PENGARUH LATIHAN PLIOMETRIK MODIFlKASI TERHADAP POWER OTOT TUNGKAI PADA OLAHRAGA BOLAVOLI
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 teston 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 controlgroup, 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.
