The Tokyo Olympics in 1964 made history by being the first to be telecast internationally and popular sports, including judo and sumo wrestling, were broadcast in colour. Public interest in the Games also created a lasting legacy which organisations around the world have adopted and keep adopting today.
To paraphrase Neil Armstrong on the Apollo 11 moon landing, that’s 10,000 steps for mankind and one giant step for a healthier society.
Published findings found that the average Japanese person took between 3,500 to 5,000 steps per day. A Japanese research team lead by Dr Yoshiro Hatano capitalised on these findings and the nations interest in sports. The team recognised that if this could be increased to 10,000 steps a day, people would become healthier. And so, Dr Hatano began selling a 10,000-step pedometer known as ‘manpo-kei’ (10,000 step meter) and this arbitrary number quickly grew into the ideal daily number to aim for. Japan’s Ministry of Health still recommends a daily walk of 8,000 to 10,000 steps.
Fifty years later the UK National Obesity Forum, which says the average Briton walks about 3,000 -4,000 steps a day, suggests we should aim for between 7,000 and 10,000. The National Health Service (NHS) is promoting “Walking for Health” as it is simple, free and one of the easiest ways to get more active, lose weight and become healthier. In London, the NHS is working with Transport for London (TfL) to encourage walking as part of your journey to work, walking to the shops, using the stairs instead of the lift, leaving the car behind for short journeys. Both organisations are encouraging people to use apps to track how much and how fast you’ve walked. TfL have produced maps showing walking times between stations to encourage a variety of walks including parks, trails, towpaths and nature reserves. My local favourite is from Paddington, which is Zone One to Warwick Avenue, one stop on the Bakerloo Line but in Zone 2. The walk goes along the canal, past the Robert Browning Island in Little Venice, where the Regent’s canal and Grand Union Canal meet. You save money and have a car free walk.
Most governments’ guidelines and health agencies plus organisations such as the World Health Organisation (WHO), US Centre for Disease Control (CDC), US Surgeon General, American Heat Foundation, US Department of Health and Human Services recommend daily activity of 10,000 steps. A study published in the Journal of The American Medical Association concluded that use of a pedometer (or a tracking device) is associated with significant increase in physical activity and decreases in body mass index and blood pressure.
At Tokyo 2020 we will all be busy urban adventurers and 10,000 steps a day will be easily completed going from one event to another. It will be a fitting tribute to Dr Hatano that so many people will be doing 10,000 steps in his city 50 plus years after he invented the basic metric to good health.
