Can toned muscles help protect the joints from trauma? How?

Similar questions: toned muscles help protect joints trauma.

Trained muscles can protect against some types of joint damage caused by minor repeated trauma This example is from a knee joint:PREVENTION Protection against meniscal injury and from the arthritic changes after loss or injury to the meniscus can be best achieved by decreasing the impact loading the knee joint is exposed to. Joint forces are decreased by increasing the muscular conditioning of the leg; the more force that the muscles absorb, and the more they are able to protect the joint from abnormal rotations, the less damage the internal surfaces of the joint are exposed to. Specifically, for the skier, the muscular conditioning must be directed toward increasing the lower leg's ability to accept an eccentric load.

Eccentric contractions are defined as force produced by the muscle as it elongates, as the quadriceps (thighs) muscle does with knee flexion (as opposed to shortens, as the quadriceps does with knee extension). The ability to accept an eccentric load is the first skill lost after a knee injury or after a period of immobilization or deconditioning, and is the-last to be regained in a general conditioning program. This combination of the most difficult muscle system to condition, and the most easily de-conditioned, explains, in part, why so many knee injuries persist, despite tremendous advances in boot and binding technology.

Adaptation of the human body to the advancing technology still requires intelligent sport specific conditioning and plain old sweat. Specific eccentric exercises and side-to-side positioning exercises are extremely effective at preparing the knee for the loading conditions seen while skiing. A preseason program should include flexibility, agility and strength workouts.

Specifically for the knee a combination of core strengthening and concentric and eccentric exercises to include a daily five minute single stand one-third knee bend, a linebacker double stance five minute one-third knee bend, and a five minute side-to-side hop, with emphasis on slowly absorbing the force of the body weight as the knee bends. These simple focused exercises can be increased in intensity by adding an elastic resistance cord and can dramatically strengthen the lower limb musculature. Protection from impact loading is also gained by using Sorbothane type inserts in running shoes and ski boots, by training on soft surfaces, and by biasing the conditioning program toward non-impact regimens, of which bicycling is by far the kindest to the knee.

The conditioning program must be continued throughout the season, as there is overwhelming evidence that athletes who perform but do not train are quite susceptible to career ending injuries. ------Basically, the more impact a muscle will take, the less impact the joint will take, so minor trauma, particularly to joints like ankles and knees, can be mitigated by well-developed leg muscles.

Large display TOUCHSCREEN computers, SEEMS like a lot of wear and tear on the shoulder joints and muscles.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
