Besides shin splints, are there any body parts that people have noticed are prone to injury or pain at OCS? Anything that would make you say, "Damn, I wish I had worked harder on training my _______ before OCS" I am at the end of sophomore year (of college) right now, so I have until the end of senior year to make any significant improvements. And yes, I did use the search function before posting. *Well I forgot to read the thread "Knees!"....... so anything besides knees too?
A majority of injuries occur during the first few weeks of a training program because the musculature is not used to the forces put on them. That being said, you need to do a good, all around, strengthening and stretching program prior to starting. This will help to keep from getting these injuries. Shin splints are normally caused by weak lower leg musculature, so giving them time to get strong is essential.
Also, make sure your shoes are proper for your feet. Go to a good running shoe store that can evaluate you and put you in a good set of shoes. You may need to get some orthotic inserts if there are more than minor problems. Proper biomechanics start at the feet and work their way up, so if your shoes are not proper, then you can have problems in the ankles, knees, hips, etc.
Last I knew, the medics at OCS have received training in Athletic Training (sports medicine), so you should have someone there who can do an evaluation on injuries, treat them properly, and make suggestions on taping, bracing, and rehab.
