Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In the treatment of Achilles and patellar tendinopathy, it has been shown that eccentric exercise training has positive effects on pain and function, and supports the improvement in the structural and mechanical properties of the tendon. This success of eccentric training in managing lower extremity tendinopathies has encouraged researchers to conduct more scientific studies to develop evidence-based eccentric training guidelines for the conservative treatment of tendinopathies in the shoulder region. Studies showing that eccentric exercise training has positive effects on pain and function in rotator cuff pathologies have begun to take their place in the literature. In some studies, it has been stated that eccentric exercises are a safe and tolerable approach even in patients with rotator cuff tendinopathy who are candidates for arthroscopic subacromial decompression surgery and reduce the number of patients who are candidates for surgery. Again, in a systematic review-meta-analysis study involving individuals with rotator cuff tendinopathy, it was once again summarized that eccentric training has positive effects on pain and function, but it was stated that more studies are needed on this subject.
The HSR training is the repetitive gradual and slow contraction of the muscle against the heaviest possible load that the person can tolerate. In this training, the focus is more on the concentric and eccentric phases of the movement, and these phases are requested to be completed slowly in 3 seconds. As a result, the concentric/eccentric phase of an exercise repetition is performed with maximum weight in 6 seconds in total. There is scientific evidence in the current literature that slow resistance training has positive effects on symptoms and tendon structure in patella and Achilles tendinopathy. Beyer et al. compared eccentric exercise training and HSR training in Achilles tendinopathy and reported that both trainings had equally positive effects. However, scientific studies investigating the effects of slow resistance training in rotator cuff pathologies are mostly new and few in number. In a recent single-blind randomized controlled feasibility study conducted on 22 individuals with rotator cuff-related subacromial shoulder pain, the effects of slow resistance training in addition to traditional physical therapy program and traditional physical therapy program were compared. Schydlowsky et al. In their study comparing the effects of a supervised and home-based physiotherapy program in subacromial impingement syndrome, they did not directly examine the effects of slow resistance training, but used the slow resistance training procedure for the rotator cuff muscles.
Although exercise training is known as an effective intervention method in the treatment of rotator cuff/subacromial impingement problems, there is no definite consensus on which type of exercise is more effective. However, when previous literature studies from 2022 were examined, a single pilot study was found that examined the effect of specific slow resistance training on symptoms in rotator cuff tendinopathy; No studies could be found comparing specific slow slow resistance training with other exercise interventions. The aim of this thesis, which the investigators planned in the light of this information, is to analyze and compare the effects of heavy slow resistance training and eccentric exercise training on pain, function, supraspinatus tendon structure, muscle strength, range of motion, subjective perception of improvement and treatment satisfaction in individuals with subacromial shoulder pain associated with rotator cuff tendinopathy.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Heavy slow resistance group (HSR group)
The investigators are planning a 6-week rehabilitation program, 2 days a week. The same physiotherapy and home exercise program will be applied to both groups. The physiotherapy and home exercise program will include patient education, stretching, range of motion and posture exercises. Resistance training will consist of different exercise principles but the same types of exercises. Resistance training: Dumball will be used as exercise equipment. Exercise intensity determined using the Numerical Pain Rating Scale (NPRS).
Individual loading will be made according to the amount of weight. The maximum amount of pain producing pain less than 4 on the Numerical Pain Assessment Scale will be determined as exercise intensity. It will include 3 different exercises: 1) Full can. 2) External rotation in side lying. 3) Internal rotation in side lying.
Heavy slow resistance training
Patients will perform the exercises in the concentric and eccentric phases with the maximum amount of weight tolerated at a rate of 3 seconds/repetition. The number of sets\*repetitions is given below. 2-3 minutes rest between sets will be given.

Eccentric exercise training group (EE group)
The investigators are planning a 6-week rehabilitation program, 2 days a week. The same physiotherapy and home exercise program will be applied to both groups. The physiotherapy and home exercise program will include patient education, stretching, range of motion and posture exercises. Resistance training will consist of different exercise principles but the same types of exercises. Resistance training: Dumball will be used as exercise equipment.

Eccentric exercise training
Among the patients in the eccentric exercise group, only the eccentric phase of the exercises in the HSR group, will be asked to actively engage with the affected party. The eccentric contraction rate will be set to 6 seconds. Each exercise will be done 3 sets of 15 repetitions. In the next week, progress will be made in exercise intensity according to tolerance and 500 g will be added to the previous weight.
will be continued. If patients cannot tolerate the new weight or there is an increase in pain, the same weight will be continued for another week.
