A muscle biopsy is a procedure used to remove and examine a piece of tissue microscopically.
Athletes all over the nation that play fall sports in high schools and colleges are involved in winter strength and conditioning programs.
If you were to do a muscle biopsy on a single fiber of these athletes prior to training and then did the same biopsy post training you will find something very interesting.
The athletes may be faster when you time them. They may be quicker on agility tests. They may be significantly stronger on strength tests. They may demonstrate greater muscular endurance. They may be leaner.

You would also find this as you examined the newly developed fiber.....the shortening speed of the single muscle fiber that was biopsied did not change.
Something to think about as you design their programs to Get them Strong
