In this study, 26 professional soccer players participated in strength training (ST) twice a week and were tested with IRT consistently across the 1-year. Strength, vertical jump, heat differences and injuries were tracked and analyzed. Results: 69 injuries occurred during 12 months of tracking; most identified injuries were: contusions, sprains, strains to the thigh (n = 16), ankle (n = 15) and knee (n = 12). Differences (&gt;7 \u00b0C) in IRT patterns were noted among injured and non-injured athletes. Significant improvements in strength (p &lt; 0.005) were found for vertical jump, bench press, front lat pull down, shoulder press, leg press, leg curl and squat. Number of injuries decreased from 23 (33.3%) to 14 (20.3%) when early year rates were compared to late year (p &lt; 0.005). Combined ST and IRT represent useful strategies for reducing injuries among U-20 soccer players.<\/jats:p>","DOI":"10.3390\/sports6040148","type":"journal-article","created":{"date-parts":[[2018,11,22]],"date-time":"2018-11-22T09:18:25Z","timestamp":1542878305000},"page":"148","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Effects of Strength Training Program and Infrared Thermography in Soccer Athletes Injuries"],"prefix":"10.3390","volume":"6","author":[{"given":"Pedro","family":"Menezes","sequence":"first","affiliation":[{"name":"Escola de Educa\u00e7\u00e3o F\u00edsica e Desportes (Departamento de Gin\u00e1stica), Universidade Federal do Rio de Janeiro, Av.
