This all feels so fuzzy wuzzy to me. I would love to see some data which support this. And not sugar pills to world class athletes, but to recreational athletes… not marathoners, but 5k plodders and ordinary gym rats.
It is so easy to blame less than spectacular results on ‘lack of faith’ yet the prescription for having faith has no rigor… there is no recipe that works for everyone. …Or can even be duplicate by teammates.
Faith is no substitute for good training. Training has a mental aspect, as well as a physical one. Mental reviews of form, and process… even visualization (although I bet silver and bronze medalists also visualized winning), should probably be a part of the training program.
You need to show more to convince me that Faith is the distinguishing difference that supports a winning performance.
