Magnitudes and directions of AVER75 and HIGH100 peak forces and moments and the conversion factor fAH.

Average = average of peak force Fres from all subjects. Range = range from 10 single subjects. Range [%] = Range in percent of average. αfront, αsagit and αtrans = angles of the peak force vector in frontal, sagittal and transverse planes (see Fig 1). These angles are the same for AVER75 and HIGH100 loads. fAH = factor for calculation of AVER75 from HIGH100 loads for all 6 load components and their resultants: AVER75 = HIGH100 / fAH. a/b = highest/lowest absolute values except from cycling and jogging. * = Mres is low at the first peak of Fres.
