简要总结
The back squat is a commonly utilized resistance training exercise for the promotion of both performance and musculoskeletal health. There are a range of manipulations that can be made to the setup of this resistance exercise, with once such adaptation being the stance width when performing the exercise. This intervention aims to explore the effects of increasing the stance with on performance indices in elite rugby league players.

研究组 & 干预措施
Normal stance width
Those assigned to this group will complete their pre-season training as normal i.e. when performing their squat exercises they will do so using their habitual (self-selected) stance width.
干预措施: Normal stance width (Behavioral)
Wide stance width
Those assigned to this (i.e. experimental) group will also complete their pre-season training as normal, the only exception will be that when performing their squat exercises they will increase their stance width by 20% compared to their self-selected stance width.
干预措施: Wide stance width (Behavioral)
