A distinguishing feature of elite cross-country skiers is their superlative upper-body power (UBP). Recently, roller board training was shown to be superior for improving UBP in cross-country skiers; however, the newly developed wind machine had not yet been tested. The purpose of this study was to determine if wind machine training was as effective as roller board training at increasing UBP. Forty-four women cross-country skiers, age 23-59 years, were matched on initial UBP, measured in watts (W), and placed into 1 of 2 experimental groups (roller board or wind machine). All women underwent 8 weeks of UBP training. Although both groups improved significantly pre-post (p < 0.05) in UBP, t-tests indicated that there was no significant difference (p > 0.05) between the 2 groups' improvements (roller board, pre 74.5 +/- 30.9, post 95.9 +/- 29.8 W; wind machine, pre 74.5 +/- 33.5, post 99.3 +/- 34.3 W). Thus the wind machine was as effective at enhancing UBP as the roller board.
精英越野滑雪运动员的一个显著特征是他们具有极高的上身力量（UBP）。最近，研究表明，轮滑板训练对提高越野滑雪运动员的上身力量更有优势；然而，新开发的风力训练机尚未经过测试。本研究的目的是确定风力训练机训练在增加上身力量方面是否与轮滑板训练同样有效。44名年龄在23至59岁之间的女子越野滑雪运动员，根据以瓦特（W）为单位测量的初始上身力量进行匹配，并分为2个实验组之一（轮滑板组或风力训练机组）。所有女性都接受了为期8周的上身力量训练。尽管两组在训练前后的上身力量均有显著提高（p < 0.05），但t检验表明，两组之间的提高没有显著差异（p > 0.05）（轮滑板组，训练前74.5 +/- 30.9，训练后95.9 +/- 29.8 W；风力训练机组，训练前74.5 +/- 33.5，训练后99.3 +/- 34.3 W）。因此，风力训练机在增强上身力量方面与轮滑板同样有效。
