Cardiovascular / Circulatory
Body composition (BC) can be defined as the proportions of various tissues (i.e., fat, muscle, and bone) making up the body, which is generally expressed as percent body fat and percent lean body mass (Lee & Nieman, 2013). As such, knowing BC can help one track changes during weight loss or weight gain programs, in…
In my last post, I outlined factors that could contribute to cardiac arrest, as a first step in anticipating and managing weight room emergencies. In the following sections, I would like to build on the aforementioned early detection strategies by outlining a prevention and management program suggested by Abbott (2013). Abbott (2013) submitted that although…
Awareness and identification of liability exposures in a fitness facility is a central step in developing strategies for protecting clientele, and employees (Einkoff-Shemek & Deja, 2000). A common accident that occurs in fitness facilities is cardiac arrest, and some institutions still experience difficulties preventing and managing cardiovascular complications when it they do occur (Abbott, 2013)….
Anticipation and detection of cardiovascular heart disease (CHD) are paramount in its treatment. Understanding the degenerative process and risk factors of CHD helps shape our exercise choices and program development. I would like to cover contemporary research regarding benefits of exercise, in order to curtail the deleterious effects of CHD. Epidemiological evidence shows that physically…
Understanding the disease process of coronary heart disease (CHD) allows us to anticipate, detect and treat its dysfunction before CHD worsens. Epidemiology has assisted us by collating several biomarkers that filters out individuals at risk of CHD. The following will cover these risk factors in more depth, in an attempt to broaden our understanding of…
Pathophysiology helps us understand the pathology and physiology behind diseased and disordered systems of the body. In my last post, I covered roles of the cardiovascular system and the diseased states that occurred within it. Now, I would like to cover the pathophysiology behind these diseased states, as a precursor to anticipate, treat and prevent…
The cardiovascular system serves many important functions, and supports every other physiological system. The more positive adaptation the cardiovascular system experiences, the more proficient it can fulfill its roles. Conversely, a diseased cardiovascular system will hinder all other physiological processes. I would like to briefly review the functions of the cardiovascular system, look deeper into…
In my previous posts, I outlined how hot and humid climates increase the rate of dehydration during exercise. I also provided strategies to maintain proper fluid balance in these conditions. I would now like to explore the concept of heat acclimation and methods to overcome and adapt to hot environments. Heat acclimation can be defined…
Hypertension is a significant public health concern, in which its reach extends internationally (RamBihariLal Shrivastava, Saurabh Shrivastava, & Ramasamy, 2014). Considered the most common cardiovascular disease risk factor, more than 23 million cardiovascular deaths are estimated to occur by the year 2030, due to hypertension (RamBihariLal Shrivastava et al., 2014). Complications related to hypertension include…
Roberg and Landwehr (2002) indicated the ambiguous history, poor predictability, and misuse of the maximum heart rate prediction equation (HRmax=220-age) commonly taught and used in academic institutions. Unveiling the aforementioned truths is a reminder that dogmatic practices can insidiously permeate throughout a field in an unknown, and undetected fashion. Considering the lack of scientific merit…
