The correlations and contributions of individual physical health parameters to the tasks of firefighting would enable firefighters to focus on the effects of specific physical conditions during their physical training programs. Therefore, the purpose of the present study was to identify the relationships between various physical health parameters (weight, maximum oxygen uptake, body fat percentage, upper body muscular power and lower body muscular power) and performance on simulated firefighting ability tasks, which included a set of seven tasks (rope climb, run 200 m round trip with load, 60 m carrying a ladder, climb stairs with load, evacuation of 400 m with supplies, run 5 km with an air respirator, run 100 m with the water hose). Through use of a partial least-squares regression (PLSR) algorithm to analyze the linear correlation, we revealed the change in various training performances of specific ability tests with physical fitness parameters. The present study demonstrated significant relationships among physical health parameters and performance on simulated firefighting ability tasks, which also represent that those parameters contributed significantly to the model\u2019s predictive power and were suitable predictors of the simulated firefighting tasks score.<\/jats:p>","DOI":"10.3390\/ijerph17207689","type":"journal-article","created":{"date-parts":[[2020,10,21]],"date-time":"2020-10-21T10:14:22Z","timestamp":1603275262000},"page":"7689","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Relationship between Firefighter Physical Fitness and Special Ability Performance: Predictive Research Based on Machine Learning Algorithms"],"prefix":"10.3390","volume":"17","author":[{"given":"Datao","family":"Xu","sequence":"first","affiliation":[{"name":"Faculty of Sports Science, Ningbo University, Ningbo 315211, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7438-6290","authenticated-orcid":false,"given":"Yang","family":"Song","sequence":"additional","affiliation":[{"name":"Faculty of Sports Science, Ningbo University, Ningbo 315211, China"},{"name":"Doctoral School of Safety and Security Sciences, Obuda University, 1034 Budapest, Hungary"},{"name":"Faculty of Engineering, University of Szeged, 6724 Szeged, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yao","family":"Meng","sequence":"additional","affiliation":[{"name":"Faculty of Sports Science, Ningbo University, Ningbo 315211, China"},{"name":"Doctoral School of Safety and Security Sciences, Obuda University, 1034 Budapest, Hungary"},{"name":"Faculty of Engineering, University of Szeged, 6724 Szeged, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B\u00edr\u00f3","family":"Istv\u00e1n","sequence":"additional","affiliation":[{"name":"Doctoral School of Safety and Security Sciences, Obuda University, 1034 Budapest, Hungary"},{"name":"Faculty of Engineering, University of Szeged, 6724 Szeged, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2187-9440","authenticated-orcid":false,"given":"Yaodong","family":"Gu","sequence":"additional","affiliation":[{"name":"Faculty of Sports Science, Ningbo University, Ningbo 315211, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1558","DOI":"10.1080\/00140139.2013.821171","article-title":"A comparison of two physical ability tests for firefighters","volume":"56","author":"Mamen","year":"2013","journal-title":"Ergonomics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"22","DOI":"10.1115\/1.2010-Jul-1","article-title":"Wind, fire and high-rises","volume":"132","author":"Madrzykowski","year":"2010","journal-title":"Mech.
