Optimisation of the upper body motion for production of the bat-head speed in baseball batting
Published 2020“…Performance optimisation was able to achieve a targeted increase in bat-head speed (35.6 m/s to 40.0 m/s) through greater barrel-side shoulder abduction, knob-side elbow flexion, and torso right lateral flexion around ball impact resulted in the bat accelerating in the hitting direction. …”

Wind turbines and bat mortality: interactions of bat echolocation pulses with moving turbine rotor blades.
Published 2009“…This phenomenon is widespread and has received enough attention to warrant investigation into how and why these collisions occur. In this paper we investigate the acoustic interaction of bats with wind turbines, in particular the interpretation of reflected sound pulses (echolocation) used by bats to navigate. …”

The relationships between impact location and post-impact ball speed, bat torsion, and ball direction in cricket batting
Published 2017“…A ‘sweet region’ on the bat face was identified whereby impacts within 2 cm of the sweetspot in the medio-lateral direction, and 4.5 cm in the longitudinal direction, caused reductions in ball speed of less than 6% from the optimal value, and deviations in ball direction of less than 10° from the intended target. …”

The effect of mass distribution on cricket bat playing properties

It is likely that the first bat was an unfashioned branch from a tree and was used to defend against a suitably round stone in the games from which cricket evolved. …”

The interaction of bats (Microchiroptera) with wind turbines: bioacoustic and other investigations
Published 2011“…The main contributions of this thesis are (1) the formulation and application of a novel equation to rate turbine rotors in terms of bat detectability, identifying that features such as rotor angular velocity, number of blades, blade width and bat species all influence the likelihood of rotor detection; (2) passive and active ultrasonic measurements from turbine rotors in order to assess the nature of acoustic bat interaction with turning blades, showing that frequency and amplitude information in returned echoes can vary significantly, echoes may be attractive to bats as mimicry of echoes returned from flying insects, and that some turbines do not emit ultrasonic noise detectable to all bat species; (3) assessment of the Doppler shift profiles generated by moving blades in order to investigate the changing nature of frequency information returned to an echolocating bat, concluding that blades turning under low wind speed conditions may not be detectable by some bat species; (4) Monte Carlo simulation of bat-like rotor sampling to account for the temporally short nature of reflected echoes, with the result that some bat species may not be able to achieve enough echoes to accurately interpret blade movement in the short approach time-window; (5) the creation and utilisation of artificial bat-like pulses for lab-based experimental work and (6) the investigation of insect attraction to turbine paint colours to determine the potential abundance of bat prey around turbine installations, finding that existing turbine colours are significantly attractive to insect species. …”

R2 values for the goodness of fit of the ball and bat curves averaged 0.99 ± 0.04 and 1.00 ± 0.00 with root mean square errors of 7.5 ± 2.6 and 0.8 ± 0.2 mm, respectively. …”

The effects of different delivery methods on the movement kinematics of elite cricket batsmen in repeated front foot drives
Published 2014“…Results showed significant differences in speed and ball release-to-impact time between the three delivery methods, thus questioning the validity of the bowling machine and Sidearm™ in the way they are currently used as true representations of batting against a real life bowler. Findings from the timing and kinematics of the subjects’ movements suggest a different technical response is also exhibited when facing the different delivery methods; for example batters were found to initiate movement earlier and have a lower maximum bat speed against the bowling machine, but initiate and complete their front foot stride earlier as well as moving their COM further forward in the Sidearm™ trials. © 2014 The Authors. …”

We investigated whether acute cold (7 ± 3°C) exposure (1, 10, or 100 h duration) affected protein oxidation and proteasome activity, when compared to warm controls (22 ± 3°C), in a small mammal model, the short-tailed field vole Microtus agrestis. …”

Strength and conditioning for cricket fielding: A narrative review

This is achieved through 1) collecting a batted ball and returning it to the wicketkeeper to prevent runs from being scored, 2) dismissing a batter by catching a batted ball, 3) running a batter out by throwing the ball to strike the stumps, or 4) preventing a batted ball from hitting the boundary. …”
