Two coaches and the athletes they train - gymnasts Paul Hall and Louis Smith and swimmers Bill Furniss and Rebecca Adlington - explain how you go about developing a successful coach and athlete relationship. Discuss: the key function of a coach; coach/performer compatibility and how this is attained; how a coach develops a vision for an individual athlete and develops a way of working to achieve that. How important is it for coaches to understand their athletes' personal life? Stresses and pressures.
