Comparison Of Body Composition Prediction Equations With Air Displacement Plethysmography In Overweight And Obese Caucasian Males., Carley A. Shannon, Justin R. Brown, Andrew T. Del Pozzi

International Journal of Exercise Science

Body mass index (BMI) has been used for years by clinicians to approximate total body fat. However, the body adiposity index (BAI), body adiposity index from the FELS longitudinal study (BAIFELS), and an equation developed by Deurenberg et al. (BFD) were created recently to offset BMI’s limitations and accurately estimate percent body fat (%BF). The prevalence of overweight and obese Caucasian men is increasing in the United States; currently, there is no established way to quickly and accurately predict their %BF. Purpose: To compare the existing %BF equations (BAI, BAIFELS, and BFD) to measured %BF via air displacement plethysmography (ADP) …

Comparing Suicide Risk, Acquired Capability, Distress Tolerance, And Reasons For Living In Those With Non-Suicidal Self-Injury Or Disordered Eating, Brooke Beck

Student/Alumni Personal Papers

Acquired Capability has been a longstanding measure used to predict the likelihood that one may attempt suicide. However, does it hold true in every scenario? Are there other measures that would prove more accurate? This research evaluated these questions, examining archival data of two identified risk groups: those participating in Non-Suicidal Self-Injury (NSSI) and Disordered Eating (DE).

When measured using the Acquired Capability for Suicide Scale (ACSS), both groups have similar results in survey data as well as when measuring Distress Tolerance. This would imply that both are at the same risk of attempting suicide. However, when the groups were …

International Journal of Exercise Science

International Journal of Exercise Science 12(2): 786-799, 2019. This study examined glucose and lipid marker responses following a 3-week, ad libitum low-carbohydrate-high-fat diet (LCHF; ~70% kcals from fat, <50 g/day of net carbohydrates) versus the habitual mixed macronutrient diet (HMD) of eight middle-age, trained male runners (40 ±10 years; V̇O₂peak = 49 ±4 mL·kg^-1·min^-1). Blood was drawn at 0600 from an antecubital vein after an overnight fast under conditions of no exercise/ heat stress (NEXH; 48 h of restriction from intense exercise) or 24-h after exercise/heat stress (EXH; 60 min run in hot conditions plus 5-km time trial) for both dietary conditions. Glucose improvement during LCHF approached but did not reach statistical significance (p = 0.07). …

Too Much Workplace Sitting: A Brief Historical Perspective, Raymond Jones, Daniel P. Credeur, Stephanie M. Mccoy

International Journal of Exercise Science

International Journal of Exercise Science 12(2): 777-785, 2019. Sedentary behavior is a risk factor for the development of chronic diseases, especially those of cardiovascular and metabolic origins. Prolonged sitting is one of the most common sedentary behaviors among adults. Individuals sit for hours every day for several reasons, including work and or physical limitations. Historical accounts regarding the negative health effects of prolonged sitting began with early epidemiological studies, which sparked a breakout of research examining this behavior in the workplace setting. Understanding the risks associated with prolonged workplace sitting is important when considering workplace interventions, such as sit-stand workstations. …
