Being ‘out of shape’ raises diabetes risk regardless of weight

For adolescents, low cardiorespiratory fitness and poor muscle strength increase their risk for type 2 diabetes later in life, regardless of body weight, according to a study of young men in Sweden.

“Not only were both low aerobic and muscular fitness linked with a higher long-term risk of diabetes, but this was true even among those with normal body mass index,” said lead author of the study Dr. Casey Crump of the Icahn School of Medicine at Mount Sinai in New York City

These risk factors had a synergistic effect. In other words, the combination of low aerobic and muscular fitness increased diabetes risk more than the sum of the two individual risks.

Diabetes risk in women reduced by resistance training

High intensity interval trainingThat’s the finding of an eight year study, published in the journal PLoS Medicine, which tracked the health of nearly 100,000 nurses in the US.

The results show that muscle building exercises, such as lifting weights and doing press-ups, are linked with a lower risk of diabetes.

The reduced diabetes risk seen in the study, was an additional benefit to those also gained from doing aerobic workouts that exercise the heart and lungs.

An important and overlooked consequence of climate change

Global WarmingClimate change has been described as one of the greatest threats to the environment and to human health and a new study published in the August issue of the Journal of Physical Activity & Health looks at the possible consequences to health.

One of the key outcomes of climate change is a rapid increase in global temperatures, resulting in rising sea levels and an increased frequency of acute heatwaves.

The population health risks linked to such temperature changes include increased morbidity and mortality due to infectious disease outbreaks and exposures to air pollution.

Fact or Fiction

HydrationIn an article in the British Journal of Sports Medicine, Dr. Peter Brukner, Human Kinetics’ author of Stress Fractures and clinic director at Olympic Park Sports Medicine Centre in Melbourne, looks at some commonly held core principles that may in fact be myths.

“Let’s start with a couple of quiz questions. Put your hands up if you have given the following pieces of advice to your patients/athletes. (1) Thirst is not a good indicator of hydration. You must drink lots of fluids before, during and after exercise. (2) The optimum diet for weight control, general health and athletic performance consists of low fat, high carbohydrate.

Cycling and walking ‘must become norm’ for short journeys

People should shun the car for all journeys that could be cycled or walked in 15 to 20 minutes according to the UK’s National Institute for Health and Clinical Excellence (NICE).

Regular physical activity is key to achieving and maintaining a healthy lifestyle and can help reduce the risk of heart disease, stroke and type 2 diabetes, as well as being important for good mental health.

However, cycle use is lower in Britain than it is in other European countries, such as the Netherlands, Denmark and France.

School-based programmes could cut diabetes risk

Schools can play an important role in lowering children’s risk of type 2 diabetes according to a new study published in the New England Journal of Medicine.

Researchers found that secondary school students were less likely to be obese and to have other risk factors for diabetes if their school offered healthier food, more vigorous PE lessons and expanded health education.

Anti-oxidants in Diabetes link

antioxidantsAn international team of scientists, led by researchers at Monash University, Victoria, Australia, has found that anti-oxidants commonly touted for their health-promoting benefits, could contribute to the early onset of Type 2 diabetes.

The team, led by Professor Tony Tiganis from the Monash Department of Biochemistry and Molecular Biology, has found that Reactive Oxygen Species (ROS) may play a protective role in the early stages of Type 2 diabetes by enhancing insulin action and that anti-oxidants prevent the beneficial effects of ROS.

Older adults benefit from improved elasticity of arteries after aerobic exercise

Keeping FitJust three months of physical activity provides heart health benefits for older adults with type 2 diabetes by improving the elasticity in their arteries.

This has the effect of reducing risk of heart disease and stroke, Dr. Kenneth Madden told the 2009 Canadian Cardiovascular Congress, co-hosted by the Heart and Stroke Foundation and the Canadian Cardiovascular Society.

Vitamins may undo exercise boost

pillsAntioxidant vitamins can undo some of the most important health benefits of exercise, research has shown.

Taking vitamins C and E after a workout appears to prevent physical exercise improving the body’s energy regulation, a study found and ironically, it is the supplements’ health-boosting properties that appear to be to blame.
