METHODS: Twenty-two male rowers participated in the experiment using a rowing ergometer (Concept2, USA). The experiment consisted of 3 tests examining the maximal power of the pull-ups (MPbpu). The movement mechanogram was registered with a specialized complex Noraxon\'s 3D MyoMotion (Noraxon Inc., USA). The software of the complex allowed calculation of the values of the joint angles from the accelerometer data. The Origin Lab 8.5 program was used for the mathematical and statistical processing of the signals from the mechanograms.
RESULTS: It was found that all experiment participants had a stepped controlled increase in the power of single bar pull-ups leading to a corresponding proportional increase in the frequency of rowing - test 1 and, conversely, a stepped controlled increase in the rowing frequency accompanied by a proportional increase in the power of the bar pull-ups - test 2. The involuntary dependence of the power and the rate was due to the peculiarities of the central cyclic movement programming, according to which the forces and durations of the active and passive bar pull-ups phases were interconnected and regulated together. The voluntary power-rate dependence control led to the breakdown of these links in the motor program of cyclic movements and to the separate control of these parameters.
CONCLUSIONS: Motor programs in cyclic movement may be created in the same pattern in tope level sport and recreation, as well in different environmental conditions - gym halls (movement simulators), professional and recreational water sport tracks.
方法:使用赛艇测功机(美国Concept2),有22名男性赛艇运动员参加了实验。该实验由3个测试组成,检查上拉的最大功率(MPbpu)。运动机械图已在专门的复杂Noraxon的3DMyoMotion(NoraxonInc.,美国)。复合体的软件允许根据加速度计数据计算关节角度的值。OriginLab8.5程序用于对来自机械图的信号进行数学和统计处理。
结果:发现所有实验参与者的单杆引体向上的力量都有逐步受控的增加,从而导致划船频率的相应比例增加-测试1和,相反,划船频率的阶梯式受控增加,伴随着杆式引体向上的功率成比例增加-测试2。功率和速率的非自愿依赖性是由于中央循环运动编程的特殊性,根据这一点,主动和被动杆上拉阶段的力量和持续时间是相互联系和调节在一起的。自愿的功率速率依赖性控制导致循环运动的电动机程序中的这些链接崩溃,并导致对这些参数的单独控制。
结论:循环运动中的运动程序可以在运动水平运动和娱乐中以相同的模式创建,以及在不同的环境条件下-体育馆(运动模拟器),专业和休闲水上运动跑道。
