20.500.12556/RUL-145187 Effect of six-week speed endurance training on peripheral fatigue (1) Speed endurance training (inducing a high blood lactate concentration) delays excitation–contraction coupling impairment, thus providing more space for high-frequency fatigue to occur in the early stage of maximal concentric actions. This study aimed to test the hypothesis that the maintenance type of speed endurance training may shift peripheral fatigue from low-frequency to high-frequency fatigue after the 15 s long Wingate test. (2) Six students of physical education performed the corresponding training for six weeks. Before and after this period, they were tested for low- and high-frequency fatigue after the 15 s long Wingate test; additionally, their blood lactate concentrations, maximal cycling power, work, fatigue index, and muscle twitch responses were also tested. (3) The training increased the maximal cycling power and work (p < 0.001 and p < 0.01, respectively) with minor changes in the mean fatigue index and blood lactate concentration (both p > 0.05). Low-frequency dominant fatigue before the training showed a trend toward high-frequency dominant fatigue after the training (p > 0.05). (4) The results showed that the 15 s Wingate test failed to induce significant high-frequency fatigue. Even though it displayed a substantial fatigue index, the changes in favor of high-frequency fatigue were too small to be relevant. sport training muscle fatigue peripheral fatigue Wingate test šport usposabljanje mišična utrujenost periferna utrujenost Wingate test true false true Angleški jezik Slovenski jezik Članek v reviji 2023-04-12 15:25:22 2023-04-12 15:25:23 2023-04-13 03:31:26 0000-00-00 00:00:00 2022 0 0 9 str. iss. 17, art. 10841 Vol. 19 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.01 1660-4601 10.3390/ijerph191710841 119787011 ijerph-19-10841.pdf ijerph-19-10841.pdf 1 6887808D8961D7BD6DCF97C9ECDB6050 ef902fe218e7f2f5ed6b85daa6750c43a0c7e0d3a9cba538a1ef3f88ff913601 213840eb-d936-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167895 https://www.mdpi.com/1660-4601/19/17/10841 1 55569f89-d935-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167894 Fakulteta za šport 0 0 0
