Investigation of the Relationships Between Core Muscle Endurance, Pelvic Oscillations and Pelvic Width in Athletes and Sedentaries

There are many physical, physiological, psychological and sociological differences between athletes and sedentary individuals. These differences are evident due to the motoric characteristics brought about by the sports they do. While the differences revealed by the studies in the literature are in a relationship among themselves, this has an effect on the sportive performance of the person.

Core muscles are the muscles that provide both stability and mobility of the trunk in which local and global muscles work in coordination. The endurance and strength of the core muscles affect not only trunk movements but also distal extremity movements and functionality. The endurance of the core muscles, which is important for movement and balance in athletes and sedentary individuals, can also be the cause of some injuries when it is deficient.

During gait, the pelvis makes sinusoidal up-and-down movements in the frontal and sagittal planes and rotational movements in the transverse plane. These movements are provided by the local and global muscles surrounding the pelvis and hip joint. Reduction of pelvic oscillations in the normal gait pattern may lead to decreased energy expenditure and increased muscle force production. Pelvic oscillations should be sufficient and pelvic control should be appropriate for walking, running, activities of daily living and sportive performance to be correct and economical. As a result of studies showing that pelvic width has effects on the physical activities of individuals, anatomical anthropometric characteristics of the pelvis also have an effect on energy consumption in athletes and sedentary individuals.

When the literature was reviewed in this direction, no study was found that examined the relationship between core muscle endurance, pelvic swing and pelvic width in athletes and sedentary individuals. In athletes, holistic performance parameters and anthropometric characteristics or adaptations are important for the efficiency of sports. Likewise, in sedentary individuals, these characteristics are important for achieving activities of daily living. Our study is planned to examine the relationships between core muscle endurance, pelvic swing and pelvic width in athletes and sedentary individuals and to make a comparison between these two groups. As a result of the study, this gap in the literature will be filled and the relationship between core muscle endurance, pelvic swing and pelvic width of athletes will be examined and possible differences between athletes and sedentary individuals will be revealed.
