This chapter provides a directions for the training of mental toughness. Mental Toughness is a term that is commonly used to describe an athlete who when under pressure has demonstrated some form of mentally tough behavior. The environment (home, training and competition) seems to be a main pre-cursor for the development of mental toughness. Meta-analytic data supports the benefits of psychological and psychosocial skills training interventions for sport performance. The mental toughness intervention and traditional groups differed significantly from the control group across several dimensions of mental toughness, resilience and flow at the end of the competitive season. In addition to influencing personality and psychological resources, interventions designed to foster mental toughness would be expected to elicit certain psychophysiological changes which promote mentally tough behaviours.
