Thirty-one women (33.1 \u00b1 7.3 y) were randomly assigned into a supplement (ACC, n = 14) or a placebo (PL, n = 17) group. On day 1 and following 9 weeks of intervention, the participants underwent anthropometric measurements and filled out a food frequency questionnaire (FFQ) and sports injuries questionnaires. 1-RM values were measured for the back squat and bench press exercises. All the participants significantly (p = 0.01) improved their mean back squat and bench press 1-RM values (time effect). While no between-group difference was observed in the bench press 1-RM values, the ACC groups\u2019 mean post-pre bench press 1-RM differences (\u03941-RM) were significantly higher than in the PL group, expressed in kg (p = 0.049), per body mass (p = 0.042), or per lean body mass (p = 0.035). No significant interaction was observed for time X group effect (p = 0.421). No differences (within- or between-groups) were observed in the anthropometric values or in the questionnaires\u2019 results. ACC supplementation revealed an ergogenic effect by augmenting the improvement of maximum amount generated force, which can possibly be attributed to the calcium and\/or the carbonate components.<\/jats:p>","DOI":"10.3390\/nu15030538","type":"journal-article","created":{"date-parts":[[2023,1,20]],"date-time":"2023-01-20T02:43:29Z","timestamp":1674182609000},"page":"538","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The Effects of Amorphous Calcium Carbonate (ACC) Supplementation on Resistance Exercise Performance in Women"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6987-6209","authenticated-orcid":false,"given":"Yitzhak","family":"Weinstein","sequence":"first","affiliation":[{"name":"Department of Nutritional Sciences, Tel-Hai Academic College, Kiryat Shmone 1220800, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6465-2268","authenticated-orcid":false,"given":"Yarden","family":"Ovadia","sequence":"additional","affiliation":[{"name":"Department of Nutritional Sciences, Tel-Hai Academic College, Kiryat Shmone 1220800, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bar","family":"Weinstein","sequence":"additional","affiliation":[{"name":"Department of Statistics and Operations Research, Tel Aviv University, Tel Aviv 6997801, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ayelet","family":"Weinstein","sequence":"additional","affiliation":[{"name":"Department of Nutritional Sciences, Tel-Hai Academic College, Kiryat Shmone 1220800, Israel"},{"name":"Department of Sports Medicine and Research, Wingate Institute, Netanya 4290200, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1780","DOI":"10.1093\/ajcn\/86.5.1780","article-title":"Calcium intake and hip fracture risk in men and women: A meta-analysis of prospective cohort studies and randomized controlled trials","volume":"86","author":"Baron","year":"2007","journal-title":"Am.
