Exercise has countless benefits, even in small doses. And new research suggests the payoffs might extend to colon cancer patients. Short sessions of intense exercise may slow the growth of colon cancer, Australian researchers report. “We have shown that exercise may play a role in inhibiting the growth of colon cancer cells,” said lead author James Devin, from the University of Queensland. The report was published Feb. 27 in the Journal of Physiology. “After an acute bout of high intensity exercise, there were specific increases in inflammation immediately after exercise, which are hypothesized to be involved in reducing the number of cancer cells,” Devin said in a journal news release. Devin and his colleagues at the University of Queensland worked with researchers at the University of Waterloo in Ontario, Canada. The team took blood samples from 10 colon cancer survivors who had one session of intense exercise, and 10 survivors who had 12 exercise sessions over four weeks. Analyzing the samples for the growth of cancer cells, the researchers found that even one session of high intensity exercise appeared to reduce the growth of colon cancer cells. These short exercise bouts are as important as longer regular exercise, they said. The findings also suggest that continued exercise may aid in the “fight against cancer.” Moreover, they highlight the importance of regular exercise and leading a… read on >

Sweating it out on a treadmill is great, especially when the weather is bad. You might even be motivated by watching exciting vistas on an interactive panel. But to keep a walking or running routine from becoming stale, kick it up a notch by taking your workout outside. Running or walking in the great outdoors can burn more calories, because you have to work against the wind and you don’t have a moving tread to keep you going. If you’re used to monitoring the length of your treadmill workouts on a built-in screen, stay motivated by finding other ways to track your output. If you already have a smartwatch, there’s a good chance it has a step counter app already installed. If not, you can download any number of fitness apps that count time and distance, calorie expenditure and more. If you don’t have a smartwatch and are on a tight gadget budget, you can buy an inexpensive pedometer to count your steps. Remember that it takes about 2,000 to 2,500 steps to make a mile, depending on the length of your stride. Now you’re ready to rev up your walking/running. Here are four ideas you can mix and match. To add intensity to your outdoor workout and increase your cardio effort, choose a route with some hills. Pick up the pace with interval training.… read on >

(HealthDay News) — Flexibility helps prevent injury. Young athletes should stretch muscles before and after playing a sport, says the American Academy of Orthopaedic Surgeons. After warming up with a brisk walk, the AAOS suggests these stretches: Forward and side lunges. Standing quad pull. Seated straddle. Knees to chest.

If you’re bored with doing squats for a better bottom, it’s time to vary your workout. For a study sponsored by the American Council on Exercise (ACE), scientists at the University of Wisconsin-La Crosse evaluated popular exercises for the glutes to find the ones that are most effective. Popular Glutes Strength-Training Exercises Four-way hip extensions Horizontal leg press Lunges Quadruped hip extensions Single leg squats Step-ups Traditional squats Vertical leg press The traditional squat is still a great choice, but not the only one. In fact, if you want to target the hamstrings along with the glutes, quadruped hip extensions and step-ups are very effective. So are lunges, single-leg squats and four-way hip extensions. To get started, the experts at ACE recommend a super set of quadruped hip extensions followed by the step-ups. First, you do both exercises with one leg, and then you repeat them with the other leg, without any rest in between. For the hip extensions, get on hands and knees and contract your abs a bit to stabilize your core. Next, keeping the right knee bent at a 90-degree angle, lift your right leg until your thigh and the sole of your foot are parallel with the floor. With control, return to the starting position. Do eight to 12 reps. Immediately move to the step-ups. Stand behind a 15-inch-high step with… read on >

FRIDAY, Feb. 22, 2019 (American Heart Association News) — Jog for long enough or engage in just about any physical activity that gets the heart pumping, and the result can be a feeling of euphoria commonly known as a runner’s high. Sure, it feels good, but does higher-intensity exercise lead to better health? It can. Recently released federal physical activity guidelines emphasize the importance of any movement, but optimal health benefits require a little more effort. For adults, that means at least 75 to 150 minutes per week of vigorous activity, or 150 to 300 minutes per week of moderate-level physical activity. What constitutes high-intensity versus moderate exercise? It’s all about the heart rate relative to your fitness level, said Dr. Meagan Wasfy of the cardiovascular performance program at Harvard-affiliated Massachusetts General Hospital. “With low-intensity activities, most people will still be able to sing and converse,” Wasfy said. “At moderate intensity, you can still speak but can’t sing, and at high intensity, you can’t speak in full sentences anymore.” The new guidelines reflect a large and growing list of studies suggesting physical activity of any kind is healthyl. In a JAMA Internal Medicine study, researchers pooled data from six studies and found that over a 14-year period, people who never exercised were at the highest risk of death. But it didn’t take much activity to… read on >

(HealthDay News) — Winter can be hard for those watching their weight, the U.S. National Institutes of Health says. But you don’t have to wait until it warms up to burn those calories. Losing winter weight can start with equipment-free, in-home exercises: Squats. Push-ups. Planks. Wall sits. Lunges. Jumping jacks. Mountain climbers. Working out for 30 minutes each day can burn hundreds of cold-weather calories.

