Exercise before school may reduce ADHD symptoms in kids

Exercise before school may reduce ADHD symptoms in kids
2014-09-09
(Press-News.org) EAST LANSING, Mich. – Paying attention all day in school as a kid isn't easy, especially for those who are at a higher risk of ADHD, or attention deficit hyperactivity disorder.

A new study from Michigan State University and University of Vermont researchers shows that offering daily, before-school, aerobic activities to younger, at-risk children could help in reducing the symptoms of ADHD in the classroom and at home. Signs can include inattentiveness, moodiness and difficulty getting along with others.

The study can be found in the Journal of Abnormal Child Psychology.

"Early studies suggest that physical activity can have a positive effect on children who suffer from ADHD," said Alan Smith, chairperson of MSU's Department of Kinesiology, who conducted the research along with lead author Betsy Hoza, a psychologist from the University of Vermont.

Previous MSU research has shown improved brain function and better math and reading skills in elementary students who were exposed to a bout of physical activity. Yet, it's not as widely known how consistent exercise might improve the broad range of symptoms and impairments associated with the disorder.

Over a 12-week period, Smith and Hoza studied about 200 early elementary school students ranging from kindergarten to second grade that either exhibited signs of ADHD or didn't. During the trial, students were randomly selected to participate in a group that completed moderate to vigorous physical activity each day before school, or a group that completed more sedentary classroom-type activities.

"Although our findings indicated that all participants showed improvements, children with ADHD risk receiving exercise benefited across a broader range of outcomes than those receiving the sedentary activities," Smith said.

Smith indicated that further studies are needed to better understand the frequency and amount of physical activity that can provide benefits to children and added that the effects of exercise may be different based on a child's age.

"Despite the number of remaining questions, physical activity appears to be a promising intervention method for ADHD with well-known benefits to health overall," he said. "This gives schools one more good reason to incorporate physical activity into the school day."

INFORMATION: Michigan State University has been working to advance the common good in uncommon ways for more than 150 years. One of the top research universities in the world, MSU focuses its vast resources on creating solutions to some of the world's most pressing challenges, while providing life-changing opportunities to a diverse and inclusive academic community through more than 200 programs of study in 17 degree-granting colleges.

Scientists discover hazardous waste-eating bacteria

2014-09-09
Tiny single-cell organisms discovered living underground could help with the problem of nuclear waste disposal, say researchers involved in a study at The University of Manchester. Although bacteria with waste-eating properties have been discovered in relatively pristine soils before, this is the first time that microbes that can survive in the very harsh conditions expected in radioactive waste disposal sites have been found. The findings are published in the ISME (Multidisciplinary Journal of Microbial Ecology) Journal. The disposal of our nuclear waste is very challenging, ...

Estrogen receptor expression may help explain why more males have autism

Estrogen receptor expression may help explain why more males have autism
2014-09-09
AUGUSTA, Ga. – The same sex hormone that helps protect females from stroke may also reduce their risk of autism, scientists say. In the first look at a potential role of the female sex hormone in autism, researchers at the Medical College of Georgia at Georgia Regents University have found expression of estrogen receptor beta – which enables estrogen's potent brain protection – is significantly decreased in autistic brains. The receptor also plays a role in locomotion as well as behavior, including anxiety, depression, memory, and learning. "If you ask any psychiatrist ...

Phosphorus a promising semiconductor

2014-09-09
Defects damage the ideal properties of many two-dimensional materials, like carbon-based graphene. Phosphorus just shrugs. That makes it a promising candidate for nano-electronic applications that require stable properties, according to new research by Rice University theoretical physicist Boris Yakobson and his colleagues. In a paper in the American Chemical Society journal Nano Letters, the Rice team analyzed the properties of elemental bonds between semiconducting phosphorus atoms in 2-D sheets. Two-dimensional phosphorus is not theoretical; it was recently created ...

A system that facilitates malware identification in smartphones
2014-09-09
Malware is a type of malicious program whose general aim is to profit economically by carrying out actions without the user's consent, such as stealing personal information or committing economic fraud. We can find it "in any type of device ranging from traditional cell phones to today's smartphones, and even in our washing machine," explained one of the researchers, Guillermo Suarez de Tangil, from the Computer Science Department at UC3M. With the massive sales of smartphones in recent years (more than personal computers in all of their history), malware developers ...

Testing the fossil record

Testing the fossil record
2014-09-09
Palaeontologists have developed methods to try to identify and correct for bias and incompleteness in the fossil record. A new study, published on 4 September 2014 in the journal Nature Communications, suggests that some of these correction methods may actually be misleading. The work is led by Dr Alex Dunhill (University of Leeds, formerly at the Universities of Bath and Bristol), together with Hannisdal (University of Bergen) and Professor Michael Benton (University of Bristol). Back to the origin of animals "The Earth keeps changing. Life keeps evolving. And there ...

How age alters our immune response to bereavement

2014-09-09
Young people have a more robust immune response to the loss of a loved one, according to new research from the University of Birmingham, providing insight into how different generations cope with loss. The study, published in the journal Immunity and Ageing, shows how the balance of our stress hormones during grief changes as we age – meaning elderly people are more likely to have reduced immune function and, as a result, suffer from infections. It is the first research to compare different generations and display the relationship between stress hormones and immune ...

Biologists try to dig endangered pupfish out of its hole

Biologists try to dig endangered pupfish out of its hole
2014-09-09
Berkeley — Scientists estimate that fewer than 100 Devils Hole pupfish remain in their Mojave Desert home, but a conservation biologist at the University of California, Berkeley, is giving important guidance in the efforts to rescue them by establishing a captive breeding program. Considered the world's rarest fish, with one of the smallest geographic ranges of any wild vertebrate, the tiny pupfish (Cyprinodon diabolis) – about one-inch long as an adult – neared extinction in spring 2013 when populations dropped to an all-time low of 35 observable pupfish. While more ...

Tracing water channels in cell surface receptors

2014-09-09
G protein-coupled receptors (GPCRs) are the largest class of cell surface receptors in our cells, involved in signal transmission across the cell membrane. One of the biggest questions is how a signal recognized at the extracellular side of a GPCR induces a sequence of conformational changes in the protein and finally evokes an intracellular response. EPFL scientists have now used computer modeling to reveal in molecular detail the structural transitions that happen inside GPCRs during the signal transduction process. They discovered that a central step in the trans-membrane ...

Shift in Arabia sea plankton may threaten fisheries

Shift in Arabia sea plankton may threaten fisheries
2014-09-09
A growing "dead zone" in the middle of the Arabian Sea has allowed plankton uniquely suited to low-oxygen water to take over the base of the food chain. Their rise to dominance over the last decade could be disastrous for the predator fish that sustain 120 million people living on the sea's edge. Scientists at Columbia University's Lamont-Doherty Earth Observatory and their colleagues are the first to document the rapid rise of green Noctiluca scintillans, an unusual dinoflagellate that eats other plankton and draws energy from the sun via microscopic algae living within ...
