Methods: Eight semi-professional women\u2019s volleyball players (height = 1.63 \u00b1 0.08 m; weight = 66.67 \u00b1 4.74 kg) voluntarily participated in this study. A randomized crossover design was implemented where players underwent caffeine and placebo conditions. In the caffeine condition, participants consumed 5 mg\/kg of caffeine based on their body weight before acute training. The evaluations were performed over two weeks of training. In both conditions, the countermovement jump, repeated jumps for 15 s, and handgrip tests were performed. The change of direction was assessed using the 505 test. Well-being was also assessed with a wellness questionnaire. A repeated measures ANOVA and correlation analysis were performed. Results: The repeated measures ANOVA revealed a main effect of supplementation (F (1.7) = 8.41, p = 0.02, \u03b72 = 0.54) across the training week on physical performance. Additionally, there was a positive effect on perceived fatigue (F (1.7) = 7.29, p = 0.03, \u03b72 = 0.51). Conclusions: Caffeine improved performance and fatigue parameters over one week of training. Further research is needed on women, focusing on physical performance and wellbeing, especially during intense periods.<\/jats:p>","DOI":"10.3390\/nu16010029","type":"journal-article","created":{"date-parts":[[2023,12,21]],"date-time":"2023-12-21T03:36:17Z","timestamp":1703129777000},"page":"29","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["The Effect of Caffeine Supplementation on Female Volleyball Players\u2019 Performance and Wellness during a Regular Training Week"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3185-3615","authenticated-orcid":false,"given":"Jes\u00fas","family":"Siquier-Coll","sequence":"first","affiliation":[{"name":"Department of Communication and Education, Universidad Loyola Andaluc\u00eda, 41704 Dos Hermanas, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriel","family":"Delgado-Garc\u00eda","sequence":"additional","affiliation":[{"name":"SER Research Group, Department of Physical Activity and Sport Sciences, Center of Higher Education Alberta Gim\u00e9nez, Affiliated to Pontifical University of Comillas, 07013 Palma, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8593-4037","authenticated-orcid":false,"given":"Fulgencio","family":"Soto-M\u00e9ndez","sequence":"additional","affiliation":[{"name":"SER Research Group, Department of Physical Activity and Sport Sciences, Center of Higher Education Alberta Gim\u00e9nez, Affiliated to Pontifical University of Comillas, 07013 Palma, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1268-8098","authenticated-orcid":false,"given":"Antonio","family":"Li\u00f1\u00e1n-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Department of Nursing, Faculty of Health Sciences, Melilla Campus, University of Granada, 52005 Melilla, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raquel","family":"Garc\u00eda","sequence":"additional","affiliation":[{"name":"Department of Nursing, Faculty of Health Sciences, University of Granada, 18071 Granada, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1480-7521","authenticated-orcid":false,"given":"Francisco","family":"Gonz\u00e1lez-Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sports, Faculty of Sport Sciences, University of Granada, 18071 Granada, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"477","DOI":"10.1136\/bjsm.2003.005785","article-title":"A One Season Prospective Cohort Study of Volleyball Injuries","volume":"38","author":"Verhagen","year":"2004","journal-title":"Br.
