Exercise Reduces Colon Cancer Growth

Colon cancer cell growth slows immediately after a HIIT session, according to a pilot study published in the Journal of Physiology (2019; 597 [8], 2177-84). More physical activity is linked with a lower death risk for people with colorectal cancer.

Fitness Predicts Longevity After 70

Most adults over age 70 have multiple risk factors, such as high blood pressure, high cholesterol and/or diabetes, but experts note that knowing the total number of risk factors is not helpful for predicting future health. By contrast, knowing how fit a person is can be predictive, according to a study presented at the American College of Cardiology’s 68th Annual Scientific Session in March 2019.

Healthy Lifestyle and Dementia

A healthy lifestyle that includes regular physical activity, a healthy diet, moderate alcohol consumption and no smoking can significantly reduce the risk of developing dementia, even for people with genetic risk factors.

Sitting Increases Health Risks Independent of Exercise

It’s likely you have many clients who work sedentary jobs. Encourage them to simply move as much possible because, according to research,
people who sit for many hours, regardless of whether or not they exercise regularly, are at increased risk of higher liver-fat levels, a leading contributor to type 2 diabetes.

2019 IDEA® World Convention: Igniting Passion With Purpose!

Purpose, passion and people! The fitness industry is all about forging relationships that lift others up. Fitness professionals have energy to spare, and they are dedicated to mentoring new generations of pros, networking with peers, and motivating clients and participants every day.

Evening Cardio Training and Hypertension

In another clinical trial examining the impact of time of day on training effects, researchers found that cycling at moderate intensity for 45 minutes three times per week in the evening decreased clinical and ambulatory blood pressure in 50 middle-aged sedentary men with hypertension more than either morning training or stretching (the control group).

Walking Benefits Older Adults With Arthritis

People with osteoarthritis who walk briskly as little as 1 hour per week can significantly increase their odds of remaining functionally independent. Northwestern University researchers in Chicago examined more than 4 years of data from more than 1,500 adults—age 49 or older—who had arthritis but no disability. Their activity levels varied. Activity data analysis showed that people who did 1 hour of moderate-to-vigorous activity per week had a higher probability of remaining free from disability than those who exercised less.

Two of a Kind

When Colleen Evans wanted to improve her strength while healing from Lyme disease, her doctor knew exactly who could help her: fellow patient and personal trainer Shona Curley.

Like Colleen, Curley had been diagnosed with Lyme disease and was coping with its symptoms.

July 2019 Question of the Month: Eggs and Cholesterol

Here we go again. Just when we thought we could eat our omelets guilt-free, out comes another headline-grabbing study published in the Journal of the American Medical Association that rekindles the debate on whether we should fret about cholesterol intake.

Take the Steam Out of Tea Time

Tea is the drink of choice for more than a billion people. Recent decades have borne witness to a raft of research suggesting that sipping the ancient beverage brings certain health perks. But it is best to brew your cuppa and then let it cool.

Breast Cancer Survivors and Group Exercise

Research shows that exercise benefits breast cancer survivors, but many do not stick with programs. What might appeal enough to increase adherence? A pilot study found that group exercise designed specifically for people surviving breast cancer resulted in more improvements to quality of life than similar exercise programming led by personal trainers. The study is available in Oncology Nursing Forum (2019; doi:10.1188/19.0NF.185-97).

Changing Behavior Changes Lives

In North America—and around the world—people are suffering or dying from the ravages of chronic lifestyle diseases that are mostly preventable. It’s troubling to write those words as a flat statement of fact, especially in an era of such astonishing medical advancements paralleled with a daily firehose of new health research that further pressure-washes what we already know.

Short, High-Intensity Weight Training and Diabetes Risk

Preliminary research on high-intensity training benefits may motivate people who prefer short training sessions and are concerned about diabetes risk. University of Glasgow researchers in Scotland found that 15-minute strength training workouts, done three times a week for 6 weeks, dramatically improved insulin sensitivity and boosted muscle size and strength among 10 young, overweight men.

Can Exercise Prevent Depression?

Fifteen minutes of vigorous activity or approximately 1 hour of moderate activity (like walking or gardening)—or a combination of light and vigorous physical activity—may significantly reduce risk of major depression, according to a study published in JAMA Psychiatry (2019; doi:10.1001/jamapsychiatry.2018.4175).

UK Med School Includes Physical Activity Education

Lancaster Medical School in Lancaster, England, has been acknowledged throughout the United Kingdom and by the World Health Organization Europe for being the first medical school in the U.K. to integrate guidelines on how to prescribe physical activity. The initiative is referred to as the “Movement for Movement.”

Obesity and Cancer Risks in Young Adults

Recent findings reveal a trend toward increased risk for obesity-related cancers among young American adults. The study, published in The Lancet, found significant increases in six of 12 obesity-related cancers in young adults, with even greater rises in successively younger generations. Compared with people born 1945-1954, for example, those born 1980–1989 had double the risk . . . at the same age.
