Abstract：
To investigate the effects of 8-week hiking bench training on cardiorespiratory and muscular responses of highly trained sailors during hiking emulation. Twenty-four sailors were assigned into two groups: the hiking bench training group (HTG, n = 12) and the control group (CG, n = 12). Both groups maintained their regular training with the HTG performed two additional hiking bench training sessions per week for 8 weeks, while the CG performed an equivalent duration of on-water sailing training. Physiological responses were assessed by performing four successive 3-min hiking bouts on a sailing emulation ergometer before and after the 8-week training period. Comparing the pretest, both groups exhibited a significant decrease (p < 0.05) in the percentage of maximal oxygen uptake (%VO2max) and maximal heart rate (%HRmax); the HTG experienced a greater decrease in %VO2max in bouts 2 and 3. The root mean square (RMS) of rectus femoris (RF), vastus lateralis (VL), rectus abdominis (RA), and external oblique decreased significantly (p < 0.05), whereas the mean power frequency (MPF) of RF, VL, and RA exhibited an increasing trend. The RMS of RF and RA in HTG were lower than those in CG in the initial three bouts; VL and EA in HTG were lower than those in CG in bouts 1 and 2 (p < 0.05). The MPF of RA in HTG was significantly increased in bouts 2, 3, and 4 (p < 0.05). Eight-week hiking bench training could improve hiking economy and the activation of lower limb and trunk muscles delaying the onset of fatigue in sailors.
摘要：
目的研究8周远足长凳训练对远足模拟中训练有素的水手心肺和肌肉反应的影响。二十四名水手被分成两组:远足长凳训练组(HTG,n=12)和对照组(CG，n=12)。两组均保持常规训练，HTG每周进行两次额外的远足长凳训练，为期8周，而CG进行了相同的水上航行训练。在8周的训练期之前和之后，通过在帆船仿真测功机上连续进行四次3分钟的徒步旅行来评估生理反应。比较预测试，两组的最大摄氧量百分比(%VO2max)和最大心率(%HRmax)均显著下降(p<0.05);HTG在第2次和第3次发作中%VO2max下降幅度更大.股直肌（RF）的均方根（RMS），股外侧肌（VL），腹直肌（RA），外斜线明显下降（p<0.05），而射频的平均功率频率(MPF)，VL,RA呈增加趋势。在最初的三个回合中，HTG中RF和RA的RMS低于CG。在第1和第2回合中，HTG中的VL和EA低于CG中的VL和EA（p<0.05）。在第2、3和4次发作中，HTG中RA的MPF显着增加（p<0.05）。为期八周的徒步旅行长凳训练可以提高徒步旅行的经济性，并激活下肢和躯干肌肉，从而延缓水手疲劳的发作。
