Abstract


Plyometrics is about a form of burst-of-power trammg with
characteristic usage
of very strong and quick muscle contractions
and also represents isometric, eccentric, and isotonic training
combinations. The training
of plyometrics is with knee-tuck jump
modification and
of side-front-back jump combination models. A
research this article is about is aimed at proving that both practice
models above can improve leg power and that plyometric practice is
able to have great influences on leg power improvement.
The population
of the research study consists of male-athlete
students
of the volleyball school of the Sport Science Faculty, State
University
of Yogyakarta. The sample used consisted of 48
students/athletes selected with an intake technique by means
of
purposive sampling. The trainees were divided into similar three
groups: the first group was treated with the knee-tuck jump
modification, the second group was treated with side-front-back
jump combination, and the third group was given
no specific
treatment
to function as a control group. Before and after the
treatments, a vertical jump test was administered. A normality test
on the data showed that the data distribution was normal and a
homogeneity test on the three groups showed that they were
homogeneous. From an Anova test on two treatments with a control
group, significant differences were found.
The results
of data analysis indicate that plyometric knee-tuck
jump modification and side-front-backjump combination training by
means
of the program for the research study is proven to have
influences on the increase
of leg muscle power of students/athlete of the volleyball school. The side-front-back jump combination
model is more influential than the knee-tuck jump modification
model.
