KTrain is a Garmin watch app which supports doing Kieser training workouts in a Kieser gym. Note it does not require any additional hardware but this web-site provides more detailed documentation about how to use the app and also enables users to create an account on this web-site, after paying an establishment fee, which enables additional functionality in the app - see registered user section below.

Questionnaires are frequently used in order to get some feedback about how people feel about issues. However care must be taken in the design of the questions and also in the way the responses are taken and analysed. This section will deal with some of those issues starting with some consequences of the way the responses are recorded and the impact on the results.

Cricket implications from modelling the physics of the flight and bounce of cricket balls

These articles are based on the results of a mathematical model I have developed of the aerodynamics of a cricket ball's flight and the dynamics of its bounce (e.g. contact with the pitch).

• Basic aerodynamic forces in cricket
• Drag forces on the ball
• New ball swing
