Did you know that the “10,000 steps per day” injunction comes from a Japanese advertising campaign for a pedometer during the Tokyo Olympics? A team has studied the exact number of steps needed per day to maintain good health and increase life expectancy. It turns out that it depends on the age. You may also be interested
[EN VIDÉO] Interview 3/5: how are nutrition and life expectancy linked? In France, life expectancy is one of the best in the world, but this performance is not only linked to nutrition. Genetics may also be one of the reasons. Béatrice de Reynal, nutritionist, agreed to tell us about it during this interview. The practice of a sports activity improves our state of health The theories established by physics apply within well-defined frameworks.

It also promotes good mental health. Overall, being active improves our life expectancy! The number of steps per day is a good reflection of a person’s physical activity. With today’s phones, it is a measure very easy to implement!While the motto “10,000 steps per day” has the advantage of being easy to remember, it is not always easy to apply it every day.Furthermore, few scientific studies of good quality have been conducted on the subject.An article recently published in the prestigious Lancet looked into the matter.
A meta-analysis on more than 45,000 subjects
The authors carried out a meta-analysis of 15 publications on the link between the number of steps per day and all-cause mortality in individuals over 18 years of age. A meta-analysis is a statistical method that allows the synthesis of data from independent studies. The work brought together 47,471 subjects. Of these, 3,013 died during the study period. The follow-up period was over seven years. The participants were grouped into four groups, each comprising 25% of the participants (quartiles). In each group, the median number of steps was:
For information, the median is the midpoint of a dataset. That is to say that in group 1, there were as many people who walked less than 3,553 steps per day as people who walked more than 3,553 steps per day.
Different results according to age
Statistical analysis of the results showed that the number of steps needed to obtain a protective effect on health and life expectancy was different before and after 60 years.
The ideal would be to walk 6,000 to 8,000 steps per day for those over 60 and 8,000 to 10,000 steps per day for those under 60. Even more interesting, the effect is dose-dependent! The more we walk, the more we increase our life expectancy. On the other hand, for the over 60s for example, from 8,000 steps per day, there is no longer any additional gain in organic matter, nitrogenous matter, etc.
There are different families like:
