Individuality of responses to bilateral and unilateral volume equated hypertrophic strength training in physically active men
2019
Purpose. The purpose of the present study was to investigate possible differences between unilateral and bilateral strength training during ten weeks progressive hypertrophic strength training and six weeks detraining period. Furthermore, it was examined possible different individual responders in muscle hypertrophy during strength training and, how those different responders would behave during the detraining phase following the training period. Methods. The present intervention included ten weeks of progressive hypertrophic resistance training followed by six weeks of detraining in healthy young men (n=24). Ultrasound was used to measure vastus lateralis (VL) muscle cross-sectional area (…
Isometric force-time parameters in monitoring of strength training : with special reference to acute responses to different loading resistances
2017
The aim of the present series of studies was to investigate acute neuromuscular responses to (1) different strength training loadings and using (2) different external resistances. In addition, chronic adaptations and dynamic performances were compared to (3) the changes in isometric force-time parameters at the group level, and to (4) the individual timing of the improvement in the rate of force development (RFD) due to hypertrophic or maximum strength followed by power strength training periods. The latter one was achieved by systematic, repeated monitoring. Sixty-nine physically active men (20-35 yrs), but not experienced in resistance training, took part in the present series of studies.…
Electrocardiographic Indices of Left Ventricular Hypertrophy and Repolarization Phase Share the Same Genetic Influences: A Twin Study
2009
Background: Both left ventricular hypertrophy (LVH) and repolarization phase (RP) are known to be attributable to genetic influences, but less is known whether they share same genetic influences. The aim of this study was to investigate to what extent individual differences in electrocardiographic (ECG) LVH and RP are explained by genetic and environmental influences and whether these influences are shared between these two traits. Methods: Resting ECG recordings were obtained from 186 monozygotic and 203 dizygotic female twin individuals, aged 63 to 76 years. Latent factors, called LVH and RP, were formed to condense the information obtained from LVH indices (Cornell voltage and Cornell pr…
Cardiorenal syndrome type 4: From chronic kidney disease to cardiovascular impairment
2016
Cardiorenal syndrome type 4 (CRS type 4), or chronic renocardiac syndrome, has been defined as "chronic abnormalities in renal function leading to cardiac disease" and recognizes the extreme burden of cardiovascular disease (CVD) risk in patients with chronic kidney disease (CKD). CKD is common and increasingly recognized as a risk factor for CVD. Even though the treatment for CVD has dramatically improved over the past decades, it still takes responsibility for up to 50% of deaths in CKD patients. For this reason, patients with CKD should be thoroughly evaluated for cardiovascular risk factors that require careful management, given the significant burden of CRS type 4 on the healthcare sys…
Effects of soluble milk protein or casein supplementation on muscle fatigue following resistance training program: a randomized, double-blind, and pl…
2014
International audience; Background: The effects of protein supplementation on muscle thickness, strength and fatigue seem largely dependent on its composition. The current study compared the effects of soluble milk protein, micellar casein, and a placebo on strength and fatigue during and after a resistance training program. Methods: Sixty-eight physically active men participated in this randomized controlled trial and underwent 10 weeks of lower-body resistance training. Participants were randomly assigned to the Placebo (PLA), Soluble Milk Protein (SMP, with fast digestion rate) or Micellar Casein (MC, with slow digestion rate) group. During the 10-week training period, participants were …
Effect of Physical Training on Enzyme Activities of Bones, Tendons and Skeletal Muscles in Mice
1975
According to several recent papers the activity of some enzymes of energy yielding metabolic pathways increases by endurance training in muscles, but it is not yet known whether similar changes occur also in connective tissues. Some structural, chemical, physical and metabolic changes, however, appear in connective tissues during adaptation to physical exercise. Physical training produces hypertrophy of e.g. tendon and articular cartilage in young rabbits [6] and increases the tensile strength of tendons and breaking strength of bones in growing mice [7]. The level of physical activity affects the turnover of collagen in long bones and Achilles tendons of mice [4] and also affects the miner…
Esophageal achalasia and hypertrophic pyloric stenosis associated with a phytobezoar in an adolescent.
2002
Esophageal achalasia is an uncommon condition in children. The authors report on a 14-year-old girl who showed a very unusual association of cardiospasm and hypertrophic pyloric stenosis with a gastric phytobezoar.
Muscle hypertrophy, strength development, and serum hormones during strength training in elderly women with fibromyalgia.
2005
To examine the effects of strength training on maximal force, cross-sectional area (CSA), and electromyographic (EMG) activity of muscles and serum hormone concentrations in elderly females with fibromyalgia (FM).Twenty-six patients with FM were randomly assigned to a training (FMT; n = 13; mean age 60 years) or a control (FMC; n = 13; 59 years) group. FMT performed progressive strength training twice a week for 21 weeks. The measurements included maximal isometric and concentric leg extension forces, EMG activity of the vastus lateralis and medialis, CSA of the quadriceps femoris, and serum concentrations of testosterone (T), free testosterone (FT), growth hormone (GH), insulin-like growth…
Morning and smooth 24-h ambulatory blood pressure control is not achieved in general practice: results from the SURGE observational study.
2013
BACKGROUND The aim of this large-scale, practice-based observational study [Survey with HBPM and ABPM Under Real clinical conditions in General practice to Evaluate BP control in the early morning (SURGE)] was to ascertain the degree of morning and 24-h ambulatory blood pressure (ABP) control in hypertensive patients. METHODS Hypertensive patients [with uncontrolled clinic blood pressure (BP) >140/90 mmHg at screening] from nine different countries were included. Ambulatory BP monitoring was performed over 24 h at 15-min intervals during the day and at 20-min intervals during the night. Assessments included morning (0600-1159 h) and daytime ABP control (BP < 135/85 mmHg), and 24-h ABP contr…
