Cardio/Aerobic

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.

Sample Class: Barre-Cardio-Core

When you take the strong, efficient movements of barre and mix in cardiovascular intensity and a comprehensive core routine, you get a winning combination that appeals to a wide variety of people. Traditional barre classes use small, repetitive movements from a standing posture to work on balance while strengthening the lower body. Simultaneously, the upper body receives graceful range-of-motion benefits. These movements prepare the body to progress to more intense cardio work, and the core section challenges the center from all directions.

Stop and Smell the Daisies

Brenda Badish had almost given up hope that she could regain her health. “I figured I was a few weeks away from pushing up the daisies,” she says.

Gender Differences in Fitness and Brain Function

Many studies show that cardiorespiratory fitness improvements boost brain fitness in later life. New research in the Journal of Applied Physiology (2019; doi:10.1152/japplphysiol.01046.2018) reveals that effects may differ between men and women.

Exercise Promotes Brain Fitness in Everyone

Much research on cardiovascular training for brain fitness focuses on benefits to older adults (see below). A recent randomized clinical trial using parallel groups found that cardio training also increases executive function in adults as young as 20 years old.

Cardio Training and Weight Loss

A systematic review of 77 studies suggests that while both interval training and continuous moderate-intensity exercise are effective for fat loss, interval training may produce results in a more time-efficient manner. Researchers from Brazil and England conducted the review to identify what type of exercise—continuous moderate-intensity (MOD), high-intensity interval training (HIIT) or sprint interval training (SIT)—is best for weight loss.

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).

June 2019 Question of the Month: HIIT Programs

What is the status of HIIT programming at your facility? What programs, if any, are you offering, and are they growing or declining in popularity or remaining the same? Are they popular with a specific demographic group, or do they have broad appeal? Share your insights on HIIT programs and your experiences with them.

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.”

Stair-Climb Your Way to Health

You may want to start recommending exercise snacking, particularly for people who believe they have no time for training. A few minutes of vigorous stair climbing, spread out in three bouts per day, three times a week, improved cardio fitness in formerly inactive young adults. McMaster University and UBC Okanagan researchers in British Columbia conducted the 6-week study.

Weighted Step-Training Benefits

If you’re looking for a different way to progress a client’s lower-body strength, consider adding a weighted vest to the training program. Specifically, wearing a progressively heavier weighted vest while stepping may be effective in boosting lower-body power and functional ability among older women.

The Fourth Trimester: Postpartum Exercise

It’s not over in 9 months. A new mother’s body keeps changing long after the baby arrives. Hormonal shifts, breastfeeding and risks like pelvic organ prolapse (see “3 Issues for Postpartum Exercisers,” below) complicate the weeks and months after childbirth.

Kickin’ Cooldown: Post-Kickboxing Stretches

Kickboxing is an empowering class that builds confidence and improves balance, cardiovascular endurance, proprioception, strength and dynamic flexibility. It’s an effective total-body workout, especially when taught correctly, with key tenets in mind. Some say kickboxing is on the downswing; however, it’s possible that any decline in popularity is due, not to the format itself, but to how it’s being taught (or mistaught). It continues to be a staple in many facilities.

More Long-Term Aerobic Fitness Benefits

New research adds to growing evidence that current cardiovascular fitness levels affect heart disease risks as far ahead as 9 years in the future. “Even among people who seem to be healthy, the top 25% of the most fit individuals actually have only half as high a risk [of heart disease] as the least fit 25%,” said principal investigator Bjarne Nes, PhD, of the Norwegian University of Science and Technology, Trondheim, Norway.

Rewards of Lifelong Exercise

If you were to tell clients they could have the heart health of a 40-year-old and the muscular fitness of someone in their 20s when they were in their 70s, they’d likely want to know more. Well, you could tell them this: A recent study found that lifelong exercisers averaging 75 years old had the cardiovascular health typical of someone in their early 40s and the muscular health of a 25-year-old. The key is to exercise regularly, year after year.

Inside the Latest Physical Activity Guidelines

The more we move, the better we live. Even a few minutes of exercise is better than sitting still.

These are just two of the conclusions in the recent report from the 2018 Physical Activity Guidelines Advisory Committee, whose recommendations form a sound foundation for integrating exercise into our daily lives.
