【摘要】 运用自研的脉搏声谱检测仪,对不同项目和不同水平的运动员在训练前的脉搏声进行了测试。结果发现:正常安静时的脉搏声时域谱图的波峰都是单峰,且曲线平滑;当运动员前一天的疲劳没有恢复或出现其它情况时,其安静时脉搏声波峰为多峰且有拐点出现;不同水平的运动员在同样负荷后,其安静时脉搏声谱图的能量面积存在着较大差异。更多还原

【Abstract】 Pulse sound monitor developed by the authors was applied in testing pulse sounds of athletes of different events and levels before training. It was shown that the wave peaks of pulse sounds of athletes in silence were single and the curves were smooth. However,if the athletes had not recovered from the (training),the wave peaks were uneven. Pulse sound of athletes under different loads varied.更多还原
