Abstract

The purpose of this study was to examine the effect of applying Qualitative Movement Diagnosis (QMD) on sprint start performance. Twelve NCAA II sprinters volunteered for this cross-sectional study. The steps of applying QMD in sprint start performance were introduced. Subjects were asked to perform three pre-intervention trials of block starts in their preferred setting. The block setting and joint kinematics at knee and hip from both sides of body were evaluated. The feedback was provided for the three post-intervention trials. A moderate effect of significant improvement of exist velocity (p = 0.04) was observed as well as lead leg hip angle (p = 0.004), rear leg knee angle (p = 0.001), and block spacing (p < 0.001). QMD, which consists of preparation, observation, evaluation/diagnosis, and intervention, can be used to effectively change and improve sprint start performance.
