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.
Are Compression Socks Effective?
A study involving amateur female soccer players found that those who wore compression socks during a match experienced less game-induced fatigue than teammates who wore regular socks. Investigators evaluated fatigue by testing agility, standing heel-rise and other factors immediately after the match.
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.
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.
June 2019 Question of the Month: Should Cities Help Shape What People Eat?
Like them or hate them, soda taxes are proving effective at curbing the intake of sugary drinks. A study published in the American Journal of Public Health cites data showing that after the city of Berkeley, California, implemented a penny-per-ounce soda tax in 2014, consumption of sweetened drinks, including soda and energy drinks, plummeted by 21% in lower-income neighborhoods. And 3 years later, city-polled residents reported drinking 52% fewer of these beverages than they did before the tax passed.
Children’s Diets Worsen With Age
Rising obesity rates in American children suggest that their diets leave a lot to be desired. Recently, researchers with the USDA Agricultural Research Service explored young people’s diets using the Healthy Eating Index (HEI), which measures how well diets align with federal Dietary Guidelines for Americans.
Media Multitasking: Another Link to Obesity?
Do any of your clients struggle with weight gain? If so, let them know about new research that has found that media multitasking has now been linked to obesity.
Research from Rice University indicates that mindless switching between digital devices is associated with increased susceptibility to food temptations and lack of self-control, which may result in weight gain (Lopez, Heatherton & Wagner 2019).
How to Improve Tennis Performance
Tennis is one of the most popular sports in the world. In the U.S. alone, there are almost 18 million players, with another 14 million expressing interest (TIA 2018). Unfortunately, the dynamic, forceful twists and turns of the game pose ever-present injury risks to players (Roetert & Kovacs 2011).
Career Advancement for Everyone
Thousands of fitness professionals consider the IDEA World Convention to be the best investment they can make to further their careers. That’s largely because the event delivers robust, multilevel education covering all facets of the industry. But there’s more to it than that, according to fitness industry veteran and this year’s IDEA Jack LaLanne Award recipient, Jay Blahnik.
Pilates Helps Adolescents
6-week Pilates program improved core muscle endurance and hamstring flexibility among adolescents between 9 and 19 years with a history of back pain. Research findings from a preliminary study published in Complementary Therapies in Clinical Practice (2019; doi:10.1016/j.ctcp.2019.01.006) showed that a 6-week Pilates mat exercise program with two 55-minute sessions per week can improve conditioning in both young males and young females.
Maternal Stress and Overweight Girls
The number of children with overweight or obesity—especially among kids younger than 6—is rising in modern societies. Being overweight before preschool increases the likelihood that children will develop obesity as they grow older.
Fitness Training Reduces C-Section Risk
Women in their third trimester of pregnancy who are highly physically active are less likely to have an acute cesarean birth than women with low physical activity levels, according to findings from the Norwegian Fit for Delivery study (a randomized controlled trial).
Fitness Pros Influence Body Satisfaction
Women in a group exercise class experienced greater body satisfaction and better moods when the instructor made motivational comments related to strength and health instead of weight or appearance.
Blood Pressure, Diet and Aging
It’s official: The typical Western diet is a major driver of rising blood pressure as we age, not age itself as previously thought, according to research from the Johns Hopkins University Bloomberg School of Public Health published in JAMA Cardiology. The study revealed that members of the isolated South American Yanomami tribe, with virtually no Western dietary influences, typically have no rise in their blood pressure numbers from age 1 to age 60.
Eat Fish for a Long Life
If you want to enjoy many more birthdays in great health, it could be a good idea to cast your line for omega-3-rich fish more often. In a 13-year study of older Americans, published in the journal BMJ, those with higher circulating blood levels of marine-derived, long-chain omega-3 fatty acids—such as docosapentaenoic acid—were significantly more likely to age healthfully than their peers with lower levels of these omegs-3s in their blood.
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.
The Power of Simple Lifestyle Changes
Lifestyle choices have a significant impact on quality and length of life. With many Americans living longer than ever, fitness pros are on the front lines of a complex challenge: How will we help people remain active and engaged from their 60s into their 90s and beyond? How can we help them stay healthy to rein in healthcare costs?
Debating Alcohol Consumption and Risk
In our September 2018 issue of Fitness Journal, we reported on an international study published in The Lancet that found any level of drinking above 100 grams of alcohol (3.75 ounces) per week increases heart disease risk and shortens lifespan.
Neuromuscular Power Circuits
The dynamic motions of sport require peak power—that is, the most strength a muscular contraction can muster in one of these quick bursts. Sporting athletes depend on peak power for jumping, running, throwing, striking, swinging and kicking. Scientists prefer the term “neuromuscular power” (to just “power” itself) because neural factors—including motor unit recruitment, muscle fiber firing frequency and synchronization of a muscle’s contractile forces—are involved.
The Key to a Prolific Career
Soccer great Pelé once said, “Success is no accident. It is hard work, perseverance, learning, studying, sacrifice and, most of all, love of what you are doing or learning to do.” This concept forms the foundation of everything you will experience at the 2019 IDEA® World Convention in Anaheim, June 26–30.
