Abstract Cricket-bowling performance is known to be influenced by speed of ball release and accuracy. Currently, training sessions typically involve fielding-specific drills and conditioning exercises. Scientific evidence for inclusion of a comprehensive yoga intervention in daily training and exercise sessions remains unexplored. The present study explored the effect of yoga on bowling performance and physical fitness in cricket bowlers. Sports fitness testing and training were conducted among 60 non-elite recreational-club male cricket players aged 13–25 years. Cricket-bowling speed was e valuated using a speed radar gun, accuracy with a test developed by Portus et al., cardiorespiratory endurance using the yo-yo intermittent recovery test, lower-extremity and trunk strength using a back-leg dynamometer, upper-limb power using a medicine ball–throw test, power using a vertical-jump test, and flexibility using a sit-and-reach test. In addition to bowling practice, the yoga intervention group (n = 30) performed pranayama and standing and prone asana, whereas the control group (n = 30) practiced conventional conditioning exercises, for 45 minutes/day, three times a week, for 12 weeks. Improvement in bowling speed, accuracy, cardiorespiratory endurance, muscle strength, and flexibility were comparable between the two groups. Statistically significant improvements in baseline scores in bowling speed, accuracy, cardiorespiratory endurance, muscle flexibility, strength, and power were comparable between the two groups of non-elite male cricket players. Bowling speed improved by 6.52% in the yoga group and by 5.18% in the control group. Bowling accuracy improved by 35.40% in the yoga group and by 31.29% in the control group. Additional research on long-duration intervention in elite players may help to establish the role of yoga in conventional cricket-bowling training.

Pace bowlers must often perform extended bowling spells with maximal ball release speed (BRS) while targeting different delivery lengths when playing a multi-day match. This study investigated the effect of an eight over spell upon pace bowling biomechanics and performance at different delivery lengths. Nine male bowlers (age = 18.8 ± 1.7 years) completed an eight over spell, while targeting different lengths (short: 7–10 m, good: 4–7 m, full: 0–4 m from the batter’s stumps, respectively) in a randomized order. Trunk, knee and shoulder kinematics and ground reaction forces at front foot contact (FFC), as well as run-up velocity and BRS were measured. Paired sample t-tests (p ≤ 0.01), Hedges’ g effect sizes, and statistical parametrical mapping were used to assess differences between mean variables from the first and last three overs. No significant differences (p = 0.05–0.98) were found in any discrete or continuous variables, with the magnitude of difference being trivial-to-medium (g = 0.00–0.73) across all variables. Results suggest pace bowlers sustain BRS through a single eight over spell while tolerating the repeatedly high whole-body biomechanical loads as suggested by maintaining the kinematics or technique at the assessed joints during FFC. Practically, the findings are advantageous for bowling performance and support current bowling load monitoring practices.

Bowling effectiveness is a key factor in winning cricket matches. The team captain should decide when to use the right bowler at the right moment so that the team can optimize the outcome of the game. In this study, we investigate the effectiveness of different types of bowlers at different stages of the game, based on the conceded percentage of runs from the innings total, for each over. Bowlers are generally categorized into three types: fast bowlers, medium-fast bowlers, and spinners. In this article, the authors divided the twenty over spell of a T20I match into four stages; namely, Stage 1: overs 1-6 (PowerPlay), Stage 2: overs 7-10, Stage 3: overs 11-15, and Stage 4: overs 16-20. To understand the broad spectrum of the behavior of game variables, a Quantile Regression methodology is used for statistical analysis. Following that, a Bayesian approach to Quantile Regression is undertaken, and it confirms the initial results.

Modern technology plays a major role in all aspects of many sports, from training to media commentary and video referees. The work contained in this report is focused on the ball launching devices which are prolific in a number of these sports such as cricket, baseball, tennis and football. These devices are used as aids to enhance the intensity and quality of a training session whilst also enabling batsmen to train without requiring the presence of a bowler. Technological advances, such as visualisation and programmable sessions, have been included in the design of baseball pitching machines but not within the domain of cricket training. The ongoing research presented in this paper highlights a shortfall in the current market and begins to develop a novel cricket bowling system. This includes a fully computer controllable environment capable of creating any cricket bowling delivery synchronised with an accurate visualisation of the bowler throughout the delivery process.
