For middle-aged and older adults who may not want to run, new research in the Mayo Clinic Proceedings (2019; 94 [12], 2413–26) shows that high-intensity interval walking effectively improves health and fitness. The protocol for this type of walking is 3 minutes at 70% of VO2max followed by 3 minutes at 40% of VO2max, repeated for 5 or more sets.

REHIT is a new training approach influenced by high-intensity interval training (HIIT), particularly its time-saving aspect. While a typical HIIT program lasts 30 minutes, a REHIT session consists of two or three 10- to 20- second sprints, separated by up to 3 minutes of recovery, in a 10-minute cardio session. Some experts believe this reduced-exertion approach may attract people who are inactive, have a chronic disease or simply lack time.

Keep refreshing your up-tempo playlists. Fast-tempo music increases overall exercise tolerance and reduces neuromuscular fatigue, according to a study reported in The Journal of Strength and Conditioning Research (2019; doi:10.1519/JSC.0000000000003417).

Resistance training may reduce fat levels around the heart (above), but not all strength-based activities are beneficial for cardiovascular health. New research shows that occupational activities like routinely carrying heavy loads at work may have a negative impact on the heart.

Location matters with body fat. The accumulation of excess fat around the heart can increase the risk of cardiovascular disease. A new study by researchers at the University of Copenhagen in Denmark assigned participants to resistance training, high-intensity interval endurance training (HIIT) or no exercise. Results showed that only people who lifted weights decreased the fat lying closest to the heart—specifically, inside the sac that encases the heart (the pericardium).

High-impact exercises — such as burpees, jumping jacks and other moves that get both feet off the ground simultaneously — can help build strength and endurance and shed fat quickly.
As a result, they’re often incorporated into high-intensity interval training (HIIT) workouts, which have gained recognition because they burn an impressive number of calories in a short amount of time and boost metabolism for up to 48 hours after the workout’s over through the afterburn effect.

“The message we get from the fitness industry is that your body is the problem, and it’s your job to fix it,” says Gillian Goerzen, author of The Elephant in the Gym: Your Body-Positive Guide to Writing Your Own Health and Fitness Story (Winchelsea Media, November 2018) and owner of the Super You Studio. This pressure can be even more pronounced in athletes — and in the fitness professionals who train them. In fact, according to the National Association of Anorexia Nervosa and Associated Disorders, some of the hallmarks of a successful athlete — mental toughness, commitment to training and pursuit of excellence — can easily slide into asceticism, excessive exercise and perfectionism, which are signs of anorexia nervosa.

Before you freshen up with anti-bacterial mouthwash after a heavy sweat session, ask yourself whether it’s really necessary. Working out commonly leads to a drop in blood pressure, but using an anti-bacterial mouthwash after training significantly reduces this benefit, according to a study published in Free Radical Biology and Medicine (2019; 143, 252–59). Rinsing with water, in contrast, does not affect blood pressure.

Get motivated to reboot your clients’ running programs for springtime. The good news: Any amount of running is associated with a 27% lower risk of death from any cause, a 30% lower risk of death from heart disease and a 23% lower risk of death from cancer, according to a study reported in the British Journal of Sports Medicine (2019; doi:10.1136/bjsports-2018-100493). An international team of researchers came to this conclusion after reviewing 14 studies that included more than 232,000 participants.

Women do not respond to weight training the same way men do. University of New South Wales researchers in Sydney conducted a comprehensive search of the literature on resistance training and found only 24 randomized controlled studies that focused exclusively on women. Lead study author Amanda “Mandy” D. Hagstrom, PhD, lecturer in exercise science at UNSW Medicine, said, “I was surprised. I knew there wouldn’t be many [studies], but I thought there’d be more than that.” The selected studies included almost 1,000 women.
