To evaluate the arm propulsion force in poling technique of cross-country skiing, a measurement system has been developed. The force was measured using biaxial strain gauges which were fixed at the lower end of the pole. For the data aquisition, a telemetry technique system has been applied. Sizeand weight of the attachment to the body were small enough for the skiing. With this system non-restraint measurement could be performed in an open-air environment, When the elite skier maintained the racing speed in a moderate uphill 'course, he showed greater peak forces in both poles and higher skiing speed than the ordinal skier.Another test with three top-level collegiate competitors revealed that both the poling force of a dominant side and the skiing speed were greater in the performance with abducted shoulder joint position than that with adducted shoulder position.

为了评价越野滑雪撑杆技术中手臂推力的大小，研制了一套测量系统。力的测量使用固定在杆子下端的双轴应变片。在数据采集方面，采用了遥测技术系统。连接在身体上的附件的大小和重量对于滑雪来说都足够小了。利用该系统可以在野外环境中进行无限制测量，当优秀滑雪运动员保持中等上坡速度时，其两极峰值力量和滑雪速度均高于普通滑雪运动员。另一项与3名高水平大学生选手的测试表明，外展肩关节姿势的优势侧撑杆力和滑雪速度均大于外展肩关节姿势的表现。
