Sport psychologists researchers and practitioners, coaches, sports commentators, sports fans, and athletes acknowledge the importance of mental toughness and flow state in sporting performance. The mental toughness and flow state are utmost pre-requisite of individual and team athletes. The recent sport psychology literature supports the notion that mental toughness and flow state is not a unitary concept and that it has a number of underlying components. Flow is generally viewed as a peak performance state, and there is some support for this assumption. Therefore, a multi-method approach including qualitative techniques would provide more specific information about, and prevent misinterpretation of, flow experiences in competition settings. It is important to understand what flow is and how people experience flow. But with the phenomenal and ever increasing popularity of psychological variables in the past few years, there is a lack of study on this particular discipline, for this purpose that the present study of mental toughness and flow state is proposed and undertaken using the sample from university level male athletes of open and closed skills.
