For generations, swimming has been the exercise recommendation of choice for patients with many maladies. But strangely, during the same time period, very few investigators examined the benefits of any vertical aquatic exercise for the cardiopulmonary compromised patient. In fact, patients with congestive heart failure, myocardial insufficiencies, or peripheral vascular diseases were often warned vehemently against getting in the pool.
In effect, the pool became off-limits for this population. Wrongly so.
1. Swimming and aquatic vertical exercise were inappropriately lumped into the same risk category. Swimming – especially for the novice or marginal swimmer – requires very high oxygen demands and can easily bump a compromised patient into near maximum VO2 levels. Vertical aquatic exercise, on the other hand, has a shallower learning curve. It requires less skill and coordination to execute. More importantly, the effects of hydrostatic pressure on the immersed lower extremities create a pressure gradient which propels blood up to the chest. This results in greater myocardial perfusion and makes for a more efficient cardiac workout.
2. Individuals exercising in water improperly used land-based models for calculating target heart rates. The traditional method for determining exercise intensity (220 - your age x 60%-80%) is grossly inadequate for use in the pool, especially for the cardiopulmonary compromised patient. The hydrostatic pressure gradient allows the heart to expel a larger quantity of blood with each compression. This improved stroke volume allows the heart to beat less frequently for a given cardiac output. Thus, aquatic target heart rate zones should be established at 12-17 beats-per-minute lower than their land-based equivalent.
3. Individuals with low vital capacities were not aware of simple positional changes which would improve respiratory comfort during immersion. The hydrostatic pressure of the water against the chest wall of a respiratory –compromised patient may make breathing difficult. There are three simple options to remedy this situation. Exercise in shallower water. Exercise in a supine position (usually with floats). Or intermittently use this increased resistance as a progressive resistive exercise program for the diaphragm and inter-costal muscles.
4. Physicians equated the temperatures of therapeutic pools with hot-tubs. However, most therapy pools (and all traditional swimming pools) use water which chills the body during quiet immersion. A pool must be heated to 93-94° Fahrenheit in order for an individual at rest to gain heat during immersion. However, if a patient has difficulty “throwing off” heat built up during exercise in water which is near thermoneutral (90-93° Fahrenheit), care should be taken to allow radiation and evaporation to occur. This can be accomplished by keeping the head uncovered, keeping humidity near or below 50%, and allowing rest breaks.
The concept of vertical aerobic exercise in the pool (labeled as hydro-gymnastics) gained exposure in the early 1900s. By the 1950s and 1960s, the age of space exploration did much to stimulate research into the effects of immersed exercise on breathing and circulation. But it wasn’t until the 1990s that therapy and fitness providers brought the same popularity to vertical aquatic exercise as horizontal swimming had enjoyed.
Today, there are dozens of strong, solid studies and many systematic reviews heralding the benefits of aquatic exercise for this population. Take a look and see for yourself.
