According to a new study which examined the link between fitness and intelligence, classroom learning is not the only way to boost IQ. The study, published in Proceedings of the National Academy of Sciences followed over 1.2 million Swedish men. Researchers measured fitness level and IQ at age 18 years when they enlisted in the military and tracked academic achievement and job and socioeconomic status later in life. Researchers found that higher cardiovascular fitness was linked to better scores on IQ tests while muscular strength showed little relationship to IQ. They also reported that fit teens were more likely to obtain a college
Most of the readers of our blog agree with Dr. Cooper's frequently repeated message, "It is easier to maintain good health through proper exercise, diet, and emotional balance than it is to regain it once it is lost." The students who come to our classes, the community and school educators who disseminate our messages, and the men and women who volunteer for our research studies all seem to get it. A healthy lifestyle isn't always easy, there are no magic bullets or quick fixes, but day after day of healthy food and physical activity choices sure makes you feel good!
For many individuals, inactivity due to aging leads to a loss of physical conditioning which in turn can lead to loss of independent living. It is well documented that aerobic training and strength training improve cardiovascular conditioning, body fat, muscle mass, strength, functional independence and reduces the risk of diabetes, chronic diseases, falls, and fractures. Focus of the Study: The aim of this study was to compare exercise intensity progression for resistance training and aerobic activity in older and young women undergoing an Exercise Training (ET) program. The study population consisted of 33 physically inactive but healthy women, divided into
It seems like study after study reports parents making poor food and beverage choices and practicing fewer healthy eating behaviors like cooking at home and serving children breakfast. Results from a new survey, however, show that family nutrition and physical activity habits are improving. The American Dietetic Association Foundation’s 2010 Family Nutrition and Physical Activity Survey was administered nationwide to 1,193 pairs of children (ages 8 to 17) and their parents, examining eating habits and physical activity. The survey was previously conducted in 2003. Positive changes in family behaviors included: Since 2003, there has been a significant increase in daily family meals eaten at home, from 52 percent in
Can you believe that the holidays are upon us already?! While this can be a CRAZY time of year, I so look forward to visiting with family and friends. How about you? One visit you probably are not looking forward to though is a visit from the common cold. Adults experience on average 2-4 colds a year and children 6-10 with a higher prevalence during these fall and winter months1. And the cost of this illness adds up. A study looking at the economic effects of the common cold estimated that $40 million are spent on doctor’s bills, over the
One in six people worldwide will have a stroke in their lifetime. Just think of your five friends around you, one of the 6 of you will likely suffer from a stroke in your lifetime. Every 6 seconds, someone somewhere will die from a stroke.1 Stroke is the 3rd leading cause of death in the United States, with an estimated annual cost of more than $73 billion.2 Today is World Stroke Day with the theme “1 in 6” – appropriately named due to the unfortunate, but true statistics listed above – which are even worse for females, with worse outcomes
You may have thought that knee socks were back in style for athletes. Actually the knee socks you see runners and avid exercisers wearing are compression socks. They are specially designed thick, tightly woven socks or leggings that start below or at the ankle and cover the calf muscles. Although they have been used in the medical field for years, there is not much research on their use to improve exercise performance and enhance recovery in healthy individuals. For information on whole body compression garments, check out our July 19, 2010 blog. The basis of compression socks is the increased
In a previous blog we discussed how computer games can promote both unhealthy and healthy lifestyle choices (eating, physical activity) in children. To promote the development of healthy games First Lady Michelle Obama’s Let’s Move! campaign to end childhood obesity recently created the Apps for Health Kids competition. Apps for Healthy Kids challenged software developers, game designers, students, and other innovators to develop fun and engaging software tools and games that drive children, especially “tweens” (ages 9-12) to eat better and be more physically active. Submissions were due in June 2010 and the winners were recognized last month (September
Red Bull energy drink has led the 5 Billion dollar industry with more than 50% of all revenues. Since the popular emergence of energy drinks in 2002, there is now a popular trend toward sugar-free energy drinks that are mostly charged with caffeine. Caffeine is one of the most widely used ergogenic aids that various research studies have demonstrated increase aerobic endurance and reduce fatigue when consumed 60 minutes prior to workouts. However these “caffeine –endurance” studies included energy drinks that contained both carbohydrates and caffeine. Benefits of caffeine have been attributed to the increase in central nervous system activity.
While more and more overweight/obese Americans are turning to weight loss drugs and surgery, studies show that lifestyle change programs are still very effective for even the most obese persons. Two studies recently published in the reputable Journal of the American Medical Association showed that programs that include frequent weight management behavioral counseling (e.g., goal setting, problem-solving, education on healthy eating) via telephone or in-person; reduced calorie prepackaged prepared foods; and a prescription for exercise result in significant amounts of weight loss1,2. One study randomized participants to the Jenny Craig program (that included the existing program’s counseling, recommendations, and prepackaged
