Adolescents who walk to and from school have higher overall physical activity levels throughout the day compared with those who travel by car, bus, or train.

The study, published online by the BMJ today, suggests that how children travel to and from school seems to affect overall physical activity. Understanding these findings is important for promoting healthy school and transport strategies.

Researchers measured moderate to vigorous physical activity among 92 pupils aged 13-14 years, from four schools in the Edinburgh area of Scotland. Pupils were asked to wear accelerometers ( an instrument used to measure vertical movement ) throughout the day and were surveyed about their journey to school.

Pupils were split into three different groups: those who travelled both ways by car, bus, or train; those who walked both ways; and those who walked one way.

Pupils who walked both ways accrued the most minutes of moderate to vigorous physical activity throughout the day, followed by those walking one way. Moderate to vigorous physical activity outside school hours was significantly higher among those pupils who walked both ways than among those using a car, bus, or train.

In all, 87% of pupils using a car, bus, or train, accumulated an average of 60 or more minutes of moderate to vigorous physical activity on weekdays compared with 90% of those who walked one way and 100% of pupils who walked both ways.

Walking to school is associated with higher overall moderate to vigorous physical activity throughout the day compared with travelling by car, bus, or train, say the authors.

Similar results have been reported for 10 year old children, although among 5 year olds, mode of travel to school did not significantly affect overall physical activity, suggesting that walking to school may be more effective for older children.

Reasons for increased physical activity may include differences in appreciation of activity, and walking in the morning may stimulate further activity and social facilitation, they suggest.

Understanding these differences would enhance health promoting school and transportation strategies, they conclude.

About the author:Mike Adams (aka the "Health Ranger") is a best selling author (#1 best selling science book on Amazon.com) and a globally recognized scientific researcher in clean foods. He serves as the founding editor of NaturalNews.com and the lab science director of an internationally accredited (ISO 17025) analytical laboratory known as CWC Labs. There, he was awarded a Certificate of Excellence for achieving extremely high accuracy in the analysis of toxic elements in unknown water samples using ICP-MS instrumentation. Adams is also highly proficient in running liquid chromatography, ion chromatography and mass spectrometry time-of-flight analytical instrumentation.

Adams is a person of color whose ancestors include Africans and Native American Indians. He's also of Native American heritage, which he credits as inspiring his "Health Ranger" passion for protecting life and nature against the destruction caused by chemicals, heavy metals and other forms of pollution.

Adams is the founder and publisher of the open source science journal Natural Science Journal, the author of numerous peer-reviewed science papers published by the journal, and the author of the world's first book that published ICP-MS heavy metals analysis results for foods, dietary supplements, pet food, spices and fast food. The book is entitled Food Forensics and is published by BenBella Books.

In his laboratory research, Adams has made numerous food safety breakthroughs such as revealing rice protein products imported from Asia to be contaminated with toxic heavy metals like lead, cadmium and tungsten. Adams was the first food science researcher to document high levels of tungsten in superfoods. He also discovered over 11 ppm lead in imported mangosteen powder, and led an industry-wide voluntary agreement to limit heavy metals in rice protein products.

In addition to his lab work, Adams is also the (non-paid) executive director of the non-profit Consumer Wellness Center (CWC), an organization that redirects 100% of its donations receipts to grant programs that teach children and women how to grow their own food or vastly improve their nutrition. Through the non-profit CWC, Adams also launched Nutrition Rescue, a program that donates essential vitamins to people in need. Click here to see some of the CWC success stories.

With a background in science and software technology, Adams is the original founder of the email newsletter technology company known as Arial Software. Using his technical experience combined with his love for natural health, Adams developed and deployed the content management system currently driving NaturalNews.com. He also engineered the high-level statistical algorithms that power SCIENCE.naturalnews.com, a massive research resource featuring over 10 million scientific studies.

Adams is well known for his incredibly popular consumer activism video blowing the lid on fake blueberries used throughout the food supply. He has also exposed "strange fibers" found in Chicken McNuggets, fake academic credentials of so-called health "gurus," dangerous "detox" products imported as battery acid and sold for oral consumption, fake acai berry scams, the California raw milk raids, the vaccine research fraud revealed by industry whistleblowers and many other topics.

Adams has also helped defend the rights of home gardeners and protect the medical freedom rights of parents. Adams is widely recognized to have made a remarkable global impact on issues like GMOs, vaccines, nutrition therapies, human consciousness.

In addition to his activism, Adams is an accomplished musician who has released over a dozen popular songs covering a variety of activism topics.
