Hubungan Kadar Hemoglobin terhadap Nilai VO₂Max pada Atlet KONI Jawa Timur

Latar Belakang: Hemoglobin berperan penting dalam mengangkut oksigen ke jaringan tubuh, yang berpengaruh terhadap kapasitas aerobik seseorang. VO₂Max merupakan indikator utama kebugaran kardiorespirasi dan sering digunakan dalam menilai performa atlet. Tujuan: Mengetahui hubungan antara kadar hemoglobin dan nilai VO₂Max pada atlet KONI Jawa Timur. Metode: Penelitian observasional analitik dengan pendekatan potong lintang ini melibatkan 53 atlet. Kadar hemoglobin diukur melalui pemeriksaan laboratorium darah rutin, sedangkan VO₂Max diestimasi dengan Multistage Fitness Test. Analisis bivariat menggunakan uji Spearman dengan tingkat signifikansi p < 0,05. Hasil: Rerata hemoglobin keseluruhan adalah 14,99 ± 1,42 g/dL, sedangkan rata-rata VO₂Max sebesar 34,4 ± 9,58 mL/kg/menit. Uji korelasi menunjukkan nilai r = -0,009 dengan p = 0,946, yang berarti tidak terdapat hubungan signifikan antara kadar hemoglobin dan VO₂Max. Kesimpulan: Tidak ditemukan hubungan bermakna antara kadar hemoglobin dan VO₂Max pada atlet KONI Jawa Timur. Faktor lain di luar hemoglobin kemungkinan lebih berpengaruh terhadap kapasitas aerobic.

Background: Hemoglobin is essential for oxygen transport, influencing an individual’s aerobic capacity. VO₂Max serves as a key indicator of cardiorespiratory fitness and athletic performance. Objective: To determine the relationship between hemoglobin levels and VO₂Max in athletes of KONI East Java. Methods: This analytical observational study with a cross-sectional approach included 53 athletes. Hemoglobin was measured via blood tests, while VO₂Max was estimated using the Multistage Fitness Test. Spearman correlation was used for bivariate analysis (p < 0.05). Results: The mean hemoglobin level was 14.99 ± 1.42 g/dL, and the average VO₂Max was 34.4 ± 9.58 mL/kg/min. Spearman test showed r = -0.009 with p = 0.946, indicating no significant relationship between hemoglobin and VO₂Max. Conclusion: There was no significant correlation between hemoglobin levels and VO₂Max in KONI East Java athletes. Other factors may have a greater impact on aerobic capacity.
