Loss of antioxidant protein Nrf2 represses regeneration of muscle lost to aging

Posted March 10, 2014

Good news for lifelong exercisers: Along with its salutary effects on the heart, weight, and other facets of health, physical activity also helps to regenerate muscle mass, which tends to diminish as people age.

Muscle loss that comes with age can be fixed through better nutrition

Posted March 2, 2014

A cup of tea and a cookie for an afternoon snack, while a pleasant routine, may not be supplying adequate nutrition for many baby boomers, a recent Tufts study suggests. Substituting a glass of milk or a hard-boiled egg would better fuel the person who has reached that time in life—that is to say, anyone older than 50—when muscle mass declines at a rate of 1 to 2 percent annually.

Top 4 ways to reduce muscle and joint pain

Posted February 27, 2014

It seems that nearly everyone is dealing with some sort of muscle or joint pain. We often blame it on getting old, too much physical work or exercise, or other phantom factors that we obviously don’t understand. Regardless of our notion of how it happened, we all really want it to go away. Here are some simple solutions to start.

Postprandial muscle protein synthesis is higher after a high whey protein, leucine-enriched supplement than after a dairy-like product in healthy older people: a randomized controlled trial

Posted January 24, 2014

The aim of this study was to evaluate whether a specifically designed nutritional supplement in older adults stimulates muscle protein synthesis acutely to a greater extent than a conventional dairy product. Moreover, the combined effect with resistance exercise was studied by using a unilateral resistance exercise protocol.

IV vitamin C infusions reduce muscle fatigue associated with COPD

Posted December 5, 2013

Chronic obstructive pulmonary disease, or COPD, is a rather vague name for a chronic disorder that inhibits breathing and oxygen delivery to the blood. It manifests in decreased lung capacity from various reasons and inhibits breathing. It can get progressively worse, leading to chronic bronchitis or emphysema.

Vitamin C could ease muscle fatigue in chronic obstructive pulmonary disease patients

Posted November 8, 2013

Chronic obstructive pulmonary disease—a health problem in which the lungs lose their inherent springiness, making it progressively harder to breathe—can have a dramatic effect on the ability to exercise and even perform simple activities of daily life because of the disease’s fallout effects on skeletal muscles. Several factors have been implicated in these muscle problems.

Natural Betaine Shown to Support Muscle Growth in Human Study

Posted November 6, 2013

Natural betaine from DuPont Nutrition & Health improved the body composition, performance and power of strength-trained men who consumed the sugar beet extract every day over a six-week period. Betaine has been shown to improve body composition in several animal studies previously, but this is the first clinical study to demonstrate this benefit in humans.

Vitamin D Supplementation Increases Lower Limb Muscle Strength

Posted October 28, 2013

Vitamin D supplementation has a positive effect on global muscle strength; specifically, lower limb muscle strength, a meta-analysis presented at the 2013 ACR/ARHP Annual Meeting has found.

Researchers say supplement cuts muscle loss in knee replacements

Posted October 27, 2013

Twenty grams of essential amino acids taken twice daily for a week before and for two weeks after knee-replacement surgeries helped 16 patients, mean age 69, recover faster and with much less muscle atrophy than a control group ingesting a placebo.

Vitamin D may improve neural plasticity, muscle performance in aging adults

Posted October 11, 2013

Vitamin D may improve neural health and muscle performance, according to data presented at ASBMR 2013. Robin M. Daly, PhD, FASMF, professor and chair of exercise and aging at the Center for Physical Activity and Nutrition Research at Deakin University in Melbourne, Australia, said during a presentation, “Given that the nervous system sends signals to muscles to produce coordinated muscle contractions, we hypothesized that vitamin D perhaps has a vital role in enhancing muscle responses.”
