The protocol describes guidelines and steps for taking repeated measurements of sportive population: postural stability, body weight distribution during quiet stance, and the foot type diagnostic. The parameters calculated from repeated measurements can be used for separate analyses: analysis of center of pressure displacement, represented by total travelled way parameter; analysis of body weight distribution and loading of the lower limbs; and foot typology. The guidelines are mostly based on recommendations of the literature, partly on our own research experiences. It is important to remain consistent during all of the measurements and follow the guidelines as they control important aspects of the measurements. Any changes of any aspects can signifficantly alter the final results.
