The purpose of this study was to examine differences in pressor response and cardiovagal modulation during isometric handgrip exercise (IHG) between children and adults. Beat-to-beat heart rate (HR) and blood pressure were measured in 23 prepubertal children and 23 adults at baseline and during IHG. Cardiovagal modulation was quantified by analysis of HR variability. Mean arterial pressure resp...

Femur fracture is a in the largest bone body. The femur requires significant force to fracture. One of treatments for femoral reduction and immobilization using traction. Immobilization traction-attached patients before preoperatively isometric exercises maintain muscle strength. Isometric exercise contraction exercise, patient contracts muscles without moving prevent atrophy. purpose this pape...

Automatic dysfunction may contribute to the hemodynamic disturbances in cirrhosis. Tests of autonomic function were performed in 31 patients with non-alcoholic cirrhosis and 30 healthy subjects. Patients were divided into 3 groups according to child- Pugh,s classification ( A.B.C). The patients with moderate and severe cirrhosis( child B,C) had significant parasympathetic disturbance ( in the v...

Hemodynamic and left ventricular systolic function were studied by Doppler echocardiography in 14 young and 15 older adult hypertensive patients and in 15 young and 12 older normotensive individuals. Measures were made at rest and during upright deadlift isometric exercise, at 30% of maximum voluntary contraction for 3 min. At rest, young and older hypertensive patients demonstrated impaired le...

Objective To investigate the feasibility and effectiveness of a home-based exercise program in TSP/HAM individuals. Methods Twenty-three TSP/HAM individuals divided in two groups according to Timed Up and Go (TUG) score (<20s vs ≥20s) performed a 20-week home-based exercise program. The primary outcomes were exercise adherence, maximum voluntary isometric contraction of lower limbs (MVIC), Ba...

The aim of the present study was to evaluate the use MRI to quantify the workload of gluteus medius (GM), vastus medialis (VM) and vastus lateralis (VL) muscles in different types of squat exercises. Fourteen female volunteers were evaluated, average age of 22 ± 2 years, sedentary, without clinical symptoms, and without history of previous lower limb injuries. Quantitative MRI was used to analy...

conclusions a short-term wbv exercise improves isotonic strength of the leg muscle and dynamic balance, while creatine supplementation with and without wbv training increases isometric strength of the leg muscle and mobility in elderly women. background a decline in neuromuscular function can cause a decrease in physical fitness in elderly women. objective the present study aimed at investigati...
