Why Endurance Athletes Feel Less Pain

Although looking into a e-book on stamina a several decades ago, I interviewed a German scientist named Wolfgang Freund who had just lately done a review on the pain tolerance of extremely-stamina runners. Subjects in the review had to hold their hands in ice drinking water for as prolonged as attainable. The non-athlete regulate team lasted an regular of 96 seconds just before providing up each and every one one of the runners, in distinction, designed it to the a few-minute security slash-off, at which stage they rated the pain as a mere six out of ten on regular.

The effects have been steady with former analysis showing that athletes can tolerate extra pain than non-athletes. But not all sports impose the same calls for, Freund pointed out: “Maradona, at least, had the illusion that a outstanding soccer player did not need to have to suffer.” As a runner myself, I liked the implication that stamina athletes are uniquely tough, so I fortunately integrated that estimate in my e-book. But is it really true?

As it occurs, researchers at Norway’s University of Tromsø tackled particularly that dilemma, along with quite a few other fascinating ones, in a the latest review in Frontiers in Psychology. They in comparison seventeen countrywide-stage soccer players with fifteen elite stamina athletes (cross-country skiers and runners, also “competing at the best countrywide stage in Norway”) and 39 non-athlete controls in a few pain exams. They also administered a series of psychological questionnaires to discover what characteristics are linked with increased pain tolerance.

The initially pain exam was the same one made use of in Freund’s review: dunking the hand in scarcely-earlier mentioned-freezing drinking water for as prolonged as attainable (all over again with a a few-minute slash-off, though the topics weren’t instructed about it in advance). On regular, the stamina athletes lasted 179.sixty seven seconds (meaning virtually all of them designed it to a few minutes, with the exception of one person who stopped five seconds early). The regulate team averaged 116.seventy eight seconds, and the outstanding soccer players just 113.90 seconds.

This was particularly what the researchers expected. Soon after all, embracing open-finished pain is particularly what stamina athletes do each and every day in schooling, so it makes feeling that they have a higher pain tolerance. But pain threshold—the stage at which a feeling goes from uncomfortable to painful—might be distinct. Soccer players, like other group sport athletes, encounter briefer spikes of pain linked with “short bouts of supramaximal intensity and receiving blows from opponents or the ball,” the researchers stage out. As a outcome, they hypothesized that the encounter of this extra extreme pain would give soccer players a bigger pain threshold than stamina athletes.

To exam pain threshold, they applied a heated aluminum thermode to the interior forearm of the topics, starting at 90 levels Fahrenheit and slowly raising to a optimum of 126 levels. The topics had to push a button when the feeling improved from heat to pain, and this process was repeated five occasions. This time, contrary to their speculation, the soccer players and stamina athletes have been primarily the same, at 117.seven and 118.two levels, and both equally have been substantially bigger than the non-athletes at 115.8 levels. (These quantities are from the initially exam when the exam was repeated a second time, the quantities have been somewhat bigger but the sample was the same.)

The 3rd exam looked at still another part of pain response, pain sensitivity. Although pain is fundamentally a subjective encounter, pain sensitivity attempts to quantify how intensely you come to feel a specified stimulus. It is of course linked to both equally threshold and tolerance, but it is not similar: one person could possibly come to feel pain extremely intensely but nonetheless be prepared to tolerate it for extended than somebody else who feels it much less intensely. To measure sensitivity, the temperature of the heated thermode was ramped up to 117.5 levels for thirty seconds, and contributors had to fee their pain on a scale of to one hundred. The researchers expected no change involving the soccer players and the stamina athletes. In its place, the regular pain scores for the initially exam have been forty five.5 out of one hundred for the stamina athletes, 51.9 for the soccer players, and fifty nine.4 for the non-athletes. In the second exam, the scores have been 37.9, forty five.4, and 53.seven. The discrepancies aren’t statistically sizeable, but there’s a rather suggestive pattern.

There are two big thoughts in this article. One is why the a few teams have distinct perceptions of pain the other is no matter if the athletes have been born with these discrepancies, or no matter if they obtained them as a outcome of their schooling. The most broadly held perspective is that the big discrepancies are psychological, as opposed to some form of physiological dulling of pain sensors. In this review, the researchers assessed the subjects’ “Big Five” psychological characteristics (openness, conscientiousness, extraversion, agreeableness, and neuroticism), and gave different questionnaires to assess grit and dread of pain.

The effects are a little convoluted, specified that there are seven psychological characteristics, a few teams, and a few pain notion outcomes. Equally grit and conscientiousness had a little bit of predictive energy on some outcomes, which isn’t astonishing due to the fact some critics argue that grit is generally just a fancy repackaging of the more mature thought of conscientiousness. The one psychological characteristic that predicted all a few outcomes was dread of pain, which makes feeling. But there have been no statistically sizeable discrepancies involving the a few teams in their regular dread of pain scores, though the stamina team seemed to have somewhat greater (i.e. much less fearful) scores. That means it cannot be the primary purpose the a few teams scored differently on the pain exams.

As for the second dilemma on mother nature versus nurture, this review cannot solution it. There have been some hints in former experiments that pain tolerance is a trainable trait, and that stamina schooling is one way of maximizing it. On the other hand, I’d be surprised if there isn’t some aspect of athletes getting “chosen by their sport” in aspect based mostly on pre-present psychological attributes like willingness to suffer. The new review provides dread of pain to the record of applicable psychological attributes, alongside others from former analysis like tendency to catastrophize (poor) and ability to ignore detrimental emotions (excellent).

It looks to me that we’re not likely to find one neat mental trick that distinguishes pain gluttons from pain avoiders. In its place, profitable athletes most likely have an array of distinct mental techniques for working with distinct types of pain in distinct contexts. Teasing out the very best techniques is a terrific subject for upcoming analysis. But to be truthful, it is all a digression from the primary stage I needed to emphasize from this paper—which is that Wolfgang Freund was proper.
