|Abstract: ||Objective. The purpose of this review was to perform a meta-analysis on walking intervention studies in order to quantify the magnitude and
direction of walking-induced changes that may alter selected cardiovascular risk factors.
Method. Twenty-four randomised controlled trials of walking were assessed for quality on a three-point scale. Data from these studies were
pooled and treatment effects (TEs) were calculated for six traditional cardiovascular risk variables: body weight, body mass index (BMI),
percentage body fat, aerobic fitness (VO2 max in ml kg−1 min−1) and resting systolic and diastolic blood pressure. Weighted TEs were analysed
using a random effects model with weights obtained using the inverse of the individual TE variances. Random effects models were used to
investigate the influence of both study quality and exercise volume (<150 vs. ≥150 min week−1).
Results. Random effects modelling showed that walking interventions increased VO2 max and decreased body weight, BMI, percent body fat
and resting diastolic blood pressure in previously sedentary adults (p<0.05 for all).
Conclusion. The results of this study provide evidence that healthy but sedentary individuals who take up a programme of regular brisk
walking improves several known risk factors for cardiovascular disease.|
