Four years ago, while watching the 2012 Olympic Games, I noticed a lot of athletes wearing colored strips in various patterns on their body. I discovered that these strips were called kinesiotape, and they were used to enhance performance, reduce injury, and help muscles recover more quickly. I also discovered that these claims for kinesiotape were complete nonsense.
This year at the 2016 Rio Olympics, I (and many other people, judging by my e-mails) noticed that many athletes, especially the swimmers, had what appeared to be circular bruises on their backs, shoulders, and sometimes elsewhere on their body. I immediately recognized the telltale signs of cupping, a pseudoscientific treatment that is part of traditional Chinese medicine (TCM).
Pseudoscience in sports
What both kinesiotape and cupping have in common, other than a lack of evidence that they work, is that they are immediately visible to the casual observer (another example would be the hologram bracelets that were once common). This led me to suspect that they represent only the tip of the nonsense iceberg at the Olympics. What other worthless treatments are athletes using that don’t leave visible marks on their skin?
