’t mention if he had any previous history. He mentioned dancing on stone surface and a few other things.
My take has always been that you adjust your dancing, how you step, and how you turn to two things. First is the footwear you are wearing. Second is the surface that you are dancing on. The same turn or pivot on a sprung wood studio floor is very different on marble, concrete, asphalt, stone, uneven surface. In salsa I have know leaders who danced in sports sneakers. Is it doable? Yes. Is it advisable? No. For some of the feet movement, the sports sneakers and dress shoes are enemy of your knees. It is not worth destroying your knees for sake of vanity or athleticism, if you are overcompensating.
Pay attention to your body and any signs of pain early. Start taking preventative measures when you dance. Don’t let dancing aggravate it. Rather eliminate anything in dancing that can make things worse.
I have seen dancers in 30s and 40s aggravate their injuries by ignoring to take care early. Often times putting them off dance floor for 6-7 months. Due to running downhill once, I ended up putting strain on my knees that took 2 months to heel. I was in mid thirties then. Once while doing enrosque drills everything went fine. Then suddenly after 2 weeks I had a strange strain in upper right leg. I could not figure out why it should happen. For two weeks I hadn’t done anything. Then I remember the drill. When I tried to mimick it, I knew that was the culprit. It would only shoot up in a certain position and angle my feet hit something no matter how softly. Otherwise in normal walking or dancing I didn’t feel anything. I had almost full range of motion. The best way to describe it is imagine trying to kick a soccer ball with side of your foot like when you are making a pass, the pain would suddenly shoot up. For a few seconds it was excruciating. If a follower banged her feet slightly against my inside foot, exactly the same. It took almost a year to fully recover. During that time I had half a dozen occasions when a follower in salsa or tango hit my foot at wrong spot. Best way to describe it is brushed hard. Not kick me or bang my foot.
Athleticism has come easy to me and I have naturally high endurance. Luckily I have been injury free through the sports and dancing. Have seen a lot of people develop injuries in both activities. People try to power through their pain and instead of letting the body heal, end up making it permanent or more serious.
Then there are age related ailments that start to creep in. One more reason to listen to your body and adjust your dancing style without giving up enjoyment you get.
