I'm Clover Zatzman, here at the Ice House, and this is what is harder on the joints ice skating or modern dance. Do to the increase level of difficulty that has become required over recent years for Olympic competition, figure skating has now become much harder on the joints than modern dance. Constant landing of jumps puts a strain on the landing knee over time. Difficult positions in spin such as a donut or Biellmann's spin can also put a strain on the skaters back over time if they don't warm up properly before practicing these elements. Repeated falls during practice sessions can put a strain on the skaters spine and backbone. Many skaters can end up with hip and knee problems as well as stress fractures. Many skaters I know have had to have surgery for meniscus tears either from landing of jumps or from ice dancing from deep knee bends. I myself had to have surgery last year for a stress fracture in my right foot due to many years of ice skating. Having proper technique on jumps, not being overtired on practices and warming up properly before coming to the ice can help prevent injuries. Studies show that when a skater comes down on their landing knee the knee is absorbing up to 3 to 4 times the skater's actual body weight. A skater can take steps to prevent injury. Skaters should always make sure to warm up properly before getting onto the ice especially advanced skaters. Stretching is very important as well before getting onto the ice. Using proper technique when jumping, spinning, and doing ice dance things such as twizzles are very excellent ways to prevent injury. Although skating can be difficult on the joints it's still a beautiful and amazing sport to watch and it's enjoyable to do. Making sure to take steps to prevent injury can help make your joints happier after skating.
