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.Contact :

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
