Growth hormone, athletic performance, and aging – Harvard

Can human growth hormones really benefit aging, like the elusive fountain of youth? In 1513, the Spanish explorer Juan Ponce de Len arrived in Florida to search for the fountain of youth. If he got any benefit from his quest, it was due to the exercise involved in the search.

Few men today believe in miraculous waters, but many, it seems, believe in the syringe of youth. Instead of drinking rejuvenating waters, they inject human growth hormone to slow the tick of the clock. Some are motivated by the claims of the “anti-aging” movement, others by the examples of young athletes seeking a competitive edge. Like Ponce de Len, the athletes still get the benefit of exercise, while older men may use growth hormone shots as a substitute for working out. But will growth hormone boost performance or slow aging? And is it safe?

What is human growth hormone?

Growth hormone (GH) is a small protein that is made by the pituitary gland and secreted into the bloodstream. GH production is controlled by a complex set of hormones produced in the hypothalamus of the brain and in the intestinal tract and pancreas. Continue reading

Higher Fitness Level Can Determine Longer Lifespan After Age 70 – Study

I am always happy to pass along another example of how valuable my eat less; move more; live longer mantra is in daily practice.

Researchers have uncovered one more reason to get off the couch and start exercising, especially if you’re approaching your golden years. Among people over age 70, physical fitness was found to be a much better predictor of survival than the number of traditional cardiovascular risk factors in a study being presented at the American College of Cardiology’s 68th Annual Scientific Session.

While high blood pressure, high cholesterol, diabetes and smoking are closely linked with a person’s chance of developing heart disease, these factors are so common in older people that the total number of risk factors becomes almost meaningless for predicting future health, researchers said. The new study suggests doctors can get a better picture of older patients’ health by looking at how fit they are, rather than how many of these cardiovascular risk factors they have.

Spoiler alert – on being 79 years old

First of all, please read and digest the facts contained in the photo below. I very much believe what it says and live my life accordingly. I think it paints a clear picture about the wonderful organic machines that are our bodies. As such, for the most part, I enjoy robust good health riding my bike nearly every day year ’round here in Chicago.

53086139_10214518369252993_6523680200180367360_n.jpg

Nonetheless, at 79 years old I am not a kid any more. This week I will be going to a physical therapist where I am getting treatments for lower back pains. In between visits to her, every day I do between 20 minutes and a half hour of physical therapy exercises which she has proscribed. I presently am working through some serious lower back pains.

On Friday I meet with a dental specialist who will be consulting on a problem I have under some bridgework on the upper right side of my mouth. That dental structure was put in over 20 years ago and has recently shown signs of age.

While I am not seeing a medical practitioner for the arthritis that afflicts my hands, I rub CBD oil on them regularly and roll Chinese exercise balls around in them to relieve the pain and increase my dexterity. You can read about my experience with CBD oil.

Other than that, President Lincoln, how did you enjoy the play?

I did not intend this post to be as much of a downer as I fear it may be, but I wanted to put out some of the facts of my life that are indicative of a guy who just turned 79 years old. The good news is that I am retired and need to answer to no one for my time.

I am very happy with my life and once this Midwest weather straightens itself out I look forward to being back riding my bike daily.

But, I also wanted to paint a fair picture of things on this side of the temporal spectrum.

Push-ups and heart health – Harvard

Active, middle-aged men able to complete more than 40 push-ups had a significantly lower risk of cardiovascular disease (CVD) outcomes—including diagnoses of coronary artery disease and major events such as heart failure—during 10 years of follow-up compared with those who were able to do less than 10 push-ups during the baseline exam.

“Our findings provide evidence that push-up capacity could be an easy, no-cost method to help assess cardiovascular disease risk in almost any setting. Surprisingly, push-up capacity was more strongly associated with cardiovascular disease risk than the results of submaximal treadmill tests,” said first author Justin Yang, occupational medicine resident in the Department of Environmental Health at Harvard T.H. Chan School of Public Health.

The study was published February 15, 2019 in JAMA Network Open.

