Relationship between shoulder complex strength and throwing velocity in club cricketers

Abstract

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.

Effect of different bowling surfaces on bowling speed of pace bowlers: A cross-sectional study

“…Participants included were asymptomatic and had no injuries, especially to the shoulder joint and back during 3 months before the testing. [11] 32 out of 41 participants had participated in at least state level tournament.…”

“…Participants were instructed to perform a warm-up of 15 minutes including running, stretching (static and dynamic stretches) & shadow deliveries. [11,13,14] Bowling facilities were pre-assessed for length, to con rm that each one is having a standard length of 20.12 m (22 yards). The edges of good length deliveries were marked with bowling cones at 3.8 to 5.8 m from Keeper's end.…”

Comparative Analysis between Effect of Shoulder Strength and Core Endurance on Bowling Speed in Pace Bowlers

“…[21] At bowling end, the gun was placed 5 m behind the bowling crease, pointing down at the middle stump at the bowler's end. [5] Set up of the radar gun is shown in Figure 1. Timing of 7 to 10 am of morning, session was selected to avoid exertion due to extremely hot weather.…”

“…During overhead action of shoulder, rotator cuff muscles play a key role and act in balanced and coordinated manner to maintain adequate glenohumeral joint congruency and stability. [4,5] Particularly, the external rotators develop an approximation force equal to body weight and control eccentrically on the upper arm to prevent joint distraction during overhead throwing motion. [6,7] Furthermore, the balance between external and internal rotation strength (muscle strength ratio) is important for normal shoulder joint function.…”

“…Participants included were asymptomatic and had no injuries 3 months before the testing. [5] Twenty eight out of 40 bowlers were associated with professional state level teams, rest of them had represented local cricket association within their respective age groups.…”
