A study published in this week's issue of JAMA Internal Medicine have examined the question of the benefits of walking 10,000 steps and whether this number (actually quite arbitrary) has an impact on the longevity of a selected group of women. Investigators evaluated a cohort of more than 16,000 women, all 72 years old, spread over a 7-day period between 2011 and 2015. Each gave them a portable device to measure the steps of a woman. week to the next. & Nbsp; They then examined the data in stages to see if they correlated with all-cause mortality over the next five to eight years.
The study showed that all-cause mortality decreased in women walking as little as 4,400 steps per day, not women. 10,000 coveted. & nbsp; They also found that once a woman walked more than 7,500 steps a day, walking more than that did not correspond to a decrease in the death rate.
Admittedly, there are several weak points in this study. A potential fault is the precision of the number of steps. Another is that it measures one aspect of the lifestyle (the steps) over a relatively short period of time (one week). But the large number of study subjects and the long-term follow-up (up to eight years) give some weight to these data.
The notion of daily health-related steps is not new. The Amish population, a United community that lives mainly in Pennsylvania (Ohio) and parts of Ontario (Canada), has been the subject of health studies from the point of view of food, genetics, lifestyle and exercise for decades. A 2004 study followed the footsteps of the Amish and found that Amish men walked an average of 18,000 steps per day and Amish women had about 14,000 steps per day. And although the Amish are barely known to nibble kale chips or sip Kombucha, they tend to have extremely low rates of obesity and heart disease, despite a fairly heavy diet and a shortage of Pilates clbad.
Japanese walking clubs in the 1960s and 1970s & nbsp; promoting the use of pedometers, with the goal of 10,000 steps a day. This is a favorable figure in Japanese culture, but it is an arbitrary marker and not based on data indicating a healthy level of activity for adults or children. More recent The data shows that children should walk closer to 13,000 steps & nbsp; every day for ideal activity levels to stay healthy.
The portable technology continues to be more and more portable and more and more technological. The bracelets are elegant, each shopping season is brighter, and there are even rings of portable technology, if the bracelets do not suit you. & Nbsp; Data now extends beyond the markets to include heart rate, sleep patterns, inactivity alarms, and even electrocardiograms. & Nbsp; More than 100 million devices are sold each year worldwide and represent a billion dollars.
Alas, simply following a health indicator does not mean having a healthy lifestyle. In fact, wearing one to lose weight can have the opposite effect. & Nbsp; A 2016 study nearly 500 adults found that adding a portable technology during an intervention aimed at losing weight resulted in less weight loss, no more, over a two-year period. The group with health followers lost half the weight of those who did not. People wearing fitness tracking devices were also less fit, in terms of the degree of daily physical activity.
Precision tracking data is debatable, with an overestimated number of steps up to fifteen percent. But for those who practice minimal physical activity, followers can indeed be motivating. And according to this recent study, walking much less than the 10,000 daily steps sought, especially in its eighth decade, might be enough for the inner tracker to keep the heart turning in the ninth decade and beyond.
