This study aimed to examine if a specific 6-week multimodal intervention, combining lumbopelvic control and unning technique exercises, induced changes in pelvis and lower-limb kinematics at maximal speed and improved sprint performance. <jats:italic><jats:bold>Methods<\/jats:bold>:<\/jats:italic> Healthy amateur athletes were assigned to a control or intervention group (IG). A sprint test with 3-dimensional kinematic measurements was performed before (PRE) and after (POST) 6 weeks of training. The IG program included 3 weekly sessions integrating coaching, strength and conditioning, and physical therapy approaches (eg,\u00a0manual therapy, mobility, lumbopelvic control, strength and sprint \u201cfront-side mechanics\u201d-oriented drills). <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> Analyses of variance showed no between-group differences at PRE. At POST, intragroup analyses showed PRE\u2013POST differences for the pelvic (sagittal and frontal planes) and thigh kinematics and improved sprint performance (split times) for the IG only. Specifically, IG showed (1)\u00a0a lower anterior pelvic tilt during the late swing phase, (2)\u00a0greater pelvic obliquity on the free-leg side during the early swing phase, (3)\u00a0higher vertical position of the front-leg knee, (4)\u00a0an increase in thigh angular velocity and thigh retraction velocity, (5)\u00a0lower between-knees distance at initial contact, and (6)\u00a0a shorter ground contact duration. The intergroup analysis revealed disparate effects (possibly to very likely) in the most relevant variables investigated. <jats:italic><jats:bold>Conclusion<\/jats:bold>:<\/jats:italic> The 6-week multimodal training program induced clear pelvic and lower-limb kinematic changes during maximal speed sprinting. These alterations may collectively be associated with reduced risk of muscle strain and were concomitant with significant sprint performance improvement.<\/jats:p>","DOI":"10.1123\/ijspp.2021-0107","type":"journal-article","created":{"date-parts":[[2021,11,18]],"date-time":"2021-11-18T15:42:39Z","timestamp":1637250159000},"page":"374-383","source":"Crossref","is-referenced-by-count":61,"title":["Can We Modify Maximal Speed Running Posture?
