Running is something that when we are young we do very naturally. If you take the time to look at young children playing ath the park you can see what efficient running looks like. What happens between then and when a youth starts to become serious in his or her sport. Overtraining is a big culprit in the changing of a persons biomechanics as they get older. I have been reading a great book call Chi running that sheds some light on the physical, mental,and spirtual characteristics that can help in creating effortless running. I will take this information and use it to make some comments about how it can benefit a young athlete in learning proper sprinting technique in my message board this coming week. Strengthcoach.