Have you been neglecting your calves? Many people forget about these important muscles when doing strength training. These exercises will add definition and help protect against some lower leg injuries. Start with seated calf raises. Sit on a chair or bench with feet flat on the floor. Lift your right heel as high as you can, pressing toes into the floor and flexing your calf muscles, then slowly lower your heel. Do this 12 to 15 times, then repeat with your left heel. Build to two sets of 15 reps with each leg. To increase your range of motion, place a block in front of your feet and position the ball of your foot on the block for the calf raises. To add resistance, place a weight cuff around the working thigh, about 3 inches from the knee. Now move to standing calf raises. Stand behind a sturdy chair, holding it for balance if necessary. With feet shoulder width apart, slowly rise up on your toes as you tighten your abs. Keep your back and knees straight. Hold briefly, then slowly lower heels to the floor. Build up to two sets of 12 to 15 reps. To increase the challenge, hold dumbbells at your sides, palms facing inward as you do the exercise. For another variation, lift your left foot off the floor while doing… read on >

Upper body strength is important at every age, but you don’t need to be a bodybuilder to benefit from working your pectoral, or chest, muscles. For a study sponsored by the American Council on Exercise, scientists from the University of Wisconsin La Crosse evaluated nine popular pec exercises to determine which ones best engaged these muscles. Popular Pec Strength-Training Exercises Barbell bench press Pec dec machine Bent-forward cable crossover Chest press machine Inclined dumbbell flys Dips Push-ups To develop muscle size, the barbell bench press is at the very top of the list, followed closely by the pec deck machine and the bent-forward cable crossover. Here’s how to perform the barbell bench press. Lie with your back flat on a weight bench. Knees are bent at the far end of the bench with feet flat on the floor. Grip the barbell with both hands, placing them slightly wider than shoulder-width apart. Elbows make a 90-degree angle. With control, lower the bar so that it’s just barely touching your chest, then press upward as you extend your arms. Hold briefly and, again with control, slowly lower the barbell to your chest for one complete rep. Repeat for the appropriate number of reps, typically up to 15 with a lighter weight, up to eight with a heavier weight. To protect against injury to your shoulders, focus on… read on >

A half-hour of morning exercise can help control blood pressure in overweight and obese people for the entire day, a new study finds. And for women in particular, adding frequent short breaks from sitting through the day can offer additional benefit, the Australian researchers said. “For both men and women, the magnitude of reduction in average systolic blood pressure following exercise and breaks in sitting approached what might be expected from antihypertensive medication,” said lead author Michael Wheeler. “However, this reduction was greater for women,” he added. Wheeler is a member of the Baker Heart and Diabetes Institute in Melbourne. The research involved 67 people between the ages of 55 and 80 who did three different laboratory sessions, in random order, separated by at least six days. Those sessions included: uninterrupted sitting for eight hours; one hour of sitting prior to 30 minutes of walking on a treadmill at a moderate pace, followed by 6.5 hours of prolonged sitting; and one hour of sitting prior to 30 minutes on the treadmill, followed by sitting that was interrupted every 30 minutes with three minutes of light-intensity walking for 6.5 hours. Average systolic (top number) and diastolic (lower number) blood pressure was reduced among both men and women who took part in morning exercise, compared to when they did not exercise. There was an additional benefit —… read on >

A typical workout doesn’t give you license to eat whatever you want. Even a full hour of vigorous skiing burns just 600 calories — less than the amount in a super-sized fast food sandwich. That’s why it’s important to think of exercise as just one part of a shape-up plan. Exercise works the cardiovascular system and builds muscle, but it takes calorie restriction to also lose weight. Small diet tweaks that you can make when you’re building a healthier body through exercise will maximize your efforts. Here’s what you need to know about nutrition when you work out regularly. You don’t need to fuel up like a marathon runner, but give your body some nourishment about two hours before every workout to make exercise more effective. Have a small meal with healthy carbs and protein, and some fat. If eating two hours in advance doesn’t work with your schedule, aim for a small snack about an hour before your workout. It’s also important to eat a small meal with carbs and protein within two hours after your workout to give your body the nutrients it needs. Keep in mind that “calories in and calories out” is a balancing act that varies from person to person. So whether you’re trying to lose weight or maintain, keep a journal that records the amount of calories you get… read on >
