However, the effect of low doses of Cr on the physical performance of young soccer players is unknown. This study determined the effect of a low dose of orally administered Cr on muscle power after acute intra-session fatigue in young soccer players. Twenty-eight young soccer players (mean age = 17.1 \u00b1 0.9 years) were randomly assigned to either a Cr (n = 14, 0.3 g\u00b7kg\u22121\u00b7day\u22121 for 14 days) or placebo group (n = 14), using a two-group matched, double-blind, placebo-controlled design. Before and after supplementation, participants performed 21 repetitions of 30 m (fatigue induction), and then, to measure muscle power, they performed four repetitions in half back squat (HBS) at 65% of 1RM. Statistical analysis included a two-factor ANOVA (p \u02c2 0.05). Bar velocity at HBS, time: p = 0.0006, \u014bp2 = 0.22; group: p = 0.0431, \u014bp2 = 0.12, time \u00d7 group p = 0.0744, \u014bp2 = 0.02. Power at HBS, time: p = 0.0006, \u014bp2 = 0.12; group: p = 0.16, \u014bp2 = 0.06, time \u00d7 group: p = 0.17, \u014bp2 = 0.009. At the end of the study, it was found that, after the induction of acute intra-session fatigue, a low dose of Cr administered orally increases muscle power in young soccer players.<\/jats:p>","DOI":"10.3390\/nu16091324","type":"journal-article","created":{"date-parts":[[2024,4,29]],"date-time":"2024-04-29T04:26:16Z","timestamp":1714364776000},"page":"1324","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Effects
