Hemoglobin (Hb) adalah zat yang terdapat pada sel darah merah yang sifatnya sangat kuat mengikat oksigen. Selain mengangkut oksigen juga akan menyuplai nutrisi ke jaringan tubuh dan mengangkut zat sebagai hasil dari metabolisme sehingga menghasilkan energi. Penelitian ini bertujuan untuk menganalisis hubungan kadar hemoglobin dengan daya tahan kardiovaskuler, daya daya tahan otot perut dan kekuatan otot lengan. Jenis penelitian ini merupakan penelitian korelasional. Populasi adalah seluruh siswa pendidikan pertama tamtama TNI AD gelombang II Kodam IM TA. 2021 berjumlah 405 siswa. Sampel penelitian ditentukan melalui probability sampling dengan teknik simple random sampling sehingga diperoleh sampel sebanyak 30 siswa. Teknik pengumpulan data terdiri dari: (1) Kadar hemoglobin di ukur melalui uji laboraturium menggunakan Swelab Lumi 5 diff, (2) Daya tahan kardiovaskuler diukur dengan tes lari 12 menit (cooper test), (3) Daya tahan otot perut diukur dengan tes Sit-Up, dan (4) Kekuatan otot lengan diukur dengan tes hand grip dynamometer. Teknik analisis data menggunakan analisis korelasi sederhana dan korelasi ganda pada taraf signifikansi 0,05 dengan SPSS 21. Berdasarkan hasil penelitian dan analisis data menunjukkan bahwa: (1) Terdapat hubungan yang positif dan signifikan antara kadar hemoglobin dengan daya tahan kardiovaskuler (rxy1 = 0.865), kadar hemoglobin memberi kontribusi sebesar 74.82% terhadap daya tahan kardiovaskuler, (2) Terdapat hubungan yang positif dan signifikan antara kadar hemoglobin dengan daya tahan otot perut (rxy2 = 0.427), kadar hemoglobin memberi kontribusi sebesar 18.23% terhadap daya tahan otot perut, (3) Terdapat hubungan yang positif dan signifikan antara kadar hemoglobin dengan kekuatan otot lengan (rxy3 = 0.401), kadar hemoglobin memberi kontribusi sebesar 16.08% terhadap kekuatan otot lengan, dan (4) Terdapat hubungan yang positif dan signifikan secara bersam-sama antara kadar hemoglobin dengan daya tahan kardiovaskuler, daya tahan otot perut, dan kekuatan otot lengan (Rxy1y2y3 = 0.887), kadar hemoglobin memberi kontribusi sebesar 78.68% terhadap daya tahan kardiovaskuler, daya tahan otot perut, dan kekuatan otot lengan. Kesimpulan dari hasil penelitian menunjukkan bahwa terdapat hubungan yang positif dan signifikan antara kadar hemoglobin dengan daya tahan kardiovaskuler, daya tahan otot perut, dan kekuatan otot lengan.

Kata Kunci: Kadar Hemoglobin, daya tahan kardiovaskuler, daya tahan otot perut, dan kekuatan otot lengan.

CORRELATIONAL ANALYSIS OF HEMOGLOBIN LEVELS WITH CARDIOVASCULAR ENDURANCE, POWER STRENGTHEN ABDOMINAL MUSCLES, AND ARM MUSCLES IN THE FIRST EDUCATION STUDENTS TNI AD WAVE II KODAM IM 2021 SCHOOL YEAR Abstrak (Peka Aswan) Hemoglobin (Hb) is a substance found in red blood cells which is very strong in binding oxygen. In addition to transporting oxygen, it will also supply nutrients to body tissues and transport substances as a result of metabolism to produce energy. This study aims to analyze the relationship between hemoglobin levels and cardiovascular endurance, abdominal muscle endurance and arm muscle strength. This type of research is a correlational research. The population is all the first education students enlisted in the TNI AD wave II Kodam IM 2021 school year totaling 405 students. The research sample was determined through probability sampling with a simple random sampling technique so that a sample of 30 students was obtained. The data collection techniques consisted of: (1) Hemoglobin levels were measured through a laboratory test using the Swelab Lumi 5 diff, (2) Cardiovascular endurance was measured by a 12-minute running test (cooper test), (3) Abdominal muscle endurance was measured by the Sit-Up test, and (4) Arm muscle strength was measured by hand grip dynamometer test. The data analysis technique used simple correlation analysis and multiple correlation at a significance level of 0.05 with SPSS 21. Based on the results of research and data analysis, it was shown that: (1) There was a positive and significant relationship between hemoglobin levels and cardiovascular endurance (rxy1 = 0.865), hemoglobin levels contributed 74.82% to cardiovascular endurance, (2) There was a positive and significant relationship between hemoglobin levels and abdominal muscle endurance (rxy2 = 0.427), hemoglobin levels contributed 18.23% to abdominal muscle endurance, (3) There is a positive and significant relationship between hemoglobin levels and arm muscle strength (rxy3 = 0.401), hemoglobin levels contribute 16.08% to arm muscle strength, and (4) There is a jointly positive and significant relationship between hemoglobin levels with cardiovascular endurance, abdominal muscle endurance, and arm muscle strength (Rxy1y2y3 = 0.88 7), hemoglobin levels contributed 78.68% to cardiovascular endurance, abdominal muscle endurance, and arm muscle strength. The conclusion from the results showed that there was a positive and significant relationship between hemoglobin levels and cardiovascular endurance, abdominal muscle endurance, and arm muscle strength. Keywords: Hemoglobin level, cardiovascular endurance, abdominal muscle endurance, and arm muscle strength.
