  Purpose

The purpose of this study was to investigate the effects of an 8 week program of walking for 45 minutes, twice a week, on fitness, body composition , blood pressure and blood markers of cardiovascular risk. We hypothesised that this 90 minutes of walking per week would result in measurable increases in fitness and reductions in body fat, resting blood pressure and improved blood lipid profiles.

Estimated Enrollment: 40
Study Start Date: May 2002
Estimated Study Completion Date: January 2003
Detailed Description:

Current physical activity guidelines suggest that every adult should accumulate 30 minutes or more of moderate intensity physical activity on most days of the week. However, compliance with these guidelines requires considerable commitment in terms of time spent exercising per week (> 150 minutes) and this may deter individuals from starting an exercise programme. Accordingly, randomised controlled trials are needed to evaluate the effects of smaller volumes of exercise on health.

37 civil servants (24 women) aged 41.5 + 9.3 years, were randomly assigned to either two 45 minute walks per week (walking group) or no training (control group). Aerobic fitness, body composition, blood pressure (BP), CRP and lipoprotein variables were measured at baseline and following 8 weeks. Steps counts were measured at baseline and during weeks 4 and 8 of the intervention
