This study explored the responses of heart rate (HR), muscle oxygen saturation (SmO2), and perceived exertion (RPE) during six body-weight squat exercise variations. A total of 15 recreationally active participants (age: 28.2 \u00b1 8.0 years; body mass: 71.1 \u00b1 11.2 kg; height: 1.73 \u00b1 0.08 m) were recruited. Six body-weight squat variations (deep, jumping, single-leg, uneven, unstable, and wall-sit) were randomly performed for 90 s. Results revealed that the jumping squat promoted a higher average and peak HR (165.3 \u00b1 14.5 and 146.1 \u00b1 14.8 bpm, respectively), and a lower average SmO2 and higher deoxygenation SmO2 in the soleus muscle (40.3 \u00b1 15.4 and 46.0 \u00b1 11.4%, accordingly). No differences were observed in recovery time or in the same SmO2 derived-parameters in the vastus lateralis muscle. The jumping variation promoted a greater response at a physiological level, both centrally, related to cardiovascular response, and peripherally, related to soleus SmO2. It was also the more demanding variation at both the overall and lower limb muscular level of RPE. This holistic view allows a precise identification of the response patterns in body-weight squat exercise variations to an acute session, with a training intervention providing additional information.<\/jats:p>","DOI":"10.3390\/s25072018","type":"journal-article","created":{"date-parts":[[2025,3,24]],"date-time":"2025-03-24T06:21:38Z","timestamp":1742797298000},"page":"2018","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Acute Physiological and Perceptual Responses to Six Body-Weight Squat Exercise Variations"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5360-9643","authenticated-orcid":false,"given":"Daniel","family":"Santar\u00e9m","sequence":"first","affiliation":[{"name":"Research Center in Sports Sciences, Health Sciences and Human Development, CIDESD, 5000-801 Vila Real, Portugal"},{"name":"Department of Sports Science, Exercise and Health, School of Life Sciences and Environment, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"}]},{"given":"Andreia","family":"Teixeira","sequence":"additional","affiliation":[{"name":"Department of Sports Science, Exercise and Health, School of Life Sciences and Environment, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"}]},{"given":"Ant\u00f3nio","family":"Amaral","sequence":"additional","affiliation":[{"name":"Department of Sports Science, Exercise and Health, School of Life Sciences and Environment, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2335-9991","authenticated-orcid":false,"given":"Jaime","family":"Sampaio","sequence":"additional","affiliation":[{"name":"Research Center in Sports Sciences, Health Sciences and Human Development, CIDESD, 5000-801 Vila Real, Portugal"},{"name":"Department of Sports Science, Exercise and Health, School of Life Sciences and Environment, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"}]},{"given":"Catarina","family":"Abrantes","sequence":"additional","affiliation":[{"name":"Research Center in Sports Sciences, Health Sciences and Human Development, CIDESD, 5000-801 Vila Real, Portugal"},{"name":"Department of Sports Science, Exercise and Health, School of Life Sciences and Environment, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1030","DOI":"10.1136\/bjsports-2016-096581","article-title":"How much is too much?
