Previous experiences can influence individual cricket spin bowlers' perceptions of affordances in the performance landscape.

The ecological dynamics framework emphasises that movement solutions are guided by the relationship that exists between the performer and their environment, scaled to an individual's own action capabilities. This suggests that representative practice tasks should be used in high performance settings to encourage individually optimised movement solutions for both team and individual sports. This study specifically focuses on individual cricket spin bowlers and aims to understand the influence of their prior learning experiences on their perceptual attunement strategies when tasked with performing on a familiar Australian cricket pitch and a less familiar bespoke international (Indian) pitch. Two right hand leg spin bowlers that were part of a group of eight emerging expert spin bowlers were chosen for individual analysis. Bowler A reported 80 prior experiences of bowling on subcontinental (i.e., India, Pakistan, or Bangladesh) pitches whereas Bowler B had only 20 prior experiences. Overall, both bowlers' outcome performances either met or exceeded their expectations. Bowler A chose to calibrate his bowling style on the less familiar pitch to improve the fit between his delivery characteristics and the environmental pitch conditions, whereas Bowler B maintained his bowling style, even though he recognised a difference in the pitch conditions. Therefore, Bowler A maintained stable performance outcomes by implementing flexible movement solutions. In contrast, while Bowler B achieved his expected performance outcomes, his lack of diverse learning experiences may limit his action capabilities, although more performance trials are needed to confirm this conclusion. Regardless, this study demonstrates that there is valuable information in knowing how a player achieves a successful result, which should be coupled with performance outcomes to help create individualised development strategies.

Examining environmental constraints in sport: Spin characteristics of two cricket pitches with contrasting soil properties.

In the sport of cricket, the pitch is an organic surface that represents an important environmental constraint. While the soil properties of the pitch are known to influence the pace and bounce of medium and fast deliveries, it is unknown how the soil constructs or the seam of the cricket ball affect the pace, bounce, and deviation of a spinning delivery. A specialised spin bowling machine was used to deliver 276 (139 wrist spin, 137 finger spin) spinning deliveries onto two cricket pitches with contrasting soil properties. The pitches included a bespoke international pitch (BIP; higher sand content at 43.28%) and a common Australian pitch (CAP; lower sand content at 7.44%). Results indicated that the BIP showed significantly slower reflection pace and larger deviation, compared to the CAP. Irrespective of the pitch type, when the seam of the ball impacted the pitch, there was a significantly slower reflection pace and larger deviation. The reflection properties of the BIP resembled that of a "spinning pitch" which can be used as a form of representative practice for conditions similar to those that may be experienced in India. The impact of the seam on the pitch surface significantly altered the reflection of the ball and should be considered in future cricket research.
