Analyzing Drop Jump Ground Reaction Forces in Microsoft Excel

Analysis of ground reaction forces during a drop jump can provide greater insight into stretch-shortening cycle function and jump-landing strategy than performance metrics such as jump height, ground contact time, and reactive strength index. Commercially available force plates have customized processing software capable of calculating many variables, but this software can be cost-prohibitive for many academics and practitioners. Using the accompanying spreadsheet outlined in this article, any professional can quickly process force plate data and enhance their assessment of an athlete's stretch-shortening cycle function and plyometric performance to guide future training objectives.
