Ramon Boudreaux, M.S.It is often joked that if exercise could be given as a pill it would be the most prescribed drug in the world.  While some benefits of exercise are well known (e.g., the prevention of heart disease, high blood pressure, and obesity), some remain esoteric. Osteoporosis, a condition in which bones lose density by an increase in porosity, is one such example.  Low density bones are at a much higher risk of fracture.  If one were to compare the architecture of a b...

Yang Lee, M.S.Heart cells (myocytes) have distinctive shapes, structural integrity, and functions that are maintained by proteins that are part of the “cytoskeleton”. The cytoskeleton is scaffolding or framework around the cells serves to stabilize cells and tissues and regulate internal function of the cells. The dystrophin-glycoprotein complex (DGC) is a structure comprised of proteins on the outer side of the cell membrane that links the cell and its cytoskeleton to the connective...

Kyle Levers, M.S., CSCS While sports performance and training have become increasingly competitive and demanding, recovery techniques continues to rely on existing therapies.  Many athletes find water therapies helpful to hasten the recovery process in order to return to bouts of exercise sooner, while minimizing fatigue and injury.Two of the most common water immersion therapy techniques used in the recovery from fatiguing exercise are cold water immersion (cryotherapy) and contrast w...

Majid Koozehchian, M.S.Vitamin C is a water soluble vitamin, and thus our body does not retain it in large amounts. It is a strong antioxidant that has a key role in protecting against oxidative damage and tissue trauma. Vitamin C can neutralize potentially harmful reactions in the watery parts of our body, such as blood and the fluid inside and surrounding cells. It is one of the vitamins that many athletes consume in rather substantial amounts; therefore they are more familiar with i...

Andrew Jagim, Ph.D, CSCSTo unlock better performance, consider the humble beverage water. It is often one of the most overlooked and underappreciated ergogenic aids in today’s world of sports. The body is made up of ~70% water, which makes hydration a vital component for success-- not only during but before and after exercise as well. Dehydration can limit performance without the proper precautions, especially in hot and humid environments. Sweat is the primary means by which body water is...

Andrew Jagim, Ph.D, CSCS  Juice, roids, gym candy, pumpers and stackers are all common nicknames for substances more technically referred to as anabolic-androgenic steroids.  Anabolic steroids are defined as any type of exogenous drug that mimics the effects of testosterone in the body.  Most people take them with the goal of increasing muscle mass, improving performance or enhancing physical appearance.  It is estimated that as many as 3 million Americans have used non-medic...

Andrew Jagim Ph.D, CSCSRunners, cyclists, and other endurance athletes are constantly looking for ways to improve their performance.  A commonly used strategy is the use of nutritional supplements to “boost” energy and enable them to perform longer and or harder before fatigue sets in.  The majority of energy used during endurance events is derived from carbohydrates.  Carbohydrates can be stored in the liver and skeletal muscle as glycogen.  When exercise lasts l...

Brandon Macias, Ph.DMost folks, especially those who do not suffer from bone debilitating diseases, might forget that their skeletons are “alive.”  Yes, the bone that protects your vital organs and works with your muscles to get you out of bed in the morning is constantly remodeling.  Bone cells called osteoblasts lay down new bone matrix, and bone cells called osteoclasts, “eat” or resorb bone tissue.  In a normal healthy human, this bone-forming activity ...

Majid Koozehchian, M.S.Homocysteine (Hcy) is a non-proteinogenic amino acid (i.e., an amino acid not used in proteins) normally present in the blood. Hcy is a by-product of normal diet but high levels in the blood can endanger cardiovascular health. It is formed from methionine, a proteinogenic amino acid, and can biosynthesize back to methionine or into cysteine, another proteinogenic amino acid, as well as several other substances. Benefits of Hcy are unknown; however, its harmful effects...

Brad S. Lambert, Ph.D, CSCCA-SCCCHas there ever been a time when you decided to begin an exercise program or turn your current exercise program up a notch with an increase in workout time or intensity? Also, have you ever experienced prolonged muscle soreness days after doing so? If so, you have probably experienced delayed onset muscle soreness. Delayed onset muscle soreness (DOMS) is a phenomenon that often arises at the beginning of a new exercise training regimen or if the int...
