The Why: It's a very stylish watch that has all kinds of interesting features including a built-in pedometer to help keep you on track for walking 10,000 active steps per day without a transmitter belt. Using the latest in activity technology, an altimeter helps measure active steps and active time to provide an effective calorie count. The Activity Watch is great for hiking, running, or simply walking around and doing your regular activities. If you find yourself too busy for exercise, just strap on the Activity Watch and leave the calculating to the watch.


The Health Bonus: According to a recent walking study conducted by researchers from the University of Michigan Health System and VA Ann Arbor Healthcare System, when you use a pedometer or a device that tells you how long you've walked or run, you are more active.


What We Liked Best: Polar finally came out with a great looking watch that has some cool features besides a heart rate monitor with a strap.


What We Liked Least: While the watch has no familiar chest strap (that you typically find with almost every Polar watch), it also doesn't have a heart rate monitor. Polar, what were you thinking? Can't you please come up with this style watch along with a strapless heart rate monitor like the Mio ( )?


What It Replaces: Timex Ironman


The Price: $199.95


Other Offerings: This particular watch comes in only one style, but Polar offers many heart rate monitor / watches. See their offerings at

Nutritional Information: Walking at 3.0 mph will burn about 231 calories per hour for a 155 pound person.


Ingredients: The Activity Watch's accelerometer specifically measures forward motion and allows for the precise measurement of everyday physical activities such as choosing the stairs versus the escalator or walking the dog. It then combines personalized information including height, weight and age to provide accurate and useful output throughout each active period. The Activity Watch also features a built-in altimeter and barometer to measure both altitude and weather conditions for a more informed experience.

(Source: JAMA and Archives Journals ) Individuals who are physically active during their leisure time appear to be biologically younger than those with sedentary lifestyles, according to a report in the January 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Regular exercisers have lower rates of cardiovascular disease, type 2 diabetes, cancer, high blood pressure, obesity and osteoporosis, according to background information in the article. "A sedentary lifestyle increases the propensity to aging-related disease and premature death," the authors write. "Inactivity may diminish life expectancy not only by predisposing to aging-related diseases but also because it may influence the aging process itself."



Lynn F. Cherkas, Ph.D., of King's College London, and colleagues studied 2,401 white twins, administering questionnaires on physical activity level, smoking habits and socioeconomic status. The participants also provided a blood sample from which DNA was extracted. The researchers examined the length of telomeres-repeated sequences at the end of chromosomes-in the twins' white blood cells (leukocytes). Leukocyte telomeres progressively shorten over time and may serve as a marker of biological age.



Telomere length decreased with age, with an average loss of 21 nucleotides (structural units) per year. Men and women who were less physically active in their leisure time had shorter leukocyte telomeres than those who were more active. "Such a relationship between leukocyte telomere length and physical activity level remained significant after adjustment for body mass index, smoking, socioeconomic status and physical activity at work," the authors write. "The mean difference in leukocyte telomere length between the most active performed an average of 199 minutes of physical activity per week and least active minutes of physical activity per week subjects was 200 nucleotides, which means that the most active subjects had telomeres the same length as sedentary individuals up to 10 years younger, on average." A sub-analysis comparing pairs in which twins had different levels of physical activity showed similar results.



Oxidative stress-damage caused to cells by exposure to oxygen-and inflammation are likely mechanisms by which sedentary lifestyles shorten telomeres, the authors suggest. In addition, perceived stress levels have been linked to telomere length. Physical activity may reduce psychological stress, thus mitigating its effect on telomeres and the aging process.



"The U.S. guidelines recommend that 30 minutes of moderate-intensity physical activity at least five days a week can have significant health benefits," the authors write. "Our results underscore the vital importance of these guidelines. They show that adults who partake in regular physical activity are biologically younger than sedentary individuals. This conclusion provides a powerful message that could be used by clinicians to promote the potential anti-aging effect of regular exercise."
