Does Core Activation on an Unstable Surface Affect Periscapular Muscle Activation?
Does Core Activation on an Unstable Surface Affect Periscapular Muscle Activation?
The core muscles contain various muscle groups that stabilize the shoulders, pelvis, and spine, and they play an important role as pivot points in extremity movements. It is known that core muscles stabilize the lumbar region and core stabilization affects muscle activation. İn addition conscious abdominal muscle activation during exercise performance is believed to promote greater scapular muscle activation through existing myofascial connections. Studies support the relationship between the scapular region and the core region.
Another aspect of rehabilitation is the use of unstable surfaces with exercise, since it is possible to increase neuromuscular demand without placing further overload on the musculoskeletal system.
Hypothesis originating from the investigation:
H1: Exercises performed with core activation on stable surfaces activate the muscles around the scapula more than exercises performed without core activation.
H2: Exercises performed with core activation on unstable surfaces activate the muscles around the scapula more than exercises performed without core activation.
H3: Exercises performed with core activation on unstable surfaces activate muscle activation around the scapula more than exercises performed on stable surfaces.
H4: Exercises performed without core activation on unstable surfaces activate muscle activation around the scapula more than exercises performed on stable surfaces.
Muscle activation of upper trapezius, middle trapezius, lower trapezius ve serratus anterior will be measured by superficial electromyographic measurement. Muscle activation according to SENIAM for each muscle will be evaluated.
Muscle activations will be measured during 4 different scapula exercises based on the literature. These exercises are: Inferior glide, External rotation in sitting, External rotation with standing elevation, Wall slide.
The specified scapula exercises will be performed on stable and unstable surfaces while the core region muscles are active and inactive. During the exercises, superficial EMG measurements of muscles will be recorded bilaterally.
All measurements will be made in 3 repetitions.
