Background: The sit and reach test is the most common flexibility test used in health related fitness test batteries. Objective: To examine and compare three different sit and reach tests as a measure of hamstring flexibility in 102 female students. Method: The traditional sit and reach test, the chair sit and reach test, the back saver sit and reach test, and passive straight leg raise were administered in three trials to all 102 students (mean (SD) age 22 (1) years) on the same day. Results: A Pearson correlation coefficient analysis was significant (p<0.01) for the traditional sit and reach test with back saver sit and reach test and flexibility of hamstrings (r = 0.45 and 0.65 for left and right legs, and 0.63 and 0.53 for left and right legs respectively). Also, the back saver sit and reach test for the left (p<0.01) and right (p<0.05) leg was significantly associated with hamstring flexibility (r = 0.37 and 0.25 for the left leg and 0.50 and 0.44 for the right leg respectively). Conclusion:The results indicate that the back saver sit and reach test produces reasonably accurate and stable measures of hamstring flexibility. Moreover, it appears that this test is a safe and acceptable alternative to the traditional and chair sit and reach tests as a measure of hamstring flexibility in young women.

Diagnostic study, Level I.

The purpose of this study was to measure isokinetically glenohumeral joint movement peak torque and work in professional basketball, volleyball, handball and baseball players and determine whether significant differences exist between the dominant and non-dominant extremity in athletes and controls. Eighty healthy professional overhead athletes (basketball, volleyball, handball and baseball players) and 20 controls were tested bilaterally on a CYBEX 6000 isokinetic dynamometer at 60 degrees and 180 degrees s(-1) for diagonal pattern of the glenohumeral joint. A standardized protocol and testing guidelines were strictly followed. The range of motion of internal rotation (IR) on the dominant side of baseball players was significantly smaller than those on the dominant side of basketball, handball and volleyball players, and controls (P<0.01). Flexion/abduction/external rotation were consistently higher on the dominant arm (8.5%) for peak torque at 60 degrees s(-1) in baseball players, and bilateral ratios were lower on the dominant arm (14.8%) for peak torque at 180 degrees s(-1) in basketball players. The results of this study are important for the application and interpretation of isokinetic data and flexibility and mobility characteristics on unilaterally dominant overhead athletes. Functional weakness in external rotators, mobility impairments in IR and muscle imbalance have been shown in the dominant arm of these overhead athletes.

All the treatment techniques are effective in decreasing the regional fat values of the patients with cellulites.

The results indicate that a jump-rope training program is a good conditioning method for overhead athletes because of its potential benefits to shoulder strength.

ObjectiveKerlan-Jobe Orthopaedic Clinic Shoulder and Elbow Score (KJOC-SES) is a subjective assessment tool to measure functional status of the upper extremities in overhead athletes. The aim was to translate and culturally adapt the KJOC-SES and to evaluate the psychometric properties of the Turkish version (KJOC-SES-Tr) in overhead athletes.MethodsThe forward and back-translation method was followed. One hundred and twenty-three overhead athletes completed the KJOC-SES-Tr, the Disabilities of the Arm, Shoulder, and Hand (DASH), and the American Shoulder and Elbow Surgeons Evaluation Form (ASES). Participants were assigned to one of the following subgroups: asymptomatic (playing without pain) or symptomatic (playing with pain, or not playing due to pain). Internal consistency, reliability, construct validity, discriminant validity, and content validity of the KJOC-SES-Tr were tested.ResultsThe test–retest reliability of the KJOC-SES-Tr was excellent with an interclass coefficient of 0.93. There was a strong correlation between the KJOC-SES-Tr and the DASH and the ASES, indicating that the construct validity was good for all participants. Results of the KJOC-SES-Tr significantly differed between different subgroups and categories of athletes. The floor and ceiling effects were acceptable for symptomatic athletes.ConclusionThe KJOC-SES-Tr was shown to be valid, reliable tool to monitor the return to sports following injuries in athletes.

Both hospital- and home-based exercise programs decreased joint symptoms and improved function in patients with knee OA.
