Power Poles（TM）是一种专门设计用于行走的橡胶头滑雪杖。Power Poles（TM）模拟了越野滑雪时的手臂运动，从而增加了行走时使用的肌肉量。本研究调查了与使用助行杆相关的运动强度和能量消耗的潜在增加。32名健康的志愿者（16名男性和16名女性），年龄在19岁到33岁之间。每个人在不同的日子完成了跑步机最大耗氧量（VO(2)max）测试和两次随机分配的次最大步行试验（一个带杆，一个不带杆）。每次步行试验都在一个水平的跑步机上进行，以相同的自我选择的速度进行20分钟。每分钟记录一次气体过期、每分钟心跳率（bpm）和感知运动评分（RPE）。使用重复测量方差分析和Tukey事后检验比较试验之间的结果。研究发现，用竿子走路平均会导致23%（4.4毫升）的脑积水。公斤(1)。min(-1))较高的VO2，高22%的热量消耗（1.5千卡）。Min(-1))和16% （18 bpm）的心率反应比在跑步机上不带杆子行走高。使用极的RPE值平均高出1.5个单位，不同条件下男性和女性的反应模式相似。因此，在给定的速度下，使用电线杆可以增加步行的强度，从而可以为步行者提供额外的训练益处。
Power Poles((TM)) are specially constructed, rubber-tipped ski poles designed for use during walking Using Power Poles((TM)) simulates the arm motion of crosscountry skiing, thus increasing the muscle mass used during walking. This study investigated the potential increases in exercise intensity and energy cost associated with the use of walking-poles. Thirty-two apparently healthy volunteers (16 men and 16 women) between the ages of 19 and 33 years participated. Each completed a treadmill maximal oxygen consumption (VO(2)max) test and two randomly assigned, submaximal walking trials (one with poles and one without poles) on separate days. Each walking trial was conducted on a level treadmill, for 20 minutes, at an identical self-selected pace. Expired gases, heart rate in beats per minute (bpm), and ratings of perceived exertion (RPE) were recorded each minute. Results between trials were compared using repeated measures analysis of variance and Tukey's Post hoc tests. It was found that walking with poles resulted in an average of 23% (4.4 ml . kg(-1). min(-1)) higher VO2, 22% higher caloric expenditure (1.5 kcal . min(-1)), and 16% (18 bpm) higher heart rate responses compared to walking without poles on a treadmill. RPE values averaged 1.5 units higher with the use of the poles, and the pattern of responses between conditions was similar for men and women. It is concluded that the use of Power Poles((TM)) can increase the intensity of walking at a given speed and, thus, may provide additional training benefits to walkers.
