Dagens #fsvoversigt:

systematic review and meta-analysis of randomised control trials.

Abstract
OBJECTIVE: To conduct a systematic review and meta-analysis of randomised
control trials that examined the effect of walking on risk factors for
cardiovascular disease.
METHODS: Four electronic databases and reference lists were searched (Jan
1971-June 2012). Two authors identified randomised control trials of
interventions ≥ 4 weeks in duration that included at least one group with
walking as the only treatment and a no-exercise comparator group. Participants
were inactive at baseline. Pooled results were reported as weighted mean
treatment effects and 95% confidence intervals using a random effects model.
RESULTS: 32 articles reported the effects of walking interventions on
cardiovascular disease risk factors. Walking increased aerobic capacity (3.04
mL/kg/min, 95% CI 2.48 to 3.60) and reduced systolic (-3.58 mm Hg, 95% CI -5.19
to -1.97) and diastolic (-1.54 mm Hg, 95% CI -2.83 to -0.26) blood pressure,
waist circumference (-1.51 cm, 95% CI -2.34 to -0.68), weight (-1.37 kg, 95% CI
-1.75 to -1.00), percentage body fat (-1.22%, 95% CI -1.70 to -0.73) and body
mass index (-0.53 kg/m(2), 95% CI -0.72 to -0.35) but failed to alter blood
lipids.
CONCLUSIONS: Walking interventions improve many risk factors for cardiovascular
disease. This underscores the central role of walking in physical activity for
health promotion.
