Squat, Don't Sit: Study of African Tribe Shows Why One Position Is Healthier

Squat, Don`t Sit: Study of African Tribe Shows Why One Position Is HealthierMONDAY, March 9, 2020 (HealthDay News) -- You've probably heard the phrase, "Sitting is the new smoking," but what is it about sitting that's so harmful? New research suggests it's because sitting doesn't require much use of your body's muscles. The study compared the daily activities of a modern-day African hunter-gatherer community called the Hadza, in Tanzania. It found that while the Hadza spent similar amounts of sedentary time throughout the day as people living in more industrialized societies, what they didn't do was sit. Instead, they squatted or kneeled. "Squatting or kneeling requires light levels of muscle activity," said study author David Raichlen, a professor of biological sciences at the University of Southern California. That light level of muscle activity may...

Heading to Work on a Bike? You Might Live LongerTUESDAY, Feb. 25, 2020 (HealthDay News) -- Do you ride your bike to work? If you don't, maybe you should. Why? People who commute by bicycle are at lower risk of dying early, a new study from New Zealand finds. Researchers from the University of Otago, Wellington, the University of Melbourne and the University of Auckland found that those who cycled to work had a 13% reduction in death during the study period. Lead researcher Dr. Caroline Shaw attributes this mortality reduction to the health benefits of physical activity that aren't typically seen from walking or taking public transportation. For the study, Shaw and her team analyzed data from 3.5 million New Zealanders. "We studied 80% of the working-age population of New Zealand over a 15-year period, so it is highly...

Variety is Key for the Fittest Americans

Variety is Key for the Fittest AmericansMONDAY, Feb. 24, 2020 (HealthDay News) -- Very fit American adults enjoy a wider range of physical activities than those who are less active, a new study finds. The findings could help point to ways to boost physical activity in adults, according to the researchers. Data gathered from more than 9,800 adults nationwide between 2003 and 2006 showed that those who were active had done at least two different activities in the past month, but the most active did five. "Since a greater variety of activities was associated with meeting exercise guidelines, mixing up your workouts to vary the type of exercise could be beneficial," said study lead author Susan Malone, an assistant professor of nursing at New York University, in New York City. Walking was the most common activity, with more...

For Tracking Steps, Patients Stick With Phones, Not Wearable Devices: StudyMONDAY, Feb. 24, 2020 (HealthDay News) -- Smartphones appear to be more effective than wearable fitness devices in helping doctors track patients' physical activity, researchers say. Their new study included 500 patients who joined activity tracking programs at two Philadelphia hospitals. Half used a smartphone app to track their daily steps after leaving the hospital. The other half used a wearable device. Patients were instructed to send their step data to researchers on a regular basis. If they hadn't done so for four straight days, there were reminded via emails, texts or voice messages. During follow-up, patients using the smartphone app were more likely to relay their data than those with the wearable devices. Thirty days after hospital discharge, 87% of the smartphone group...

Exercise Surprise: Lifting Less Gets Better Results

Exercise Surprise: Lifting Less Gets Better ResultsWEDNESDAY, Feb. 19, 2020 (HealthDay News) -- Changing up the amount of weight they lift could help weightlifters get stronger with less effort, a new study suggests. In traditional weight training -- called one rep max -- the maximum weight an athlete can lift dictates the weight load for all sessions. This study compared one rep max with an approach called load velocity profile, in which athletes lift varying weights from session to session. Over six weeks, athletes who used the load velocity profile became stronger than those who used one rep max, despite lifting less overall, according to sports scientists at the University of Lincoln, in the U.K. The study, published recently in the Journal of Strength and Conditioning Research included 16 men, ages 18 to 29, with at least two...
