“…Thus, in order to prevent injuries, the muscular stabilizers of the shoulder complex (rotator cuff muscles) play a significant role (Paine &Voight, 2013). However, despite an increase in the amount of research on the area of isokinetic strength and sport performance (Cools et al, 2007;Cerrah et al, 2012), there is still a scarcity of studies on cricket (Derbyshire, 2007;Freeston et al, 2007;Freeston et al, 2016).…”

Cricket is a game of immense physical prowess requiring high levels of fitness and skill. Purpose: The aim of this study focused on examining the relationship between shoulder concentric strength and throwing velocity amongst club cricketers. Method: The study used a quantitative, cross-sectional design. A convenient sample of 40 male university cricketers was tested. Shoulder concentric strength was measured at 60º•sec-1 and 90º•sec-1 using an isokinetic dynamometer. Throwing velocity was measured using a Speed Gun. Results: Significant correlations were found between peak torque during concentric internal rotation at 60º•sec-1 and maximal throwing velocity for the first team (r = 0.72; p = 0.01), second team (r = 0.67; p = 0.03), third team (r = 0.73; p = 0.01) and fourth team (r = 0.69; p = 0.02). The correlation between strength ratio at 60º•sec-1 and maximal throwing velocity was also significant for the first team (r = 0.76; p = 0.01), second team (r = 0.83; p = 0.002), third team (r = 0.70; p = 0.02) and fourth team (r = 0.94; p = 0.0001). Conclusion: The shoulder concentric internal rotators play a significant role in throwing velocity of club cricketers.

“…There are several limitations that need to be considered when interpreting the results of this literature review. First of all, the studies included had rather small study populations, ranging from 14 to 120 participants in able-bodied sports ( 27 , 42 ), and 13 to 65 participants in wheelchair sports, ( 33 , 50 ) which limited the power of each of the studies. This may have obscured differences between groups for the assessment of validity, especially in activities with limited reliability, such as throwing precision.…”

BackgroundIn Paralympic sports, classification of athletes based on the impact of impairments on the ability to perform is needed, to prevent a one-sided and predictable outcome of the competition in which the least impaired athlete has the best chance to win. Classification is developing from expert opinion based to evidence based. In wheelchair court sports, there is evidence to support the impact of impairment on wheeled mobility, but not on ball handling. To assess the impact of impairment on the ability to perform ball-handling activities, standardised tests for ball handling are needed.PurposeTo assess if reliable and valid standardised tests for the measurement of ball-handling proficiency in a wheelchair or able-bodied court sports exist; to assist in the development of Evidence-Based Classification (EBC) in wheelchair court sports according to the guidelines of the International Paralympic Committee (IPC).MethodsThe review was conducted according to the Meta-Analysis of Observational Studies in Epidemiology (MOOSE) statement. Search terms used were “wheelchair,” “ball,” “ball sports,” “test,” and “performance.” Databases searched were Medline, Embase, PubMed, and Sport Discus. Study quality was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology checklist.ResultsTwenty-two articles were included. Foundational Movement Skills in ball-handling proficiency were assessed. Tests for throwing maximal distance showed sufficient reliability and validity. Precision in throwing showed low-to-moderate reliability and conflicting results in validity. Throwing techniques differed between studies. Dribbling the ball showed high reliability, but conflicting results in validity.ConclusionsTests for throwing maximal distance, throwing precision, and dribbling the ball can be used in standardised tests for activity limitation in wheelchair court sports. However, tests need to be adapted and standardised and then reassessed for reliability and validity in athletes with and without arm impairment.

“…Because a complex series of synergistic muscle actions involving antagonistic and agonistic muscles are performed during running, sitting-based activities may not be appropriate for assessing performance in soccer players [55], and isokinetic tests may not necessarily reflect the movement of the limbs involved in the different running tasks in soccer [56]. However, studies investigating the relationship between technical components of the game, such as the soccer kick [57,58] and throw-ins [59], and isokinetic strength show moderate to strong positive correlations between these variables. Therefore, isokinetic strength may be a better determinant of technical skills than field conditioning and performance in soccer.…”

The current study investigated the relationship between isokinetic knee strength, jump performance, agility, linear and repeated sprinting capacity and Yo-Yo IR1 test performance and the fatigue indices of some of these variables in semi-professional soccer players. Twenty semi-professional soccer players participated in this study, performing 6 tests: bilateral concentric isokinetic strength tests of the knee extensors and flexors (60◦.s-1 and 300◦.s-1), jump tests (countermovement, squat and repeated jumping), linear sprints (10 and 30 m), agility (Illinois test), Bangsbo repeated sprints (7 x 34.2 m), and Yo-Yo IR1 tests. While no isokinetic variables were significantly correlated with field test results, some jump test results correlated with AgiWB, 10- and 30-m sprint times, RSTMEAN and FIRS. Furthermore, the knee isokinetic strength (60◦.s-1 and 300◦.s-1) indices and jump capacities demonstrated moderate to strong relationships with each other. In addition, AgiWB correlated with the 10-m sprint times and RSTMEAN, 30-m linear sprint times correlated with 10-m sprint times and AgiWB, and FIRS and RSTMEAN correlated with the Yo-Yo IR1 test results. The results suggest that power output during CMJ and RJ tests and not isokinetic knee strength are informative in determining field conditioning parameters for semi-professional soccer players.
