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.

在第一个阶段，（i）获得道德批准（ii）执行协议I所必需的材料； (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 forestry: It was shown That (i) Stimulation of brachioradialis (BR) caused a significant increase在手腕弯曲扭矩中。不仅激活的BR，而且远处的屈肌radialis（FCR）肌肉的弹性模量显着增加。 （ii）在自愿腕屈曲期间，手腕屈曲的弹性模量显着增加。 BR的弹性模式的增加，而EMG RMS值的增加略有下降。提交并表示为“前臂上皮相互作用的功能相关性：在2016年7月在芝加哥举行的芝加哥国际学会（ISEK）在2016年7月在芝加哥举行的Iniir Intriew iniir Incemiir Incemiir Intrike in Universir Intrike in trike Iniir，I）在芝加哥举行的Intormassions Intrastricismismiss In Vivo评估。 （ii）建立了计划工作的Yeditepe University，伊斯坦布尔，计划中的工作，设置II的设置（测试髋关节相互作用对髋部屈曲期间自愿性收缩期间大腿肌肉的影响），进行了初步工作，并在健康的年轻成年中完成了协议II的实验。
