    Sport Biomechanics and Performance

    In competitive sports coaches and athletes are looking to obtain a competitive edge over their opponents. Sport biomechanics is becoming a popular choice to increase performance by identifying mechanical flaws and aiding in injury prevention. Sport movement analysis provided by the Biomechanics Lab at East Carolina University offers two analysis packages:  Movement Analysis and Three Dimensional Motion Analysis.

    Movement Analysis

    Utilizing Dartfish software, Movement Analysis determines the details of a sport skill recorded by a digital video camera during practice or in a game situation.

    Dartfish Movement Analysis is a cost- and time-effective alternative to laboratory motion analysis and can be performed for an individual athlete or an entire team.

    Using a standard or high speed video camera in combination with advanced software, Movement Analysis service can be performed in any location and is available for any athletic event.

    Movement Geometry

    This analysis allows coaches to identify a potential location and time for error to occur and obtain quantifiable data to track progressions of athletes’ improvement by providing a freeze-frame description of the critical phases of a skill and numerically annotates the position of anatomical structures.

    Distance and Velocity

    Using a high speed camera we have the capability to record any high speed motion (such as pitching) and calculate distances and linear velocities which are impossible with a standard definition camera.


    A Trajectory Analysis depicts in serial pictures the trajectory of an anatomical structure, object, or implement. By tracking the trajectory of an object or body segment coaches and players will obtain visual information of flight path. This baseball example contrasts flight path from a catcher’s perspective between pitches.

    Three Dimensional Motion Analysis (Laboratory Session)

    Preparation for this analysis involves the placement of reflective markers on anatomical landmarks, allowing software to re-create a 3D representation of an athlete’s movements.  3D Motion Analysis is the most sophisticated and accurate technique currently available to analyze human movement and it incorporates technology used in biomechanics research, video games, and animation. 

    3D Motion Analysis provides highly detailed pictorial and numerical insights into the mechanics of an athletic movement, the coordination between body parts, and the kinetic chain, and can often be combined with the analyses of forces applied to the ground, creating an analytical output that is not possible to achieve in the field.

    3D Motion Analysis has the potential to identify variables that lead to an improved performance and decrease risks for injury. It can be used to compare different athletes as well as to document progress over time using repeated tests.  Currently, this service is most suitable for baseball players and golfers.