Objective assessments of physical fitness are considered strong predictors of health status; however, most current tools such as treadmill tests are too expensive and time-consuming to use during routine exams. This is the first known study to report an association between push-up capacity and subsequent cardiovascular disease outcomes.

The researchers analyzed health data from 1,104 active male firefighters collected from 2000 to 2010. Their mean age was 39.6 and mean body mass index (BMI) was 28.7. Participants’ push-up capacity and submaximal treadmill exercise tolerance were measured at the start of the study, and each man subsequently completed annual physical examinations and health and medical questionnaires.

During the 10-year study period, 37 CVD-related outcomes were reported. All but one occurred in men who completed 40 or fewer pushups during the baseline exam. The researchers calculated that men able to do more than 40 push-ups had a 96% reduced risk of CVD events compared with those who were able to do less than 10 push-ups. Push-up capacity was more strongly associated with lower incidence of cardiovascular disease events than was aerobic capacity as estimated by a submaximal treadmill exercise test.

Because the study population consisted of middle-aged, occupationally active men, the results may not be generalizable to women or to men of other ages or who are less active, note the authors.

“This study emphasizes the importance of physical fitness on health, and why clinicians should assess fitness during clinical encounters,” said senior author Stefanos Kales, professor in the Department of Environmental Health at Harvard Chan School and chief of occupational medicine at Cambridge Health Alliance.

Lack of exercise damages us – WHO Report

Eat less; move more; live longer. The World Health Organization agrees. Following are the potential results of inadequate exercise for all age groups, according to the WHO.

– Insufficient physical activity is one of the leading risk factors for death worldwide.
– Insufficient physical activity is a key risk factor for noncommunicable diseases (NCDs) such as cardiovascular diseases, cancer and diabetes.
– Physical activity has significant health benefits and contributes to prevent NCDs.
– Globally, 1 in 4 adults is not active enough.
– More than 80% of the world’s adolescent population is insufficiently physically active.
– Policies to address insufficient physical activity are operational in 56% of WHO Member States.

WHO Member States have agreed to reduce insufficient physical activity by 10% by 2025.

What is physical activity?

WHO defines physical activity as any bodily movement produced by skeletal muscles that requires energy expenditure – including activities undertaken while working, playing, carrying out household chores, travelling, and engaging in recreational pursuits.

The term “physical activity” should not be confused with “exercise”, which is a subcategory of physical activity that is planned, structured, repetitive, and aims to improve or maintain one or more components of physical fitness. Beyond exercise, any other physical activity that is done during leisure time, for transport to get to and from places, or as part of a person’s work, has a health benefit. Further, both moderate- and vigorous-intensity physical activity improve health.

How much of physical activity is recommended? Continue reading

Mini workouts boost your health – Harvard

As an old retired guy, I don’t have much time pressure in my life these days, but I remember how imposing work,  family and social obligations can be on your schedule. Don’t let that keep you from working on living a healthy life.  As Harvard says in this Women’s Healthwatch post, it all counts.

Good news for people who struggle to find time for exercise: every little bit matters, even if your “workout” is broken up throughout the day. To come to this conclusion, researchers who published their results March 23 in the Journal of the American Heart Association looked at data from 4,840 people ages 40 and older who participated in the National Health and Nutrition Examination Survey from 2003 to 2006. People who spent the shortest amount of time in moderate or vigorous activity — 20 minutes or less daily — had the highest risk of dying during the roughly six-year follow-up period. But those who got at least an hour of moderate or vigorous activity cut that risk in half, and those who got at least 100 minutes a day cut their death risk by 76%. And they didn’t have to get those 100 minutes all at once. Even short bursts of activity at different points in the day added up to reduced risk.

According to the U.S. Dept of Health and Human Services:

Adults 18 to 64 should get:
2.5 hours/wk of moderate intensity exercise.
OR 1.25 hours a week of vigorous aerobic physical activity
Or Some combination of the above – equivalent episodes of at least 10 minutes spread throughout the week.

Exercise trumps weight loss for heart patients – Study

 

It seems to be that sedentary is fast becoming a dirty word when it comes to a healthy extended life. The more we act to remove it from our lives that better off we will be.

