Understanding force generating capabilities of athletes is an important facet of strength diagnostics. The utilisation of isometric tasks such as the isometric squat and isometric mid-thigh pull are therefore popular methods used to gain a deeper understanding of as to what strength characteristics have changed over a given period. This article aims to provide information on how to understand and analyse the force time curve of isometric tasks in Microsoft Excel, thus providing practitioners an inexpensive and accessible alternative to readily available software on the market.
