Should we all be aiming to get our fitness five-a-day? | BreakingNews.ie

We’ve all heard about five-a-day when it comes to getting enough fruit and veg, but what about when it comes to moving our bodies?

Just five short and easy exercises a day could be the key to safeguarding our future health – including helping prevent certain cancers.

Studies have shown that even small amounts of regular movement can be beneficial. In fact, just three-and-a-half minutes per day of vigorous activity like stair-climbing can reduce overall cancer risk by 17-18 per cent, compared to doing no vigorous activity – research from University of Sydney published last month found.

However, not having enough spare time is often cited as a barrier to exercise. Over half (56 per cent) of adults say having more time, energy and feeling fitter would motivate them to be more physically active, according to a new poll commissioned by the World Cancer Research Fund.

But getting your fitness five-a-day doesn’t have to mean big workouts – it’s micro breaks of movement that you can incorporate into your daily life.

Cost can also a barrier many people experience when it comes to staying active. But ‘exercise snacking’ doesn’t cost a penny – it’s something you can do every day in the comfort of your own home.

“The whole basis is around making exercise easy – don’t feel you have to carve out specific time for it,” says nutritionist and health information and promotion manager at World Cancer Research Fund, Matt Lambert.

“I think that’s really the key, because a lot of people’s barriers when it comes to keeping active is time, because of work and family. Sometimes people don’t realise you can build movement into your day.”

Keen to get your fitness five-a-day and help safeguard your future health? Here are some ideas…

1. Start walking while you’re on the phone

Do you have a call scheduled at work? Lambert says this is a great excuse to get moving. Whether it’s going out for a brisk walk or just pacing in your workspace, moving while you’re taking a call is an easy way to squeeze in some activity.

“It’s something I do all the time, and I go back to work and then think, ‘Actually I am a little bit more energised, I feel so much better’ – then it’s just about building that into someone’s daily life and routine,” says Lambert.

2. Make use to ad breaks while watching TV

There are mini-exercises you can spend a few minutes one while waiting for your favourite programme to come back on. Lambert recommends push-ups using your coffee table, or even standing up and sitting down repeatedly.

“It could be chair squats, it could be two minutes of crunches, or maybe jumping jacks. It’s about giving people options depending on their fitness levels and finding something they’re able to do,” says Lambert.

3. Multi-task while brushing your teeth

It’s a mindless activity that you do twice a day, so why not use that teeth-brushing time to get a mini workout in?

Whether it’s pacing around the bathroom or doing squats on the spot, Lambert says even 20 seconds of movement that raises your heart rate will be beneficial in the long run if done regularly.

“The whole thing when it comes to behaviour change is making those habits sustainable, and something that we do automatically is brushing our teeth at night, so it’s all about us making exercise as easy as possible,” says Lambert.

4. Get moving while making a cup of tea

How many jumping jacks does it take for the kettle to boil? Every bit of movement you can get in the day adds up, even if it’s just for a matter of minutes, and Lambert says that making use of activities you already do on a daily basis could be the key to making it stick.

“Sometimes, people tend to fixate on exercise and physical activity or sport, all about the end goal of maybe changing how they look. But ultimately, what you’re helping to do [by making activity bursts part of your day] is reduce your risk of cancer, and helping you live longer,” adds Lambert.

5. Start a kitchen disco

Pop on your favourite playlist and spend a couple minutes of the day dancing.

“You don’t have to be drenched in sweat, and you can just be on your own,” says Lambert. “Put a song on and dance for a couple of minutes. It’s about making it accessible, easy, friendly, fun, and enjoyable.”

Lambert adds that one of the most important things when it comes to changing your lifestyle is consistently. And remember: “Doing something is always better than doing nothing.”

Exercise Boosts Brain ‘Ripples’ Tied to Learning and Memory

Exercise Boosts Brain ‘Ripples’ Tied to Learning and Memory

Each time you go for a jog, ride your bike, or get active in other ways, you’re giving your brain a boost. A small new study has for the first time directly documented this phenomenon, which the researchers call “ripples” — brief bursts of electrical activity in a part of the brain called the hippocampus.

While exercise is known to improve memory, scientists have mostly studied this effect by using behavioral tests or brain imaging methods like MRIs, says Michelle Voss, PhD, one of the study’s authors, a professor, and the director of the Health, Brain, and Cognitive Lab at the University of Iowa in Iowa City.

But she says these approaches can’t precisely identify where “ripples” originate, particularly in the deep brain structures like the hippocampus, a part of the brain strongly connected to memory and learning, she says.

The current study, published in Brain Communications, recorded electrical activity directly, using surgically implanted (intracranial) electrodes. “This allowed us to observe how exercise changes the brain’s memory circuits in real time,” Dr. Voss says.

20-Minute Bursts of Exercise Increase Brain Ripples

To conduct the study, the researchers recruited 14 participants between ages 17 and 50 with drug-resistant epilepsy. The subjects had already been fitted with intracranial electrodes as part of their preparation for surgical epilepsy treatment.

The participants performed a 5-minute warm-up and then rode a stationary bike for 20 minutes at a pace they could maintain. Researchers recorded their brain activity before and after the biking session.

The electrodes showed an increased rate of so-called sharp-wave ripples from the hippocampus and connections with cortical regions of the brain, which are involved in learning and memory.

