 note = {This study aimed to clarify the characteristics of the ways of throwing by classifying javelin
throwers based on records performed under various conditions with a focus on the run-up phase to the
preparation phase in javelin throws. Sixteen university male javelin throwers were asked to perform four
kinds of throwing: a standing throw without a run-up; a one-cross-step throw; and a three-cross-throw.
After computing the ratios of the measured performance mentioned above with their best records in the
season, the classification was conducted using cluster analysis. As a result, the following three types
were obtained: 1）“An upper-body dominated type,” which is dominated by power in the body stem and
upper limbs and of which performance from a cross-step phase is equivalent to approximately 90% of the
best record in the season; 2）“A type in proportion to the running-up speed,” which gradually increases
from standing-throwing to the best record in the season and of which throwing performance improves
in proportion to the running-up speed; and 3）“A lower-body dominated type” which is excellent in the
Stretch-Shortening Cycle（SSC）of lower limbs and for which excellent throwing performance can be
expected at a speed above a certain level with the increasing rate from three-cross-step throwing to the
best record in the season at approximately 30%. As the “upper-body dominated type” and “lower-body
dominated type” out of these classified types tend to have a high athletic level, it was suggested that it
is needed to possess physical fitness such as SSC in the upper or lower limbs to obtain a certain athletic
level.},
