Strength & Conditioning
The purpose of this study was to identify the effect of bar position on the ankle, knee, and hip peak net joint moments (NJM) and associated joint angles during isometric mid-thigh pulls (IMTP). Seven female college lacrosse players performed maximal IMTP at three different bar positions (low: above patella, mid: mid-thigh, high: crease of hip) while motion capture and GRF data were recorded. Inverse dynamics was used to calculate peak ankle, knee, and hip NJM. Joint angles at peak NJM were also extracted. Main effects for bar position existed for hip NJM and hip and knee joint angles. Pair-wise comparisons showed that hip NJM differed significantly between all positions. Strength and sports coaches should consider these results when they use the IMTP to assess and monitor maximal strength as part of their conditioning programs.
