The Faculty of Sport and Health Sciences at the University of Jyväskylä has examined how changes in the daily step count are related to changes in the body mass index (BMI), causing us to get fat.
During the four-year follow-up period, especially women increased their daily step count significantly. Approximately 25% of the research participants increased their step count with more than 2,000 steps, whereas approximately 19% decreased their step count during the follow-up. The follow-up examined BMI and body fat.
The participants were grouped into increasers, decreasers and maintainers according to the total of their steps. The changes in the groups’ BMI were compared to the changes in their step count, and the comparison of the step counts was proportioned to the time the step counter had been kept on.
During the research period, there was growth in both the women’s and the men’s BMI. Almost half of the participants maintained the amount of their daily aerobic steps at the same level and approximately one-fourth increased their daily step count with over 1,000 steps during the research period.
The test participants whose total step count grew by more than 2,000 steps during the follow-up period, maintained their BMI at the same level throughout the years. In contrast, BMI increased for those whose step count stayed at the same level or decreased.
– The trend in physical activity looks good. International studies have shown that physical activity generally decreases along with age, but here it increased, Professor Mirja Hirvensalo states. Even though step counts in general look good, it should be noted that the amount of passive people who take less than 5,000 steps per day did not change significantly during the research period.
The researchers remind everyone about the significance of incidental activity and how it relates to body fat.
– The steps accumulate on many instances during the day, if you give it a chance. One does not necessarily need to go for a walk every day to increase the daily step count. Instead, attention should be paid to choices in everyday life. Does every trip need to be made by car or could some of them be done by foot, or could the stairs be taken instead of the elevator, Postdoctoral Researcher Kasper Salin reminds us.
The Cardiovascular Risk in Young Finns Study has been monitoring over 3,000 Finns regularly from 1980 onwards. One part of the study considers physical activity, and during the last two measurings it was monitored with step counters. During the four-year follow-up period, the step count data and the required background variables were gathered from a total of 1,033 participants. During the follow-up period, the examinees were from 34 to 49 years of age. The recommended daily step count for adults is 10,000 steps.
