Walking groups have good adherence and can reduce blood pressure, risk of depression, cholesterol and BMI, according to a review published in the British Journal of Sports Medicine.

The Hanson & Jones systematic review and meta-analysis took information from electronic databases, clinical trial registers, grey literature and reference lists, reviewing 42 studies which involved 1,843 people.

Reviewers found significant reductions in mean systolic and diastolic blood pressure, resting heart rate, body fat, body mass index, total cholesterol and depression scores.

They also found significant mean increases in lung capacity and speed.

High levels of adherence were reported and virtually no side effects.

These findings add fuel to the debate of whether health clubs should be reaching out beyond their four walls and organising community walking groups, which could engage those who would not normally venture into a gym and offer an entry level activity.

Speaking in Health Club Management’s April issue, Tom Williams, managing director of parkrun UK, said health clubs must offer experiences which are social and become a habit stating that; “health clubs have a wonderful opportunity to get outside their four walls with running and walking clubs"
