Smile

Grinner’s Circle was the title of an article in the December 10, 2017 The New York Times. The article mentioned that Eliud Kipchoge periodically smiled during the final miles of his fastest ever two hours 25 seconds marathon. Researchers from Ulster University and Swansea University ran an experiment related to running economy, which is a measure of how much oxygen is used to stride at a given speed. 24 men and women volunteers were studied. They had to wear a facial mask that measured their respiration while they ran on a treadmill till they were exhausted. They then rated how they felt and described strategies they used to keep going, ignoring their bodies, discomfort. In a subsequent lab visit, each volunteer completed a series of four 6 minute runs during which they were assigned. 4 different approaches 1.smile continuously, but sincerely 2. Relax r upper body 3. Frown 4. Use their normal mental techniques. Findings: as a group, the runner’s economy was as much as 2.78% more efficient smiling than during the other trials. A disclaimer per the following commentary. I did not read the original study. Therefore, my critique may be suspect. 2016 Olympic marathon winner Kipchoge’s strategies, training, genetics, etc. would paint a more complete picture of perhaps the greatest marathoner in the modern area. Smiling for him, might be related to the fact that he was running the fastest marathon ever and he knew it. The variables, 24 volunteers was not a random sample, which limits the generalizations; running six minutes on a treadmill limits the findings to running six minutes on a treadmill; and the 2.78% differences may or may not have statistical significance compared to chance. As running performance varies day-to-day, the initial baseline measure of running on a treadmill to exhaustion may or may not be an accurate baseline measure. Further, running track or on the trail is significantly different than running on a treadmill. We can’t conclude that the six minute treadmill measure of running economy or efficiency equates to running any distance longer or shorter in time than 6 minutes. Performing running and smiling sincerely is artificial and difficult to achieve. For instance, when running on the trail, one has to be aware of tree roots, fallen trees, rocks and other hazards. These hazards tend to interfere with smiling. Setting up a field study is difficult, but would more likely lead to more sound conclusions. However, grinning during your runs certainly can’t hurt you. It may even work as a placebo. There’s nothing wrong with employing a placebo if it improves your running. God knows that we have many thoughts going through our mind when running at marathon or ultramarathon distances. Telling yourself to smile, if nothing else, makes you look like you’re enjoying yourself. Smile and keep moving!
