(Press-News.org) Nordic walking enables heart failure patients to exercise more intensely than walking without poles.
The research was presented at the Heart Failure Congress 2012, 19-22 May, in Belgrade, Serbia. The Congress is the main annual meeting of the Heart Failure Association of the European Society of Cardiology.
Aerobic exercise in patients with heart failure improves quality of life and reduces heart failure related hospitalisations. However, many heart failure patients find it difficult to exercise. In Nordic walking, people use poles and their arms copy the motions of cross country skiing. It is one of the fastest developing forms of physical activity in Europe and is safe for older patients, especially those above the age of 65, making it a good possibility for patients with heart failure.
For the study (abstract P939)
12 patients with heart failure and 12 healthy adults did two submaximal six-minute walking tests on a level treadmill at a constant speed of 5km per hour. Participants did one test with Nordic walking poles and one without.
The researchers compared the cardiorespiratory responses during walking with and without poles. In the healthy group, compared to walking without poles Nordic walking increased oxygen consumption (VO2) by 4.9 ml/kg/minute (a median increase of 37%) and led to a higher respiratory quotient (median increase of 5%). Peak heart rate was 20 beats per minute higher, maximal systolic blood pressure (BP) was 15 mmHg higher, and fatigue level was increased by 2 points on the Borg Scale. All results were significant (p=0.05).
In patients with heart failure, compared to walking without poles Nordic walking increased VO2 by 2.9 ml/kg/minute (14.7%) and respiratory quotient by 18%. Peak heart rate was 15 beats per minute higher, maximal BP was 10 mmHg higher, and fatigue level was increased by 2 points. All results were significant (p=0.05).
In both the healthy group and patients with heart failure, there were no signs of cardiac ischaemia and no significant arrhythmias during the tests.
The researchers concluded that Nordic walking allows healthy people and patients with heart failure to safely increase the intensity of exercise and gain additional cardiorespiratory benefits from exercise.
"In Nordic walking we have a big workload because we use additional muscle groups," says lead author Andrzej Lejczak, a physiotherapist at the Military Hospital in Wroclaw, Poland, and a PhD student at the University School of Physical Education in Wrocław. "We walk with four limbs, so we're exercising our arms and legs at the same time - that's why we have such a beneficial response."
He adds: "The implication is that Nordic walking is safe to include in cardiac rehabilitation programmes for patients with heart failure."
Patients simply need to purchase Nordic walking poles, which cost about €50, then take two or three one-hour lessons. After that they can exercise on their own outdoors, without needing to visit the gym.
Previous studies by Mr Lejczak have shown that Nordic walking improves quality of life, aerobic capacity and physical fitness in heart failure patients.

Nearly halfway through 2012 and here we have a thriving oil boom in many areas of the U.S. The oil boom is our answer, our counterpoint, in an economy that continues to struggle in the aftermath of the 2008 financial collapse. And it's not just oil. It's natural gas, too. We have technological developments in drilling to thank for unlocking reserves of oil and natural gas under shale rock formations. The technology is called hydraulic fracturing, or "fracking," for short, and is responsible for both the good and bad of today's oil boom.

Obese adolescents with no symptoms of heart disease already have heart damage, according to new research.
The findings were presented at the Heart Failure Congress 2012, 19-22 May, in Belgrade, Serbia. The Congress is the main annual meeting of the Heart Failure Association of the European Society of Cardiology.
Obesity is a risk factor for cardiovascular disease, and previous research has shown that obese adults have structural and functional changes to their hearts. The current study (abstract P843)
investigated the relationship between body mass index (BMI) ...
Folic acid fortification of foods may reduce the incidence of the most common type of kidney cancer and a type of brain tumors in children, finds a new study by Kimberly J. Johnson, PhD, assistant professor at the Brown School at Washington University in St. Louis, and Amy Linabery, PhD, postdoctoral fellow at the University of Minnesota.
Incidence reductions were found for Wilms' tumor, a type of kidney cancer, and primitive neuroectodermal tumors (PNET), a type of brain cancer.
Since 1998, the U.S. Food and Drug Administration has mandated fortification of foods with ...
Washington, DC—Rising prices for care were the chief driver of health care costs for privately insured Americans in 2010, according to the first report from the newly formed Health Care Cost Institute (HCCI). The per capita spending on inpatient and outpatient facilities, professional procedures, and prescriptions drugs rose 3.3 percent in 2010 for beneficiaries under age 65 with private, employer-sponsored group insurance. HCCI data show that this 3.3 percent increase follows spending increases in 2008 (6.0%) and 2009 (5.8%).

Despite the ban on use of handheld cellphones and other portable electronic devices while driving in New York, these laws may not actually contribute to improved motorist safety. In fact, the Insurance Institute for Highway Safety (IIHS) has found that these laws have not made a difference.
In reality, bans on texting and driving may be causing more problems than they resolve. Because texting while driving is illegal, drivers often try to hide their phones in order to avoid detection -- resulting in their eyes being away from the road for even longer periods of time. ...
