Read MoreThere are two types of diabetes and pre-diabetes as topics of interest. Type one diabetes is characterized by the destruction of the insulin-secreting B-cells of the pancreas. It can be characterized as an auto-immune disease. Type two diabetes is caused by the malfunction of the B-cells of the pancreas and the pathological condition where the cells fails to respond to insulin concentrations appropriately known as insulin resistance.

Read MoreHeat Acclimatization to Improve Athletic Performance in Warm-Hot Weather
This week’s article covers homeostasis and the constancy of the internal environment. Several natural phenomena can override even the most stable dynamic system. One of those phenomena is heat, particularly warm-hot weather. Homeostatic mechanisms are built in as control systems, allowing negative and positive feedback signals to either reduce the intensity of an affect and completely eliminate it, or to enhance an affect. (more…)
Read MoreResearch has long proven that one’s occupational activity level is closely related to health and mortality rates. For those whom sit at a desk all day, posture is only one aspect of physical health that suffers. The activity level required by an occupation has been researched for the negative or positive implications of increased or decreased activity requirements. (more…)
Read MoreRecently the brain and immune system have been tied into an intimate affair. The role of the immune system in relation to the brain gives way to explanations for autoimmune diseases and neurodegenerative diseases. Perhaps just as important are the disease defined by the DSM-IV. (more…)
Read MorePhysical activity is a therapeutic, medicinal strategy to combat the leading causes of death world-wide. Currently the top two leading causes of death world-wide (ischemic heart disease & stroke) out total the next eight leading causes of death combined (World Health Organization, 2014). One of the primary causes of ischemic heart disease and the most common form of stroke is atherosclerosis. (more…)
Read MoreObesity affects every continent on the planet. From the tip of the North Pole to the equator to the edge of the South Pole, it is prevalent. Humans are naturally wired to store fat. Our bodies have an unlimited capacity to store fuel into our adipose tissue. More and more adipocytes are able to be created. However, haven’t we gone far enough? (more…)
Read MoreSUMMARY
An increase in the prevalence of obesity in children under the age of five has arisen in both the developed and developing countries of the world. A multi-faceted intervention designed to improve the body composition and physical fitness of preschool children in China showed significant promise. (more…)
Read MoreHeart rate recovery is a prognostic tool in patients with heart failure. This study is the first of its kind aimed to identify whether heart rate response during and after the six-minute walking test provides significant prognostic insights. (more…)

Read MoreA link between physical activity and a reduced risk of cardiovascular disease exists. Whether the improvement is due to positive changes in lipoprotein profiles is undetermined. Using a prospective, randomized study design, researchers investigated the effects of the intensity and amount of exercise on lipoprotein profiles. The researchers gathered that the amount of exercise was the critical factor associated with improved lipoprotein profiles. (more…)
Read MoreWeiss et al. (2007) – weight regain
The skills necessary to prevent the backslide of weight regain are elusive and hard to pinpoint. Patients treated by lifestyle modifications generally regain 30% to 35% of their lost weight in the year after treatment and will regain the majority, if not all of the weight lost, within five years. Weight regain has been associated with fast food consumption, higher television viewing, and lower levels of physical activity. The objectives of this study were to determine the prevalence and predictors of weight regain in adults in the United States who had experienced substantial weight loss. (more…)
Read MoreAssociations between physical-activity and breast cancer has been reported before. Previous studies didn’t examine the risk of breast cancer for all types of physical activity (occupational, household, and recreational) for entire lifetimes, assessing all parameters of physical activity. The purpose of this study was to address the unanswered questions regarding the type and dose of activity and the time periods in life when physical activity may be specifically associated with breast cancer risk. (more…)
Read MoreThese articles focused on interventions aimed at adolescents. Both interventions measured predictors of physical activity fidelity. The study by Corder et al. focused on the desires of adolescents to increase physical activity. The study by Hall et al. measured process evaluation from the HEALTHY physical education intervention. Both studies paid attention to the barriers, fidelity to intervention, implementer’s participation, interventionist interviews, and class observations. (more…)
Read MoreThe public wants the truth. They will do what it takes to get it. However, public health and physical activity aren’t simple enough to learn what’s wrong or right in one or two days. Sometimes bad advice can live in the program of an individual for years until they realize it wasn’t as correct as they believed. It’s similar to the quote by Thomas Edison “I have not failed. I’ve just found 10,000 ways that won’t work.” Yes, that’s a positive outlook but I don’t think anyone has time to try a fitness technique or concept 10,000 times. The frustrating part is that an individual can try a new weight loss technique, or resistance training program and not know if it works for two-three weeks or longer! That’s one reason why bad science is dangerous for physical activity and public health. The other reasons are that the truth is hard to get a hold of. The internet is quick and convenient, and humanity is lazy by nature. We want the quick fix; the magic bullet. Most people will settle for an answer for free from the guy on the internet with fake credentials and no resources than to ask or pay the professor or expert in a field. The ironic part is that the free answer on the internet is almost always worth less than it costs.
