 note = {The aim of this study is to clarify the characteristics of throwing movements based on the axis of
turning and footwork in a turning phase that is involved with the acceleration of a hammer directly
influencing the performance of hammer throwing. Twenty-four university students （16 males and 8
females） specialized in the hammer throw were asked to throw a hammer with five different length
wires i.e. the standard length, and 10 cm shorter, 5 cm shorter, 5 cm longer and 10 cm longer than
the standard length. After measuring the thrown distances, ratios of them to the thrown distance using
the standard length wire were computed. Finally, their characteristics were investigated using cluster
analysis. As a result, the following three types were grouped: 1） “A type good for adjusting the posture,”
which is excellent to hold the body axis that keeps good posture against the heavy loads. In this type,
as the wire gets long, a tendency for an improved throwing distance was found. 2） “A type good for
footwork,” which was conducted using a short wire and of which the decline in the thrown distance was
small, and was high in adaptability for the turning speed, and 3） “A normal type,” of which performance
is best when using a normal wire, but which cannot skillfully cope with a change in the length of the
wire.},
