Caitlin Hendler, M.S.Most commonly known as the “Sunshine Vitamin,” the main source of this fat-soluble vitamin is exposure to sunlight because of few food sources. The benefits of vitamin D go much further than merely a bronze tan – studies show that it assists in growth, remodeling, regulation of calcium and phosphate concentrations for ideal bone health and physical performance. Vitamin D is a vital nutrient for optimal health in the general population but even more signific...

Vincent Chen, B.S When talking about resistance exercise, some people believe that women respond less than men in terms of muscle mass and strength gain, while others think that it may make women look bulky. Many women therefore tend to avoid doing resistance exercise. However, the benefits outweigh the possible drawback of bulkier appearance. Physical inactivity-induced muscle loss may reduce an individual's ability to resist impact and lower the basal metabolic rate (BMR) to an unheal...

Rachel Botchlett, M.S.Skeletal muscle is a highly specialized tissue that is responsible for voluntary motion and plays a significant role in glucose metabolism and maintaining postural support. The loss of skeletal muscle, defined as atrophy, is characterized by a marked reduction in muscle protein synthesis coupled with an increase in protein degradation and can lead to a loss of contractile force. Muscular atrophy can be caused by several health issues, including starvation, aging, and muscul...

Nina Laidlaw Rumler, B.A.Do you know what sport uses weights and is governed by rules published in 17 different languages with participants in 100 different countries, competes males and females of all ages and sizes against others in their divisions – and is not in the Olympics? Here’s a hint – it’s not bodybuilding although it maximizes muscle development; in fact, it developed in competition with bodybuilding. Although it uses weights, it isn’t Olympic weigh...

Jason Boyle, Ph.DOur nervous system is highly adaptable in perceiving, analyzing and executing movements in relation to an ever-changing perceptual environment. We use vision, knowledge of limb location, and anticipation of force production while simultaneously recognizing variability in our judgment to execute movements through the world around us. Whether it is simple (reaching for a door knob) or complex (threading a needle), goal directed movement has been repeatedly shown to follow a speed/...

Nina Laidlaw Rumler, B.A.This is Amuhrica, right? We power-through, man-up, and tough it out. Well, that’s not always a good strategy. We hear constantly about the benefits of physical activity but often overlook the drawbacks. While physical activity has positive effects in prevention or reduction of a number of illnesses (diabetes, hypertension, cardiovascular disease, osteoporosis, some types of cancer, etc.), there is also a strong association with injury. Some, such as spinal cord inj...

John Seawright, B.S.We’ve all seen it; the vicious collision that leaves a football wide receiver writhing in apparent pain; his strenuous, assisted walk to the locker room; and his eventual return to rejoin his team on the sideline with the accompanying statement from the sideline reporter, “The x-rays are negative.” X-rays are a form of high energy, ionizing radiation with a wave frequency much smaller than visible light on the electromagnetic spectrum. A medically ...

Andrew Jagim, Ph.D, CSCSIt makes sense right? It’s the day after a tough workout, you’re sore, it hurts to move but you have to move because you have another session with your trainer in two hours. So, what do you do? You pop some non-steroidal anti-inflammatories (NSAIDs) to take the edge off and get back out there for round 2! The question is: Is this doing more damage than good? It seems as though there has always been some controversy regarding the administration of NSAIDs. Are t...

Steve Bui, M.S.If you look at any advertising in the media, you will notice constant bombardment by ads for performance enhancing supplements. The supplement industry is one of the most lucrative marketing fields. The promise of being able to perform bigger, faster, and stronger by drinking some special water, swallowing a small pill, or anything in between just sounds so appealing. Unfortunately, unbeknownst to the majority of consumers, most supplements do not work at all. Supplements are desi...

Ann Amuta, MPH, CPHI always teased my obese friend, Molly, who grew up in the ‘hoods’ of Houston until she told me about her life’s journey to obesity and all the health complications that have ensued. My friend was poor, lived in a dangerous area, had to ride the bus to school because there were no safe paths to walk, and couldn’t afford healthy food so she ate fast food and whatever was served in the free school meals.  It is easy to blame Molly and say “why ...
