Do sports products really enhance your workout? Maybe not
By Alexandra Sifferlin | Time.com
" . . . researchers at the University of Oxford looked at advertisements for sports drinks, oral supplements, footwear, clothing and fitness devices . . . in 100 general interest magazines and the top 10 sport and fitness magazines in the U.K. and the U.S. The team also searched the websites of any product making claims to enhance athletic performance or improve recovery, seeking references for scientific studies supporting these claims."
"After sifting through the available references, the
researchers discarded half for being unfit for scientific appraisal; they pointed to books without clinical studies, nonexistent studies, conference abstracts or online surveys without data, or nonhuman studies, such as a study of the effects of different diets on rat metabolism published in 1930.
Of the 74 studies that could be evaluated, the team found that only three were of high quality and low risk for bias. Notably, all three reported no significant effects of the intervention studied."
