Are The Metabolic Benefits Of Resistance Training In Type 2 Diabetes Linked To Improvements In Adipose Tissue Microvascular Blood Flow?, Donghua Hu, Ryan D. Russell, Devika Remash, Timothy Greenaway, Stephen Rattigan, Kathryn A. Squibb, Graeme Jones, Renee M. Ross, Christian K. Roberts, Dino Premilovac

Health & Human Performance Faculty Publications

The microcirculation in adipose tissue is markedly impaired in type 2 diabetes (T2D). Resistance training (RT) often increases muscle mass and promotes a favorable metabolic profile in people with T2D, even in the absence of fat loss. Whether the metabolic benefits of RT in T2D are linked to improvements in adipose tissue microvascular blood flow is unknown. Eighteen sedentary people with T2D (7 women/11 men, 52 ± 7 yr) completed 6 wk of RT. Before and after RT, overnight-fasted participants had blood sampled for clinical chemistries (glucose, insulin, lipids, HbA1c, and proinflammatory markers) and underwent an oral glucose challenge (OGC; …

The Acute Effects Of Resistance Exercise With Blood Flow Restriction Versus Traditional Resistance Exercise On Arterial Compliance And Energy Expenditure In Recreationally Active Males And Females, Danny D. Dominguez

Theses and Dissertations

PURPOSE: The aim of this study was to investigate the acute effects of various intensities of volume matched resistance exercise with blood flow restriction (BFR) and traditional resistance exercise on hemodynamic variables, arterial compliance, oxygen consumption (VO2), carbon dioxide production (VCO2), respiratory exchange ratio (RER), and energy expenditure (EE) during exercise and after exercise.

RESULTS: Significant condition main effects (p < 0.05) were found for RPE, HR, crPWV, fdPWV, LAE, SAE, TVI, RER during and postexercise. BFR25 cause greater increases in RPE and HR. BFR50 caused marked increases in SAE, crPWV, and fdPWV.

CONCLUSION: All BFR and traditional exercise conditions found no significant differences in EE, VCO2, and VO2. The lack of differences is likely due to time of protocol. Further protocols should implement greater time of exercise, as BFR had increased hemodynamic …

The Effects Of A Short-Term Endurance Training Program With Blood Flow Restriction Cuffs Versus Acsm Recommended Endurance Training On Arterial Compliance And Muscular Adaptations In Recreationally Active Males, Brittany N. Esparza

Theses and Dissertations

RESULTS: Significant time and group interaction found in cardiac ejection time (p<.05). Significant condition difference between blood flow restriction (BFR) and control for heart rate (HR) max (p=.05) and maximum oxygen consumption (VO2) (p<.05). Significant time difference found in pulse wave velocity femoral to distal (p<.05). Significant repetition main effect (p<.01) for root mean square (RMS) and median frequency (MDF) of Thorstensson. Significant time and group interaction in vastus lateralis of MDF (p<.01). Significant repetition main effect for RMS and MDF ratio (p<.01) Significant time and repetition interaction in vastus lateralis of RMS ratio (p<.03)

CONCLUSION: The BFR session showed improvement in both post HR max and post VO2 in comparison to the control group. This may have been caused by increased tolerance to pain/metabolic by-products for HR and increased efficiency at extracting oxygen for VO2

Regulation Of Microvascular Flow And Metabolism: An Overview, Michelle A. Keske, Renee M. Dwyer, Ryan D. Russell, Sarah J. Blackwood, Aascha A. Brown, Donghua Hu, Dino Premilovac, Stephen M. Richards, Stephen Rattigan

Health & Human Performance Faculty Publications

Skeletal muscle is an important site for insulin to regulate blood glucose levels. It is estimated that skeletal muscle is responsible for ~80% of insulin-mediated glucose disposal in the post-prandial period. The classical action of insulin to increase muscle glucose uptake involves insulin binding to insulin receptors on myocytes to stimulate glucose transporter 4 (GLUT 4) translocation to the cell surface membrane, enhancing glucose uptake. However, an additional role of insulin that is often under-appreciated is its action to increase muscle perfusion thereby improving insulin and glucose delivery to myocytes. Either of these responses (myocyte and/or vascular) may be impaired …

Organization and School Leadership Faculty Publications

This article examines the exercise practices of a group of faculty members at a regional university who for a decade have participated in their own racquetball league. These professors self-organized their exercise regimen and during the period of their participation have found significant benefits beyond the physical benefits, as a result. Through the production of reflective narratives focused on the impact of their racquetball participation, their self-reported data show two broad themes and numerous sub-themes that emerge from their exercise experience. They reveal significant health benefits, and they express more deeply the benefits of the positive social interaction that impacts …

Age Comparisons Of Bone Density And Geometry In Men, Vanessa D. Sherk, Murat Karabulut, Michael G. Bemben, Debra A. Bemben

Health & Human Performance Faculty Publications

Objectives: The purposes of this study were to examine tibia bone density and geometry in young and middle aged men, and to explore relationships between pQCT- and DXA-derived body composition variables.

Methods: Healthy males (18-30 years old, n=31; 50-64 years old, n=37) had their total body areal bone mineral density (aBMD) and body composition measured with Dual Energy X-ray Absorptiometry (DXA). Volumetric bone characteristics, muscle cross-sectional area (MCSA) and fat cross-sectional area (FCSA) of the leg were measured with peripheral Quantitative Computed Tomography (pQCT).

Results: Young men were significantly (p<0.05) lighter and had less fat mass than older men. Total volumetric BMD (vBMD) at 66% of the tibia length was significantly lower (p<0.05) in older men. Bone-free lean body mass values were useful predictors of total and cortical area and content (R(2)=0.338-0.467). MCSA was more predictive of leg BFLBM than total body BFLBM, and those relationships were stronger in older men.

Conclusions: Differences in tibial bone area and density existed between …
