The Magical Farce of Negative Calories, The Thermic Effect, and Resting Energy Expenditure
by EricT on 10 May 2012 21:17
Turning over a new leaf, just for this post, at least, I decided to actually write about fat loss. People who read my articles regularly know that I do not hand out weight loss advice. But a fun subject, and one a knowledgeable feller like myself can tackle, is the "negative calorie" claim that has surfaced through the years. The thing about this claim is that it can seem logical at first glance, to someone with no in-depth knowledge of nutrition, and at the heart of it, there is a kernel of truth. For those without knowledge and those who wish to cash in on that market, a kernel of truth is all that is needed….
Ergolytic Agents: Substances and Other Agents that Impair Performance
by EricT on 09 May 2012 01:23
Ergolytic is the opposite of ergogenic. It is derived from the Greek word, ergon, meaning "work" and -lytic, which is the adjective form of the Greek word lysos, meaning "loosing, dissolving, or dissolution." The term ergolytic is used to refer to an agent, device, or factor that impairs athletic performance rather than enhances it. This impairment can be the result of physiological or psychological factors. Some common ergolytic agents are alcohol, tobacco (including smokeless), and marijuana….
Soda Loading (Bicarbonate Loading, Buffer Boosting) for High Intensity Anaerobic Endurance
by EricT on 07 May 2012 17:30
During high intensity anaerobic events, the muscles fatigue and energy supply is compromised because of the buildup of lactic acid from glycolysis. Athletes in high intensity events that last 2 to 10 minutes, such as a 400 to 800 or 1500 meter running races or middle distance swimming races sometimes use soda loading in an attempt to neutralize the lactic acid that accumulates in the blood. Depending on interpretation of the research, some experts suggest that the benefit is limited to events of 1 to 7 minute duration. Soda loading is also called buffer boosting or bicarbonate loading. It is also called, more rarely, soda doping or simply acid buffering….
Double Progressive System
by EricT on 07 May 2012 14:13
The Double Progressive System is a resistance training method that attempts to vary the stimulus by changing the number of repetitions and the resistance used. At first the resistance is kept the same and the number of repetitions is increased with each consecutive workout, until a certain per-arranged number of reps is reached. At this point, various scenarios are given as to how to continue, but all of them involve decreasing the reps and increasing the resistance. A common scenario would have the lifter simply increase the load by 5% and reduce the number of reps back down to the initial low starting point, and then repeating the process….
Anorexia Nervosa: Explanation, Signs, and Symptoms
by EricT on 02 May 2012 16:08
The term anorexia nervosa comes from the Greek word for "lack of appetite" and a Latin word implying a nervous origin. It is a major emotional eating disorder and is characterized by three main criteria:
- Significant self-induced starvation, or near-starvation
- An extreme desire for thinness or being extremely afraid of becoming fat
- The presence of medical signs and symptoms resulting from starvation…
Peformance Enhancing Drugs Other Than Anabolic Steroids Used in Sports
by EricT on 24 Apr 2012 15:43
Although most people, when they think of "performance enhancing drugs," only think of anabolic steroids, there is actually a large array of drugs that are used to enhance various aspects of performance. Some basic categories of drugs that are used in this way, including steroids, are stimulants, beta blockers, beta-2 agonists, diuretics, narcotic analgesics, and the oxygen increasing drug epoetin.
Since all such drugs are meant to be prescribed and used for specific medical conditions, using them as ergogenic aids can be very dangerous and such use should be considered abuse. This is especially true since athletes often take drugs in doses that far exceed normal therapeutic doses, and side effects, in some drugs, can occur even at normal levels. The side effects of a drug may also depend on the person's metabolism and whether other drugs are used at the same time. The following is a list of categories of performance enhancing drugs, their intended effect on performance, and their potential side-effects, starting with a brief review of anabolic steroids….
