研究概览
简要总结
The aim of this study is to: (i) characterize the effect of repeated archery shots on the EMG parameters of certain selected upper limb muscles; and (ii) evaluate how manipulation of the initial two-second tension phase, in particular involving muscle stretching, affects these EMG parameters after repeated shots.
详细描述
EMG measurements will be collected for selected muscles in the shoulder joint and forearm, at points: initially at the beginning, after the athletes have performed 50 and another 50 archery shots, and finally after undergoing manual therapy. The main phase of muscle testing will take place in the Aiming phase.

结局指标
主要结局
Assessment of MVC.
时间窗: Each isometric muscle test lasts 3 seconds. The study is performed three times for each muscle.
Muscle EMG is an assessment of the electrical characteristics during the study, the electrical source of which is the muscle membrane potential, and the measured EMG potentials are measured in μV and the repetition rate of muscle motor unit firing measured in Hz, at the same time of the study.
Muscle stiffness
时间窗: Each Myoton application lasts 1 sec for one point. Three evaluations of one of the two points for one muscle are performed. It is assumed that the study with recording will last 30 seconds for one muscle.
Muscle stiffness - characteristic resistance to physical contraction, which deforms initially forming. Stiffness (N/m) was calculated as S = amax.mprobe/Δl.
