Thirty male soccer players (age: 18.10 \u00b1 0.66 years; height: 179 \u00b1 0.06 cm; body mass: 76.22 \u00b1 4.76 kg; systematic practice: 8.6 \u00b1 1.73 years) participated in the study and were randomly assigned to an experimental group (EG; n = 18) or a control group (CG; n = 12). The research was conducted during a training camp. The intervention period lasted 6 weeks and during that period all players performed their usual soccer training. However, the EG performed two weekly sessions of a supplementary training of resisted sprints with a ball. Within-group analysis showed significant improvements in 5-m (<jats:italic>p<\/jats:italic> = 0.005) and 10-m (<jats:italic>p<\/jats:italic> = 0.016) sprint performance; and New multi-change of direction agility test (NMAT; <jats:italic>p<\/jats:italic> = 0.002), Illinois (IAT; <jats:italic>p<\/jats:italic> = 0.002), T-test (<jats:italic>p<\/jats:italic> = 0.003), Arrowhead COD (Arrowhead-R, <jats:italic>p<\/jats:italic> = &lt; 0.001; Arrowhead-L, <jats:italic>p<\/jats:italic> = &lt; 0.001) test and Zigzag agility test (Zigzag-B; <jats:italic>p<\/jats:italic> = 0.006) from pretest to posttest in EG. However, the CG didn\u2019t show any significant improvements. Between-groups analysis revealed differences in favor of the EG in Zigzag-B, IAT, Arrowhead-R, Arrowhead-L and NMAT. This study\u2019s results support the efficacy of a short-term training program that includes resisted sprints exercises to improve the performance of soccer players.<\/jats:p>","DOI":"10.1371\/journal.pone.0311002","type":"journal-article","created":{"date-parts":[[2024,10,2]],"date-time":"2024-10-02T17:30:58Z","timestamp":1727890258000},"page":"e0311002","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":12,"title":["Effects
