Weightlifting better at reducing heart fat than aerobic exercise

In the small study, researchers determined that a certain type of heart fat, pericardial adipose tissue, was reduced in patients who did weight lifting, but not in those who worked on increasing their endurance with aerobic exercise, according to a report published in JAMA Cardiology. Both forms of exercise resulted in the reduction of a second type of heart fat, epicardial adipose tissue, which has also been linked with heart disease.

“We were surprised by this finding,” said the study’s lead author, Dr. Regitse Hojgaard Christensen, a researcher at the Center of Inflammation and Metabolism and the Center for Physical Activity Research at the Copenhagen University Hospital.

While the study doesn’t explain why weight training would have a different effect from endurance training, “we know from other studies that resistance training is a stronger stimulus for increased muscle mass and increased basal metabolism compared to endurance training and we therefore speculate that participants doing resistance training burn more calories during the day – also in inactive periods-compared to those engaged in endurance training,” Christensen said in an email.

 

To explore the impact of different types of exercise on heart fat, Christensen and her colleagues recruited 32 adults who were obese and sedentary but did not yet have heart disease, diabetes, or atrial fibrillation.

The participants were randomly assigned to a three-month program of aerobic exercise, weight training or no change in activity (the control group). Each person had an MRI scan of the heart done at the beginning of the study and at the end.

Both types of exercise training reduced epicardial adipose tissue mass compared to no exercise: endurance training, by 32% and weight training, by 24%. However, only weight training had an impact on pericardial adipose tissue, which was reduced by 31% compared to no exercise.

“The resistance exercise training in this study was designed as a 45-minute interval type, medium load, high-repetition, time-based training,” Christensen said.

“Participants performed three to five sets of 10 exercises and the sessions were supervised. This specific exercise intervention alone was effective in reducing both fat depots of the heart. We did not combine resistance and endurance training, which would have been interesting to reveal their potential additive effects.”

While there are plenty of studies looking at the impact of reducing abdominal obesity, the new study is interesting because it looks specifically at the relation between exercise and fat (around the heart),” said Dr. Chadi Alraeis, a staff interventional cardiologist and director of Interventional Cardiology at Detroit Medical Center’s Heart Hospital.

Alraeis suspects, based on the new study, that the best way to combat heart fat is to do both endurance and weight training. “Along with the time you spend on the treadmill, you might want to add some work with dumbbells, or some lunges, sit-ups or pushups,” Alraeis said. “It might even be enough to bring some weights to the office so you can use them there. “

While the findings are interesting, “we don’t know what the implication of this is 10 years later,” Alraeis said. “We don’t know if outcomes are really being changed. We need some long-term studies to look at that.”

How to Keep Stroke at Bay

Stroke can affect everyone regardless of their age and sex. You might think that you’re healthy one minute then the next you’ve been hit by this cardio problem. Although those who often smoke, drink, and eat unhealthy meals are highly likely to suffer from stroke, you can never be too sure unless you learn how to keep this disease at bay.

If you want to avoid triggering stroke, these tips can help you out.

Pay attention to your emotions. Depression is a silent killer and one that can increase your risk of stroke. When you feel depressed, your body won’t function properly thus putting you at risk of suffering from various health issues with stroke being on top. If you are aware of your feelings, you will be able to get help from your family and even professionals to address this issue immediately.

 

Exercise more. Exercise has always been recommended by doctors to those who want to stay healthy because keeping your heart pumping and your blood flowing prevent buildup of plaque in your arterial wall. This also promotes more oxygen being delivered to different parts of your body which can boost their functions.

Sleep. If you think that late nights are good for your health, you should think again. Sleep plays an important role in your health as it is at this moment of rest does your body regenerate itself. Without proper sleep, you’re putting yourself at risk of suffering from high blood pressure which can trigger stroke when you are not careful.

Drink in moderation. If you often go out with friends or party all night, you’re probably drinking several bottles of booze every night. Although you’ll look cool in the presence of your friends, you are not actually helping yourself in terms of health. Too much alcoholic beverage can wreak havoc in your liver which can increase your cholesterol level and putting you at risk of suffering from stroke. Following the recommendation of one glass of wine for women and two glasses for men should be beneficial to you rather than drinking several bottles of beer.

Use olive oil. Cooking with palm oil, canola oil, and the like can increase your risk of stroke. A better option would be to switch to olive oil when cooking as it has low melting point and it contains plenty of nutrients that your body needs to combat various diseases including stroke. Using olive oil regularly will reduce your risk of stroke up to 40%.

Keep an eye on your weight. Another tip to keeping stroke at bay is to learn how to manage your weight. Going beyond the weight suitable for your age, height, and sex will already put you at risk of suffering from various cardiovascular diseases like stroke, heart attack, and high blood pressure just to name a few. If you keep your weight down by eating healthy foods and exercising regularly, you will be able to successfully keep stroke at bay.

Eating junk food can raise risk of bipolar disorder, depression

Feeling depressed? It’s time to cut out the unhealthy junk food from your diet as it increases the risk of psychological disorders including bipolar disorder and depression, said researchers.

Junk food is not only harmful for metabolism but also increases the risk of psychological problems such as bipolar disorder and depression, irrespective of personal characteristics such as age, gender, education and marital status, according to the study, published in the International Journal of Food Sciences and Nutrition, indiatvnews.com wrote.

High-sugar consumption was found to be linked with bipolar disorder, while fried foods or processed grains were associated with depression.

 

“Perhaps the time has come for us to take a closer look at the role of diet in mental health because it could be that healthy diet choices contribute to mental health,” said lead author Jim E Banta, Associate Professor at Loma Linda University, California.

“More research is needed before we can answer definitively, but the evidence seems to be pointing in that direction,” Banta added.

The findings provide “additional evidence that public policy and clinical practice should more explicitly aim to improve diet quality among those struggling with mental health”.

It also pointed out that “dietary interventions for people with mental illness should especially target young adults, those with less than 12 years of education, and obese individuals.”

For the study, the team of researchers reviewed data from over 2,40,000 telephone surveys conducted between 2005 and 2015.

Drinking carbonated beverages during and after exercise can cause kidney injury’

After an intense workout session, it is common for people to drink either water or soft drinks. But according to the latest study, while drinking water is safe and causes no harm to the body, carbonated beverages may lead to kidney damage.

According to the study, published in the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, it has been found that drinking soda after exercise is a big No-No — “The purpose of this study was to test the hypothesis that consuming a soft drink (i.e., a high fructose, caffeinated beverage) during and following exercise in the heat elevates biomarkers of acute kidney injury (AKI) in humans.”

The researchers recruited twelve healthy adults who were made to drink 2 litres of an assigned beverage during 4 hours of exercise in the heat. While half of the people were given a popular soft drink, the other half were given water to drink. They also had to drink 1 litre of the same beverages after leaving the laboratory. Stage 1 AKI was detected at post-exercise in 75 per cent of the participants in the soft drink trial compared to 8 per cent in water drinking trial.

 

Furthermore, according to the findings, “urinary neutrophil gelatinase-associated lipocalin (NGAL), a biomarker of AKI, was higher during an overnight collection period after the soft drink trial compared to water.”

The study further added, “Changes in serum uric acid from pre-exercise were greater in the soft drink trial than water at post-exercise. There were greater increases from pre-exercise in serum copeptin, a stable marker of vasopressin, at post-exercise in the soft drink trial than water. These findings indicate that consuming a soft drink during and following exercise in the heat induces AKI, likely via vasopressin mediated mechanisms.”
