There are different coaching styles that are appropriate with different types of athletes. The factors that influence coaching style include the type of sport, gender, age and level of the athletes. Coaches also use different styles between training sessions and competitive matches. Different behaviour analysis systems have been proposed, including the Arizona State University Observation Instrument (ASUOI), which can be used with a single variable or two variables. Using a limited number of variables and combining behaviour classes can improve reliability. However, some coaches may want more detailed information when reflecting on their behaviour. Therefore, other more complex systems use as many as seven variables (Harries-Jenkins and Hughes, 1995). There is a trade-off between reliability and detail of coach behaviour analysis systems. In scientific research, simpler instruments such as the ASUOI have been used due to the levels of reliability achieved. The more complex systems are preferred in coach education and reflective practice.
