The low back is the one to watch
Low back accounted for 16.7% of injuries in the collegiate study, the largest single site. A third of the lumbar injuries were spondylolysis, a stress injury to the bony arch of a vertebra, and three quarters of those ended the athlete's season. Adolescent back pain that keeps coming back after extension work is worth having imaged rather than trained through. That is a physician's call, not a coach's.
