The intersection of exercise and peptide science is an interesting one. Perhaps, it is even more so for those who have a workout regimen in addition to their work in the field of peptide chemistry. It was gratifying to see a recent article in Runner’s World that referenced oxytocin, a nine-residue peptide hormone, that we featured in blog post last week.1 In various posts, we referred to oxytocin as a “multitasking” peptide, due to its range of applications. It is typically known for its roles in uterine contractions, in milk letdown during lactation, in social and sexual bonding, taste preference, glucose tolerance and support bone remodeling.2

 The article in Runner’s World written by Peter Sagal, entitled, “Do You Ever Get Weirdly Sentimental During Runs?”3, highlighted another phenomena: endurance runners were found to have elevated levels of oxytocin.  Peter Sagal, a 3:09 marathoner and the host of NPR’s Wait, Wait…Don’t Tell Me!, refers to a study from 2008 where it is speculated that increased oxytocin levels play a role in fluid homeostasis along with other peptide hormones such as vasopressin and possibly BNP.4 Oxytocin has also received mainstream press coverage recently in The New York Times in 2012. The article, “The ‘Love Hormone’ as Sports Enhancer ”5,speculated on oxytocin’s role in promoting social bonding in team sports activities amongst the players. A peer-reviewed paper referenced in this The New York Times article describes the outcome of making an emotional connection to soccer teammates during a penalty kick shootout in response to oxytocin.6

For those interested in oxytocin, or more generally, the junction of exercise and the body’s chemistry, these references and several others7-9 are worth reading.
