When tracking devices are unavailable or impractical to use, perceived velocity loss (PVL) can be used as a substitute, assuming sufficient accuracy. Here, we investigated the accuracy of PVL equal to 20% and 40% relative to the first repetition in the bench-press exercise. <jats:italic><jats:bold>Methods<\/jats:bold>:<\/jats:italic> Following a familiarization session, 26 resistance-trained men performed 4 sets of the bench-press exercise using 4 different loads based on their individual load\u2013velocity relationships (\u223c40%\u201390% of 1-repetition maximum [1RM]), completed in a randomized order. Participants verbally reported their PVL at 20% and 40% velocity loss during the sets. PVL accuracy was calculated as the absolute difference between the timing of reporting PVL and the actual repetition number corresponding to 20% and 40% velocity loss measured with a linear encoder. <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> Linear mixed-effects model analysis revealed 4 main findings. First, across all conditions, the absolute average PVL error was 1 repetition. Second, the PVL accuracy was not significantly different between the PVL thresholds (<jats:italic>\u03b2<\/jats:italic>\u2009=\u20090.16, <jats:italic>P<\/jats:italic>\u2009=\u2009.267). Third, greater accuracy was observed in loads corresponding to the midportion of the individual load\u2013velocity relationships (\u223c50%\u201360% 1RM) compared with lighter (&lt;50% 1RM, <jats:italic>\u03b2<\/jats:italic>\u2009=\u20090.89, <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001) and heavier loads (&gt;60% 1RM, 0.63\u2009\u2264\u2009<jats:italic>\u03b2<\/jats:italic>\u2009\u2264\u20090.84, all <jats:italic>P<\/jats:italic> values\u2009&lt;\u2009.001). Fourth, PVL accuracy decreased with consecutive repetitions (<jats:italic>\u03b2<\/jats:italic>\u2009=\u20090.05, <jats:italic>P<\/jats:italic>\u2009=\u2009.017). <jats:italic><jats:bold>Conclusions<\/jats:bold>:<\/jats:italic> PVL can be implemented as a monitoring and prescription method when velocity-tracking devices are impractical or absent.<\/jats:p>","DOI":"10.1123\/ijspp.2022-0298","type":"journal-article","created":{"date-parts":[[2023,3,16]],"date-time":"2023-03-16T13:21:06Z","timestamp":1678972866000},"page":"488-494","source":"Crossref","is-referenced-by-count":10,"title":["Perception of Bar Velocity Loss in Resistance Exercises: Accuracy Across Loads and Velocity Loss Thresholds in the Bench Press"],"prefix":"10.1123","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0204-0957","authenticated-orcid":true,"given":"Antonio","family":"Dello Iacono","sequence":"first","affiliation":[{"name":"School of Health and Life Sciences, Institute for Clinical Exercise and Health Science, University of the West of Scotland, Hamilton, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin","family":"Watson","sequence":"additional","affiliation":[{"name":"School of Health and Life Sciences, Institute for Clinical Exercise and Health Science, University of the West of Scotland, Hamilton, United Kingdom"},{"name":"Strength and Conditioning Department, Glasgow School of Sport, Glasgow, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Milan","family":"Marinkovic","sequence":"additional","affiliation":[{"name":"School of Health and Life Sciences, Institute for Clinical Exercise and Health Science, University of the West of Scotland, Hamilton, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2254-2698","authenticated-orcid":true,"given":"Israel","family":"Halperin","sequence":"additional","affiliation":[{"name":"School of Public Health, Tel Aviv University, Tel Aviv, Israel"},{"name":"Sylvan Adams Sports Institute, Tel Aviv University, Tel Aviv, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"4","key":"r1","series-title":"Strength Cond J","first-page":"34","article-title":"Autoregulated resistance training: does velocity-based training represent the future?","volume":"41","author":"Nevin J","year":"2019","unstructured":"Nevin J.
