Endurance athletes have used tapering for years; now there’s evidence that exercise enthusiasts and strength and power athletes can benefit from tapering phases in their resistance training (RT) programs. So, is tapering right for your clients? And when it comes to RT, can less work lead to more success? Here’s what the research tells us.

Much of the periodization literature to date has centered on the strength outcomes and sports performance of athletes striving to balance the needs of practice, conditioning and competition (Bartolomei et al. 2014). But many recreationally active clients seek to gain muscle size in personal training sessions, and few studies have evaluated whether a periodization model should be used in a hypertrophy-focused resistance training program for these fitness enthusiasts. This article highlights the best research available to help answer an important question: Should you periodize a client’s RT plan to maximize skeletal muscle hypertrophy?

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.

Here’s more support for the benefits of recreational running. Data analysis from more than 19,000 male and female adults over an average of 6.5 years showed that leisure-time running was linked with a reduced risk of developing type 2 diabetes.

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.

“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.

Do you work with a client who has fibromyalgia? Here’s some good news: In a study of 466 women with fibromyalgia, researchers found that those with higher levels of overall fitness also experienced higher health-related quality of life (HRQoL). Spanish researchers from various institutions conducted the study to determine which components of fitness would be most valuable to target in people with fibromyalgia.

A new study further supports the benefits of maintaining cardiovascular fitness during middle-age and beyond. In a study presented at the European Society of Cardiology’s EuroEcho 2019 meeting in Vienna, high cardiovascular fitness was linked with significantly lower death risks from heart disease, cancer and other causes for middle-aged and older women.

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.

Personal trainers often have female clients over the age of 40 who have similar complaints about losing muscle mass and gaining body fat. Although these changes aren’t unexpected and can be a normal part of the aging process, they are not inevitable. In fact, the right resistance-training program can positively affect body composition by reducing fat, maintaining and building muscle, and increasing strength in this population.
