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.

Ktrain has two modes: 'Setup workout' and 'Do workout'.
The first mode is used to select the machines for your workout and enter the weights and settings for each of the machines selected. The 'Do workout' mode is used during your workout and will display the settings for a machine and then time your set. It shows your current heart rate and elapsed time during the set and optionally will provide a pacing signal to assist you maintain the recommended 4-2-4-2 pace.

It records data from your workout in a FIT file (see ANT+) which can be displayed in one of the companion Garmin CIQ apps (i.e. Garmin Connect Mobile or Garmin Connect using a web browser). It supports English, German, French and Spanish languages depending on the setting on your watch.

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
