Cardio/Aerobic

Exercise Program Can Restore Heart Muscle Health

Good news for people who have delayed starting a training program. If the following exercise regimen is begun before age 65, studies show that the heart muscle can regain elasticity, reversing stiffening that can develop from lack of physical activity. Cardiologists from the University of Texas Southwestern Medical Center and Texas Health Resources in Dallas have been studying how to promote health and elasticity of the heart muscle.

Sample Class: Sand Bell HIIT

More flexible and variable than dumbbells or kettlebells, sand bells are sand-filled disks that can be lifted, slammed, tossed, curled, or flipped like a heavy pancake. The following playful workout mixes high-intensity cardio and strength training with two levels of progression, creating a user-friendly class for any participant.

Sand Bell HIIT Details
FORMAT: strength and cardio conditioning
TOTAL TIME: 55 minutes

Kickboxing Safety: Back to Basics

Kickboxing classes may not be as popular today as they were in the late 1990s, but people still love to hone their skills with this effective cross-training option. Whether you’ve been teaching for several years or you’re just getting started, it’s always a good idea to review the foundational concepts that make up this total-body workout.

More Exercise Is Key to Weight Loss Success

New research may help solve the problem of why many people who increase their activity fail to lose weight. Although exercise burns calories, previous studies have shown that many people compensate for the increased activity by eating and resting more, thus negating some potential weight loss benefits.

Can a Short Bout of Cardio Affect Motor Skill Learning?

Fifteen minutes of aerobic exercise done immediately after practicing a new motor skill improves long-term retention of that skill, according to findings reported in NeuroImage (2018; doi:10.1016/j.neuroimage.2018.03.029). Lead study author Fabien Dal Maso, assistant professor at the University of Montreal, said, “This shows that exercise is not only good for the body; it is good for the brain.” Researchers conducted the study to explore brain mechanisms underlying motor learning and the impact of cardiovascular exercise on motor memory consolidation.

Moderate-Intensity Exercise Boosts Calorie Burning for an Entire Day

Need more convincing reasons to do a moderate-intensity workout on days when skipping training is attractive? New study findings show that energy expenditure increased for at least 22 hours after bouts of moderate-intensity (50% of peak) exercise, leading to an additional 64 (±119) kilocalories burned per day. Prior research had shown that high- but not moderate-intensity exercise increased resting energy expenditure.

Hot Yoga May Provide Heat Stress Conditioning for Athletes

If you’re looking for a good cross-training technique for your more athletic clients, suggest they practice hot yoga, which may boost aerobic performance while minimizing exercise stress.

University of British Columbia, Vancouver, researchers recruited 10 elite female field hockey players for observation. All athletes participated in 60-minute hot-yoga classes (30 degrees Celsius/86 degrees Fahrenheit) over 6 consecutive days, during which they did not engage in any other exercise. Following the intervention, the athletes played in a national-team camp.

Functional Aging and Hormone Health

Understanding functional aging and the impact of activity on hormones can arm fitness trainers to help clients with their active aging goals.

Never Skip a Beat!

As “head coach” of the circulatory/cardiovascular system, the heart pumps blood throughout the body, supplying oxygen and nutrients to tissues. Actually, two circulatory systems work as a “team”: Systemic circulation carries oxygenated blood from the heart to the body and sends deoxygenated blood back to the heart. Pulmonary circulation transports oxygen-poor blood from the heart’s right ventricle to the lungs, where it picks up a new supply of oxygen-rich blood that it carries to the heart’s left atrium (PubMed Health 2018).

Sample Class: The Playground

Do you remember recess? That break in the monotonous school day when you could run wild and free, lost in playful movement? The glory of the playground lingers in many of your participants’ memories too, and you can help to recreate that experience by taking your next class a little less seriously.

Turning the group fitness studio into a playground is a great idea for stressed-out, time-crunched, social media–weary adults who need a break from responsibility. So grab a whistle, cue the bell and get ready to inject some fun into everyone’s day!

Getting to the Heart of Pre-Exercise Screening

A preparticipation health screening helps trainers and prospective clients safely launch into an exercise program. When the American College of Sports Medicine updated its pre-exercise screening guidelines 3 years ago, it made one major shift: It stopped recommending the use of a tool to assess cardiovascular disease risk.

How Fast You Walk May Affect How Long You Live

Want to outwalk the grim reaper? Pick up the pace, say researchers. A new study from the United Kingdom suggests that quicker walking may add years to your life.
The study’s primary aim was to examine the impact of walking pace and volume on all-cause mortality. To determine this, researchers looked at mortality records for 50,225 individuals from Scotland and England who had self-reported their walking data via interview.

Exergaming May Improve Independence Among Older Adults

Maybe you’ve thought about integrating exergaming—exercise combined with video games and other elements of technology—into some of your classes or sessions. Don’t forget to include older adults. A recent study found that seniors with mild cognitive impairment (MCI), a precursor to Alzheimer’s, showed significant improvement in certain complex thinking and memory skills after exergaming.

Equal Calories Burned ≠ Same Results

Many people fixate on the number of exercise calories they burn. New research, sponsored by Les Mills International, shows that even when two group fitness activities (indoor cycling and a resistance workout) were matched for duration and caloric expenditure, they did not have equivalent metabolic effects—which could influence long-term training results. Lead study author Nigel Harris, PhD, said, “The type of exercise used to burn those calories . . . impacts the long-term positive effects that exercise has on the body.”
