| Abstract: | This study outlined the development, implementation, and evaluation of an intervention strategy that was designed to improve the technical skill and performance of an international-level pole vaulter. Intervention, in the form of a prompting and shaping procedure, consisted of breaking a photoelectric beam with the hands at the moment of take-off. The height of the beam was gradually increased until the vaulter reached maximum arm extension at take-off. Increase in arm extension was matched by an increase in bar height clearance. |
