Bobby McGee Study Update 7/24

The moment of truth arrived this week when we measured results of study participants as they ran their second 200-meter and 2k halfway through the study. This was a test performed at the midpoint of their training, during the week requiring athletes to run their highest mileage. Therefore, many of the partipants were fatigued, a consideration which amplifies their improvements!

Results of All 14 Involved Athletes:
 
1. The group was on average six seconds faster in the second test than the first. Almost 60% of participants improved their times on the 2k test, and the average improvement was by 23.1 seconds.
