“…5 Estudos não mostraram os efeitos negativos da falta de arremesso e dos implementos com excesso de peso no controle do arremesso ou risco de lesão. [11][12][13] Um estudo biomecânico recente mostra que esses arremessos podem produzir variações na cinemática (especificamente nas velocidades do braço, tronco, pelve e ombro). Nenhum aumento na cinética do braço e no esforço máximo de arremesso de crowhop com os mesmos implementos pode aumentar a velocidade angular do ombro IR e o torque em varo do cotovelo.…”

“…Muitas vezes tem variação na ADM do ombro no arremesso, uma rotação mais lateral e uma ADM de rotação medial diminuída. 11 Uma retroversão umeral instigada que basicamente causa uma mudança uniforme no movimento, o membro estendido, a articulação de rotação externa, causa redução da rotação interna. No entanto, uma contração subsequente da cápsula do ombro pode resultar em um RI glenoumeral encurtado sem um realce acentuado no RE; adução horizontal atenuada torna a articulação altamente sujeita a lesões.…”

INTRODUCTION: The shoulder joint is the most complex joint in the human body, the most mobile and least stable in relation to other joints. In bowling, using the upper extremity in the throwing motion is one of the most challenging tasks. In order to generate a precise throw, the numerous anatomical components involved in the overhead throwing motion must be coordinated. Shoulder muscular strength is a key component of excellent bowling, and the strength of various shoulder muscle groups influences bowling speed. Therefore, it is essential that bowling players exert strength in their performance. This lacks bone stability and sacrifices stability to increase mobility. OBJECTIVES: To analyse the effects of strengthening the shoulder internal rotators and the muscular energy technique of the shoulder external rotators on bowling speed in fast cricket players. METHODS AND MATERIALS: Participating rapid cricket players from sports field aged 18-30 years, were recruited and then randomly allocated into two groups: strengthening group and MET group. The strengthening group received muscle strengthening for the internal rotators of the shoulder and the MET group received the muscle energy technique for the external rotators. All the exercise interventions was involved physiotherapist supervision session with 12 repetitions and 3 sets 5 days per week up to eight weeks. Range of motion was measured by goniometer instrument and bowling speed was assessed by speed gun. All outcomes were assessed at baseline, 2nd week, 4th week and 8th week after the intervention with ANOVA of repeated measures. RESULTS: Of the 30 participants evaluated, the mean age, height, weight and BMI were, respectively, 21.40±2.36 years old, 1.74±0.09m, 71.80±16.77kg and 23.57±4.20Kg/m2 for the strengthening group and 22.53±1.55 years old, 1.70±0.04m, 62.47±8.02kg, 21.49±2.63Kg/m2 for the MET group.There was a statistically significant difference for all outcomes regarding the measured times between the two intervention groups. However, in the strengthening group, there was a greater effect size for internal rotation ROM (1.99 in the strengthening group versus 1.42 in the MET group) and for bowling speed (1.52 versus 1.39). External rotation ROM had a greater effect size in the MET group (1.66 for the MET group and 1.16 for the strengthening group). CONCLUSIONS: The result of study concludes that a significant improvement in shoulder internal rotators and external rotators strength leads to improve bowling speed, so the shoulder strength training protocol and muscle energy training can be incorporated for increasing the speed of the bowler.

The purpose of this study was to find the correlation between the hand grip strength and the shoulder power in the intercollegiatemale cricket players of age group 17, 18 and 19. A sample of 75 subjects were assessed, which includes 17 subjects of 17 years; 35 subjects of 18 years and 23 subjects of 19 years. All the participants were assessed for the height, weight, BMI, the hand grip strength of the dominant hand and the non-dominant hand was assessed with a calibrated hand held dynamometer and the shoulder power was assessed with a Closed Kinetic Chain Upper Extremity Stability Test. The results of this study indicated that there is positive correlation between the hand grip strength and the shoulder power in cricket players. The conclusion of the study is, as there is a positive correlation between hand grip strength and shoulder power, while training cricket players both should be given due importance for better performance in the game.

“…Static and dynamic stabilizers allow great range of motion of the shoulder and if these are damaged by trauma or overuse the shoulder has an increased risk of injury. Particularly the muscles that comprise the rotators of the shoulder are re-sponsible for well-coordinated and synchronized actions in sports such as baseball, badminton, and tennis that involve repetitive overarm motions [1][2][3][4][5]. However, repetitive and forceful overarm movements, and large differences between agonist and antagonist muscle strength are related to the highest rates of injury in the shoulder joint [1][2][3]6].…”

“…However, repetitive and forceful overarm movements, and large differences between agonist and antagonist muscle strength are related to the highest rates of injury in the shoulder joint [1][2][3]6]. During overhead and throwing movements, high torque of the Internal Rotators (IR) without proper balance of the External Rotators (ER) may lead to imbalances of this complex [1,3,4,7]. Objective evaluations using Isokinetic Dynamometers are effective in testing shoulder ER and IR strength.…”

BACKGROUND: Independent peak torque (IPT) ratios may lead to misinterpretation of shoulder rotator imbalances. OBJECTIVE: To compare shoulder rotator IPT conventional ratio (CR) and dynamic control ratio (DCR) with ten-degree angle specific torque (AST) CR and DCR. METHODS: Twenty healthy adult males (24.65 ± 2.4 yrs) performed concentric (C) and eccentric (E) internal rotation (IR) and external rotation (ER) of the right shoulder on an isokinetic dynamometer at 60 • /s and 180 • /s through 150 • of ROM. RESULTS: IPT DCR was significantly different than AST DCR at several angles at both test speeds. IPT CR were not significantly different than any AST CR at either speed. The last 3 ten degree AST DCR were also compared. AST DCR was significantly different at two angles at 60 • /s and at three angles at 180 • /s. CONCLUSION: DCR analysis should use a ten degree AST interpretative approach in order to avoid erroneous interpretations of shoulder rotator strength imbalances. IPT ratio tests should only be used to calculate CR.
