OBJECTIVE: To assess the acute cardiovascular response to aquatic exercise in
patients with osteoarthritis. DESIGN: Blood pressure (BP) and heart rate (HR)
were measured in 13 female patients with osteoarthritis (63.3 +/- 8.4 yrs) during
aquatic walking for 40 mins.
A double product (DP) value was calculated by
multiplying systolic BP by HR to evaluate the workload of the heart. RESULTS: BP
and DP increased transiently with a decrease in HR after water immersion. Aquatic
walking induced increases in BP, DP, and HR. Furthermore, BP and DP increased
sharply with an increase in HR on leaving the water.
The mean maximum increases
in systolic BP and DP during each process were 23.5 +/- 18.2 mm Hg and 2931.1 +/-
2758.5 mm Hg/min when entering the water, 36.5 +/- 16.5 mm Hg and 4557.2 +/-
3435.1 mm Hg/min during aquatic walking, and 38.5 +/- 18.9 mm Hg and 5132.3 +/-
3228.8 mm Hg/min on leaving the water. CONCLUSIONS:
Water immersion, aquatic
walking, and the process of leaving the water induced marked increases in BP in
patients with osteoarthritis.
