Your Child’s Fitness Needs A Small Amount of Physical Activity

The Daily Mile was founded in February 2012 by Elaine Wyllie, the then headteacher of St Ninians Primary School in Stirling, to improve the fitness of her pupils.

Motivating school children to take a 15-minute break from class to do physical activity may boost their health and fitness levels, a new study suggests.

The study examined the effectiveness of the popular Daily Mile initiative – which involves children taking a 15-minute break from class to do physical activity.

The findings, published in the journal BMC Medicine, indicate that The Daily Mile can help combat global problems such as low physical activity, high sedentary behaviour, declining fitness levels and high levels of obesity.

“Our research observed positive changes in children who participated in The Daily Mile intervention, compared to our control school where the scheme was not introduced,” said one of the study authors Colin Moran from the University of Stirling in Britain.

The Daily Mile was founded in February 2012 by Elaine Wyllie, the then headteacher of St Ninians Primary School in Stirling, to improve the fitness of her pupils.

Children are encouraged to run, jog or walk around their school grounds during a 15-minute break from class, which is in addition to normal intervals and physical education lessons.

The study involved 391 pupils, aged between four and 12. Each child underwent an initial assessment and then a follow-up later in the academic year.

Between times, one school implemented The Daily Mile, while pupils at the other — known as the control school — followed their usual curriculum.

Children wore accelerometers to record their average daily minutes of moderate to vigorous intensity physical activity (MVPA) and average daily sedentary behaviour.

They also had skinfold measurements taken to check body fat, and were assessed on their performance at a multistage fitness test (known as a bleep test or shuttle run), where they ran between cones 20 metres apart between bleeps.

The team witnessed significant improvements in the intervention school, relative to the control school, the researcher said.

“We observed a relative increase of 9.1 minutes per day in terms of MPVA and a relative decrease of 18.2 minutes per day in sedentary time,” said study co-author Naomi Brooks from the University of Stirling. (IANS)

Why Exercise on Empty Stomach May be Better for Your Health

This is the first study to show that feeding prior to acute exercise affects post-exercise adipose tissue gene expression

If you have been wondering whether it is better to eat or fast before a workout, researchers now have an answer. A new study has found that exercise on empty stomach is better for your health in the long term.

The study analysed effects of eating versus fasting on gene expression in adipose (fat) tissue in response to exercise.

After eating, adipose tissue “is busy responding to the meal and a bout of exercise at this time will not stimulate the same (beneficial) changes in adipose tissue”, explained corresponding author of the study Dylan Thompson from University of Bath in Britain.

“This means that exercise in a fasted state might provoke more favourable changes in adipose tissue, and this could be beneficial for health in the long term,” Thompson added.

“We propose that feeding is likely to blunt long-term adipose tissue adaptation to regular exercise,” the researchers noted in the study published in the American Journal of Physiology — Endocrinology and Metabolism.

The study participants were a group of overweight males who walked for 60 minutes at 60 per cent maximum oxygen consumption on an empty stomach and, on another occasion, two hours after consuming a high-calorie carbohydrate-rich breakfast.

The research team took multiple blood samples after eating or fasting and after exercising.

The researchers also collected fat tissue samples immediately before and one hour after walking.

Gene expression in the adipose tissue differed significantly in the two trials.

The expression of two genes, PDK4 and HSL, increased when the men fasted and exercised and decreased when they ate before exercising.

The rise in PDK4 likely indicates that stored fat was used to fuel metabolism during exercise instead of carbohydrates from the recent meal.

HSL typically increases when adipose tissue uses stored energy to support increased activity, such as during exercise, Thompson said.

These results reinforce the view that “adipose tissue often faces competing challenges,” Thompson wrote.

“This is the first study to show that feeding prior to acute exercise affects post-exercise adipose tissue gene expression,” the study said. (Bollywood Country)
