LET WALKING BE YOUR NEW YEAR’S RESOLUTION
WHAT nicer way could there be to work off the excesses of Christmas than a walk? A growing body of evidence suggests that it’s one of the best forms of exercise for both body and brain.
So if you’re looking for a New Year’s resolution you can stick to, here the experts reveal what walking could do for you…
WE’RE BUILT FOR IT
Physiotherapist Sammy Margo says bodies hate the jolty, aggressive movement you get with jogging. “Walking allows your heart to pump in a rhythmical way, meaning your circulation is at its most efficient.”
It has an almost zero injury rate, compared with running, which causes injuries in up to 80 percent of people. “That’s because when you walk you’re carrying three to four times your body weight; with running it’s six to eight times,” says Margo.
Studies have shown that men who walk more than 2km a day reduce their risk of heart disease by half. And one study found that men with hypertension saw their blood pressure reduced for four hours after just a 30-minute walk.
IT BEATS BACK PAIN
Lower back pain is often put down to the fact we were meant to be on all fours. But osteopath Clive Lathey says the opposite is true.
“If you look at the pelvis, the sacroiliac joint in the lower back and the S-shaped curve of the spine, they are designed for shockabsorbing vertical force.
“We’re well adapted to walking. What we’re not adapted to is spending lots of time sitting down in cars and at computers – that tightens and weakens the muscles in the back.”
Sammy Margo agrees: “Walking nourishes and ‘juices’ the discs and joints of the back.”
IT’S GREAT FOR YOUR BEHIND…
“Walking is incredible for your bottom, as long as you do it with a long stride,” says fitness expert Lucy Wyndham Read.
“You can test this by standing up and taking a big step back – you’ll feel all the muscles in the bottom and backs of the legs are being used. That’s what happens when you’re walking. Now stand up and lift one leg up as if you’re jogging – you’ll notice it’s not the same.”
…AND YOUR BRAIN
A US study last year showed a daily stroll may increase the size of your brain.
Researchers at the University of Illinois studied 120 volunteers aged 50 to 80 over of a year. Half were assigned to start walking 40 minutes a day, three times a week, while the others were told to do stretching and toning exercises.
After 12 months, brain scans showed the walking group had an average 2 percent growth in the hippocampus – the brain’s memory centre. The stretching group’s hippocampuses shrank 1 percent.
Arthur Kramer, professor of psychology and neuroscience and co-author of the study, believes cardiovascular activity such as walking boosts blood flow to the brain, triggering new neurons to grow, giving the brain a “cushion” that protects from dementia.
Commenting on the findings, Dr Lynn Millar of the American College of Sports Medicine, says walk- ing is good for the brain because it makes it multitask. “When we walk we integrate visual input, auditory input and input coming from joints and muscles.”
IT WILL CHEER YOU UP
Like all exercise, walking releases the “feel-good” hormones endorphin, serotonin and dopamine – but its gentle pace is thought to be one of the best for depression.
“Short bouts of moderate exercise make people feel more activated and positive than during vigorous exercise, which is stressful,” says Adrian Taylor, professor of exercise and health psychology at the University of Exeter.
“Walking gets you away from stresses of work or home,” adds Ken Fox, professor of health sciences at Bristol University.
Michael Depledge, professor of environment and human health at the University of Essex, agrees that the pace of walking, as opposed to running, allows the brain to fully take in your surroundings, which seems to boost mental wellbeing.
“We’re not sure why, but walking outdoors is better for you than doing the same amount of walking around a shopping centre.
“Being in contact with nature seems to provide mental restoration – we think that things you experience through the senses such as the eyes and the nose have an effect on the brain.”
WALK BEFORE, NOT AFTER, A HEAVY MEAL
Many like to “walk off ” a heavy meal – but studies show a stroll before eating is even better because it reduces damage done by the highfat foods you’re about to eat.
Glasgow University research found a 90-minute walk before dinner lowered fat levels in the blood by 25 percent both before and after the meal and improved the function of the inner walls of blood vessels, meaning they were better defended from the build-up of harmful fatty deposits.
The researchers suggested that exercise improves the way the body metabolises food.
“If you are going to overeat at lunchtime or dinner, it would be worth considering going for a good long walk first as this at least can undo some of the damage,” says Professor Peter Weissberg of the British Heart Foundation, which was involved with the research.
Walking before a meal may also mean you’re less likely to overeat, suggests recent research from the University of Campinas, Brazil. It found a stroll before eating helps restore the sensitivity of brain cells involved in the control of fullness.
COUNT YOUR STEPS
Experts recommend walking 10 000 steps a day to maintain a healthy heart and keep weight in check. Use a pedometer to count your quota.
Some people clock up that much without realising. “If you walk 20 minutes to work in the morning, or to the station, that’s 5 000 already,” says Lucy Wyndham-read. “Do the same at night and you’ve hit your target.”
IT BURNS THE CALORIES
“Brisk walking can burn just as many calories as jogging,” says Lucy Wyndham-read.
To burn fat you should walk at 140 steps a minute. Twenty minutes will burn 180 to 220 calories.
She says you can make your walk even more of a workout by carrying a backpack with a bottle of water inside, or by walking on sand or through long grass.
If you’re not a brisk walker, try a longer hike. “If you’re not walking at speed, after 45 minutes your body starts to use fat cells for extra fuel,” she says. – Daily Mail
