Abstract

CONTEXT: The increasing prevalence of obesity is a major public health concern. Physical activity may promote weight and body fat loss. OBJECTIVE: To examine the effects of exercise on total and intra-abdominal body fat overall and by level of exercise. DESIGN: Randomized controlled trial conducted from 1997 to 2001. SETTING AND PARTICIPANTS: A total of 173 sedentary, overweight (body mass index > or =24.0 and >33% body fat), postmenopausal women aged 50 to 75 years who were living in the Seattle, Wash, area. INTERVENTION: Participants were randomly assigned to an intervention consisting of exercise facility and home-based moderate-intensity exercise (n = 87) or a stretching control group (n = 86). MAIN OUTCOME MEASURE: Changes in body weight and waist and hip circumferences at 3 and 12 months; total body, intra-abdominal, and subcutaneous abdominal fat at 12 months. RESULTS: Twelve-month data were available for 168 women. Women in the exercise group participated in moderate-intensity sports/recreational activity for a mean (SD) of 3.5 (1.2) d/wk for 176 (91) min/wk. Walking was the most frequently reported activity. Exercisers showed statistically significant differences from controls in baseline to 12-month changes in body weight (-1.4 kg; 95% confidence interval [CI], -2.5 to -0.3 kg), total body fat (-1.0%; 95% CI, -1.6% to -0.4%), intra-abdominal fat (-8.6 g/cm2; 95% CI, -17.8 to 0.9 g/cm2), and subcutaneous abdominal fat (-28.8 g/cm2); 95% CI, -47.5 to -10.0 g/cm2). A significant dose response for greater body fat loss was observed with increasing duration of exercise. CONCLUSIONS: Regular exercise such as brisk walking results in reduced body weight and body fat among overweight and obese postmenopausal women.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In sedentary, overweight, postmenopausal women, a 12-month moderate-intensity exercise intervention produced a greater percentage loss in visceral adipose tissue than in body weight, and visceral adipose tissue loss was exercise dose-dependent.

    “Likewise, a greater percentage loss in VAT percentage than in body weight occurred after 12 months in a moderate-intensity exercise intervention study of sedentary, overweight, postmenopausal women. VAT loss was exercise dose-dependent (253).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
