The doctoral research paper titled "Relationship between Core Body Temperature, Seasonal Variations & Match Intensity among Footballers" investigated the physiological interplay between core body temperature (CBT), seasonal environmental changes, and varying levels of match intensity among competitive football players. Recognizing the thermoregulatory challenges posed by high-intensity sports, the study aimed to provide empirical evidence on how environmental heat stress and physical exertion collectively influence internal temperature regulation, performance, and potential health risks.
A total of 60 male footballers aged 18–30 years, with consistent professional or semi-professional playing backgrounds, were observed across three major climatic seasons: summer, monsoon, and winter. CBT was measured using ingestible telemetric capsules that provided real-time data during match play. Match intensity was evaluated using GPS-based tracking systems and heart rate monitors, capturing metrics such as total distance covered, sprint count, and average heart rate. Simultaneously, ambient temperature, humidity, and Wet Bulb Globe Temperature (WBGT) were recorded to contextualize external heat exposure.
The results showed a significant rise in CBT during high-intensity matches, especially in summer, where post-match CBT often exceeded 39°C. Players with optimal hydration demonstrated a smaller CBT increase, highlighting the protective role of fluid balance. A strong positive correlation was found between match intensity parameters and CBT elevation.
This research underscores the importance of season-specific thermal management strategies, tailored hydration protocols, and real-time physiological monitoring to optimize player safety, performance, and recovery. It contributes valuable knowledge for sports scientists, coaches, and medical staff working in high-demand, climate-sensitive sporting environments.
