Muscle strength and core endurance are both factors contributing to athletes’ performance and prevalence of injuries. There are no studies indicating the relationship between muscle strength around the shoul-der and knee joints and core endurance.The aim of our study is to de-termine the relationship between core endurance and isokinetic mus-cle strength of knees and shoulders of elite athletes. Seventy-one elite athletes (weight lifting, boxing, taekwondo, biathlon, and ice skating) (age, 18.13±2.9 years) were included in the study. Isokinetic muscle strength of shoulder internal-external rotation and knee flexion-exten-sion were determined by using an Isomed 2000 device. Core endurance of athletes was assessed using the Mcgill Core Endurance Tests. There was a relationship between the shoulder internal rotation and external rotation peak torque/body weight (PT/W) and all endurance tests ex-cept extension endurance tests. There was also a relationship between knee flexion PT/W and all core endurance tests. While there was a re-lationship between knee extension PT/W and extension endurance and the lateral bridge test, this relationship was not found with the flexor en-durance test. These results indicate that the upper and lower extremity muscle strength and core endurance of athletes are related with each other and must be evaluated and trained as a whole with each other.
