Kyle Levers, MS, CSCSStrength and power athletes are a unique athlete subset, which includes many different types of athletes and can span highly varied requirements for strength and power development.  The difference in strength and power requirements stems from different physiological, anatomical, biochemical, and energy system requirements by various sports.  However, all strength and power athletes rely on development of maximal force within the muscle (potentially at a h...

Dr. Deepesh KhannaHeart rate variability (HRV) means changes in the interval or distance between one beat of the heart and the next (1). It has relevance for physical, emotional, and mental function. The human heart is a bio-electrical pump beating at an ever changing rate. This variability in heart rate is an adaptive quality in a healthy body. HRV is controlled by the autonomic nervous system, which is comprised of sympathetic and parasympathetic components. It has been elucidated that alterat...

Mitochondria and Cardiac Aging

Yang Lee, M.S.Oxidative damage, which is the accumulation of reactive oxygen species (ROS) in cells, affects the aging process, and old age is a major risk factor for cardiovascular diseases. This phenomenon is well explained by “The Oxidative Stress Theory of Aging”, which explains that the life span of an organism is determined by the age-related loss of physiological function by the progressive cumulating of oxidative damage. This theory has been modified to “The Mitochondri...

 Jeffrey Hord, B.S.Skeletal muscles come in a variety of sizes and shapes so that they suit the particular function that they perform. Some of these muscles work virtually all of the time while others are necessary only part of the time. Locomotor muscles that help us physically move our bodies are not as essential as our hearts or other vital organs but they are crucial for us to go about our everyday activities. Our skeletal muscles have matured and essentially been trained to function in...

DEPTOR: New Kid on the Block

Will Deaver,  M.S.The DEP domain containing mTOR-interacting protein, or DEPTOR, is a relatively new protein that our lab has focused on for its potential roles in muscle physiology. DEPTOR is a negative regulator of mTOR, a keystone protein responsible for muscle protein synthesis and cell growth. Essentially, mTOR signals for muscle growth. DEPTOR is a negative inhibitor of mTOR, and high levels of DEPTOR prevent mTOR signaling and result in lower muscle masses.Recently, our lab published...

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...

John Seawright, B.S.For men, the probability of developing cancer at some point in life is equivalent to flipping a coin; 1 in 2; for women, it’s slightly better at 1 in 3. Take a coin out of your drawer and think of your father. Now, flip the coin. Let’s do it again. This time, think of your brother, your son, or yourself. At some juncture in your life, the phrase “I’m going to refer you to Oncology,” is likely to cross your road. Robert Frost had something to say ...

Jiling Liu, M. EdEffective teaching (ET) in physical education (PE) happens when students have positive changes in thinking, behavior, and emotion. These changes can result in more positive attitudes toward learning motor skills, more active participation in PE classes, and/or improvement in PE grades. Research shows that what teachers understand affects how they teach. In order to teach effectively, teachers should fully understand what ET means and what constitutes ET. For this reason, physica...
