Fourteen participants (age: 24.9 \u00b1 2.4 years) wore a chest strap HR monitor and placed three accelerometers at the left wrist (non-dominant), trunk, and right shank, respectively. The %HRR and two different AIMs (Player Load per minute [PL\/min] and mean amplitude deviation [MAD]) during exercise were calculated. During running, both AIMs at the shank and PL at the wrist had strong correlations (r = 0.777\u20130.778) with %HRR; while other combinations were negligible to moderate (r = 0.065\u20130.451). For basketball, both AIMs at the shank had stronger correlations (r = 0.604\u20130.628) with %HRR than at wrist (r = 0.536\u20130.603) and trunk (r = 0.403\u20130.463) with %HRR. During badminton exercise, both AIMs at shank had stronger correlations (r = 0.782\u20130.793) with %HRR than those at wrist (r = 0.587\u20130.621) and MAD at trunk (r = 0.608) and trunk (r = 0.314). Wearing the sensor on the shank is an ideal position for both AIMs to monitor external intensity in running, basketball, and badminton, while the wrist and using PL-derived AIM seems to be the second ideal combination.<\/jats:p>","DOI":"10.3390\/s22072583","type":"journal-article","created":{"date-parts":[[2022,3,29]],"date-time":"2022-03-29T21:45:51Z","timestamp":1648590351000},"page":"2583","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Ideal Combinations of Acceleration-Based Intensity Metrics and Sensor Positions to Monitor Exercise Intensity under Different Types of Sports"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4742-587X","authenticated-orcid":false,"given":"Wei-Han","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Athletic Performance, National Taiwan Normal University, Taipei City 106, Taiwan"},{"name":"Graduate Institute of Sports Equipment Technology, University of Taipei, Taipei City 111036, Taiwan"}]},{"given":"Chun-Wei","family":"Chiang","sequence":"additional","affiliation":[{"name":"Department of Athletic Performance, National Taiwan Normal University, Taipei City 106, Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1744-7020","authenticated-orcid":false,"given":"Nicholas J.","family":"Fiolo","sequence":"additional","affiliation":[{"name":"Department of Athletic Performance, National Taiwan Normal University, Taipei City 106, Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7463-8301","authenticated-orcid":false,"given":"Philip X.","family":"Fuchs","sequence":"additional","affiliation":[{"name":"Department of Athletic Performance, National Taiwan Normal University, Taipei City 106, Taiwan"},{"name":"Department of Sport and Exercise Science, University of Salzburg, 5400 Salzburg, Austria"}]},{"given":"Tzyy-Yuang","family":"Shiang","sequence":"additional","affiliation":[{"name":"Department of Athletic Performance, National Taiwan Normal University, Taipei City 106, Taiwan"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"10","DOI":"10.1249\/FIT.0000000000000438","article-title":"Worldwide survey of fitness trends for 2019","volume":"22","author":"Thompson","year":"2018","journal-title":"ACSMs Health Fit.
