The science and medicine of cricket: an overview and update

Research into the science and medicine underlying cricket performance and injury has progressed since the First World Congress of Science and Medicine in Cricket in 1999. This review covers material on the physiological and psychological demands of the game and preparation for it, the biomechanics and motor control of cricket skills, the psychology of team dynamics, performance analysis and cricket injuries. Technological aspects of cricket equipment are also covered, where such research could influence injury risk or player performance. Fielding remains the least studied of the skills. Much more research needs to be done before we can gain a full understanding of the scientific aspects of the game. There is a need to address common definitions of injury, along with more research into injury mechanisms. Research on batting needs to bring together motor control and biomechanics more fully. The fitness demands of the game are still poorly understood, along with the mechanisms causing fatigue. Evaluation of the efficacy of intervention strategies needs to continue and to develop. The applications of research need to be communicated more to coaches and players--for example, in team dynamics--so that they can be applied, and tested further, in international matches.     

Self-employed workers: Returns to education and training

An empirical investigation of human capital returns to owners of unincorporated nonfarm businesses is described, and the results are compared with those for a similar cohort of employees. Data are from the older male cohort of the National Longitudinal Survey. A single-equation semi-log regression model is employed throughout. Results show that human capital returns to self-employed workers are basically consistent with results for employees, but some differences emerge. As hypothesized, returns to general training are somewhat larger and returns to specific training somewhat smaller for self-employed workers. The time path of returns associated with job tenure also differs.
