The Role of the Internal Rotation of the Upper Arm in Javelin Throwing
نویسندگان
چکیده
We performed a kinematic and inverse dynamic study with javelin throwers in order to assess the role of the internal rotation of the upper arm in javelin throwing and then compare the findings to baseball throwing. On the one hand, the results show an equal behaviour of the angular velocity, torque and power curves compared to baseball pitching. The evaluated peak values differ on the other hand. Hence, the different release velocities in baseball pitching and this study could serve as an explanation for the different values, which can vary enormously.

Glenohumeral joint: internal and external rotation range of motion in javelin throwers.
OBJECTIVE To assess differences in glenohumeral joint rotatory range of movement in javelin throwers between the throwing and non-throwing arm. METHOD A universal 360 degrees goniometer was used to assess glenohumeral joint external and internal rotation range in 90 degrees of shoulder abduction in a group of ten senior international javelin throwers. RESULTS Both arms had significantly gre...

Purpose: In recent years, many people show interest to Paralympics competition because it is dedicated to athletes with disabilities. In order to affect the throwing, static stretching can be applied on the two muscles, i.e. pectoralis major and latissimus dorsi that play an important role in the arm acceleration phase. Normally, before sport activities, static stretching is applied. Stretching...

Objective: Glenohumeral Internal Rotation Deficit is one of the important risk factors in throwing athletes that can cause adverse effects on glenohumeral joint biomechanics during throwing activity and overhead activity. Methods: In this descriptive study, 30 male student Hanballers (age=18 to 25 years) were categorized into healthy (n=15) and Glenohumeral Internal Rotation Deficit (n=15) gro...

Background and Objectives: Glenohumeral internal rotation deficit (GIRD) is one of the most important risk factors for overhead-throwing athletes and adversely affects the biomechanics of the Glenohumeral joint during overhead-throwing motions. The aim of this study was to review all the articles performed in the field on the effect of corrective exercises on pain, function, proprioception, and...
متن کاملComparing strength and range of motion of the upper limb with AV fistula access with the contralateral upper limb among patients treated with hemodialysis
Introduction: The arteriovenous (AV) fistula is a gold standard method for safe and effective repeated vascular access for patients on hemodialysis (HD). The patients, with AV-fistula access in their upper limb, have some limitations in using the involved limb both in daily living and during the dialysis process. The aim of this study was to compare range of motion (ROM), muscle strength and...
