This study analyzed the jumps of over 2,000 athletes to determine the predictive nature of kinematic and kinetic variables related to jump height. Ten variables were reviewed with varying predictive attributes.
Research Topic: Performance
Evaluating Movement Strategies of the Countermovement Jump in Marine Officer Candidates
This study found that specific key indicators in DARI Motion data helped lead to the prediction of musculoskeletal (MSK) issues in marines. These tools could add value in creating modifiable strength and conditioning training programs before or during military training.
Post ACL Reconstruction: Evidence-Based Data Models for Return-to-Play Criteria
This study demonstrated the clinical utility of DARI Motion as a tool that can track the progression of a post-surgical knee injury. The findings illustrate that the return-to-play criteria is useful in a surgeon’s decision-making process.
Analyzing In Vivo Hip Kinematics in Elite Baseball Batters with Markerless Motion Capture
This study demonstrates the clinical utility of the kinematics produced by DARI Motion and how they can be applied to better understand athletic movement. DARI captured the active hip range of motion during the batting swings of 29 elite-level baseball players.
Baseball Pitching Kinematics: Marker-Based Vs. Markerless Motion Capture
This kinematics validation study compared DARI to a motion analysis corporation (MAC) system for measurements assessing pitching performance. The multi-joint evaluation showed the coefficient of multiple correlations for eight data signals was between .90-.99.
Deriving Accurate Ground Reaction Forces With a Motion Capture System vs. a Force Plate
This kinetic validation study compared DARI Motion’s patented ground reaction force model to a direct measure of a force plate. Based on three body weight squats for five healthy men, the results showed excellent agreement with a r<sup>2</sup> = .989 and SEM = 11 Newtons.
Basketball Dunk Kinetics: Validating the Accuracy of a 3D Markerless Motion Capture System
This kinetic validation study compared jumping tasks using DARI Motion’s patented ground reaction force model to the direct measure of a force plate. The findings indicate the DARI Motion model can accurately assess peak force and peak power during jumping.
Capturing Lower Extremity Kinematics & Jump Characteristics in Young Children with DARI
This study involved the concurrent measurement of kinematic motion for 14 preschool children with a marker-based and markerless motion capture system. It demonstrates the ability of DARI to track children’s kinematic motion within an acceptable level of agreement and reliability.
Active Range of Motion of the Shoulder: A Cross-Sectional Study of 6,635 Subjects
This study took a subset of the DARI Motion database for active shoulder range of motion (ROM) and established normative values across age, gender, and arm. The results provide an accurate normative reference for the general population.
