Abstract

PURPOSE:

To evaluate the effects of walking (W) and walking plus resistance training (WRT) on cardiovascular disease (CVD) risk factorsin inactive, middle-aged (49.0±5.5 years) African-American (AA) women (BMI: 34.7±6.4kg.m).

METHODS:

Body composition, blood pressure, high-density lipoprotein cholesterol (HDL), triglycerides (TG), glycosylated hemoglobin (HbA1c), C-reactive protein (CRP), and fibrinogen were measured before and after a 12-week exercise intervention.Subjects were randomly assigned to one of two training groups. W (n=25) was instructed to increase daily pedometer-measured walking to ≥10,000 steps.day, while WRT (n=19) was given the same walking prescription plus supervised resistance training two days.week. A two-way repeated measures ANOVA with an intention-to-treat analysis was performed to examine changes between groups. Significance was accepted at p≤0.05.

RESULTS:

Both groups significantly (p<0.001) increased walking (W: 5,453±2,119 to 6,845±2,279; WRT: 4,823±1,758 to 6,859±2,012steps·day). WRT significantly (p<0.001) increased both upper (100±15 to 113±18 kg) and lower (102±20 to 116±25 kg) body strength compared to W. WRT significantly decreased waist circumference (94.8±12.3 to 92.9±12.0 cm; p=0.021) and total fat mass (42.6±11.1 to 41.8±10.8 kg; p=0.036) compared to W. WRT also significantly decreasedpre- to post-intervention body fat (45.8±6.2 to 45.3±6.2%; p=0.018), HbA1c(5.9±1.2 to 5.6±1.0%; p=0.028), and mean glucose calculated from HbA1c (122±39 to 114±32 mg/dL; p=0.028), while W showed no changes. Blood pressure, HDL, TG, and CRP were not affected by either intervention.

CONCLUSION:

Although both interventions increased steps.day, WRT was more effective in improving several body composition measures and glucose control in 12 weeks. WRTmay be an important addition to a lifestyle intervention aiming to facilitate reductions in CVD risk factors in overweight and obese AA women.
