Force plates are a straightforward tool to assess human acceleration as an indicator of human performance. Understanding of the physical principle, and also of the test instruction is required to arrive at meaingful results and interpretations. Notably, performance and physiology levels can differ. A series of studies in healthy people has yielded that peak jumping power is a robust, ecological measure of performance and physiology. It shows a very pronounced decline with age. Morover, these studies reveal that sports is beneficial for muscles and bones. Some benefits by sports diminish with age (bone, muscle), but fracture reduction by sports extends into 10th decade of life.
