Abstract
Many studies have examined the relationship between regular physical activity and the risk of metabolic disorders. However, few studies have focused on the specific associations between these metabolic disorders and muscular strengthening activity (MSA) patterns. PURPOSE: To compare the odds specific to having each metabolic syndrome (MetS) component among individuals reporting engaging in a level of MSA that would meet the current government guideline of two or more days per week to those not meeting the current recommendation for MSA. METHODS: Study sample (N=5,618) included adults, 20 years and older that participated in the 1999-2004 National Health and Nutrition Examination Survey. Cut-points for MetS criteria were derived from the American Heart Association/ National Heart, Lung, and Blood Institute definition. The aggregate of data on weight lifting, push-ups, and sit-ups was utilized to establish the patterns of MSA. Participants reporting >2 days per week of MSA were coded as meeting the recommendation. RESULTS: Following adjustment for age, gender, race, education, income, smoking, alcohol intake, family history of diabetes and cardiovascular disease, and leisure-time physical activity, participants reporting engaging in a level of MSA to meet the current government guidelines were found to be 28% (OR 0.70; 95% CI 0.62, 0.83) less likely to have dyslipidemia, 29% less likely to have impaired fasting glucose (OR 0.71; 95% CI 0.54, 0.93), and 43% less likely to have an augmented waist circumference compared to those who reported engaging in MSA <2 days per week. No protection was found for hypertension among participants meeting the MSA recommendation. CONCLUSION: Engaging in >2 days per week of MSA as part of an overall physical activity regimen may be prudent in preserving metabolic health.
