Just 10 minutes of exercise a day appears to sharpen mental prowess, new research suggests. “Getting off the couch and walking a block can help keep you on the right track,” said study author Nicole Spartano, a research assistant professor at Boston University School of Medicine. Her team looked 2,770 participants in the Framingham Heart Study who were divided into two groups: middle-aged and older. The Framingham study has followed the health and habits of its original participants from Massachusetts and their descendants since 1948. The researchers found that roughly 10 to 20 minutes of moderate to vigorous activity a day was associated with better brain function for both groups. For the middle-age group, just 10 minutes of moderate to vigorous activity was linked to better verbal memory. For the older group, the total amount of activity — not the intensity — corresponded to stronger mental skills. While the study only found associations, Spartano said the findings were especially significant for older people, who may find it difficult or impossible to meet the exercise guidelines set by the U.S. Department of Health and Human Services. Those guidelines recommend at least 150 minutes a week of moderate-intensity aerobic activity for them. A 2018 update of those guidelines does say older adults should do as much exercise as their health safely allows, and for all adults, any… read on >

(HealthDay News) — Hand swelling during exercise is a common issue. Exercise increases blood flow to your heart, lungs and working muscles and may reduce blood flow to your hands. Experts believe reduced blood flow may lead to widening blood vessels in the hand, and subsequent swelling, says Mayo Clinic. To ease hand swelling discomfort related to exercise, Mayo suggests: Remove rings and loosen watch bands before exercise. Perform occasional forward and backward arm circles during exercise. Stretch your fingers wide, then make fists several times during exercise.

Are you still having a hard time getting your kids to eat their fruits and vegetables? Studies, including one in the Journal of the Academy of Nutrition and Dietetics, show that a successful solution is to grow your own. Kids get excited as they watch a garden produce and are more motivated to eat what they had a hand in growing. Gardening is also a great way to get in extra exercise and reap the benefits of time spent outdoors in fresh air and sunshine. Whether you have a small patio bucket or can allocate square footage in your backyard, start your planning well before spring. Use online resources like Chicago Botanic (chicagobotanic.org) in the North, and Georgia Organics (georgiaorganics.org) in the Southeast to determine your climate zone and the right planting times. To get kids interested, the Arizona Farm Bureau suggests looking through colorful seed catalogs with them and letting them help pick out the choices. On the other hand, you don’t need to fill them in on every last prep detail unless they want to know. To avoid having them feel overwhelmed by the new activity, be sure to keep their responsibilities age appropriate. Older children can be more involved from the planning and design of the garden to harvesting, and even preserving some of the foods. Younger children can help with planting… read on >

Whether you’re mountain biking, kicking a soccer ball with friends, or just sprinting down the street to catch a bus, your quadriceps are hard at work. The quads are the large muscles that run down the fronts of your thighs. The stronger they are, the less strain each movement will exert on your knees. Lunges and squats will keep these muscles in tip-top shape. The basic squat involves a motion similar to sitting down in a chair. Stand straight, feet shoulder-width apart, toes forward. Keeping good posture, lower your hips until your thighs are parallel to the floor. You might have to work up to this over time, going a little deeper each session. Hold the position for two seconds before returning to the start position. As you get stronger, try the sumo squat. Start with your feet wider than your shoulders with your toes pointed out. Push your hips back and bend your knees, but no more than 90 degrees — your back will lean forward for support. After a few seconds, contract your glutes and slowly stand up. For lunges, start with feet shoulder-width apart. Step forward with your right foot, then lower your left knee almost to the floor as you make a right angle with your right thigh and calf. Bring your left foot up to meet the right and then… read on >

Winter sports such as skiing and snowboarding are a great way to get kids active, but new research suggests extra safety measures may be in order for younger children. The study found that grade-schoolers had almost three times the odds of having a serious skull or facial fracture while skiing or snowboarding, compared to older children. Meanwhile, older children had more than twice the risk of younger kids of having an injury to their abdominal area. “Injury prevention efforts need to be different for age group. There should be more targeted prevention strategies,” said study author Dr. Robert McLoughlin, a general surgery resident at the University of Massachusetts Memorial Medical Center in Worcester. McLoughlin doesn’t think the findings mean that kids should forgo winter sports. “It’s great that in a digital age where obesity is rising that kids get out and play, but they need to do it in a way that’s safe,” he said. Skiing and snowboarding are considered high-risk sports, even with protective equipment, the researchers said. Experts estimate that in 2015 there were more than 13,000 injuries related to snowboarding or downhill skiing in kids under 15. About 5% of those injuries required hospital admission. McLoughlin and his team looked at data from a nationally representative study of kids’ inpatient hospital admissions between 2009 and 2012. They found 845 admissions related to… read on >

