研究概览
简要总结
The aim of this study was to: (i) assess the impact of maximal muscle strength and stiffness on EMG and Myoton parameters for selected upper limb muscles; and (ii) assess how manipulation of the initial 2-s tension phase, in particular involving muscle stretching, affects these EMG and Myoton parameters during karting training.
详细描述
EMG and Myoton measurements will be performed on selected muscles of the shoulder joint and forearm during karting drivers' training, initially at the beginning, after the athletes perform their first 8-minute run, after manipulation and after another 8-minute run.

结局指标
主要结局
Assessment of MVC.
时间窗: The study will be conducted 4 times during one training session (before the intervention, after the intervention, after race 1 and after race 2). Each isometric muscle test lasts 3 seconds.
Muscle EMG is an assessment of electrical characteristics during the test, the electrical source of which is the muscle membrane potential, and measured in μV.
2 Assessment of MVC.
时间窗: The study will be conducted 4 times during one training session (before the intervention, after the intervention, after race 1 and after race 2).Each isometric muscle test lasts 3 seconds.
Muscle EMG is an assessment of electrical characteristics during the test, which is measured by the repetition frequency of muscle motor unit discharges, which is measured in Hz, at the same time of the test.
3. Muscle stiffness
时间窗: The study will be conducted 4 times during one training session (before the intervention, after the intervention, after race 1 and after race 2). Each Myoton application lasts 1 sec for one point.
Muscle stiffness - characteristic resistance to physical contraction, which deforms initially forming. Stiffness (N/m) was calculated as S = amax.mprobe/Δl.