Increased physical activity, not weight loss, gives individuals with coronary heart disease a longer lease on life, according to a new study conducted at the Norwegian University of Science and Technology (NTNU).

NTNU researchers have found that heart disease patients can gain weight without jeopardizing their health, but sitting in their recliner incurs significant health risks.

Weight loss seems to be associated with increased mortality for the participants in the study who were normal weight at baseline. The survey, which is an observational study based on data from HUNT (the Nord-Trøndelag Health Study), was recently published in the Journal of the American College of Cardiology (JACC).

Researcher Trine Moholdt in NTNU’s Department of Circulation and Medical Imaging collaborated on the study with cardiologist Carl J. Lavie at the John Ochsner Heart and Vascular Institute in New Orleans, and Javaid Nauman at NTNU.

They studied 3307 individuals (1038 women) with coronary heart disease from HUNT. Data from HUNT constitute Norway’s largest collection of health information about a population. A total of 120,000 people have consented to making their anonymized health information available for research, and nearly 80,000 individuals have released blood tests.

HUNT patients were examined in 1985, 1996 and 2007, and followed up to the end of 2014. The data from HUNT were compared with data from the Norwegian Cause of Death Registry.

During the 30-year period, 1493 of the participants died and 55 per cent of the deaths were due to cardiovascular disease.

“This study is important because we’ve been able to look at change over time, and not many studies have done that, so I am forever grateful to HUNT and the HUNT participants,” said Moholdt.

Exercise and live longer

The study revealed that people who are physically active live longer than those who are not. Sustained physical activity over time was associated with substantially lower mortality risk. Continue reading

You don’t have to be ‘strictly vegetarian’ to reap the benefits

For the record, I was a vegetarian for five years in my middle 30’s. At the time I did yoga daily and lived a generally active lifestyle. I weighed around 150 pounds and felt great. I stopped my vegetarianism mainly for social reasons. I felt guilty telling a hostess that I didn’t eat meat and needed different food. These days, I do eat red meat, but very sparingly. I am very conscious of the bad fats and am concerned about clogging up my arteries in my old age. As it turns out, I am eating according to the guidelines of this study from Erasmus University Medical Center in the Netherlands.

According to new data, a diet rich in plant-based foods and low in meat — without strictly following a vegetarian or vegan diet — may offer protection against obesity in middle-aged and older adults.

Experts already know that diets that emphasize plant-based over animal-based foods — such as vegetarian or vegan diets — can decrease the risk of obesity.

However, scientists do not yet know how strictly these diets need to be followed to reduce the risk of becoming overweight or obese later in life. Continue reading

Increase life expectancy a decade with these five healthy habits – Harvard

Who doesn’t want to live longer? I am impressed every day by the number of much younger followers I am getting on this blog.  Herewith Harvard’s latest on living longer..

Maintaining five healthy habits—eating a healthy diet, exercising regularly, keeping a healthy body weight, not drinking too much alcohol, and not smoking—during adulthood may add more than a decade to life expectancy, according to a new study led by Harvard T.H. Chan School of Public Health.

Take this walking quiz …

I am on record as being a major fan of the benefits of walking. I have repeatedly called it the Cinderella of the exercise world because so few people appreciate it. After you take this quiz, you can check out my Page – Why you should walk more for lots more benefits.

WebMD has an excellent quiz  – Do you know the benefits of walking? which I hope I can entice you to take by clicking the link in the middle of this sentence.

pexels-photo-663437.jpeg

Here are a couple of teaser examples: You can get the answers by taking the quiz.

You will live longer if you walk at least this far in a week:

The answer explained : “Walking this much at a slow pace of 2 miles per hour can be enough to lower your risk of things like heart attacks, strokes, and heart failure by 31%. People who walked farther and faster got even more benefit, in case you needed some extra motivation.”

Women who walk 30 minutes a day cut their risk of stroke by this much

The answer explained : “Just a little can do wonders to help your blood move through your body the way it should. Any time you can spend walking is good, but push yourself a little: Getting your heart rate up can strengthen it and lower your blood pressure.”

Walking is as good for your heart as running – True or False?

