Twenty male judo athletes participated in this study (age: 20.65 \u00b1 1.22 years, weight: 84.17 \u00b1 28.45 kg). Participants were assessed for CMJperformance changes before, immediately after (0 h), 12 h after, and 24 h after judo training (JT) using unloaded CMJ(CMJunloaded) and loaded CMJ(CMJloaded). All the jumps were performed on a force plate, and the force\u2013time curves were collected for further analysis. Respondents\u2019 perceptions were evaluated using the modified rating of perceived exertion (mRPE) before, after (0 h), 12 h, and 24 h after JT. CMJparameters were analyzed at four measured points using a one-way repeated analysis of variance. Effect sizes (ES) and percentage changes before versus 24 h after JT were calculated for comparison. Associations between the CMJparameters and mRPE were analyzed using the Pearson product\u2013moment correlation. The ratio of flight time to contact time significantly decreased, whereas the eccentric duration, concentric duration, and total duration significantly increased (p &lt; 0.05) in both CMJs 24 h after JT. Compared with CMJunloaded, CMJloaded had a significantly lower (p &lt; 0.05) flight time, jump height, peak velocity, and peak power. The mRPE and CMJloaded peak velocity showed moderate- to high-level negative correlation results both 0 and 24 h after training (r = \u22120.543, p &lt; 0.05; r = \u22120.479, p &lt; 0.05). In this study, we only observed the effect of fatigue on the neuromuscular (NM) system 24 h after JT. CMJloaded height may help to better determine fatigue state compared with CMJunloaded. According to the results, the neuromuscular effects of fatigue were not observed until 24 h after a single high-intensity training. Therefore, when arranging high-intensity special training or strength and conditioning training, one should reduce the volume of training appropriately to avoid fatigue accumulation and reduce the risk of sports injuries.<\/jats:p>","DOI":"10.3390\/ijerph192417008","type":"journal-article","created":{"date-parts":[[2022,12,19]],"date-time":"2022-12-19T05:55:43Z","timestamp":1671429343000},"page":"17008","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Effect of Acute Judo Training on Countermovement Jump Performance and Perceived Fatigue among Collegiate Athletes"],"prefix":"10.3390","volume":"19","author":[{"given":"Chien-Chun","family":"Chang","sequence":"first","affiliation":[{"name":"Graduate Institute of Athletics and Coaching Science, National Taiwan Sport University, Taoyuan 333, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tzu-Yi","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Athletic Training and Health, National Taiwan Sport University, Taoyuan 333, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chia-Luan","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Sports Training Science-Combats, National Taiwan Sport University, Taoyuan 333, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pi-Yen","family":"Ho","sequence":"additional","affiliation":[{"name":"Department of Sports Training Science-Combats, National Taiwan Sport University, Taoyuan 333, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chieh-Ying","family":"Chiang","sequence":"additional","affiliation":[{"name":"Department of Sports Training Science-Combats, National Taiwan Sport University, Taoyuan 333, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"367","DOI":"10.1123\/ijspp.5.3.367","article-title":"Neuromuscular, endocrine, and perceptual fatigue responses during different length between-match microcycles in professional rugby league players","volume":"5","author":"McLean","year":"2010","journal-title":"Int.
