Football metabolomics

Following on the recent announcement of the Atlanta Hawks training center, here’s a Nov. 2015 research paper from Emory’s sports cardiologist Jonathan Kim, published in Annals of Sports Medicine and Research.

Kim and colleagues from Emory Clinical Cardiovascular Research Institute studied blood samples from 15 freshman football players at Georgia Tech before and after their first competitive season. The researchers had the help of metabolomics expert Dean Jones. Kim has also previously studied blood pressure risk factors in college football players.

On average, football players’ resting heart rate went down significantly (72 to 61 beats per minute), but there were no significant changes in body mass index or blood pressure. The research team observed changes in players’ amino acid metabolism, which they attribute to muscle buildup.

This finding may seem obvious, but imagine what a larger, more detailed analysis could do: start to replace locker room myths and marketing aimed at bodybuilders with science. This was a small, preliminary study, and the authors note they were not able to assess diet or nutritional supplementation. Read more
