 Jason Boyle, Ph.DOur muscles are controlled by “motor units”, which each consist of a neuron, and the muscle fiber(s) it activates or “innervates”. The muscle that responds is termed an “effector”. Brain mapping studies have shown that a disproportionate area of the motor cortex governs certain effectors of the body. For example, your fingers, lips, and tongue are highly innervated organs that can execute complex movement patterns, but your toes are not ...

Sanjeev R. Bhatia, B.P.T.Human memory and the ability to recall vast amounts of trivia and unrelated information have intrigued scientists and researchers for quite some time. However, sometimes memory is inconsistent in its retrievability. Research on memory often focuses on “consolidation,” used here to refer to the organization of memory in the brain over time to make recollection more permanent and easily accessible. One technique is called chunking. Chunking is used in daily lif...

Chang Woock Lee, B.A.Cholesterol is perhaps the most notorious biological molecule of all. To many people, cholesterol is simply a synonym for heart attack, stroke, or cardiovascular disease because excessive blood cholesterol and lipid contributes to development of plaque build-up in the arteries and can eventually narrow and clog the blood vessels. Thus, cholesterol has become a nemesis to be overcome and destroyed. People try to eliminate cholesterol from their diet, and the media constantly ...

Priscila Caçola, Ph.DHave you ever wondered why a child learning to strike with a tennis racquet has trouble “finding” the ball? For adults, research shows that holding a racket or any tool that increases the ability of the body to reach further makes the brain recognize that tool as part of the “body schema.” The “body schema” is how we represent our body dimensions in our minds, so we can calculate distances and how we fit in the space surrounding us....

Jonathan Oliver, Ph.DDue to their intense training and physical abilities, athletes are assumed by many people to be healthy individuals. However, this may not always be the case. Studies have recently shown that football athletes, particularly linemen, are at an increased risk for the development of cardiovascular disease. This is evidenced by the increased morbidity rate of retired professional football players.  In fact, sport scientists have been researching younger ...

Vincent C.W. Chen, B.S.Metabolic syndrome, a condition including insulin resistance (causing diabetes), obesity, hyperlipidemia (high blood lipids), hypertension, and heart disease, is mainly due to high fat diets and lack of physical activity. It has become a major health concern in modern society. Recently, a substance called PPAR-delta has been identified as a potential therapeutic remedy for the treatment of metabolic syndrome. PPAR-delta is the most abundant isoform among the three PPARs (p...

Majid Koozehchian, M.S. In our bodies, oxygen constantly produces toxic substances called reactive oxygen species (ROS), also known as oxidants. Antioxidants, biomolecules that combat oxidant damage, are produced by the body and can also be taken in supplement form. Disruption of normal cellular function by ROS is termed oxidative stress, and can be considered an imbalance between ROS production and the body’s production of antioxidants, weighted on the oxidant side (Fig.1). Low level...

Emily Schmitt, Ph.D.Should I “Enhance” Athletic Performance with Dietary Products?This is one of the questions that constantly arise in the sports medicine and performance world. And to be honest, it is a difficult question to address. Researchers have studied diet manipulation for years in relation to delaying the onset of fatigue, and these studies have resulted in mixed conclusions. Scientific publications conclude that carbohydrate (products such as energy gels or ...
