SQUAT DEPTH IMPACTS ON JOINT SPECIFIC VERTICAL JUMP

Abstract

BACKGROUND: Previous studies have investigated the impact of squat depth in training on vertical jump, but study into the use of specific joint angles is still needed. Explosive sports such as basketball and football often require athletes to jump out of shallow joint angles. Understanding training within these shallow joint angles is critical to enhancing athletic performance. The purpose of the proposed study is to see how training squats from different depths impacts vertical jump height and maximal isometric force from different joint angles. METHODS: 40 resistance trained athletes will complete a nine week training program. They will be randomly assigned to one of four groups. Each group will consist of their regular training with either full squats, half squats, or quarter squats added in addition. The fourth group will complete a progression consisting of three weeks of full squats, three weeks of half squats, then three weeks of quarter squats. All squats will be front squats. At baseline, vertical jump from specific joint angles via jump mat and maximal isometric force from different joint angles via biodex will be measured. After the nine week training protocol, the tests done at baseline will be repeated to test for changes. A repeated measures ANOVA will be used to detect significant effects of the training. ANTICIPATED RESULTS: It is expected that the group that progresses through each squat type will induce the greatest increases in vertical jump height and maximal isometric force, particularly at shallow joint angles. It is hypothesized that deep squats create greater gains in general strength, which translates to strength in more specific joint angles, such as quarter squats.
