The effect of the addition of resistance training to diet education on apolipoproteins and dietary quality in overweight and obese older adults
Objectives. To examine the additive effect of resistance training (RT) to diet education (DE) on emerging coronary heart disease (CHD) risk factors, apolipoprotein B (apoB) and AI (apoAI) concentrations, and Dietary Approaches to Stop Hypertension (DASH) Diet Index scores in overweight and obese older adults. Design. This is an ancillary study of a randomized clinical trial. Participants and setting. A total of 27 overweight or obese subjects, 11 men and 16 women, mean age 66.6±4.3 years. Intervention took place at the University of Rhode Island, DE only (n=12) and DE plus RT (DERT) (n=15). Intervention. All subjects participated in 30 minutes of DE per week for 10 weeks. Subjects in the DERT group participated in an additional 40 minutes of RT three times per week for 10 weeks. Measurements. Anthropometrics (height, weight, waist circumference, and body composition), clinical (blood pressure), biochemical (lipid profile, apoB, and apoAI concentrations), and diet quality measured by the DASH Diet Index. Results. Differences between groups at post-intervention were seen in triacylglycerols, apoB, and DASH diet index scores. Improvements within the DE group were seen in energy intake, fat free mass, and systolic blood pressure, and within the DERT group in body weight, percent body fat, body mass index, diastolic blood pressure, and oxidized LDL (all p<0.05). Conclusion. This intervention effectively improved CHD risk factors, body composition, and diet quality in overweight and obese older adults. Future research is needed to determine if apos B and AI are superior to lipoprotein cholesterol concentrations in predicting CHD risk.
