This study aimed to determine the heart rate and amount of physical activity of two differently skilled athletes while they were competing in amateur radio direction finding (ARDF). Heart rate and GPS data were measured in two athletes during a regional ARDF championship in Japan. Physical activity was estimated using GPS data and altitude derived from a map projection software. Results revealed that compared with the novice, the skilled athlete finished more quickly, covered a shorter distance, and experienced almost no stagnant phases (resting periods). The average heart rate for both athletes exceeded >160 bpm, which is of the same intensity as that found with high-level aerobic training. Additionally, heart rate variations, similar to those observed during intermittent training, were observed in both athletes. Finally, the energy expenditures during the competition greatly exceeded the recommended healthy exercise levels. In conclusion, despite the difference in the skill levels of the athletes, the measured heart rates and estimated physical activity during ARDF were extremely high. However, the difference in skill sets resulted in differences in the total distance covered, total time spent, and movement patterns.
