Measure	Time frame
The aim of this study is to investigate the effect of a combined training intervention consisting of eccentric strength training and myofascial self-treatment using a foam roller on the structure and function of the Achilles tendon as well as on the running pattern in individuals with mid-portion Achilles tendinopathy. The following parameters will be assessed: pain, symptoms, function and activity, foot posture, neovascularization, ankle joint mobility, isometric plantar flexor strength, tendon thickness, muscle fiber length of the m. gastrocnemius medialis, stiffness of the m. gastrocnemius lateralis and medialis, and neovascularization. Pain will be measured using a VAS scale and an algometer; symptoms, function, and activity will be assessed using the VISA questionnaire; changes in foot posture will be measured with a force plate integrated into the treadmill; isometric strength and mobility will be measured using a CONTREX device; muscle fiber length will be assessed using Aixplorer ultrasound imaging, and neovascularization will be evaluated with an Esaote ultrasound system. To assess therapeutic framework conditions, selected questions from the German versions of the Helping Alliance Questionnaire (HAQ) and the Credibility/Expectancy Questionnaire (CEQ) will be used. The questionnaires will be administered at the beginning of the study at the same time point and again after three months, at the same time of day and by the same investigators. The measurements of stiffness using Myoton, pain using an algometer, mobility and strength using the ConTrex device, fascial length using Aixplorer ultrasound, neovascularization using Esaote, and running analysis using a treadmill with an integrated pressure measurement plate will also be conducted. The questionnaires will be collected a total of two times, while pain will be assessed using a VAS scale twice daily throughout the training period.	—
