Body Composition, Muscular Strength, Arterial Stiffness, And Hemodynamics Responses To Various Training Protocols In Young Males, Jorge Bejar
Theses and Dissertations
PURPOSE: The purpose of this study was to compare the effects of 8 weeks performing various resistance training protocols with and without blood flow restriction (BFR) on muscular strength, body composition, arterial elasticity, and hemodynamics responses in young males.
RESULTS: Significant time*condition interactions occurred in HR period (p <0.05), HDI SBP (p <0.05), HDI MAP (p <0.05), and SV (p <0.05). Trends for time*condition interactions were found in HDI DBP (p=0.054), HDI HR (p=0.051), and HDI SVR (p=0.085). Significant time main effects occurred in all strength measures (p <0.05). Significant condition main effects occurred in Aortic DBP (p <0.05), Brachial DBP (p <0.05), and LAE (p <0.05). Total lean mass significantly increased from baseline the HI condition only (p<0.05).
CONCLUSION: Significant improvements in lean mass were seen following the HI and BFR protocols. However, decreases in LAE were found following the HI protocol only. It appears that performing aerobic exercise after resistance training can negatively affect muscle growth. However, only 15 min of moderate-intensity aerobic training can improve hemodynamics in young, …
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
Neuromuscular And Arterial Compliance Responses To Different Resistance Training Frequencies And Protocols, Patrick Murphy
Neuromuscular And Arterial Compliance Responses To Different Resistance Training Frequencies And Protocols, Patrick Murphy
Theses and Dissertations
PURPOSE: The purpose of this study was to determine the impact of blood flow restriction and resistance training on arterial elasticity, EMG activity, and strength indices among sedentary to recreationally active females who completed 6 weeks of resistance training.
RESULTS: Significant time*condition interactions occurred in LE-1RM (p
CONCLUSION: The research group(s), 1–2 days/week with and without blood flow restriction, may increase training adaptations and responses parallel to the control group (3 days/week). There appears to be no differences in arterial compliance between groups.
The Acute Effects Of Aerobic Exercise With Blood Flow Restriction Cuffs On Arterial Compliance In Males And Females, Maria M. Gonzalez
The Acute Effects Of Aerobic Exercise With Blood Flow Restriction Cuffs On Arterial Compliance In Males And Females, Maria M. Gonzalez
Theses and Dissertations
RESULTS: Significant condition*gender interactions found in in SBP (p<.05), PR (p<.01), SVR (p<.01), SpO2 (p<.05), PWV carotid to femoral (p<.03), and PWV femoral to distal (p<.02). Significant condition*time interactions were found in SBP (p<.01), DBP (p<.01), MAP (p<.01), SV (p<.01), CO (p<.01), SVR (p<.01), TVI (p<.01), HR (p<.01), and SAE (p<.01). Significant condition main effects were found in SBP (p<.02), DBP (p<.03), PR (p<.03), SV (p<.01), CO (p=.01), SVR (p<.01), TVI (p<.01), HR (p<.01), and SAE (p<.03) as well as a condition trend in PWV femoral to distal (p=.06). Significant time main effects were found in SBP (p<.01), MAP (p<.04), PP (p<.01), PR (p<.01), CO (p<.01), SVR (p<.01), TVI (p<.01), HR (p<.01), SpO2 (p<.01), LAE (p<.03), and PWV femoral to distal (p<.01).
CONCLUSION: The 60 min session at a moderate aerobic intensity might have the potential to improve arterial elasticity more than a 20 min BFR session.
