  • This study compared the heart rate (HR) and blood lactate (BL) responses in young healthy women performing the same routine of aerobics exercise in 3 different conditions: on land, in shallow water (0.8 m), and in deep water (1.4 m). The average age and body mass index (BMI) of the group were 27.4 years and 22.6 kg·m-2, respectively. The highest HR and BL values were reached during land aerobics (median HR values were 138.0 and 161.5 b·min-1, and lactate values were 3.10 and 5.65 mmol·L-1 at slow and at faster pace, respectively). These parameters were progressively reduced going from shallow water (121.5 and 154.0 b·min-1, 1.75 and 3.15 mmol·L-1) to deep water (97.5 and 113.5 b·min-1, 1.70 and 1.75 mmol·L-1). The HR measured as percentage of maximum HR varied from 48.43% to 77.53% depending on the water depth and the pace. These data indicate that exercise in water significantly reduces HR and BL production compared with the same exercise performed on land.
