tweaking muscle metabolism prevents obesity and diabetes in mice




mildly stressing muscle metabolism boosts levels of a beneficial hormone that prevents obesity and diabetes in mice, according to a new study by researchers at the university of iowa.the new findings, published in the embo journal, show that triggering a certain type of metabolic stress in mouse mus...

is it harder to lose weight when you're older?




yes, unfortunately. although it is possible to lose weight at any age, several factors make it harder to lose weight with age.even those who remain active lose muscle mass every decade beginning in their 30s, research suggests, replacing it with fat. muscles use up more calories than fat, so less mu...



researchers establish basis of development of vertebrate limb muscles in cartila




the development of limb muscle has been well studied in most land dwelling vertebrates such as humans and modern research models. in these species, muscle precursors, or cells that will form limb muscle, travel to the limb bud, a location in the developing embryo where they multiply and form muscle ...



vegetarian diets almost twice as effective in reducing body weight, study finds




dieters who go vegetarian not only lose weight more effectively than those on conventional low-calorie diets but also improve their metabolism by reducing muscle fat, a new study published in the journal of the american college of nutrition has found.losing muscle fat improves glucose and lipid meta...



exercise-induced hormone irisin linked to new mechanisms for bone metabolism




boston (march 3, 2017)--two weeks of voluntary wheel running induces higher expression of irisin--a fat-burning hormone that is released during exercise--in bone tissue in mice. in addition, systemic administration of irisin increased bone formation and thickness, mimicking the effects of exercise o...

hiit workouts can reverse signs of aging




hiit—or high intensity interval training—has been the buzziest sweat method for a while now. these fast-paced workouts alternate short bursts of exercise with quick recovery periods, and torch more calories in less time than traditional steady-state training sessions. hiit has been shown to boos...



mayo discovers high-intensity aerobic training can reverse aging processes in ad




rochester, minn. -- everyone knows that exercise is good for you, but what type of training helps most, especially when you're older -- say over 65? a mayo clinic study says it's high-intensity aerobic exercise, which can reverse some cellular aspects of aging. the findings appear in cell metabolism...



seven ways muscle makes us healthier




working out with weights means different things to different people. it can be the buzz that comes with lifting a big barbell off the ground – or a way to make clothes fit better.but to professor rob newton, director of the exercise medicine research institute at edith cowan university, building m...



muscle fibers alone can't explain sex differences in bird song




male birds tend to be better singers than females—but does the basis for this difference lie in the brain or in the syrinx, the bird equivalent of our larynx? the researchers behind a new study from the auk: ornithological advances analyzed the muscle fibers in the syrinxes of male and female bird...



h&h question of the week: how do i add topline to a good-doer without feeding mu




spillers' equine nutritionist clare barfoot provides one h&h forum user with some helpful advice on how to add topline onto a horse who is a good-doerq:“my horse is a good doer. not overweight but has a good little grass belly. his ribs are still able to be felt. “he also lacks lots of muscle. a...

1 amvrka's 'american muscle' video: watch




los angeles-based duo 1 amvrka (pronounced “one america”) have set out to bring some light to the country amid its rather tough political climate, creating music with meaningful and a blend of hip-hop, folk-rock, country and pop. their latest song, "american muscle," does just that and bill...



muscle growth finding may assist with cancer treatment




monash university's biomedicine discovery institute (bdi) researchers have collaboratively developed a therapeutic approach that dramatically promotes the growth of muscle mass, which could potentially prevent muscle wasting in diseases including muscular dystrophy and cancer. the approach, jointly ...



how physical exercise prevents dementia




frankfurt. numerous studies have shown that physical exercise seems beneficial in the prevention of cognitive impairment and dementia in old age. now researchers at goethe university frankfurt have explored in one of the first studies worldwide how exercise affects brain metabolism.in order to furth...



common strength 'genes' identified for first time




common genetic factors that influence muscle strength in humans have been identified for the first time in a study led by researchers from the university of cambridge and published today in nature communications. the researchers used data on hand grip strength from more than 140,000 participants in ...



understanding the epidemiology of sarcopenia throughout the lifecourse




sarcopenia is an age-related syndrome which is characterised by progressive and generalised loss of muscle mass and strength. how prevalent is sarcopenia? as there is a lack of consensus in the operational definition used to characterized the disorder, estimates vary widely in different clinical set...

new understanding of how muscles work




muscle malfunctions may be as simple as a slight strain after exercise or as serious as heart failure and muscular dystrophy. a new technique developed at mcgill now makes it possible to look much more closely at how sarcomeres, the basic building blocks within all skeletal and cardiac muscles, work...



chimpanzee 'super strength' and what it might mean in human muscle evolution




since at least the 1920s, anecdotes and some studies have suggested that chimpanzees are "super strong" compared to humans, implying that their muscle fibers, the cells that make up muscles, are superior to humans.
