The aim of the present scoping review was to present the image-based analysis methods that have being utilized to assist Track and Field coaches to observe the technique of their athletes aiming towards the optimization of performance. From the era of early photography till the current innovation of markerless motion analysis, sports and track and field athletes in particular are the field where the technological advances in image capturing and analysis are implemented for both practical, as well as for scientific purposes. The outcome of the blending of technology and sports science is the better understanding of human motion, the exploitation of its movement abilities, and its ideal segmentation when teaching sport techniques that has led to the optimization of sport performance and the identification of the unique prospects of human performance as presented by elite athletes. The chapter is comprised by a short description of the evolution in motion analysis methods, its contribution in the understanding sport techniques, its exploitation to create tools to effectively teach sport technique, and the presentation of the technological innovations that will assist track and field coaches in the future.
