Background:
Providing flexible models and a variety of exercise options are fundamental to supporting long-term exercise participation for patients with heart failure (HF). The aim of this pilot study was to determine the feasibility and efficacy of aquatic exercise training during a maintenance phase for a clinical heart failure population.
Methods:
In this 2 x 2 crossover design trial, individuals who had previously completed HF rehabilitation were randomised into either a land-based or aquatic training program once per week for six weeks, after which time they changed to the alternate exercise training protocol for an additional six weeks. Six-minute walk test (6MWT), grip strength, walk speed, and measures of balance were compared for the two training protocols.
Results:
Fifty-one participants (43 males, mean age 69.2 yrs) contributed data for the analysis. Both groups maintained function during the follow-up period, however improvements in 6MWT were greater in the land-based training group (95% CI: 0.7, 22.5; p=0.038), by a mean difference of 10.8 metres. No significant difference was observed for other parameters when the two training protocols were compared.
Conclusion:
Attending an aquatic exercise program once per week is feasible for patients with stable HF and may provide a suitable option to maintain functional performance in select patients.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
