The vertical reaction force component affects motion up and down only and does nothing to propel the skier forward. The relative proportions of the horizontal and vertical reaction forces depend on the angle of the resultant reaction force with respect to horizontal or vertical. In Fig. 2 this depends on the pole angle and how inclined it is from vertical. As the pole inclines away from vertical, the horizontal component, the propulsive force, becomes larger while the vertical CCSC02 26/07/2002 34 12:00 PM Page 34 CHAPTER 2 20º angle Resultant poling force Vertical poling force 200 N 188 N 70º angle 68 N propulsive force Fig.
Newton’s laws tell us that the total force in each of the three-dimensional directions will determine the skier’s acceleration in that direction. • Performance is determined by forward motion, hence those components of reaction force in the forward Performance in cross country skiing is determined by the complex interaction of physiology and mechanics. The forces which drive a skier’s motion come with metabolic expenses and limitations which affect the ability to generate and sustain force at ideal levels.
