“…Clearly, pain is an important item to be evaluated and, therefore, the subjects were evaluated with the VAS. This scale was used because it is considered to be a highly reliable, easy and fast instrument to use for such an evaluation goal 22,23 .…”

| Background: Previous studies have shown a relationship between shoulder posterior capsule tightness and shoulder pain in overhead athletes. However, this relationship has not been studied in tennis players. Objectives: Assessment of the shoulder range of motion (ROM), strength and posterior capsule tightness of skilled amateur tennis players who had complaints of dominant shoulder pain in comparison with tennis players without pain. Method: Fortynine skilled amateur tennis players were distributed in 2 groups: Control Group (n=22) and Painful Group (n=27). The first group was composed of asymptomatic subjects, and the second was composed of subjects with shoulder pain on the dominant side. These groups were evaluated to determine the dominant and non-dominant shoulder ROM (internal and external rotation), isometric shoulder strength (internal and external rotation) and posterior shoulder tightness by blind evaluators. Results: The ANOVA results indicated significant differences between the groups in the dominant shoulder ROM, posterior capsule tightness, external rotation strength and strength ratio (p<0.05). The intragroup analysis (dominant versus non-dominant) in the Painful Group displayed a significant difference for ROM, posterior capsule tightness and external rotation strength (p<0.05). Conclusions: The tennis players with pain in the dominant shoulder presented greater posterior capsule tightness, internal rotation deficit (ROM), external rotation gain (ROM) and deficits in external rotation strength than the tennis players without pain.Keywords:physical therapy; rehabilitation; tennis; rotator cuff; Shoulder Impingement Syndrome.

“…In the study of sprint canoe athletes, in which the demands during the stroke are unilateral, Humphries et al (2000) did not show significant differences between the members in the analysis of ER and IR; however, they demonstrated isokinetic strength imbalance between the DL and NDL for flexors and extensors of the shoulder joint. Isokinetic studies with adolescent athletes of other sports with unilateral requirements of upper limbs such as volleyball (Franceschini et al, 2016), handball (Dos Santos Andrade et al, 2013), tennis (Ellenbecker et al, 2003;Saccol et al, 2010), and baseball (Noffal, 2003;Hurd et al, 2011), also showed differences between the limbs, with the MD presenting higher values of PT of the ER and/or IR.…”

Abstract:Sprint kayak is water sport where stroke is the main movement for the kayak's propulsion, which is composed of cyclic and repetitive movements of the upper limbs. Considering the importance of generating movement and stabilizing the glenohumeral joint during the stroke, a detailed study of the shoulder's muscles is fundamental for improving sports performance and reducing injuries. The main objective of this study is to analyze the muscular performance of external rotators (ER) and internal rotators (IR) in the shoulders of adolescent sprint kayakers. The results demonstrated no significant differences between the limbs, whether for mean ER's and IR's peak torque values or for the external/internal rotators ratio. When analyzing the average values for the male and female sprint kayakers separately, the same results were observed. Conclusions: We concluded that the symmetrical bilateral upper limb demands and the no overhead movements during sprint kayakers' stroke can explain the absence of differences between the limbs' strength and the balance between ER and IR, respectively.

“…Furthermore, according to Mendonça et al [8], such differences are consequence of the gain in IR muscular strength of the DL due to repetitive acceleration movements during the strike. Other asymmetrical sports such as handball [22], tennis [23][24], baseball [25] and water polo [26] demonstrate a preference for the DL. When comparing IR and ER PT average value, IR muscles presented average values higher than the ER muscles at both assessed angular velocities.…”

Background: Volleyball is a sport characterized by short, intensive and explosive actions. In the performance of these repetitive movements, the shoulder joint receives the largest load. Therefore, a detailed assessment of biomechanics and muscle performance is fundamental in the evaluation, treatment and in prevention of shoulder injuries in volleyball athletes. Methods and Findings:Information from a database concerning the isokinetic evaluation of the shoulder's external and internal rotator muscles at the 60°/s and 180°/s angular velocities from 20 adolescent male volleyball athletes under 17 years of age was assessed. At a velocity of 60°/s the average values for internal rotators on the nondominant limb were significantly smaller than those of the dominant limb, and at a velocity of 180°/s both the internal and external rotators average values for the non-dominant limb were significantly smaller than those for the dominant limb. For the external-internal rotator ratio analyses, there was no significant difference between the limbs. Conclusions:In conclusion, the unilateral demands during typical movements in volleyball resulted in higher peak torque values for the dominant limb in comparison to that of the non-dominant limb. For the external-internal rotators ratio, no relevant differences were found between limbs, and the average values were within the parameters of normality.
