The elbow should be a mobile joint according to the joint-by-joint theory. A. true B. false
Weegy: A. [ true Ankle ? Mobility (sagittal) Knee ? Stability Hip ? Mobility (multi-planar) Lumbar Spine ? Stability Thoracic Spine ? Mobility Scapula ? Stability Gleno-humeral ? Mobility Over the past 20 years, we have progressed from the approach of training by body part to a more intelligent approach of training by movement pattern. In fact, the phrase movements, not muscles has almost become an overused one, and frankly, that?s progress. Most good coaches and trainers have given up on the old chest-shoulder-triceps method and moved to push-pull, hip-extend, knee-extend programs. Still, the movement-not-muscles philosophy probably should have gone a step further. Injuries relate closely to proper joint function, or more appropriately, to joint dysfunction. Problems at one joint usually show up as pain in the joint above or below. The primary illustration is in the lower back. It?s clear we need core stability, and it?s also obvious many people suffer from back pain. The intriguing part lies in the theory behind low back pain?the new theory of the cause: loss of hip mobility. Loss of function in the joint below?in the case of the lumbar spine, it?s the hips?seems to affect the joint or joints above. In other words, if the hips can?t move, the lumbar spine will. The problem is the hips are designed for mobility, and the lumbar spine for stability. ] ] (More)
