Abstract
The aim of the study was to examine the effects of high-intensity interval training (HIIT) with high-intensity continuous training (HICT) on increasing hemoglobin levels and oxygen saturation in healthy men. This study used a quasi-experiment with a pre-test-post-test group design. A total of 40 healthy male adolescents, aged 19-22 years, with a body mass index (BMI) of 20-24 kg/m2 and normal blood pressure, were recruited from university students and given HIIT and HICT intervention programs for 30 minutes. Hemoglobin levels were measured using Mission® Hemoglobin Test Strips, while oxygen saturation (SpO₂) and heart rate (HR) were measured using an Oxyone Pulse Oximeter. The mean pre-HIIT and HICT hemoglobin levels were 16.86 ± 1.39 vs 16.34 ± 1.28 g/dL (p = 0.221), and post-intervention were 18.36 ± 0.96 vs 15.41 ± 1.55 g/dL (p = 0.000). SpO₂ pre-values between HIIT and HICT were 96.75 ± 1.37 vs 96.45 ± 1.36 % (p = 0.491), and post-values were 97.85 ± 1.23 vs 96.15 ± 1.35 % (p = 0.000). HR pre-values between HIIT and HICT were 71.40 ± 7.03 vs 71.20 ± 7.98 bpm (p = 0.933), and post-values were 81.25 ± 11.79 vs 97.05 ± 5.54 bpm (p = 0.000). The study concluded that HIIT was effective in increasing hemoglobin and SpO2 levels as an indicator of cardiorespiratory fitness compared to HICT. Furthermore, HIIT was also found to be more effective at speeding up HR recovery.
