Abstract Summary
Professional player feedback and regulations implemented by the National Hockey League (NHL) dictate equipment modifications for ice hockey goaltenders. Recent regulation changes for goaltender chest and arm equipment in the NHL has sparked concern about player safety and performance. The objective of this research was to quantify mobility performance differences as a result of the mandatory rule change. Fourteen participants conducted reach envelope analysis in four equipment conditions, including a condition that met the new equipment standards. There were no statistically significant differences in reach envelope between the equipment conditions, despite the decrease in shoulder and under arm equipment girth.
