Vincent C.W. Chen, B.S.When eating less to reduce weight, it is hard not to lose some muscle mass. During dieting, the body struggles to keep sufficient energy stores, and therefore, it will break down muscle proteins to satisfy energy needs. While the basic equation for muscle mass is rate of protein synthesis subtracted rate of protein breakdown, decrease in muscle size will be observed if muscle protein breakdown is not prevented while on a calorie-deficit diet.It has been well established th...

Kevin Shimkus, B.S.In muscle research, we tend to pay a great deal of attention to a particular signaling protein called mTOR, a key regulatory protein that signals for cell growth through the creation of new proteins. Consider protein building similar to a race car. The larger the engine, the greater potential for speed. Similarly, the more mTOR protein present in any given cell, the greater potential for more protein construction. And just like the gas pedal fuels the engine, mTOR is a signali...

The Chicken or The Egg?

The Chicken or The Egg?

Chang Woock Lee, B.A. The chicken or the egg? No, this is not about the famous causality dilemma of “which came first?” but rather about excellent sources of dietary protein. Eggs are a complete protein, provide protein digestibility similar to chicken, and are a good source of protein. Two large eggs (100 grams), according to USDA data, provide 12 grams of protein, while a chicken thigh (meat only, 52 grams) provides 13 grams of protein. However, eggs are much higher in an important...

Meredith Luttrell, Ph.DWe seldom think about physical effects of aging until that first wrinkle appears. While it’s easy to associate aging with changes in appearance, changes that occur within the body, such as impaired blood vessel function, are more likely to affect the quality of life even more. Cardiovascular disease affects 1 in 3 Americans, according to the Centers for Disease Control, and the risk of developing it increases with age. The term cardiovascular disease (CVD) encompasse...

Brad Lambert, Ph.D, CSCCA-SCCCFor optimal health and fitness, the American College of Sports Medicine recommends both resistance and endurance exercise regularly. Both forms of exercise provide specific benefits for one’s health. Endurance exercise such as jogging or biking has been found to increase aerobic fitness, reduce body fat, and aid in the prevention of a number of metabolic diseases. Resistance exercise is typically found to increase muscle mass, muscular strength, bone density, ...

Kaleigh Camp, M.S.Standing at the starting line of the 2011 San Antonio Rock ‘n’ Roll half marathon with over 30,000 other runners, it was clear how popular these races have become for athletes as well as non-athletes. Running USA, the track and field running information center, acknowledges the surge over the past quarter of a century. At the beginning of the race, salt packets were provided and passed around the population of runners. I wondered whether all runners understand the p...

Evelyn Yuen, M.S.In the condition known as osteoporosis, bones become weak and susceptible to fractures. This vulnerability results from low bone mass and structural deterioration of bone tissue. Although it primarily afflicts the elderly, it can develop at any age. Osteoporosis is a growing public health threat that affects 55 percent of people 50 years of age and older; approximately one in two women and one in four men over 50 years old will have an osteoporosis-related fracture in their rema...

William Kobbe, CPTU.S. Army Ranger A title like the one above usually produces immediate interest and often some skepticism, especially in the society of quick fixes but, at least in this case, isn’t misleading.  A course pioneered in the 1950’s in support of leadership development does just that -- shreds body fat.  To qualify for the program, a candidate needs to be a young, healthy male willing to undergo legendary hardships to graduate from the U.S Army Ranger Scho...

Samantha Springer, M.S., CSCSThe title’s quote was published by the Global Healing Center as a clever introduction to the health benefits of the infamous chia seeds.  Chia pets have been a popular novelty since the 1980s, but as science advances, health discoveries are gradually shifting the purpose of this herb away from garnishing a ceramic display. It is now being classified as a superfood that should be utilized by everyone; however, endurance athletes ought to especially consider...
