Increasing the number of steps you take per day is associated with a lower risk of death and cardiovascular disease, regardless of how much time you spend sedentary.
Regardless of how much sedentary time you have left, each additional step you take up to around 10,000 steps per day reduces your risk of death and cardiovascular disease (CVD), the online British Journal of Sports Medicine says. A large population-based study published reports.
Some previous studies have shown that higher steps per day are associated with lower levels of death and CVD, while higher levels of sedentary behavior are associated with an increased risk of CVD and death. There are also studies that show that it is related. However, none of these studies investigated whether high levels of physical activity may offset or reduce the high risk of death and cardiovascular disease associated with sedentary time.
To address this, the authors of this new study led by the University of Sydney/Charles Perkins Center looked at 72,174 people (mean age 61 years, 58 women) enrolled in the UK Biobank Study (a major biomedical database). %) data was accessed. An accelerometer device will be worn on her wrist for 7 days to measure physical activity.
Accelerometer data was used to estimate daily steps and sedentary behavior, or time spent sitting or lying down during waking hours.
Participants’ median daily step count was 6,222 steps/day, and 2,200 steps/day (minimum 5% of daily steps among all participants) was associated with an increase in step count’s impact on mortality and CVD events. was adopted as a reference point for evaluating.
The median time spent sitting was 10.6 hours/day, so study participants who sat for more than 10.5 hours per day were considered sedentary, whereas those who sat for less than 10.5 hours per day Participants were expected to spend less time sedentary.
Over a mean follow-up of 6.9 years, there were 1,633 deaths and 6,190 CVD events.
After considering other potentially influencing factors, the authors found that the optimal daily step count for combating sedentary time is between 9,000 and 10,000 steps/day, which They calculated a 39% reduction in the risk of death and a 21% reduction in the risk of developing CVD.
In both cases, 50% of the benefits were achieved between 4000 and 4500 steps per day.
This is an observational study and cannot prove cause and effect. Additionally, although the large sample size and long follow-up reduced the risk of bias, the authors acknowledge that other unmeasured factors may have influenced the results. The researchers added that step counts and sedentary time were obtained at a single point in time, which could also lead to bias.
Nevertheless, they concluded that “taking more than 2,200 steps per day with both short and long periods of sedentary time was associated with a lower risk of mortality and developing CVD.” Masu.
“A step count of 9000 to 10,000 steps/day optimally reduced the risk of mortality and developing CVD in sedentary participants. The minimum threshold associated with substantially lower mortality and CVD risk was 4000 to 10,000 steps/day. It was 4,500 steps/day.”
They further state that “our future results have relevant implications that can be used to strengthen public health messages and inform first-generation guidelines for device-based physical activity and sedentary behavior.” We will provide you with our findings, which may include specific recommendations for daily walking,” it added.
