Internal training load (ITL) was measured using the session rating of perceived exertion (sRPE), whereas external training load (ETL) was assessed with an inertial measurement unit capturing jumps and energy. Repeated measures analysis of variance (RMANOVA) and correlation analysis were conducted.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The RMANOVA revealed significant differences in monotony and strain of ITL, as well as in the monotony of jumps and energy. Significant correlations were found between ITL and ETL metrics, with higher sRPE and daily ITL associated with increased jumps and energy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The findings highlight the interrelationships between internal and external load metrics, with higher perceived exertion and daily training loads associated with increased external workload, particularly in jump frequency and energy. In addition, training monotony and strain fluctuated across microcycles, with notable increases observed as the competition approached. These results emphasize the importance of systematically monitoring both internal and external training loads, including monotony and strain, to better understand workload dynamics and guide training adjustments.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Relevance:<\/jats:title>\n                    <jats:p>The findings provide practical insights for coaches on how to balance training intensity and volume to enhance performance and prevent overtraining and injuries.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/19417381251334641","type":"journal-article","created":{"date-parts":[[2025,6,9]],"date-time":"2025-06-09T02:15:31Z","timestamp":1749435331000},"page":"1183-1191","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Monitoring Internal and External Training Loads in Female Artistic Roller Skating: A Longitudinal Study"],"prefix":"10.1177","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2441-9167","authenticated-orcid":false,"given":"Andr\u00e9","family":"Rebelo","sequence":"first","affiliation":[{"name":"CIDEFES, Centro de Investiga\u00e7\u00e3o em Desporto, Educa\u00e7\u00e3o F\u00edsica e Exerc\u00edcio e Sa\u00fade, Universidade Lus\u00f3fona, Lisboa, Portugal"},{"name":"COD, Center of Sports Optimization, Sporting Clube de Portugal, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0825-4032","authenticated-orcid":false,"given":"Diogo V.","family":"Martinho","sequence":"additional","affiliation":[{"name":"Research Unit for Sport and Physical Activity, Faculty of Sport Sciences and Physical Education, University of Coimbra, Coimbra, Portugal"},{"name":"Laboratory of Robotics and Engineering Systems (LARSYS), Interactive Technologies Institute (ITI), Funchal, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-0096-9917","authenticated-orcid":false,"given":"In\u00eas G.","family":"Pires","sequence":"additional","affiliation":[{"name":"CIDEFES, Centro de Investiga\u00e7\u00e3o em Desporto, Educa\u00e7\u00e3o F\u00edsica e Exerc\u00edcio e Sa\u00fade, Universidade Lus\u00f3fona, Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ricardo","family":"Lima","sequence":"additional","affiliation":[{"name":"Escola Superior de Desporto e Lazer, Instituto Polit\u00e9cnico de Viana do Castelo, Viana do Castelo, Portugal"},{"name":"Sport Physical Activity and Health Research and Innovation Center (SPRINT), Melga\u00e7o, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F\u00e1bio Y.","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Research Center in Sports Sciences, Health Sciences and Human Development (CIDESD), University Institute of Maia (ISMAI), Maia, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,6,8]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2005.018341"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.2165\/11317780-000000000-00000"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2009.069476"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.47197\/retos.v48.96010"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1123\/ijspp.2016-0423"},{"key":"e_1_3_2_7_2","volume":"2","author":"Cohen J.","year":"1988","unstructured":"Cohen J.
