A new method for measuring treadmill belt velocity fluctuations: effects of treadmill type, body mass and locomotion speed

Abstract Treadmills are essential to the study of human and animal locomotion as well as for applied diagnostics in both sports and medicine. The quantification of relevant biomechanical and physiological variables requires a precise regulation of treadmill belt velocity (TBV). Here, we present a no...

Using the novel method, we show that TBV regulation differs between treadmill types, and that certain features of TBV regulation are affected by the subjects’ body mass and their locomotion speed.

Average belt speeds varied between about 98 and 103% of the target speed.