Osteoarthritis is the most common form of arthritis, affecting about 31 million Americans, and is the leading cause of disability among adults. Known as OA, it causes pain and other symptoms in joints, which can affect the ability to do everyday tasks. There’s no known cure, but there are treatments that can relieve pain and maintain joint function, according to a rheumatologist at Wake Forest Baptist Health in Winston-Salem, N.C. “Osteoarthritis is the thinning or wearing down of cartilage, which is the cushion between the separate bones in a joint,” Dr. Francis Luk said in a health system news release. “When your doctor says you have arthritis, most often they are referring to osteoarthritis.” The main risk factors are aging, obesity, prior injury, repetitive stress on a joint and genetics. OA can occur in any joint, but the most common are knees, hips and hands. “Symptoms vary from person to person but someone with osteoarthritis of the knee typically will have pain when they stand up from a seated position or when they’re walking, especially when going up and down stairs,” Luk said. “With osteoarthritis of the hands, people typically experience pain when they do things that involve gripping — washing dishes, holding a wrench, opening a jar, things like that,” he added. Treatments include over-the-counter drugs such as acetaminophen (Tylenol) and nonsteroidal anti-inflammatory drugs,… read on >

The range of motion of the human thumb makes so many everyday hand movements possible. Whether you’re an athlete gripping sports equipment, a baker whisking egg whites or a do-it-yourselfer hammering a nail, you’d be at a total loss without your thumbs. Yet most people do little to protect these overlooked but essential digits. First, be aware of the common ways you can injure your thumbs. At the top of the list is overuse from texting and playing video games. Putting out your hand to cushion a fall is another cause. So is oxer-extending the thumbs when you’re playing tennis and when you’re skiing, typically when you fall if your hands get caught in your poles. To prevent problems, take steps to avoid overuse injuries and condition your thumbs just as you would any other body part. Give your thumbs a rest from texting by using your index fingers and/or the voice feature on your phone and other gadgets. Do daily stretches to improve range-of-motion and flexibility, like thumb extensions and flexions. With your palm up and fingers together, first extend your thumb out to the side to make a 90-degree angle with your hand, then cross your thumb over your open palm toward the base of your pinkie and hold for 10 seconds. Next, open and close your fingers in a fist. Finally do… read on >

If you’ve been told that your blood glucose is higher than normal and that you have prediabetes, your doctor is likely to first suggest lifestyle steps to stop it from progressing to diabetes. The steps that can have the most benefit are losing weight and improving your diet, which obviously go hand in hand. But studies also show that different types of exercise can play an important part in diabetes prevention as well, especially if you’re overweight. Research done at the University of Michigan and published in the Journal of Applied Physiology found that, for overweight people, regular aerobic activity could interrupt the changes in metabolism that set the stage for diabetes. As you’re mapping out a fitness strategy with your doctor, talk about how to incorporate both types of exercise into your life. National guidelines are to get 150 minutes per week of aerobic activity, which could be 30 minutes on each of five days or, for beginners, three chunks of 10 minutes each on five days. Strength training could be done on the two non-aerobic activity days as long as there is a rest period of at least 48 hours between sessions to give muscles time for recovery and growth. More information The U.S. Centers for Disease Control and Prevention has more on prediabetes and how to prevent it from progressing.

Universal gym etiquette includes steps like turning off your cellphone whenever you’re working out, being courteous when using shared equipment in the weight room, taking thoughtful steps such as not wearing heavy perfume, and wiping off your sweat after working out on a machine. But there are also good rules to follow whenever you walk into an exercise class. Adhering to them can improve your performance as well as your standing at the health club and your all-important relationship with your fitness instructors. First, use the minutes when you’re getting dressed for class to focus mentally. Get psyched for a serious workout and remind yourself that fitness boosts your motivation and enthusiasm. Being on time benefits everyone. Lateness is more than distracting to your instructor and classmates. You miss out on the important warmup segment, warns the American Council on Exercise, and that puts you at greater risk for injury. If you’re late for a personal trainer session, it throws off the rest of your trainer’s schedule and means less time for you. On the other hand, don’t be shy about asking questions that will help you improve and possibly avoid an injury. Don’t grin and bear it if a move hurts or if you’re unsure of how to do it. If you can’t get the attention of the teacher during class, bring up your… read on >

Don’t shrug off working your delts, the muscles of your shoulders. Besides assisting with good posture, strong shoulders help you lift and carry items with ease, and create excellent upper body definition for men and women alike. Deltoid rows work not only your shoulders, but also your biceps, lats and the muscles of your middle back. Begin in a standing position, knees slightly bent, with a dumbbell in each hand. Lean slightly forward from the hips, with a straight back. The weights should be just in front of your knees, with arms hanging down to the floor. Exhale and draw the weights straight up to your chest. Your torso stays still as elbows bend out to the sides — shoulders and upper arms should be in alignment at the top of the movement. Think of touching your shoulder blades as you hold for a second, then inhale and slowly return to the start position. Now move to deltoid raises. Stand with feet shoulder width apart, a dumbbell in each hand at the front of the thighs. With control, exhale and raise the weights out in front of you to shoulder height, arms parallel to the floor. Inhale and lower the weights to the start position. Finish with lateral raises. Start by holding the weights at your sides and, on the exhale, lift them out to… read on >
