Why does physical activity during childhood matter?

What parents, teachers, and lawmakers need to know about physical activity, brain health, cognition, and scholastic achievement

2014-12-02
(Press-News.org) Over the past thirty years, physical activity among children has declined markedly. The public health implications of this decline include a growing prevalence of obesity and chronic diseases such as diabetes and hypertension. A new issue of Monographs of the Society for Research in Child Development expands the focus to ask whether physical activity is also related to children's brain and cognitive development and achievement in school. Scholarly articles published by over 20 researchers in Monographs, titled "The Relation of Childhood Physical Activity to Brain Health, Cognition and Scholastic Achievement" indicate that while physical activity in schools has diminished in part because of a growing emphasis on student performance and academic testing, decreased physical activity is actually related to decreased academic performance.

Approximately 55.5 million children are enrolled in pre-kindergarten - 12th grade in the United States in a given academic year. According to research presented in Monographs, while there is variation across states and schools, overall, opportunities to engage in physical activity have diminished. Current U.S. Department of Health and Human Services guidelines call for children to have a minimum of 60 minutes of intermittent physical activity per day. However, in 2012, according to the Centers for Disease Control and Prevention, only 30 percent of children attended a school in which they were offered physical education daily. The majority of students do not engage in any form of planned physical activity during the school week.

Yet physically active children tend to outperform their inactive peers in the classroom and on tests of achievement. The research presented in the monograph helps to make clear why. When compared to their less fit peers, those who engage in more physical activity have larger brain volumes in the basal ganglia and hippocampus, areas associated with cognitive control and memory. Cognitive control refers to the control of thought, action, behavior, and decision-making.

Physically active children also have increased concentration and enhanced attention spans when compared to their less active peers. The authors find that fitness is related to the ability to inhibit attention to competing stimuli during a task, an ability that can help children stay focused and persevere to complete an assignment. The findings on attention encompass children with special needs as well as typically developing children. The authors also report on physical activity as a non-pharmaceutical intervention for children with attention-deficit/hyperactivity disorder and children with autism spectrum disorders, with positive results.

According to Dr. Charles Hillman, professor of kinesiology and community health at the University of Illinois at Urbana-Champaign and lead author on this issue of Monographs, "these results point to the important potential of approaches focusing on physical activity for strengthening children's brain health and educational attainment. It is important for state governments and school administrators to consider this evidence and promote physical activity in the school setting, which is where children spend much of their time."

Hillman also notes that the findings in the monograph come not only from studies looking at variation in physical activity and fitness level as they occur spontaneously among children, but also from studies in which children are randomly assigned to physical activity interventions or to continue their ongoing activity levels. This helps to assure that the links between physical activity, brain development and achievement are actually caused by the differences in activity rather than reflecting the characteristics of the children who choose to be more or less physically active.

Atmospheric carbon dioxide used for energy storage products

Atmospheric carbon dioxide used for energy storage products
2014-12-02
CORVALLIS, Ore. - Chemists and engineers at Oregon State University have discovered a fascinating new way to take some of the atmospheric carbon dioxide that's causing the greenhouse effect and use it to make an advanced, high-value material for use in energy storage products. This innovation in nanotechnology won't soak up enough carbon to solve global warming, researchers say. However, it will provide an environmentally friendly, low-cost way to make nanoporous graphene for use in "supercapacitors" - devices that can store energy and release it rapidly. Such devices ...

Intermittent fasting even with the occasional cheat day may help combat obesity

2014-12-02
New research in mice suggests that restricting access to food to 8-12 hours rather than allowing constant access to food may help prevent and even reverse obesity and type 2 diabetes. The results of two studies publishing online December 2 in the Cell Press journal Cell Metabolism suggest that this time-restricted eating affects the balance of bacteria found in the gut. Researchers also found the occasional "cheat days" on weekends did not undo the benefits of time-restricted eating in mice. Previously, investigators led by Dr. Satchidananda Panda of the Salk Institute ...

A new study by researchers at the Salk Institute cautions against an extended period of snacking, suggesting instead that confining caloric consumption ...

Vitamin supplement successfully prevents noise-induced hearing loss

2014-12-02
Researchers from Weill Cornell Medical College and the Gladstone Institutes have found a way to prevent noise-induced hearing loss in a mouse using a simple chemical compound that is a precursor to vitamin B3. This discovery has important implications not only for preventing hearing loss, but also potentially for treating some aging-related conditions that are linked to the same protein. Published today in Cell Metabolism, the researchers used the chemical nicotinamide riboside (NR) to protect the nerves that innervate the cochlea. The cochlea transmits sound information ...
