    Developing an instrumented scrum machine to measure strength and stability performance : a thesis presented in partial fulfillment of the requirements for the degree of Master of Engineering in Mechatronics at Massey University, Manawatū, New Zealand
    (Massey University, 2023) Jones, Euan Patrick
    Over the last two decades, there has been plenty of research involving an instrumented scrum machine to understand the forces and biomechanics during the scrum. A lot of the research was aimed at understanding and reducing the risk of injury, which led to significant changes to the scrum and its rules. There was a clear gap in understanding the relationship between the forces in the vertical and horizontal planes of motion during a scrum sustained push. There was also a gap in the research on measuring a player’s ability to control force in the vertical plane of motion to indicate stability. A new, prototype, a single-man scrum machine was developed to examine these gaps in the research and provide new measurements of strength and stability performance. Two experiments were carried out on the new scrum machine to provide enough data from four participants. From the resulting data, the conclusion was made that there is a strong positive linear relationship between the vertical and horizontal forces produced in the scrum. There was also enough evidence to conclude that the new scrum machine could measure a player’s ability to control the vertical force as they pushed. While also completing the aims of this research, the work completed in this project has opened new opportunities for further development around this topic.
