Relationship between Hemoglobin Levels and Maximum Oxygen Uptake in Healthy People

 

Background : Cardiorespiratory endurance is the ability of the heart and lungs and blood vessels to function optimally under conditions of rest and exercise to take in oxygen and distribute it to active tissues for use in the body's metabolic processes. Maximum oxygen uptake (VO_{2 max}) is a very objective physiological parameter to measure cardiorespiratory endurance. Oxygen absorbed by the blood in the lungs must be transported to the tissues so that it can be used by the cells. Oxygen in the blood exists in two forms, namely physically dissolved, and chemically bound to Hemoglobin (Hb).  

Research methods : This research is descriptive analytic, because in addition to assessing Hb and VO levels_{2 max} in healthy people, this study also assessed the relationship between the two variables with statistical tests. The basis of this research is cross-sectional where this research is conducted in a certain period, and the sample is only measured once. The research subjects were taken from 50 healthy volunteers with an age range of 20-35 years based on the PAR-Q criteria questionnaire, with inclusion criteria for men, 20-35 years old, fulfilling PAR-Q criteria, and willing to participate in this study . Data analysis using the Pearson correlation test. Data processing was carried out using the SPSS version 15 program. 

Research Results: the number of samples of this study were 50 people. The average age of the subjects who took part in this study was 22,56 years (SD 3,118). The average body weight of the subjects who participated in this study was 63,31 kg (SD 11,07069). The subject's average Hb was 14,066 g% (SD 0.9793), the subject's minimum Hb was 12 g% and the subject's maximum Hb was 16,8 g%. VO average_{2 max} subject was 47,2456 ml/kg/min. (SD 9,75489), subject's minimum V2max was 21,70 ml/kg/min and maximum VO_{2 max} subject was 72,86 ml/kg/min. The relationship between Hb levels and VO_{2 max} from the Pearson correlation test, sig 0,368 (p>0,05) was obtained which showed that there was no significant correlation between Hb levels and VO_{2 max}. The Pearson correlation value of 0,130 (between 0,00-0,199) indicates a positive correlation with very weak correlation strength.

Conclusion : There is no significant relationship between Hb levels and VO_{2 max} in healthy people with an age range of 20-35 years according to the criteria Physical Activity Readiness Questionnaire (PAR-Q) of Canadian Society for Exercise Physiology.
