The research has taken into account the position of athletes during skating and the problem of fatigue and pain in these muscles. The research covered involved eight female athletes of the Polish National Team in short track, which had been prepared to the Olympic Games in PyeongChang. The surface electromyography (sEMG) system was used to measure fatigue of right and left gluteus maximus muscles, in the modified Biering\u2013Sorensen test. The test was conducted five times during the training: before training, after warmup, and after each of 3 series of the endurance training. Comparing the mean frequency of the surface electromyography power spectrum of the test, statistically significant reduction of the average frequency value of the right muscle from 55.61\u2009\u00b1\u20097.08 to 48.64\u2009\u00b1\u20094.48\u00a0Hz and left muscle from 58.78\u2009\u00b1\u20094.98 to 53.18\u2009\u00b1\u20094.62\u00a0Hz was reported, which prove the muscle fatigue. In subsequent series tests, the sEMG signal frequency of begin decrease more than the end of the each measurement, which determines the fatigue threshold. The size of the d Cohen effect in fatigue drops along with subsequent five tests during the training. Skaters has higher frequency reduction of the right lower limb, which indicates its greater fatigue during skateing. The fatigue and asymmetry in muscle observed in short-track has implications for training and performance.<\/jats:p>","DOI":"10.1038\/s41598-020-71052-4","type":"journal-article","created":{"date-parts":[[2020,8,26]],"date-time":"2020-08-26T10:13:57Z","timestamp":1598436837000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Training induced fatigability assessed by sEMG in Pre-Olympic ice-skaters"],"prefix":"10.1038","volume":"10","author":[{"given":"Pawe\u0142","family":"Pakosz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariusz","family":"Konieczny","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,8,26]]},"reference":[{"key":"71052_CR1","doi-asserted-by":"publisher","first-page":"765","DOI":"10.1097\/00005768-199606000-00016","volume":"28","author":"KW Rundell","year":"1996","unstructured":"Rundell, K.
