In gymnastics, the wrists bear a tremendous amount of weight and are exposed to forces that well exceed normal daily activities. A gymnast's wrist is inclined to injuries because many routines place the body's weight on the wrist while bending it backwards, and often require fast, jolting movements to the wrists and hands. This results in injuries that are both acute, such as fractures, dislocations and sprains, and chronic (long-term). Most acute gymnastic injuries are treated like any other sport injuries, however, two chronic injuries, dorsal wrist impingement and distal radial stress fractures, require specific treatment.
Dorsal wrist impingement
Dorsal wrist impingement is the most common injury to a gymnast's wrist. The injury results from the repetitive combination of hyperextension (extending or straightening the joint beyond its normal range of motion) and axial loading, (placing force on the joint or bone) The injury occurs when the dorsal (back) edge of the radius impinges on (strikes) the wrist bones. This injury often occurs during routines that include walkovers and handsprings. On a vault or balance beam, the injury can intensify when the stance is held with the full weight of the body on the wrist, such as during a handstand. When injury occurs, the gymnast feels pain and tenderness on the backside of the wrist. The pain usually subsides after the routine has ended.
very interesting article...continue here
As this is a very common enjurie on gymnasts and acrobat in general...I GOT MYSELF ONE!!!
Growing up in a communist country, sometime you are force to be creative because the luck of everything.
but thanks to this i have manage to safe myself a lot of money on buying things that could easily been made at home jsu using a bit of imagination.
so here it goes!
the idea is to get something under the palm of your hand that give you a comfortable angle and take a lot of pressure from your wrists. I use a peace of rubber and strap around with and elastic band, to hold it on place. again, the pictures below will explain it better.
Wrist down...if i lean forward it cause a lot of discomfort because the luck of flexibility do to the injure.
Notice how just by placing something under the back of the palm of your hand, give you a nice angle, allowing you to lean a lot forward...exactly what you need when doing a planche.
Hope this help!
All the best.
