- ANKLE SPRAIN
Twisting an ankle doesn’t just happen running outdoors. Jogging on a treadmill can also result in an ankle sprain, says Cindy Trowbridge, Ph.D., associate professor of kinesiology at the University of Texas at Arlington. “The biggest problem running indoors on a treadmill is losing your focus and accidentally stepping half on and half off the treadmill while the belt’s still moving.” If you jump off the treadmill quickly, your ankle may roll in an unnatural direction.
Running outside on uneven terrain or up and off curbs also increases the risk of an ankle sprain. HOW TO STAY SAFE: Most treadmills have a clip you attach to your clothes that stops the machine if you fall. Says Trowbridge, “If you run outdoors, stay on level sidewalks or at a park, versus running where you have to go up and down off a curb.” Look for paved, even walkways because uneven terrain and potholes can be problems.
