Among promising non-pharmacological therapies, physical exercise is an attractive, cheap, accessible and innocuous method; beyond other health benefits. However, its highly variable therapeutic effect and incompletely understood underlying mechanisms (plausibly involving the GABAergic neurotransmission) require further research. This case\u2013control study aimed to investigate the impact of long-lasting intensive endurance sport practice (\u22657\u2009h\/week for the last 6\u2009months at the time of the experiment) on the response to experimental cold-induced pain (as a suitable chronic pain model), assuming that highly trained individual would better resist to pain, develop advantageous pain-copying strategies and enhance their GABAergic signaling. For this purpose, clinical pain-related data, response to a cold-pressor test and high-density EEG high (H\u03b2) and low beta (L\u03b2) oscillations were documented. Among 27 athletes and 27 age-adjusted non-trained controls (right-handed males), a category of highly pain-resistant participants (mostly athletes, 48.1%) was identified, displaying lower fear of pain, compared to non-resistant non-athletes. Furthermore, they tolerated longer cold-water immersion and perceived lower maximal sensory pain. However, while having similar H\u03b2 and L\u03b2 powers at baseline, they exhibited a reduction between cold and pain perceptions and between pain threshold and tolerance (respectively \u221260% and\u2009\u2212\u20096.6%; \u2212179.5% and\u2009\u2212\u20095.9%; normalized differences), in contrast to the increase noticed in non-resistant non-athletes (+21% and\u2009+\u200914%; +23.3% and\u2009+\u200913.6% respectively). Our results suggest a beneficial effect of long-lasting physical exercise on resistance to pain and pain-related behaviors, and a modification in brain GABAergic signaling. In light of the current knowledge, we propose that the GABAergic neurotransmission could display multifaceted changes to be differently interpreted, depending on the training profile and on the homeostatic setting (e.g., in pain-free versus chronic pain conditions). Despite limitations related to the sample size and to absence of direct observations under acute physical exercise, this precursory study brings into light the unique profile of resistant individuals (probably favored by training) allowing highly informative observation on physical exercise-induced analgesia and paving the way for future clinical translation. Further characterizing pain-resistant individuals would open avenues for a targeted and physiologically informed pain management.<\/jats:p>","DOI":"10.3389\/fnins.2023.1287233","type":"journal-article","created":{"date-parts":[[2024,1,15]],"date-time":"2024-01-15T04:17:00Z","timestamp":1705292220000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Response to experimental cold-induced pain discloses a resistant category among endurance athletes, with a distinct profile of pain-related behavior and GABAergic EEG markers: a case\u2013control preliminary study"],"prefix":"10.3389","volume":"17","author":[{"given":"Franziska","family":"Peier","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Mouthon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"De Pretto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joelle Nsimire","family":"Chabwine","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2024,1,15]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"728","DOI":"10.1016\/j.bbadis.2018.08.019","article-title":"Impact of exercise training on cardiovascular disease and risk","volume":"1865","author":"Adams","year":"2019","journal-title":"Biochim.
