Abstract: INTRODUCTION: Fishing while underwater has been reported to require more energy, but recreational diving is classified as a light exercise. We evaluated the work load associated with scuba diving by monitoring the heart rate of divers using electrocardiograph. MATERIALS AND METHODS: Eight male divers with diving experience ranging from 0.3 (beginner) to 7 years were enrolled in the study. To monitor the heart rate of the divers, the electrocardiograph of each subject was monitored using a Life Scope. Maximum oxygen intake (VO2max) of the subjects were measured using the All-ou test. RESULTS: Before the start of the dive, the average diver's heart rate was 99 bpm, while the beginner's heart rate was 125 bpm. The average heart rate increased to 112 bpm as the divers put on their scuba gear. After entering the water and floating, the average heart rate was 108 bpm, and beginner's heart rate was 141 bpm (32percent of VO2max). The average heart rate during the feet-first descent was 115 bpm, 108 bpm while diving at a depth of 20m, and 115 bpm during the ascent to the surface. The average percent VO2max was 24percent. CONCLUSIONS: These results suggest that the workload for scuba diving is not heavy and that floating at the surface is the most demanding activity for beginner divers.