The answer explained : “For years, many experts thought that really pushing yourself — and your heart rate — was the best way to strengthen your heart. But ….”

How about walking if you suffer from arthritis?

I hope I have given you enough reasons to take the quiz. Knowledge is power and you will definitely learn something from this most useful exercise.

Night Owls Have Higher Risk of Dying Sooner – Study

I started taking courses in various aspects of good health and nutrition back eight years ago when I first started working on this blog. I created the Page – How important is a good night’s sleep? in 2013, so regular readers have been hearing about that aspect of good health since at least then. Here, we have a fresh insight into sleep habits that adds to the import of it.

A new study reports being a night owl might have significant consequences for your health, including an increased risk of dying earlier.

pexels-photo-545016.jpeg

“Night owls” — people who like to stay up late and have trouble dragging themselves out of bed in the morning — have a higher risk of dying sooner than “larks,” people who have a natural preference for going to bed early and rise with the sun, according to a new study from Northwestern Medicine and the University of Surrey in the United Kingdom (UK).

The study, on nearly half a million participants in the UK Biobank Study, found owls have a 10 percent higher risk of dying than larks. In the study sample, 50,000 people were more likely to die in the 6½ -year period sampled.

“Night owls trying to live in a morning lark world may have health consequences for their bodies,” said co-lead author Kristen Knutson, associate professor of neurology at Northwestern University Feinberg School of Medicine. Continue reading

Some insights into weight and aging – Web MD

I love these WebMD quizzes. I thought this was a particularly germane one for us.

There are only nine questions, but I want to offer a couple of sample. You can take the quiz here.

exercising
I only missed a couple (wheew!). Since I have been writing this blog for nearly 10 years, I expected to crush it.

Here are a couple of examples:

True or False – Thinner is better as you get older. Unlike the majority of our lives, things change as we age. The answer is, “You want to be healthy, not frail. For older adults, what matters most is how active you are and whether you can do all your everyday activities. While it’s important to stay at a healthy weight, how much of your weight ”

I thought that was an excellent insight which many people would not know.

True or False. Gaining weight is a fact of aging. This one is also not obvious. “You can keep your weight steady as you age. It does get harder, but it’s possible. Those corners you cut when you were younger (huge portions, happy hours, little to no exercise)? You can’t   But age doesn’t have to equal weight gain.”

I must admit that the statement, You can’t get away with them anymore, is, I think, no secret to any of us over 50.

HOW TO LIVE A LONGER AND HEALTHIER LIFE

There are some excellent insights here on the eating aspects of living a long and healthy life.

venitism

Biochemist Valter Longo has devoted decades to discovering connections between nutrition and successful aging. He runs the Longevity Institute at the USC Leonard Davis School of Gerontology, where the focus is on extending healthy life spans and finding ways to prevent and treat conditions like cancer and cardiovascular disease that growing older makes us more susceptible to developing. Longo is also a professor of biological science at the USC Dornsife College of Letters, Arts and Sciences.

Armed with results from the lab — including clinical trials showing that cycles of a five-day fasting-mimicking diet can reduce risk factors for many life-threatening diseases — Longo is calling for change in the kitchen. In this Q&A, he reveals the role that food can play in keeping us youthful and tackles some common misconceptions related to how, what and when we should eat.

How to age more slowly

Here is further information on the goal and idea of living a long life with a functioning brain throughout.

Tony

True Strange Library

Centenarians reach age 100 because they age more slowly. Genetics play a part in resisting damage that accumulatesover time, but there are things anyone can do to slow the aging process and improve health.

According to Israeli physician Nir Barzilai of the Institute for Aging Research at Albert Einstein College of Medicine in New York:

“There is no pattern. The usual recommendations for a healthy life — not smoking, not drinking, plenty of exercise, a well-balanced diet, keeping your weight down — they apply to us average people. But not to them. Centenarians are in a class of their own.” …

“Today’s changes in lifestyle do in fact contribute to whether someone dies at the age of 85 or before age 75.

But in order to reach the age of 100, you need a special genetic make-up. These people age differently. Slower. They end up dying of the same diseases…
