Skeletal Muscle Pump Drives Control of Cardiovascular and Postural Systems
The causal interaction between cardio-postural-musculoskeletal systems is critical in maintaining postural stability under orthostatic challenge. The absence or reduction of such interactions could lead to fainting and falls often experienced by elderly individuals. The causal relationship between systolic blood pressure (SBP), calf electromyography (EMG), and resultant center of pressure (COPr...
متن کاملPeripheral Arterial and Venous Response to Tilt Test after a 60-Day Bedrest with and without Countermeasures (ES-IBREP)
UNLABELLED We quantified the impact of 60-day head-down bed rest (HDBR) with countermeasures on arterial and venous response to tilt. METHODS Twenty-one males: 7 control (Con), 7 resistive vibration exercise (RVE) and 7 Chinese herb (Herb) were assessed. Subjects were identified as finisher (F) or non-finishers (NF) at the post-HDBR 20-min tilt test. The cerebral (MCA), femoral (FEM) arterial...
متن کامل[Cardio-Pulmonary-Renal interactions].
Over the past decade, understanding about feedback mechanisms involving the heart, lung and kidney is significantly improved. Each organ injury may trigger hemodynamic, neuro-hormonal and cellular pathway that may damage diverse organs. Recurrent acute on chronic injury may lead to the advanced stage of disease. On the other hand, chronic pathological conditions may decrease functional reserve ...
متن کاملAre Heart Muscle Irisin Levels and FNDC5 Gene Expression Regulated by Endurance and Resistance Exercises?
Background. Irisin is the result of the proteolysis of fibronectin type III domain-containing protein 5, the levels of which are determined by physical activity. Objective(s). This study aims to identify changes in FNDC5 gene expression and the heart muscle irisin levels in male rats following 8 weeks resistance and endurance training. Methods. Fifteen male rats (10-12 weeks old and 331.8&plu...
متن کاملEffects of Exercise and Nutrition on the Coagulation System During Bedrest Immobilization
Immobilization in hospitalized medical patients or during simulation of spaceflight induced deconditioning has been shown to be associated with loss of muscle mass and bone. Resistance vibrating exercise (RVE) and/or high protein diet are countermeasures, which are capable of mitigating the adverse effects of immobilization. We investigated the effect of these countermeasures on the coagulation...
