The faster your feet leave the ground, the less impact your knees will have to absorb. Next time you run, go for 30 minutes and determine how far you went. Then, once a week for the next 4 weeks, try to go the same distance in less time. After those 4 weeks, pick a slightly longer distance, establish how long it takes you to run it, and then try to beat that time for the following 4 weeks. Eventually, you should be able to do all distances faster and with better form.
Basketball players sprain their ankles more often than they nail groupies.
We've all seen the slow-motion replays and watched the players mouth obscenities at the camera. When this happens, the natural inclination of your ankle is to roll outward. The ligaments in your ankle are quickly stretched beyond their natural length, and inflammation ensues. Stretch your calves. Tight calves increase the chance of a sprain, Dr. DiNubile says.
