KONTRIBUSI KEKUATAN OTOT PERUT DAN KELENTUKAN TANGAN TERHADAP SERVIS ATAS PADA ATLET BOLAVOLI SMA 1 DARUL IMARAH TAHUN AJARAN 2021/2021

Abstract

The service ability of students who have not been able to perform basic techniques properly and
correctly. Besides that, it is also caused by factors of poor physical condition, such as
abdominal muscle strength and flexibility of the hands of players who are still weak when
serving up. The research formulation includes: (1 ) how is the contribution of abdominal muscle
strength and hand flexibility to upper serve in volleyball athletes at SMA 1 Darul Imarah
Academic Year 2020/2021. This study aims: (1) to determine whether there is a contribution of
abdominal muscle strength and hand flexibility to the upper serve in volleyball athletes at SMA
1 Darul Imarah Academic Year 2020/2021. The approach used in this research is a quantitative
approach and the type of correlation research. The population in this study was 30 people and
30 samples were taken by total sampling. The data were collected through abdominal muscle
strength tests, hand flexibility tests and upper serve tests with battery tests. serve on volleyball
is 0.370 compared to hand flexibility which only has an effect of 0.073. The contribution given
by abdominal muscle strength and flexibility of hands simultaneously to serve on volleyball is
2.42%. The variable that gives a significant contribution to the service on volleyball is the
strength of the abdominal muscles, because the value of tcount > ttable (2.107 > 1.7032) which
indicates that H0 is rejected. While the flexibility of the hand does not provide a significant
contribution because tcount < t table ( 0.3873 > 1.7032). It is recommended for further research
that it is better in the selection of variables, there needs to be an in-depth study so that the
results obtained can provide more benefits and it is better to add other variables that can affect
the top service in volleyball.
