The 100 Most Influential Studies in Sports Medicine

A single measure of the affect of a scientific strategy is how frequently it will get cited by other scientists. The top rated-cited paper of all time, in accordance to a 2014 assessment by Character, has now been cited by 344,007 other scientific article content because its publication in 1951. (The subject matter? You’d under no circumstances guess, for factors we’ll get into down below.) Researchers’ work prospective clients are motivated by their h-index, a measure that rewards getting a large variety of greatly cited papers (and most likely, though no one would actually admit it, by their Kardashian index, which compares their cumulative citations to the variety of Twitter followers they have).

You can also use equivalent methods to evaluate full fields, which is what a new review led by Omeet Khatra of the College of British Columbia makes an attempt for athletics and workout drugs. In the Orthopaedic Journal of Sporting activities Medication, Khatra and his colleagues put together a listing of the 100 article content with the most citations in the subject, providing a snapshot of the influence of both equally individual papers and broader developments. There are a bunch of appealing conclusions, but most likely the most telling is this: only one of the 100 papers is a randomized controlled trial, which is the gold-common variety of experimental proof.

The Area

A single key caveat for this assessment is that the boundaries of athletics and workout drugs are fairly hazy. Khatra’s definition contains taking care of athletics injuries, improving athletic efficiency, and the use of workout to increase health and fitness. That’s really wide, but the process utilised to discover top rated papers was a minimal a lot more idiosyncratic. They begun by determining a listing of 46 journals targeted on athletics and workout drugs, and then recognized the 100 most-cited article content from within those journals.

That suggests considerable papers posted in non-expert journals never show up on the listing. A.V. Hill’s original 1923 study on VO2 max was posted in the Quarterly Journal of Medication Karlman Wasserman’s 1964 paper on the anaerobic threshold was posted in the American Journal of Cardiology. In actuality, you’d assume that the most ground-breaking conclusions are the most most likely to make it into generalist journals like Character and Science (exactly where, for illustration, a traditional 1937 paper on the aerobic power of environment report-location runners was posted).

So it is not a in depth listing, but it even now addresses a massive portion of the subject. It’s dominated by Medication & Science in Sporting activities & Exercising, the flagship journal of the American School of Sporting activities Medication, which contributes no less than forty nine of the papers. Future on the listing are the American Journal of Sporting activities Medication, with 18, and Sporting activities Medication, with seven. The oldest paper on the listing is from 1973, reflecting the field’s rather new emergence as a distinctive self-control: MSSE, for illustration, was only released in 1969.

The Winner

Topping the listing with seven,228 citations was Gunnar Borg’s 1982 paper, “Psychophysical bases of perceived exertion.” Borg is the male who advanced the principle of a subjective scale of perceived effort, which at first ran from six to 20, whilst there’s a a lot more logical modified variation that runs from zero to 10. He begun acquiring this strategy in the nineteen sixties, but the 1982 English-language paper is the one that will get cited anytime folks talk about perceived effort. (Yet another one of Borg’s papers on the subject matter, from 1973, demonstrates up at forty eighth on the listing.)

You may well not believe that inquiring folks to assign a variety to how difficult they’re doing work is a major scientific breakthrough. But Borg’s work has experienced a huge influence. He argued that his scale is “the single most effective indicator of the diploma of actual physical pressure,” integrating alerts from the muscle groups, lungs, heart, and mind. In the final two decades, a lot more and a lot more scientists have taken that argument significantly as they’ve tried to make clear the brain’s function in deciding our actual physical boundaries, and also as a sensible resource for guiding schooling. Base line: I’d say Borg’s paper is a deserving champion.

The Themes

The largest group of papers on the listing concentration on methodological equipment: how to operate a VO2 max exam, how to work out physique composition, how to calibrate your pedometers and accelerometers, what validated questionnaires to use to check with your topics about their workout behavior, and so on. That’s also what’s observed in other fields: the all-time most cited paper that I talked about at the top rated is a methods paper on “protein measurement with the folin phenol reagent.”

Techniques papers might not sound all that remarkable, but they can undoubtedly be controversial. Many of the papers on the listing concentration on figures, which includes the variety nine paper, from 2008, by Will Hopkins and colleagues: “Progressive figures for reports in athletics drugs and workout science.” That method to figures is designed to tease out subtle efficiency results in reports with smaller sample dimensions. But it has appear underneath rigorous criticism, most notably next a 2018 report in FiveThirtyEight by Christie Aschwanden arguing that it is a lot more most likely to generate phony-optimistic conclusions than common statistical methods.

Yet another massive bucket is formal suggestions, largely the ones issued by the American School of Sporting activities Medication on topics which includes resistance schooling, performing exercises with cancer, hydration, fat loss, blood strain, and exercise routines for more mature grownups. These are valuable overviews to cite in the introduction to an report when you want to back again up normal statements like “exercise is great for you” or whatever, but they’re not particularly ground-breaking.

Just after that, it is a lot more of a combined bag. The most well-liked element of the anatomy is the knee, which is the concentration of fifteen papers, largely relating to ACL injuries. Future is the mind, which features in 3 papers on concussion in activity. Two other themes that rack up numerous mentions: the enduring mystery of delayed-onset muscle mass soreness, and the rising health and fitness scourge of far too much sitting.

There are 3 papers on the physiology of soccer, one on the biomechanics of baseball pitching, and one on Hakan Alfredson’s famed heel-drop protocol for Achilles tendinosis, which squeaks in at 98th position. (Funny backstory: Alfredson is an orthopedic surgeon who experienced Achilles issues back again in the 1990s. When his boss refused to give him time off for operation simply because the condition was not severe enough, he made the decision to aggravate his Achilles with painful heel drops—but unintentionally healed himself.)

The Proof

I talked about at the top rated that only one of the reports on the listing is a randomized controlled trial, which means that topics had been randomly assigned to either get either an intervention or a placebo. Rather, most of the experimental papers use decreased amounts of proof these types of as cohort reports and circumstance collection, neither of which use randomization or command groups. The most important single category, with 38 papers, is narrative opinions, which survey the outcomes of numerous reports on a subject matter but never pool them into one massive meta-assessment.

I believe most athletics scientists would concur that the subject wants a lot more randomized trials, together with other methodological advancements like greater matter groups and a lot more subtle statistical analyses. But the faults in the top rated-100 listing probably aren’t particular to athletics science. Watson and Crick’s discovery of the framework of DNA and Einstein’s principle of normal relativity never make their respective lists either: the most important breakthroughs become textbook materials that doesn’t even need a quotation. “If citations are what you want,” Yale College chemist Peter Moore advised Character, “devising a process that tends to make it achievable for folks to do the experiments they want at all, or a lot more effortlessly, will get you a ton additional than, say, exploring the solution of the Universe.”
