Jing Chen, Ph.D.Aerobic exercise can help motor skill learning by protecting previously learned procedural memory from subsequent interference tasks (for example, subsequent declarative memory). The primary motor cortex may play an important role during this process. When we examine this has happened, we will perform three experiments to see if our hypothesis is true. In the first two experiments, we let participants perform procedural memory immediately followed by declarative memory or a ...

Caitlin Ballard, M.S.Finland is a world leader in education and health outcomes, ranking 8th among 50 countries in childhood and youth fitness levels. In comparison, the United States ranked 47th in the same study. Finland is consistently recognized as one of the most top performing countries in the world. Additionally, Finland provides equal opportunity to higher education, innovative teaching methodologies, high quality curriculum, and advanced pedagogy strategies to keep students active and e...

Anita Mantri, B.S.Since the introduction of “the pill,” its use as a form of birth control and contraception has steadily increased in women of child-bearing age as seen in reports from the CDC. When the pill first came out in the 1970s, its use was very limited out of caution about the unknown effects of adding extra hormones to the body. Usually, the hormones estrogen and progesterone have distinct cycling patterns that prepare a woman’s body for pregnancy and lead to her per...

Jacqueline I. Perticone, B.S.Loss of muscle mass with advancing age, disease or lifestyle has a profound influence on healthcare and society. Our laboratory uses hindlimb suspension in rodents to better understand loss of muscle mass occurring with disuse in an effort to design specific interventions that may be suitable to maintain muscle health and function in a number of populations. It is well-known that loss of muscle mass with reduced activity results from a slowdown in the muscle’s ...

Using Chains May Improve Your Strength and Conditioning

Using Chains May Improve Your Strength and Conditioning

Majid Koozehchian, M.S.In recent years, strength training with unconventional objects has become popular (1). One unconventional method that has gained recognition by elite athletes is adding chains to the end of conventional barbells. There are many claims that this type of training can improve strength and power above those achieved by traditional free weights (2). In addition, chain-loaded resistance training is also believed to reduce joint stress resistance training during exercises such as...

Seung Kim, M.S.Do you exercise regularly? If so, what benefits do you expect from exercise? Ever wonder whether you’re exercising in appropriate ways? Except for few people who are addicted to exercise, the main reason most people spend time and money for exercise is to maintain/improve their health. In general, the benefits of exercise include health-related risk factor reduction, anti-aging effects, prevention/improvement of disease, etc.However, there are things to carefully consider re...

Josh Avila, M.S.People like to place the blame on their genes for their lack of Herculean strength or Olympic endurance. But is this really fair? Do our genes actually have an effect on our ability to exercise?Improvements in cardio-respiratory fitness made by increasing levels of physical activity have been shown to reduce the level of all-cause mortality regardless of baseline fitness levels. Research has shown that both initial exercise capacity and the response to exercise training are highl...

Don't Want to Lose Muscle Mass While Dieting? Take BCAAs!

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...

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...
