During the first period, (i) ethical approval was obtained (ii) materials necessary to perform Protocol I were prepared; (iii) setup was established with (iv) preliminary experiments, (v) experiments of Protocol I were performed and (vi) data was analyzed.The results of Protocol I testing the effects of activity of an elbow flexor on the wrist joint supported our hypotheses on functional relevance of epimuscular myofascial force transmission for forearm: It was shown that (i) stimulation of brachioradialis (BR) caused a significant increase in wrist flexion torque. Elastic modulus of not only activated BR but also distant flexor carpi radialis (FCR) muscle increased significantly. (ii) During voluntary wrist flexion, elastic modulus of a wrist flexor, FCR significantly increased. Elastic modulus of BR increased, as well while the increase in the EMG RMS values were slight.Results were submitted and presented as ‘Functional Relevance of Epimuscular Interactions at Forearm: In vivo Assessments with Ultrasound Elastography’ in the International Society of Electromyography and Kinesiology (ISEK) Conference in Chicago in July 2016.Data was also presented in (i) Katip Celebi University, Izmir, Turkey and (ii) Yeditepe University, Istanbul, Turkey.Additional to the planned work, setup of Protocol II (testing the effects of inter-antagonistic interactions on thigh muscles during hip flexion voluntary contraction) was established, preliminary works were performed, and the experiments of Protocol II were completed in healthy young adults.

在获得FIR屈服的过程中（II）制备了基本方案I所必需的材料；腕部在腕关节上的肘部屈肌在前臂上的肌膜传播的相关性：（i）刺激腕骨（BR）在腕部屈曲d（II）显着增加。腕部屈曲的弹性模量显着增加。 2016年7月在芝加哥举行的肌电图学会（ISEK）会议。建立了抗抗流相互作用对大腿拉伸髋部屈曲自愿收缩的影响，进行了初步工作，在健康的年轻人中完成了protoc Off OL II。
