Data were obtained over three consecutive days during the preparation camp for the FIFA Beach Soccer World Cup Russia 2021. The session rating of perceived exertion (s-RPE) and external training load metrics using global positioning system (GPS) were recorded. Eleven players reported perceived well-being (sleep quality, fatigue, muscle soreness and stress) using a Likert scale (Hooper Index) before breakfast. Within-subjects correlation coefficients between workload and well-being were calculated. Workload metrics and perceived well-being indices were significantly lower on day three than on days one and two. The Hooper Index presented a very large positive correlation with s-RPE (r = 0.86 [0.67, 0.94], 95% confidence interval, CI), exposure time (r = 0.88 [0.71, 0.95]), total distance (r = 0.83 [0.60, 0.93]), high-speed distance (r = 0.77 [0.50, 0.91]), and number of sprints (r = 0.75 [0.47, 0.90]). Sleep quality presented a moderate to large positive correlation with s-RPE (r = 0.51 [0.11, 0.77]), exposure time (r = 0.50 [0.10, 0.76]), high-speed distance (r = 0.53 [0.15, 0.78]), number of sprints (r = 0.62 [0.28, 0.83]) and total distance (r = 0.41 [0.18, 0.78]). Fatigue presented a large to very large positive correlation with s-RPE (r = 0.85 [0.66, 0.94]), exposure time (r = 0.90 [0.78, 0.96]), total distance (r = 0.86 [0.68, 0.94]), high-speed distance (r = 0.65 [0.31, 0.84]) and number of sprints (r = 0.56 [0.18, 0.79]). Muscle soreness presented a large to very large positive correlation with s-RPE (r = 0.79 [0.56, 0.91]), exposure time (r = 0.83 [0.62, 0.93]), total distance (r = 0.81 [0.59, 0.92]), high-speed distance (r = 0.75 [0.47, 0.89]) and number of sprints (r = 0.59 [0.22, 0.81]). Overall, workload presented a meaningful correlation with perceived well-being indices in elite male beach soccer players during a training camp. These findings suggest that workload metrics and perceived well-being indices can be implemented into the daily routine of an elite beach soccer team, which may assist coaches, sports scientists, and practitioners in better preparing players for beach soccer competitions.<\/jats:p>","DOI":"10.3390\/ijerph19106209","type":"journal-article","created":{"date-parts":[[2022,5,20]],"date-time":"2022-05-20T04:27:22Z","timestamp":1653020842000},"page":"6209","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Associations between Training Load and Well-Being in Elite Beach Soccer Players: A Case Report"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8225-8667","authenticated-orcid":false,"given":"J\u00falio A.","family":"Costa","sequence":"first","affiliation":[{"name":"Portugal Football School, Portuguese Football Federation, FPF, 1495-433 Cruz Quebrada, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5515-3694","authenticated-orcid":false,"given":"Pedro","family":"Figueiredo","sequence":"additional","affiliation":[{"name":"Portugal Football School, Portuguese Football Federation, FPF, 1495-433 Cruz Quebrada, Portugal"},{"name":"CIDEFES, Universidade Lus\u00f3fona, Campo Grande, 1749-024 Lisboa, Portugal"},{"name":"Research Center in Sports Sciences, Health Sciences and Human Development (CIDESD), 5001-801 Vila Real, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto","family":"Prata","sequence":"additional","affiliation":[{"name":"Portugal Football School, Portuguese Football Federation, FPF, 1495-433 Cruz Quebrada, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tiago","family":"Reis","sequence":"additional","affiliation":[{"name":"Portugal Football School, Portuguese Football Federation, FPF, 1495-433 Cruz Quebrada, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joana F.","family":"Reis","sequence":"additional","affiliation":[{"name":"Portugal Football School, Portuguese Football Federation, FPF, 1495-433 Cruz Quebrada, Portugal"},{"name":"Laboratory of Physiology and Biochemistry of Exercise, Faculdade de Motricidade Humana, Universidade de Lisboa, 1495-751 Lisboa, Portugal"},{"name":"Interdisciplinary Center for the Study of Human Performance (CIPER), Faculdade de Motricidade Humana, Universidade de Lisboa, 1495-751 Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu\u00eds","family":"Nascimento","sequence":"additional","affiliation":[{"name":"Portugal Football School, Portuguese Football Federation, FPF, 1495-433 Cruz Quebrada, Portugal"},{"name":"Polytechnic Institute of Leiria, 2411-901 Leiria, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1301-1078","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Brito","sequence":"additional","affiliation":[{"name":"Portugal Football School, Portuguese Football Federation, FPF, 1495-433 Cruz Quebrada, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,20]]},"reference":[{"key":"ref_1","first-page":"98","article-title":"Heart Rate and Motion Analysis by GPS in Beach Soccer","volume":"9","author":"Castellano","year":"2010","journal-title":"J.