“Sharp-wave ripples have long been known from animal studies to play a central role in memory,” Voss says, adding that recent studies using intracranial recordings in humans also support the importance of ripples for human memory.

“Our findings are the first to show that exercise can modulate these ripple signals in the human brain,” she says.

Researchers also observed that larger increases in heart rate during exercise were associated with larger changes in ripple activity in cortical networks, Voss adds.

What’s Already Known About Exercise, Memory, and Learning

“We know that exercise is the number-one thing we can do to enhance our memory and learning,” says Catherine Franssen, PhD, an assistant professor in the School of Life Sciences and Sustainability at Virginia Commonwealth University in Richmond. “Exercise will enhance both our ability to learn new things and our ability to remember previously learned things.”

Movement helps pump oxygenated, nutrient-rich blood to the brain, says Dr. Franssen, who was not involved with the new study: “We’re able to activate those brain cells more effectively and energize them.”

The increased blood flow stimulates the growth of new neurons and enhances the production of brain-derived neurotrophic factor (BDNF), a molecule that strengthens connections between brain cells and supports learning, says the neurologist David Perlmutter, MD, who was not involved with the latest study.

Exercise helps build connections between neurons, which deepens and strengthens brain networks, Franssen says.

Physical activity also improves metabolism, which improves insulin sensitivity, helping blood sugar regulation and giving the brain a “more stable and reliable supply of fuel,” Dr. Perlmutter says.

“This is critically important because the brain is an energy-intensive organ, consuming roughly 20 percent of the body’s energy despite representing only a small fraction of body weight,” he adds.

The Research Has Limitations

Voss says researchers were careful to “exclude signals that contained epileptic activity. However, of course, we can’t statistically control for the accumulated effects of having epilepsy on the brain.”

The exercise-brain ripple patterns observed in the current study also closely match those observed in healthy adults using noninvasive brain imaging, such as MRI, she added.

“That convergence across very different methods is one of the strongest indicators that the effects are not specific to epilepsy, but reflect a more general human brain response to exercise,” Voss said.

Researchers also didn’t directly test memory performance, Voss notes. “While hippocampal ripples are strongly linked to memory processing in decades of neuroscience research, the next step will be to measure how exercise-related changes in ripples relate to memory performance in the same individuals.”

Future studies should also compare exercise with other everyday activities, such as sitting quietly or light movement, to determine how specific these effects are to aerobic exercise at the intensity that was studied, she says.

Satisfy Your Brain’s Exercise Craving

It’s never too early or too late to start exercising for brain health, Franssen says.

People of any age, from grade-school children to people in their nineties, can benefit from increased physical activity, Perlmutter says. “My recommendation is to consider taking advantage of the connection between physical activity and brain health across the entire range of human aging.”

Any type of exercise is great, Franssen says, but especially “repetitive behaviors,” like swimming, jogging, and walking.

“Sometimes we let the hugeness of putting in a huge fitness routine get in our way,” she says. “Having a little exercise snack every so often is also very important to improving cognition.”

Higher Fitness Levels Amplify Brain Benefits After Exercise, Study Finds

Higher Fitness Levels Amplify Brain Benefits After Exercise, Study Finds

Increasing our level of physical fitness leads to a bigger release of brain-boosting proteins following one session of exercise, a new study led by a UCL researcher has found.

The study, published in Brain Research, took a group of inactive unfit participants through a 12-week training programme of cycling three times per week and made them fitter. Researchers found as their fitness increased, so did the amount of brain-derived neurotrophic factor (BDNF) released following exercise, resulting in improved brain function.

Just 15 minutes of moderate to vigorous aerobic exercise releases BDNF, a brain protein which is known to support the formation of new neurons and new synapses (connections between brain cells), and maintains the health of existing neurons. This is the first study to show that for unfit people, just 12 weeks of consistent training can boost the brain’s response to a single 15-minute workout.

The study, led by Dr Flaminia Ronca (UCL Surgery & Interventional Science, and the Institute of Sport, Exercise and Health), involved 30 participants – 23 male and seven female – taking part in the 12-week programme. To assess fitness levels throughout the programme, participants completed VO2max tests every six weeks, which measures the maximum rate of oxygen your body can consume and use during intense exercise.

BDNF levels were measured pre- and post-VO2max testing, alongside a series of cognitive and memory tests, while also measuring changes in brain activity in the prefrontal cortex – where executive functions such as decision-making, emotion regulation, attention and impulsivity are controlled.

By the final week of the trial, results showed that baseline levels of BDNF did not change, but participants did show a larger spike of BDNF following intense exercise, compared to how their brains responded to intense exercise before the 12-week programme. This was linked to improvements in VO2max (aerobic fitness).

Higher overall BDNF levels and stronger exercise-induced increases were also associated with changes in activity across key areas of the prefrontal cortex during attention and inhibition tasks, though not during memory tasks.

Overall, the results showed that increasing physical fitness can enhance the brain’s ability to produce BDNF in response to acute bouts of exercise, which can have a strong positive influence on neural activity.

Lead author Dr Flaminia Ronca said: “We’ve known for a while that exercise is good for our brain, but the mechanisms through which this occurs are still being disentangled. The most exciting finding from our study is that if we become fitter, our brains benefit even more from a single session of exercise, and this can change in only six weeks.”
