چکیده انگلیسی
Based on the course-of-action theory, this study performed a situated analysis of three elite aerial freestyle skiers' activity. Data were collected by observation, videotaping and self-confrontation interviews retrospectively build the athletes' activity. The analysis identified units of action, thought, and feelings and described their relationships during each leap. Comparisons of the different courses of action revealed six components of freestyle skiers' activity: (1) pick up speed in the descent, (2) manage the curve of the tremplin, (3) take-off, (4) manage the exit of the tremplin, (5) perform rotations, and (6) organize the landing. This study revealed the dynamic and situated property of acrobatic activity. As the leap unfolded, the athletes step-by-step enhanced their knowledge of what was occurring and what they would have to do to perform their best and land on their feet. Points of convergence and divergence with other acrobatic performances are discussed.
