Accessibility of Motion Capture as a Tool for Sports Performance Enhancement for Beginner and Intermediate Cricket Players.

Motion Capture (MoCap) has become an integral tool in fields such as sports, medicine, and the entertainment industry. The cost of deploying high-end equipment and the lack of expertise and knowledge limit the usage of MoCap from its full potential, especially at beginner and intermediate levels of sports coaching. The challenges faced while developing affordable MoCap systems for such levels have been discussed in order to initiate an easily accessible system with minimal resources.

Visual-perceptual training with motor practice of the observed movement pattern improves anticipation in emerging expert cricket batsmen.

This study addressed the paucity of evidence of whether visual anticipation can be improved in emerging experts in striking sports. Twelve emerging expert batsmen from a state cricket squad were equally randomised into intervention and control groups. They were pre-and-post tested on a video temporal occlusion test of a fast bowler, as well as transfer tests of different fast and slow bowlers. The intervention group received two sessions per week of point-light display temporal occlusion training with motor practice of the observed bowler's action over a 4-week period. The control group completed only the testing phases. Batting averages before, during, and after the study were recorded for both groups. The intervention group, but not the control group, improved anticipation to significantly above chance level across pre-to-post-tests based upon pre-ball flight information. The intervention, but not the control, transferred their learning to anticipate significantly above chance level based upon pre-ball flight information across different fast and slow (spin) bowlers. Batting average of the intervention group was higher than the control group during the study. Findings indicate that the intervention can improve anticipation in emerging expert batsmen, beyond sport-specific practice. This improvement may benefit competition performance, but further evidence is required.

A descriptive analysis of batting backlift techniques in cricket: Does the practice of elite cricketers follow the theory?

One of the first principles of cricket batsmanship that is coached from a young age is to play with a straight bat. Limited studies to date have examined whether top international batsmen use this traditionally described technique. Accordingly, we performed a descriptive, observational study of the backlift technique adopted by 65 of the most successful batsmen of all time, based on their career averages, strike rate and runs scored. The batsmen were divided into two groups depending on whether they played the game before or after 1954. Surprisingly, more than 70% of these successful batsmen did not adopt the traditionally taught technique. Instead, they adopted a more looped action in which the initial movement of the bat was in the direction of the slips, and in extreme cases it was either towards the gully/point region or to have the face of the bat directed towards the off-side. This suggests that traditionally taught batting coaching techniques may hinder, rather than enhance future cricketing performance. Since the vast majority of cricketers are not coached in this technique, this finding probably indicates that this looped technique is likely a contributing factor to effective batsmanship.

Reliance upon contextual information can impede visual anticipation.

This study investigated whether skilled batsmen in a state cricket pathway could anticipate ball types when congruency of field-placings was manipulated with a bowler's action. Twenty-four male cricket batsmen were recruited who had played either first-class cricket (n = 6), were part of under 17 (n = 8) or under 19 (n = 10) state cricket squads. Participants completed a video-based temporal occlusion test where they were required to anticipate ball types from a swing bowler. In condition one, contextual field-placing information was presented to be congruent with the delivery type and bowler's action, whilst in condition two it was incongruent. Results did not reveal skill level differences across conditions for anticipation. In the congruent condition, all skill groups predicted above the chance level at the beginning and end of the bowler's delivery stride. In the incongruent condition, first-class players predicted above chance at the beginning of the bowler's delivery stride, and to a higher magnitude above chance compared to other skill groups at ball release. Under 17 and 19 players could not predict above chance at the start of the bowler's delivery stride with their magnitude of prediction lower than first-class players at ball release. Results indicate skilled batsmen find it challenging to integrate contextual and kinematic information to anticipate. This is likely due to greater emphasis placed upon contextual information in part supplied by data analysts. Findings have theoretical and practical implications respectively for lower body positioning for bat-ball interception and perceptual training to improve pick-up of kinematic cues.HIGHLIGHTSSkilled batsmen in a high-performance state cricket pathway could integrate congruent field-placings and bowler kinematics to anticipate ball types.First-class batsmen could integrate incongruent field-placing information to the start, but not the end, of the bowler's delivery action to anticipate ball types.Under 17 and 19 batsmen could not integrate incongruent field-placings to bowler kinematics to anticipate ball types.Skilled batsmen who cannot use kinematic information to anticipate ball types should be given visual-perceptual simulation training to accelerate performance.

