Abstract

Background: Sport is a physical activity that increases human body oxygen demand. Hemoglobin has a major role to fulfill the oxygen demand. The body capacity to fulfill the increasing oxygen demand could be seen as cardiorespiratory fitness. Sportsmen have a high cardiorespiratory fitness due to the intensity and frequency of training. This study aimed to explore how hemoglobin concentration affects the cardiorespiratory fitness of adolescence sportsmen. Method: This study used a cross-sectional approach. The sampling started in October – November 2019. Sample of this study were 15-19 years old male badminton and basketball sportsmen at Jakarta and Bogor (n=72). Hemoglobin concentration measured with a digital hemoglobinometer which used an azide-methemoglobin method. VO2max estimated with a beep test. FITNESSGRAM® Performance Standard was used for the classification of cardiorespiratory fitness. All measurement’s ethical issues had been approved. The result of hemoglobin concentration and cardiorespiratory fitness was processed by SPSS program with Spearman and Kruskal-Wallis analysis method. Results: There was a correlation between hemoglobin concentration and cardiorespiratory fitness (p = 0.001, p < 0.05). Spearman analysis showed there was a weak correlation (r = 0.38) between hemoglobin concentration and cardiorespiratory fitness. Kruskal-Wallis analysis showed there was a meaningful mean difference in hemoglobin concentration on cardiorespiratory fitness groups (p = 0.005, p < 0.05). Conclusion: The mean of the hemoglobin concentration on the Healthy Fitness Zone (HFZ) cardiorespiratory group was higher than on the Need Improvement (NI) group and the Need Improvement within Health Risk (NI-HR) group.

Abstract

Background: Cardiorespiratory fitness (CRF) is an important indicator of cardiorespiratory health and a strong predictor of mortality. Several factors affect CRF, including arterial oxygen content (CaO2), which is influenced by hemoglobin (Hb) concentration and oxygen saturation. However, the correlation between CRF and Hb remains inconclusive. This study aimed to explore the correlation between Hb concentration and oxygen saturation post-exercise with CRF, especially in young adults.Methods: A cross-sectional study was conducted in October 2024, involving 68 medical students from a university in Jakarta, Indonesia. Consecutive stratified sampling was applied based on gender. The Global Physical Activity Questionnaire (GPAQ) and the Physical Activity Readiness Questionnaire (PAR-Q+) were used as screening tools. Hb concentration and oxygens saturation were measured using a digital hemoglobinometer and pulse oximetry, while CRF was evaluated using a 20-meter multistage test. Additional measurements included body mass index (BMI), blood pressure, and heart rate. Data were analyzed with correlation and multiple linear regression tests.Results: The most participants were female (57.4%). Normal Hb concentration was found in 80.9% with mean Hb levels of 14.15±1.54 g/dL in males and 12.9±1.37 g/dL in females. CRF correlated positively with Hb concentration (p=0.005; r=1.13), and negatively with oxygen saturation post-exercise (p=0.005; r=-0.4). These correlations were significant in males and not in females.  Conclusion: Hb concentration and oxygen saturation post-exercise significantly correlate with CRF in males, whereas BMI and physical activity play stronger roles in females. Maintaining optimal Hb levels, preventing anemia, and promoting active lifestyles are essential strategies to support CRF, cardiovascular health, and long-term wellness.
