Scientists compared 3- and 90-minute workouts. The result may surprise you (opens the original)
Read excerpt
For the new study, the researchers had 19 healthy young men visit a lab and either ride a stationary bicycle at a relatively moderate pace for 90 minutes or do all-out sprint intervals. A new study found that three minutes of intense exercise floods our blood with molecules linked to better health. Three minutes of intense exercise may have more beneficial impacts on our physiology and health than 90 minutes of more moderate exertion. That idea could sound far-fetched. But in a groundbreaking ne
The muscle ability you lose fastest with age - and how to preserve it (opens the original)
Read excerpt
Muscle power can be rebuilt at any age. Photo / 123rf It’s never too late to start building muscle power, a leading exercise researcher says. You may be losing power right now, at least in your muscles. That’s because our muscles begin shedding power as we age, a process that typically begins in our 40s and accelerates in later decades. Many of us may not realise we have muscular power to lose, though. “It’s not a metric that’s discussed much, and it should be,” said Brad Schoenfeld, 64, a profe
10 minutes of super-slow running can benefit your brain and mood (opens the original)
Read excerpt
A study has found that running needn’t be strenuous or prolonged to alter how well we think and feel. Photo / 123rf Research suggests a run can feel surprisingly easy and still benefit your thinking skills. Are you, like me, a slow, plodding runner? Congratulations. You may be doing your brain a favour, a new study finds. In the study, 10 minutes of super-slow jogging, at a pace barely exceeding walking speeds, almost immediately changed people’s brain activity, improved their thinking skills an
Here’s how workplace activity may affect dementia risk (opens the original)
Read excerpt
A new study found that physically demanding jobs may be linked to a risk for dementia. Photo / 123rf Exercise outside of work has a different impact on the body than physical activity on the job. Exercise is one of the healthiest things we can do for ourselves and our brains. Most science shows that even a few minutes a day of physical activity generally contribute to lower risks for dementia as we age. But the context may matter. A study published online last week found that physically demandin
3 minutes of this activity may cut the risk of 13 cancers, study finds (opens the original)
Read excerpt
The research offers a new look at how simply sitting less and moving more may affect cancer risk. To reduce your risks for at least 13 types of cancer, jog up and down the nearest steps for three minutes or stand up from your desk or couch for 30. Either strategy might help drop your risks of certain cancers by as much as 7%, according to a new study of how the ways we move – and don’t move – during the day affect our chances of malignancies. The study, published in July in BMC Medicine, is one
