Assessment of physical fitness during pregnancy: validity and reliability of fitness tests, and relationship with maternal and neonatal health - a systematic review. BMJ Open Sport Exerc Med. 2022 Sep 23;8(3):e0013182055-7647http://hdl.handle.net/10668/20151To systematically review studies evaluating one or more components of physical fitness (PF) in pregnant women, to answer two research questions: (1) What tests have been employed to assess PF in pregnant women? and (2) What is the validity and reliability of these tests and their relationship with maternal and neonatal health? A systematic review. PubMed and Web of Science. Original English or Spanish full-text articles in a group of healthy pregnant women which at least one component of PF was assessed (field based or laboratory tests). A total of 149 articles containing a sum of 191 fitness tests were included. Among the 191 fitness tests, 99 (ie, 52%) assessed cardiorespiratory fitness through 75 different protocols, 28 (15%) assessed muscular fitness through 16 different protocols, 14 (7%) assessed flexibility through 13 different protocols, 45 (24%) assessed balance through 40 different protocols, 2 assessed speed with the same protocol and 3 were multidimensional tests using one protocol. A total of 19 articles with 23 tests (13%) assessed either validity (n=4), reliability (n=6) or the relationship of PF with maternal and neonatal health (n=16). Physical fitness has been assessed through a wide variety of protocols, mostly lacking validity and reliability data, and no consensus exists on the most suitable fitness tests to be performed during pregnancy.enAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/Fitness testingGestationPhysical activityPregnancy outcomesWomenInfant, newbornFemalePregnancyCardiorespiratory fitnessPregnant womenReproducibility of resultsInfant healthPhysical fitnessSystematic reviews as topicresearch article36172399open accessAptitud físicaCapacidad cardiovascularEmbarazoFemeninoMujeres embarazadasRecién nacidoReproducibilidad de los resultadosRevisiones sistemáticas como asuntoSalud del lactante10.1136/bmjsem-2022-001318PMC9511659https://bmjopensem.bmj.com/content/bmjosem/8/3/e001318.full.pdfhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC9511659/pdf
