Low physical function and low muscle mass increase the risk for accelerated bone loss in older hip fracture patients

Low physical function and low muscle mass after hip fracture increased the risk for accelerated bone deterioration in older hip fracture patients. Acknowledgement of the risk factors is important for bone health and overall recovery. “Substantial decrements in physical function, muscle and bone strength occur after hip fracture, which markedly increase the risk for a

New study may have the reason why heart medication gives muscle pain

A study from McMaster University has found a potential mechanism explaining why some people who take drugs to lower their cholesterol develop sore, aching muscles. The use of statin drugs to significantly lower cholesterol, and ultimately reduce the risk of cardiovascular disease, has become widespread and large-scale studies suggest that nearly half of Americans and

How much protein do you need for weight loss and muscle growth?

(HealthDay)—Low-carb, vegetarian, Mediterranean—whatever your diet, it’s important to get enough protein. Although research hasn’t yet pinpointed one perfect formula, experts say that the typical “recommended” daily minimums aren’t optimal, and that it helps to factor in your weight and activity level to determine how much protein you personally need. A good baseline for people who

Eating more of this nutrient supports muscle strength as we age

If protein is the king of muscle mass food, nitrate might just be the king of muscle strength food. A new Australian study has found eating nitrate-rich vegetables like spinach, rocket and lettuce significantly improves muscle strength and physical function as we age. Power food … the nitrates in spinach, the vegetable which fuelled Popeye’s

Muscle-building proteins hold clues to ALS, muscle degeneration

Toxic protein assemblies, or “amyloids,” long considered to be key drivers in many neuromuscular diseases, also play a beneficial role in the development of healthy muscle tissue, University of Colorado Boulder researchers have found. “Ours is the first study to show that amyloid-like structures not only exist in healthy skeletal muscle during regeneration, but are

Duchenne muscular dystrophy: How muscle cells journey to the dark side

Promoting repair of dystrophic muscles is a major goal in the treatment of muscular dystrophies but is complicated by the incomplete knowledge of the cellular and molecular events that drive muscle regeneration. Answers could lie in better understanding muscle repair—which resembles a delicate cellular dance choreographed by special cells called fibro-adipogenic progenitors (FAPs). Researchers already

People with low muscle strength more likely to die prematurely

Individuals with weaker muscles do not typically live as long as their stronger peers, according to new research from the University of Michigan. After adjusting for sociodemographic factors, chronic health conditions and smoking history, the study published in the Journal of Gerontology: Medical Sciences found that people with low muscle strength are 50 percent more

New information to understand regulation of muscle function in muscular dystrophy patients

Scientists from the University of Jyväskylä, Finland, and from University of Cambridge, United Kingdom, have found new functions and structural details of muscle attachment structures. The research is important for the basic understanding of regulation of muscle function, for instance, in muscular dystrophy patients and for muscle adaptation in physical activity and sports. In multicellular

Quantity over quality—larger muscles could compensate for poor muscle quality in chronic kidney disease patients

The size of muscles in patients suffering from chronic kidney disease (CKD) could be more important to maintaining good physical performance than muscle quality, new research has shown. In a paper published in the journal Nephrology Dialysis Transplantation, researchers from the University of Leicester have found that patients with large muscles had better physical function,

Muscle ‘switch’ may control the benefits of exercise

Some people respond well to both aerobic exercise and strength training, while others don’t. And some of us respond well to only one of those things, but not both. Scientists at Joslin Diabetes Center now have uncovered a surprising molecular “switch” that may help to explain why this happens. “We’ve identified an exercise-activated biological pathway

Stop Eating Chicken Breasts That Have White Stripes ASAP

An animal activist group wants you to think twice before chowing down on that grilled chicken sandwich. A video by Compassion in World Farming is urging meat-lovers to learn about “white striping,” a muscle disorder affecting chicken breasts. According to a 2013 study published in the Italian Journal of Animal Science, the condition ups fat

Inflammatory signals in heart muscle cells linked to atrial fibrillation

Interfering with inflammatory signals produced by heart muscle cells might someday provide novel therapeutic strategies for atrial fibrillation, according to an international team of researchers who have published their findings in the journal Circulation. “Atrial fibrillation is the most common heart arrhythmia, and it is particularly observed in the elderly human population, which is growing

Space-like gravity weakens biochemical signals in muscle formation

Astronauts go through many physiological changes during their time in spaceflight, including lower muscle mass and slower muscle development. Similar symptoms can occur in the muscles of people on Earth’s surface, too. In fact, it could affect everyone to some extent later in life. “Age-related skeletal muscle disorders, such as sarcopenia, are becoming a greater
