Twelve weeks of water-based circuit training exercise improves fitness, body fat and leg strength in people with stable coronary heart disease: a randomised trial.

In people with stable coronary heart disease, what are the effects of water-based circuit training exercise on aerobic capacity, strength and body composition? How do these effects compare with those of gym-based exercise? Parallel group, randomised controlled trial with concealed allocation and intention-to-treat analysis. Fifty-two participants with stable coronary heart disease. Twelve weeks of: three 1-hour sessions per week of moderate-intensity water-based circuit training exercise with alternating aerobic and resistance stations (WEX); three 1-hour sessions per week of moderate-intensity gym-based circuit training exercise (GEX); or continuing usual activities (control). Aerobic capacity (VO Forty-five participants completed the study (WEX n = 15, GEX n = 18, control n = 12). Both training groups significantly improved VO WEX was well tolerated and improved aerobic capacity, leg strength and body fat to a similar degree as GEX in people with coronary heart disease. These findings suggest that WEX is an effective exercise training alternative to GEX for people with coronary heart disease. ANZCTR12616000102471.
