HUBUNGAN ANTARA KADAR HEMOGLOBIN DAN KAPASITAS VITAL PARU DENGAN DAYA TAHAN KARDIORESPIRASI SISWA YANG MENGIKUTI EKSTRAKURIKULER BOLABASKET DI SMP NEGERI 1 JETIS KABUPATEN BANTUL

Abstract

Abstrak Penelitian ini dilatarbelakangi oleh kegiatan ekstrakurikuler bolabasket di SMP Negeri 1 Jetis Kabupaten Bantul yang belum ada peningkatan prestasi signifikan. Penelitian ini bertujuan untuk mengetahui hubungan antara kadar hemoglobin dan kapasitas vital paru dengan daya tahan kardiorespirasi siswa puteri yang mengikuti ekstrakurikuler bolabasket di SMP Negeri 1 Jetis Kabupaten Bantul. Subjek penelitian ini adalah siswa putri yang mengikuti ekstrakurikuler bolabasket di SMP Negeri 1 Jetis Kabupaten Bantul berjumlah 20 siswa. Penelitian ini merupakan penelitian korelasional untuk mengetahui ada hubungan yang signifikan antara antara kadar hemoglobin dan kapasitas vital dengan daya tahan kardiorespirasi. Metode yang digunakan adalah survei dengan teknik pengambilan datanya menggunakan instrumen tes dan pengukuran kadar hemoglobin darah, kapasitas vital paru dan multi stage fitness. Teknik analisis data menggunakan uji korelasi product moment dan korelasi ganda dengan taraf signifikansi 0,05 pada SPSS 17,0 for windows. Hasil penelitian menunjukkan bahwa ada hubungan antara kadar hemoglobin dan kapasitas vital paru dengan daya tahan kardiorespirasi siswa yang mengikuti ekstrakurikuler bolabasket di SMP Negeri 1 Jetis Kabupaten Bantul. Hal ini ditunjukkan besaran nilai rx1y=0,581, rx2y= 0,595, Rx1x2y= 0,664 dan nilai signifikansi masing-masing variabel p< 0,05. Kata kunci: hemoglobin, kapasitas vital paru, daya tahan kardiorespirasi RELATIONSHIP BETWEEN CONCENTRATION OF HEMOGLOBIN AND VITAL LUNG CAPACITY WITH STUDENTS CARDIORESPIRATORY RESISTANCE WHO PARTICIPATED IN BASKETBALL EXTRACURRICULAR INSTATE JUNIOR HIGH SCHOOL 1 JETIS. Abstract This research is based on the basketball extracurricular activities in State Junior High School Negeri 1 Jetis Bantul Regency which still has no significant achievement. The aim of this study is to determine the relationship between hemoglobin levels and vital capacity of the lung with cardiorespiratory endurance of female students who were join basketball extracurricular in State Junior High School 1 Jetis Bantul Regency. The subject of this study is 20 female students who participated basketball extracurricular in State Junior High School 1 Jetis Bantul Regency. This study is a correlational study to determine whether there is a significant correlation between the hemoglobin level and vital lung capacity with cardiorespiratory endurance. The method used in this study is survey data retrieval technique which was using test and measurement instruments blood hemoglobin levels, lung vital capacity and multi stage fitness. The data were analyzed using product moment correlation test and multiple correlations with a significance level of 0.05 in SPSS 17.0 for Windows. The result of the study shows that there is a correlation between hemoglobil levels and vital lung capacity with cardiorespiratory endurance of basketball extracurriculars participants in State Junior High School Negeri 1 Jetis Bantul Regency. This demonstrated the amount of value are rx1y=0,581, rx2y= 0,595, Rx1x2y= 0,664 and significance each variables is p< 0,05. Keywords: hemoglobin, vital lung capacity, cardiorespiratory endurance.
