Summary:(150 lb), the forces exerted on the force plates (p=0.0001)
(p=0.0014)moments at the knee increased. For the longer

a wheel larger than 20.3 cm (8 in) and redesign of the runner
accelerations at the hip (p=0.0442) and L5/S1 (p=0.0145) as
accelerations at the shoulder (p=0.0356) and elbow (p=0.0090)
also increased for the heavier load. For the smaller

and the dynamic moments (P=0.0001) at the shoulder, hip,

at L5/S1 increased. The psychophysical study (n=20)
