Published Lean body mass, age linked with alcohol elimination rates in women (via sciencedaily.com) Original source
Research links women's lean body mass with how quickly they eliminate alcohol from their system. Women with obesity and those who are older eliminate alcohol from their bloodstreams faster than those of normal weight and those who are younger.
Published Ketone supplements worsen performance in trained endurance athletes, researchers find (via sciencedaily.com) Original source
Kinesiologists at McMaster University have found ketone supplements, used by some athletes hoping to cross the finish line faster, may in fact worsen performance. The new study tackles contradictory research findings related to the effectiveness of ketone supplements, which have gained popularity among athletes seeking a competitive advantage.
Published New study gives clues on why exercise helps with inflammation (via sciencedaily.com) Original source
Researchers have long known that moderate exercise has a beneficial impact on the body's response to inflammation, but what's been less understood is why. New research done on a mouse model suggests that the answers may lie at the production level of macrophages -- white blood cells responsible for killing off infections, healing injury and otherwise acting as first responders in the body.
Published New study links contraceptive pills and depression (via sciencedaily.com) Original source
Women who used combined contraceptive pills were at greater risk of developing depression than women who did not, according to a new study. Contraceptive pills increased women's risk by 73 per cent during the first two years of use.
Published Taurine may be a key to longer and healthier life (via sciencedaily.com) Original source
A study finds that deficiency of taurine, a molecule produced in our bodies, drives aging, and taurine supplements can improve health and increase lifespan in animals.
Published The fast and the fibrous: Developing the muscles you need for speed (via sciencedaily.com) Original source
Researchers have identified the role of the large Maf transcription factor family in regulating fast twitch muscle fibers. A mouse model lacking Maf expression in the skeletal muscles exhibited a significant loss of type IIb myofibers, a subtype of fast twitch fibers. Overexpression of large Mafs promoted type IIb muscle fiber induction. The large Maf family may represent potential targets for developing treatments for muscular disorders involving fast twitch fibers.
Published Running throughout middle age keeps 'old' adult-born neurons 'wired' (via sciencedaily.com) Original source
A new study provides novel insight into the benefits of exercise, which should motivate adults to keep moving throughout their lifetime, especially during middle age. Long-term exercise profoundly benefits the aging brain and may prevent aging-related memory function decline by increasing the survival and modifying the network of the adult-born neurons born during early adulthood, and thereby facilitating their participation in cognitive processes.
Published Study finds brain connectivity, memory improves in older adults after walking (via sciencedaily.com) Original source
Regular walks strengthen connections in and between brain networks, according to new research, adding to growing evidence linking exercise with slowing the onset of Alzheimer's disease. The study examined the brains and story recollection abilities of older adults with normal brain function and those diagnosed with mild cognitive impairment, which is a slight decline in mental abilities like memory, reasoning and judgment and a risk factor for Alzheimer's.
Published Ready, set, go: New study shows how marathon running affects different foot muscles (via sciencedaily.com) Original source
Marathon running is a popular sport. However, long-distance running can weaken and damage foot muscles, leading to chronic pain and running-related injuries. A new study reveals that marathon running can reduce foot arch height, as well as induce damage to extrinsic foot muscles, which connect the lower leg and foot.
Published Researchers pinpoint brain cells that drive appetite in obesity (via sciencedaily.com) Original source
A group of brain cells discovered by researchers reveals a potential new approach to anti-obesity treatment.
Published Physical activity crucial for poststroke recovery (via sciencedaily.com) Original source
After a stroke, physical activity can be pivotal to successful recovery. People who spend four hours a week exercising after their stroke achieve better functional recovery within six months than those who do not, a new study shows.
Published Behavior patterns of people who achieve clinically significant weight loss (via sciencedaily.com) Original source
A new study analyzing data on over 20,000 U.S. adults links a healthier diet and increased exercise to weight loss that reduces heart disease risk -- while associating skipping meals and taking prescription diet pills with minimal weight loss, weight maintenance or weight gain.
Published New genetic target for male contraception identified (via sciencedaily.com) Original source
Discovery of a gene in multiple mammalian species could pave the way for a highly effective, reversible and non-hormonal male contraceptive for humans and animals. Researchers identified expression of the gene, Arrdc5, in the testicular tissue of mice, pigs, cattle and humans. When they knocked out the gene in mice, it created infertility only in the males, impacting their sperm count, movement and shape.
Published Sedentary time may significantly enlarge adolescents' heart (via sciencedaily.com) Original source
In adolescents, sedentary time may increase heart size three times more than moderate-to-vigorous physical activity, a recent article concludes. The researchers explored the associations of sedentary time, light physical activity, and moderate-to-vigorous physical activity with cardiac structure and function.
Published Bariatric surgery may reverse diabetes complications for people with obesity (via sciencedaily.com) Original source
For more than 100 million Americans who are obese, bariatric surgery may reverse complications related to diabetes, including regenerating damaged nerves, a new study shows. Researchers say the findings suggest that bariatric surgery likely enables the regeneration of the peripheral nerves and, therefore, may be an effective treatment for millions of individuals with obesity who are at risk of developing diabetes and peripheral neuropathy,
Published Smells influence metabolism and aging in mice (via sciencedaily.com) Original source
Exposure to female odors and pheromones causes weight loss and extend the life spans of mice, which may have implications for humans, researchers have found. While it was already known that sensory cues in humans and animals influence the release of sex hormones, this study shows that these cues could have more wide-spread physiological effects on metabolism and aging.
Published Being fit partially offsets negative impact of high blood pressure (via sciencedaily.com) Original source
High fitness levels may reduce the risk of death from cardiovascular disease in men with high blood pressure, according to a 29-year study.
Published How fit is your gut microbiome? (via sciencedaily.com) Original source
It is well known that the microbiomes of athletes are different from of those who are sedentary. To investigate how exercise shapes the gut microbiota in non-athletes, the study assessed information on the type, time and intensity of exercise in relation to microbiomes in a large cohort of middle-aged adults.
Published Study finds similar association of progestogen-only and combined hormonal contraceptives with breast cancer risk (via sciencedaily.com) Original source
There is a relative increase of 20% to 30% in breast cancer risk associated with both combined and progesterone-only contraceptives, whatever the mode of delivery, though with five years of use, the 15-year absolute excess incidence is at most 265 cases per 100,000 users, according to a new study.
Published Study shows 'obesity paradox' does not exist: Waist-to-height ratio is a better indicator of outcomes in patients with heart failure than BMI (via sciencedaily.com) Original source
New research has debunked the idea that there is an 'obesity paradox', whereby patients with heart failure who are overweight or obese are thought to be less likely to end up in hospital or die than people of normal weight. The study, which is published in the European Heart Journal, shows that if doctors measure the ratio of waist to height of their patients, rather than looking at their body mass index (BMI), the supposed survival advantage for people with a BMI of 25kg/m2 or more disappears.
