Little is known about the nutritional status of heart failure patients and the potential synergistic effects between nutritional intake and exercise. This small, randomized trial examined the effects of a 3-month exercise program on body composition and nutritional intake in 31 men (17 exercisers; 14 controls), aged 30-76 years (mean, 56 years) with stable class II-III heart failure. Baseline and 3-month evaluations included body mass index, body fat mass by triceps skinfold thickness, dietary intake by food frequency questionnaire, and the 6-minute walk test. Exercise consisted of walking 3 d/wk and resistance exercises 2 d/wk for 40-60 minutes. Dietary recommendations were consistent with the American Heart Association/American College of Cardiology heart failure guidelines. Exercisers decreased body weight (p=0.001), body mass index (p=0.0001), and triceps skinfold thickness (p=0.03) and improved 6-minute walk test (p=0.01) compared with controls. Exercisers also demonstrated trends toward decreased total caloric and cholesterol intake and a three-fold higher carbohydrate, fiber, and beta carotene intake vs. controls. In this study population, protein, fiber, and magnesium intake were below recommended daily allowance. After exercise, body mass index was reduced, accompanied by dietary modifications including greater intake of foods with higher moisture content. Further study is needed to investigate the interaction among diet, exercise, and weight. |
