Ten-Year Follow-Up of Physical Activity among Adolescents

16.04.2013
A study from the University of Gothenburg, Sweden, shows that the drop in boys’ physical activity during the teenage years levels off in early adulthood

In 2000, about 1000 children aged 6-14 from southeast Sweden participated in an international study on physical activity, body constitution and physical self-perception.

The new study is a follow-up study on a sample of the 12-year-olds in the original study. The researchers followed and reassessed the group at age 15, 17 and 22. As in the first study, they measured physical activity using a pedometer.

The results indicate a reduction in total daily physical activity from the early teenage years to early adulthood. The boys show a dramatic drop between the ages of 12 and 15. Girls are on average more active than boys at both 17 and 22.

The activity pattern – the question of whether the most active children are also the most active as adults – is maintained only to a low extent. However, those who were deemed insufficiently active at age 12 seemed to maintain their activity pattern to a larger extent as adults.

‘This is a problem. But low-activity children can be identified with simple methods like using a pedometer. They could then be targeted in school and through intervention programmes,’ says Anders Raustorp, Senior Lecturer at the Department of Food and Nutrition, and Sport Science, University of Gothenburg, and one of the researchers behind the new study.

While many previous studies have looked at what happens to adolescents’ exercise habits, this study also explores their overall levels of daily physical activity. Studies including objective measures of physical activity over the course of a whole decade in this age span are extremely rare.

Raustorp has previously published global steps-per-day recommendations for both children (2004 and 2011) and adults (2008). He has also introduced the pedometer in Swedish research and as a useful method in physiotherapy, and has become an authority within pedometer research.

His and his colleagues’ step-per-day recommendations for children and adolescents published in International Journal of Behavioral Nutrition and Physical Activity are in frequent use.

Objective measurements based on validated pedometers and accelerometers offer new opportunities to measure and communicate physical activity as number of steps per day. This simple measure continues to gain respect and popularity among both researchers and practitioners as an acceptable way to assess total daily physical activity.

The study Tracking of pedometer determined physical activity. A 10 years follow-up study from adolescence to adulthood in Sweden was published online in December by Journal of Physical Activity & Health.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