Sources of information pick-up for anticipation by skilled cricket batsmen.

This study investigated whether skilled West Indian cricket batsmen could use contextual and kinematic information to anticipate the type of ball being bowled. Thirty-one participants were recruited that formed first class (n = 10), elite club (n = 10), and elite youth representative (n = 11) groups. Each group completed a video temporal occlusion batting test under two conditions. Condition one presented bowler kinematic information; that is, occlusion occurred at back-foot, front-foot, and ball release, with a no occlusion control. Condition two presented game contextual information in the form of field placings that was congruent with the ball types prior to temporal occlusion trials. Results revealed no significant skill group differences in the timing of information pick-up under kinematic or contextual conditions. Prediction accuracy for all skill groups was at guessing level at each temporal occlusion that presented kinematic information, but was above chance at no occlusion. Prediction accuracy for all skill groups increased to above guessing level at advance cue temporal occlusions when contextual information was provided. Findings indicate that this group of skilled batsmen did not use kinematic information for anticipation in this temporal occlusion task, but relied heavily upon contextual information. An implication of this study is that skilled batsmen should be targeted for visual-perceptual training to pick-up contextual and kinematic information to guard against deception from the latter that can negatively impact batting performance.

Analysis of Cricket Ball Type and Innings on State Level Cricket Batter's Performance.

Background: The aim of this investigation was to compare the type of cricket balls utilized and innings on cricket batting performance in the First-Class Australian competition. Methods: Batting performance measures of 43 state level cricket batters were collected from two seasons of the Sheffield shield tournament (N = 60 games) that incorporated both Kookaburra™ (n = 30 games) and Duke™ (n = 30 games) cricket balls. Results: First-innings batting performances were significantly greater for the average number of runs scored (37.5 ± 13.4 vs. 31.2 ± 11.3), balls faced (60.7 ± 26.2 vs. 49.9 ± 23.6), boundary 4s (3.8 ± 1.9 vs. 2.9 ± 1.4), and boundary 6s (0.2 ± 0.3 vs. 0.1 ± 0.3) scored per game (p < 0.05), as well as centuries scored (5.74 ± 8.56 vs. 1.49 ± 5.14%) compared to second innings performances (p < 0.05). There were no differences for any batting performance measures as a result of ball type (p > 0.05). However, significantly more wickets were taken by pace bowlers during Duke™ ball games (85.0 ± 12.8 vs. 76.4 ± 13.9%), while relatively more wickets were taken by spin bowlers during Kookaburra™ ball games (14.2 ± 12.5 vs. 22.0 ± 14.1%; p < 0.05). Conclusions: Cricket batting performance was comparable in games involving the Kookaburra™ or Duke™ ball. However, pace bowlers were more successful transferring their skill to the Duke™ ball, while spin bowlers were more successful with the KB™ ball. Subsequently, batters may be able to effectively adapt their movement technique, and transfer their skill to the Duke™ ball conditions. Future research is suggested to examine the influence of the cricket playing surface's deterioration on cricket batter's interceptive performance.

Emergence of Skilled Behaviors in Professional, Amateur and Junior Cricket Batsmen During a Representative Training Scenario.

The aim of this study was to explore the emergence of skilled behaviors, in the form of actions, cognitions and emotions, between professional state level cricket batters and their lesser skilled counterparts. Twenty-two male cricket batsmen (n = 6 state level; n = 8 amateur grade club level, n = 8 junior state representative level) participated in a game scenario training session against right arm pace bowlers (n = 6 amateur senior club). The batsmen were tasked with scoring as many runs as possible during a simulated limited-overs game. The actions, cognitions, and emotions of each batsmen were recorded in situ with findings showing differences between state level players and those lesser skilled. State level batsmen played more scoring shots and scored more runs, underpinned by superior bat-ball contact and technical efficiency. Furthermore, the state player's cognitive evaluations of their own performance differed from junior batters, with more reported strategies based on an external outcome focus, such as where to score runs, rather than a focus on internal processes, such as making technical changes. State level batsmen also reported lower levels of nervousness compared with junior level batsmen. These results highlight the importance of viewing the emergence of skilled behavior as multi-faceted, rather than simply the acquisition of superior execution and technical proficiency.
