To gain knowledge of the loading on the musculoskeletal system during various movements it is essential to
collect biomechanical data. This provides information on the forces that act on specific parts of the body and can
give insight on possible risk factors for injuries or how to improve performance.
One of the key problems when collecting biomechanical data is that tests performed in a laboratory environment
are limited to the available space. Therefore performed movements are bound to several restrictions, which can
make it difficult to perform the movements naturally. Consequently it is questionable how valid the outcomes will
be for actual in-game scenarios.
On the other hand, field tests are also limited by several factors. Not all equipment is suitable for use outdoors or
difficult to incorporate in a realistic environment, for example a grass soccer pitch. Pressure insoles could provide a
practical outcome for collecting data on the experienced vertical ground reaction forces (vGRF). Since the insoles
are put in the shoe they can be used in the laboratory or field. An other advantage is that the data collection unit is
small, which means that it has easy transportability. However, while some previous studies have used these insoles
