Longevity News and Review provides readers with the latest information in breakthroughs pertaining to the extension of the healthy human lifespan. These news summaries are compiled by the American Academy of Anti-Aging Medicine (A4M; www.worldhealth.net), a non-profit medical society composed of 24,000 physician and scientist members from 110 nations, united in a mission to advance biomedical technologies to detect, prevent and treat aging related disease and to promote research into methods to retard and optimise the human aging process. Dr Robert Goldman, M.D., Ph.D., D.O., FAASP, A4M Chairman, and Dr Ronald Klatz, M.D., D.O., A4M President, physician co-founders of the anti-aging medical movement, distil these headlines and provide their commentary.
Email Hiatus Boosts Work Productivity
On-the-job productivity may be increased by simply removing email from employees’ responsibilities. Gloria Mark, from the University California/Irvine, and colleagues enrolled civilian employees at the US Army’s Natick Soldier Systems Center (Massachusetts), who were hooked up to heart rate monitors, while software sensors detected how often they switched windows. People who read email changed screens twice as often (an average of 37 times per hour, versus 18 times for workers removed from email), and were in a steady “high alert” state, with more constant heart rates. Those removed from email for five days experienced more natural, variable heart rates, and reported feeling better able to do their jobs and stay on task, with fewer stressful and time-wasting interruptions.
Dr. Klatz observes: “In finding that simply by removing e-mail from an employee’s daily routine helps to reduce stress and increase concentration, this team provides evidence to support the notion that fewer distractions may help to promote productivity.”
Vitamin C Optimises Exercise Benefits
While exercise is a key element for effective weight loss, overweight individuals tend to report a higher perception of fatigue and exertion during physical activity. Previous studies have suggested that vitamin C helps to offset fatigability. Corey J. Huck, from the University of Wisconsin, and colleagues completed a four-week long study involving 20 adults, average age 35 years and average BMI 34.3 kg /m2. All subjects consumed a calorie-controlled diet, and a segment of the study group received a daily supplement of 500 mg of vitamin C. At the start and end of the study, participants performed 60 min. of exercise at the intensity of 50% of predicted maximal oxygen consumption. Whereas both groups lost about 4 kg and no breathing differences were apparent between the groups, the vitamin C-supplemented group had significantly lower heart rates during exercise, as compared to the non-supplemented group. In addition, perceived exertion and fatigue (as evaluated by standardized scales) were both significantly reduced in the vitamin C group. The study authors conclude that: “These data provide preliminary evidence that vitamin C status may influence fatigue, heart rate, and perceptions of exertion during moderate exercise in obese individuals.”
Remarks Dr Goldman: Reporting that daily supplements of vitamin C may decrease heart rate during exercise, thereby reducing the perception of fatigue and exertion, these researchers reveal an important natural approach to improving physiological conditions that otherwise may impede an individual’s impetus to engage in exercise activity.
Cocoa Flavanol Lowers Blood Pressure
Eating just a small amount of flavanol-rich cocoa products may help to significantly reduce blood pressure. Sabine Ellinger, of the University of Bonn in Germany and colleagues, investigated the effect of the monomeric flavanol epicatechin, a potent type of antioxidant, on blood pressure using data from four meta-analyses of randomized controlled trials. Their results showed that the potential of epicatechin to lower blood pressure was dose-dependent, with larger doses leading to greater reductions. Consuming 25 mg epicatechin (contained in 50g of dark chocolate) per day led to a mean reduction of -4.1 mm Hg in systolic blood pressure and of -2.0 mm Hg in diastolic blood pressure. According to the researchers, such a reduction in systolic blood pressure is associated with a 10% lower stroke mortality and a 7% lower mortality from ischemic heart disease and other vascular diseases in middle-aged people.
Comments Dr Klatz: New findings show that eating a small amount of flavanol-rich cocoa products each day can help to significantly lower blood pressure. These study results add to the ever-growing body of data suggesting a functional health role for this food.
Anti-aging medicine is the fastest-growing medical specialty throughout the world and is founded on the application of advanced scientific and medical technologies for the early detection, prevention, treatment, and reversal of age-related dysfunction, disorders, and diseases. It is a healthcare model promoting innovative science and research to prolong the healthy lifespan in humans. As such, anti-aging medicine is based on solid scientific principles of responsible medical care that are consistent with those applied in other preventive health specialties. The goal of anti-aging medicine is not to merely prolong the total years of an individual’s life, but to ensure that those years are enjoyed in a productive and vital fashion.
