Aerobic conditioning
Specific guidelines for aerobic conditioning vary from individual to individual. Moderate exercise on machines is recommended for patients who have problems with gait, or who need constant supervision and data collection (direct from machines). Aquatic-based programs are beneficial for persons who need the buoyancy of water for conditions such as arthritis or joint pain, but it is estimated that in neck-high water, the heart is approximately 25% more efficient, due in part to improved venous return, and the lessened effects of gravity. Walking programs are most often recommended, but outcomes measurement is difficult, unless time, perceived intensity, or calories can be measured. Modified aerobic dance classes (low impact, chair aerobics, swing dance, etc.) are also beneficial to improve capacity and function in a social atmosphere. They may also improve compliance, as participants wish to exercise with friends and acquaintances who also attend classes4,6.
Strength training
The past decade has seen a change of thought as to the application of strength training to cardiac patients. From McKelvie's review in 1990,3 the amount of information about both the safety and efficacy of strength programming grown substantially. Perhaps the most important challenge is the actual prescription and progression of strength training programs for the individual. Although each patient differs in their needs, the table below highlights a typical strength program and progression for cardiac patients in three different stages.
TABLE I: Strength Program
Stage | Exercise | Sets/Reps | Progression | Comments |
Phase II | Movement (basic) | 2 sets 10-15 reps | increase sets to 3-4 as patient improves range of motion. | Supervised - 1-on-1 ECG during exercise |
| | Light dumb bells | 1-2 sets 10-15 reps | increase by 1-2 lbs. each week |
| | Elastic/rubber tubing | 1-2 sets 5-10 reps | work on improving range of motion and technique each session |
Phase II/III | Light dumb bells | 2-3 sets 8-10 reps | increase 2- lbs. each week on the upper body, 5-10 lbs. on lower body | Supervised - 1-on-1 |
| Strength machines Stretching | 1-2 sets 10 reps | improve range of motion and major muscle group strength improve post surgical area and major muscle groups |
Phase III | Strength machines | 2-4 sets 10-8-6 reps | Move from basic exercises to a more progressive format | Unsupervised exercise, or train with a partner |
| Free weights | 2-4 sets 10-8-6, or multiple sets of 10
| Work on perfecting exercise form, strength, and range of motion |
Long term Programming
Success over months (and perhaps years) requires a well thought out plan. Outcomes can only be achieved if a progression is known, and followed as closely as possible. Below highlights a one year progression for a combination program in cardiac rehab for a phase IV patient who is post-op for over a year, and sedentary for the entire time.
