Jeopardizing Christmas: Why spoiled kids and a tight schedule could make Santa Claus fall?

Abstract

Santa Claus' spatio-temporal gait characteristics, ground reaction forces during treadmill walking as well as postural sway during loaded, unloaded and cognitive interference tasks were examined in order to estimate his fall risk.Seventeen healthy males, disguised as researchers and students (age: 30±10 years; height: 179±6 years; weight: 76±7kg; BMI: 24±2kg/m2; physical activity: 12±4h/week) and who still believe in Santa Claus randomly underwent balance and gait analyses with and without cognitive interference. The conditions were to be dressed as "Santa Claus" (wearing costume consisting of a beard, cap, robe, heavy sack with a load of 20kg) or dressed in "normal clothing" (no costume). Spatiotemporal gait parameters (walking velocity, gait variability and stride time, length and width), ground reaction forces (GRF) (left- and right-sided heel strike and push off) and postural sway (30s tandem stance on a force plate) were measured."Santa-effects" (0.001.
