Physical activity plays a pivotal role in maintaining overall health, particularly in young adults who are at a critical juncture in establishing lifelong health habits. This aim of this study was to examine the impact of varying levels of physical activity on selected haematological and biochemical markers among three distinct groups of college students: National Cadet Corps (NCC) cadets, college sports team participants, and sedentary students. A total of 75 male students were selected and divided into these groups, with each group consisting of 25 participants. The study employed a comparative cross-sectional design to analyse blood variables such as haemoglobin levels, red blood cell (RBC) counts, white blood cell (WBC) counts, and total cholesterol levels.

Blood samples were collected in a fasting state and analysed for the mentioned markers. Statistical analysis, including one-way ANOVA and Tukey’s HSD test, revealed significant differences in these variables across the three groups. NCC cadets and sports participants exhibited higher haemoglobin levels and RBC counts, suggesting better oxygen-carrying capacity and overall endurance. Additionally, WBC counts were elevated in these physically active groups, indicating enhanced immune function. Conversely, sedentary students had significantly lower haemoglobin, RBC counts, and WBC counts, along with higher total cholesterol levels, reflecting a greater risk for cardiovascular diseases.

The findings underscore the health benefits of regular physical activity, highlighting its importance in improving haematological and biochemical health markers. This study provides crucial insights for public health strategies aimed at promoting physical activity among college students to mitigate the risks associated with a sedentary lifestyle.
