Research suggests that psychological characteristics and social behaviors (e.g. cognitive, personal, behavioral and ethical competencies) contribute to the development of coaching effectiveness and as such should not be neglected by strength and conditioning (S&C) coaches. This review examines the current literature on the influence of psychosocial characteristics and behaviors of the S&C coach on elite athlete development. Additionally, this review provides practical suggestions and guidelines to coach developers and coach practitioners to develop such psychosocial behaviors using constructivist learning theories in relation to reflection, stories, mentorships, and internships.
