I discussed shin splint causes, treatments, and prevention in response to another recent Ask an ACE Expert question. It could be that whenever your friend runs on a treadmill, she goes too fast or too far for her training level, doesn’t warm up adequately, or isn’t wearing appropriate footwear for this activity, all of which increase her risk for shin splints.
Jumping, running, and other high-impact activities are usually the culprits with shin splints. Low- and no-impact activities place less stress on the lower body, reducing the likelihood of developing this painful condition, but still offer a way to work out at a moderate-to-vigorous level. Assuming your friend is currently symptom-free, she could include the following in her exercise plan — outdoor or stationary bicycling, swimming, and low-impact group fitness classes; using stair climbers, ellipticals, and rowing machines. Brisk walking is another great cardio exercise that helps strengthen the anterior and posterior tibialis muscles located in the lower leg — the muscles that typically hurt when you have shin splints.
Anyone experiencing recurring or persistent shin splints should be seen by a health care provider for a complete evaluation of the problem
