Getting fit in midlife!


Exercising in your 40's, 50's and 60's is like saving for your retirement, experts say. Starting early is money in the bank, but even late bloomers can reap astonishing benefits.

"The game isn't over, even if you haven't been active," said Dr. Angela Smith , past president of theAmerican College of Sports Medicine .

"Aerobic fitness, bone health , agility, you may be able to catch up. It's remarkable to see the things people can actually do." Smith, a physician at Philadelphia Children's Hospital, said studies have shown that even octogenarians can double their strength with weight training. "There's good evidence that among people who have arthritis, the stronger have less pain, and that getting fit decreases the chance of having cancer," she said.

But if you're a former high school athlete who became sedentary as your temples grayed, don't expect your history to save you. "Some of the benefits you built up aren't going to maintain themselves if you become a couch potato," Smith said. "That wonderful bone strength you built in your 20's will melt away a lot faster if you don't stay active." Smith said logic dictates that 40-, 50- and 60-year olds need to pay attention to all components of fitness.


"Make certain to do flexibility, strength and aerobic training, even if you have to decrease the amount of impact. A jumping sport may be difficult. But many of the non-sport activities, swimming, weight training, yoga, people can do just fine in 40's, 50's, 60's."

Andrea Metcalf, a fitness expert and personal trainer for over 20 years, recommends bite-sized portions for the late beginners. "People who have never exercised don't have a good sense of body awareness or body movement, so we need to focus on simple patterns, on strengthening those stabilizing muscles," said Metcalf, whose forthcoming DVD, Keeping Fit: Strength, Cardio, Pilates, targets the midlife exerciser.

"We know that 10-minute segments will have a cardiovascular effect. So if you do a couple, in the next week you can bring that up," she said. Metcalf agrees it's never too late to start. "You'll feel the benefits within the first two weeks of doing any new program. In six weeks you'll see body changes. If you touch your arm it's going to feel stronger."

Dr. Wojtek Chodzko-Zajko, of the University of Illinois and the leader of the Active Aging Blueprint, a umbrella group which develops strategies to help people 50 and older increase physical activity. He thinks people should revisit their routines just as they do their retirement investments. "The 25-year-old kid that goes for a run without a warm-up will need to adjust that middle age, when he's more prone to injuries," Chodzko-Zajko said.

"The choice of most 40-year olds is not going to be same as most 60-year olds." He said studies in nursing homes have shown that strength-training residents increase their mobility. Some even get out of wheelchairs. "Even modest improvement is associated with huge differences in the quality of life." Chodzko-Zajko urges people to find the activity that makes sense to them. "Even walking the dog or spending time outside. Adopt active choices. Be active in your own way."

Metcalf says people who live to be 100 all have a fitness component. "Exercise is the fountain of youth. If you want to live to 100 you have to exercise ," she explained. So what's the best workout? "The one you'll do," she said. "All the rest is just marketing." 

Tai Chi improves arthritis pain

Participants who were recruited in the largest study of the Arthritis Foundation's Tai Chiprogramme, have shown improvement in pain , fatigue, stiffness and sense of well-being. 

Their ability to reach while maintaining balance also improved, said Leigh Callahan, the study's lead author, associate professor in the University of North Carolina at Chapel Hill School of Medicine and a member of UNC's Thurston Arthritis Research Center. 

"Our study shows that there are significant benefits of the Tai Chi course for individuals with all types of arthritis, including fibromyalgia, rheumatoid arthritis and osteoarthritis," Callahan said. 

"We found this in both rural and urban settings across a southeastern state and a northeastern state." 

In the study, 354 participants were recruited from 20 sites in North Carolina and New Jersey . They were randomly assigned to two groups. The intervention group received the 8-week, twice-weekly Tai Chi course immediately while the other group was a delayed control group. All participants received baseline and 8-week follow-up evaluations, after which the control group also received the Tai Chi course. 


To be eligible for study, participants had to have any type of self-reported, doctor-diagnosed arthritis, be 18 years old or older and able to move independently without assistance. However, they did not have to be able to perform Tai Chi standing. They were eligible for the study if they could perform Tai Chi seated, Callahan said. 

Self-reports of pain, fatigue and stiffness and physical function performance measures were collected at baseline and at the eight-week evaluation. Participants were asked questions about their ability to perform activities of daily living, their overall general health and psychosocial measures such as their perceived helplessness and self-efficacy. 

At the end of eight weeks the individuals who had received the intervention showed moderate improvements in pain, fatigue and stiffness. They also had an increased sense of well being, as measured by the psychosocial variables, and they had improved reach or balance, Callahan said. 

The results have been presented at the annual scientific meeting of the American College of Rheumatology in Atlanta . 

Fruits, veggies cut obesity risk in teens

Boston University School of Medicine (BUSM) researchers have found that Dietary Approach to Stop Hypertension (DASH) diet reduces obesity risk in adolescent girls. 

DASH diet emphasizes increased intake of low-fat dairy products, fish, chicken, and lean meats, and nuts, fruits, whole grains, vegetables, and legumes. They found girls who followed the DASH diet pattern had a lower incidence of excess weight gain as measured by body mass index (BMI) over the 10-year period of their adolescence. 

The researchers, led by Jonathan Berz, an assistant professor of medicine at BUSM, used data from the National Growth and Health Study to examine the effects of adherence to a DASH-style eating plan and its components on the change in (BMI) in a racially diverse sample of adolescent girls. 


The study enrolled 2,379 girls aged nine and 10 years in three cities starting in 1987 to 1988 who were followed for the next 10 years. "We created a modified DASH food-group score and focused on the seven DASH-related food groups," said Berz. 

"We found that study participants with the highest intake of DASH-like food groups had the smallest gains in BMI over time and the lowest BMIs at the end of follow-up, and those with the lowest DASH food pattern score (representing lowest adherence) had a mean BMI that was greater than the threshold for overweight as defined by the 85th percentile by age," he said. 
These findings were reported in the Archives of Pediatrics  Adolescent Medicine.
