Method: Participants were 79 women …

Relationship Between Counter Movement Jump Performance And Extraversion Level, David James Cornell

Introduction: Sport psychology literature has demonstrated a relationship between personality and physical ability and athletic performance. In general, individuals who exhibit a greater degree of extraversion display a greater physical ability and athletic performance than individuals who exhibit a lower degree of extraversion. The physiology literature has also demonstrated relationships between extraversion level and movement time and electrophysiological mechanisms (i.e., muscle activity) during a fine movement task. However to date, no study has investigated if these physiological relationships manifest themselves during a gross movement task. If a relationship exists, it may provide mechanistic reasoning behind the previously observed relationships between …
