Influence Of Haemoglobin Concentration On Physical Fitness And Performance: A Comparative Study

Abstract

The present study examines the influence of haemoglobin concentration on physical fitness and performance among trained and untrained individuals. Haemoglobin plays a central role in oxygen transport, which directly affects aerobic metabolism, endurance, and muscular performance. A total of 60 male participants were examined and these were divided into two groups based on haemoglobin levels: Group X₁ (>12 gm/100 ml) and Group X₂ (<12 gm/100 ml). Various physiological and performance tests were carried out on these participants. These included basal pulse rate, post-exercise pulse rate, grip strength, persistence time, and 50-meter dash performance. Statistical analysis was carried out using mean, standard deviation, and t-test which revealed significant differences between groups. The results demonstrated that individuals with higher haemoglobin levels exhibited superior cardiovascular efficiency, faster recovery rates, enhanced muscular strength, and better speed performance. The findings of the study highlight the significance of maintaining optimal haemoglobin levels for improved physical fitness and athletic performance. The study contributes to understanding the physiological role of haemoglobin and suggests nutritional and training strategies to enhance performance.
