Filter by:The aim of this study was to evaluate the changes in the thickness of abdominal muscles during activation of thoracolumbar fascia through contracting the gluteus maximus and latissimus dorsi muscles. The hypothesis was that the thickness of transversus abdominis and internal oblique would show greater increase when abdominal contraction was performed with simultaneous contraction of gluteus maximus and latissimus dorsi (bridge with arm extension) than that of abdominal contraction alone (abdominal hollowing) or abdominal contraction with simultaneous activation of only gluteus maximus (bridge). Thirty healthy subjects (15 women, 15 men) were enrolled in this cross-sectional study. Thickness of transversus abdominis, internal oblique and external oblique muscles were evaluated using ultrasound at rest and during three exercise positions: abdominal hollowing in neutral spine, bridge, and bridge with isometric arm extension using ultrasound device equipped with 55 mm convex array transducer
The purpose of this study is to investigate the effectiveness of progressive muscle relaxation (PMR) exercise on pain, functional outcomes and muscle strength in patients with TKA. Seventy patients with TKA are going to randomly assigned to intervention group and control group.
Reliability of isokinetic strength measurement of the knee in typically developing children has yet been studied and seems to be good. Because in daily life activities strength of the hip- and ankle-joint muscles are also important, the investigators aim to study the reliability and validity of isokinetic strength measurements of the hip and ankle.
Recent research suggests that performing resistance exercise training with relatively light loads is equally as effective at increasing muscle mass and muscle strength as performing resistance exercise training with relatively heavy loads. Whether or not performing resistance exercise with relatively heavy loads or light loads is equally as effective between the upper- and lower-body within the same individual has never been investigated. Given the substantial individual variance in resistance exercise training-induced changes in muscle mass and strength, this study is designed to quantify the relative influence that extrinsic training variables (e.g., load), as opposed to intrinsic muscle-based predisposition, has on resistance training-induced changes in muscle mass and muscle strength.
In the field of sports training and recovery, the work of muscular strength has become the star theme in terms of its influence on the performance of athletes. In fact, in relation to the training of the inferior members, the scientific evidence indicates that, to increase the other two physical qualities conditioned (speed and resistance), it is necessary to work and to increase the muscular strength. Randomized intervention trial with sample size of 80 subjects divided into 4 groups (n = 20) of muscular work: concentric, eccentric, concentric-eccentric and isometric. Ages between 21-23 years. For all the above, the investigators will study as a main objective analyze what type of muscular work is most effective in order to improve some variables of the performance of explosive muscular strength, and to try to determine if that improvement is due, exclusively to the developed training or to the genetics of the subjects and compare the results obtained in the variables of vertical jump, power of saint, horizontal jump and speed 60 meters, before and after the execution of each one of the muscular works dynamic among themselves, and compared to the muscular work isometric.
Final objective of critical care is no longer only survival. The role of medical and paramedical teams should also be to restore functional capacities, autonomy and quality of life. What has been call "intensive care unit - acquired weakness" (ICU-AW) is associated to acute and long term increased mortality, prolonged ICU and hospital stay, prolonged duration of mechanical ventilation, altered quality of life in survivors and increased health-related costs. In order to target efficient secondary prevention and early rehabilitation, prompt identification of muscle weakness is crucial. Several methods, aiming to assess muscle mass, muscle strength or physical function, are described. Manual muscle testing using the Medical Research Council (MRC) scale is still the most commonly utilized tool to diagnose ICU-AW (MRC <48/60). Dynamometry is an objective alternative and one of the most accurate clinimetric tool to assess muscle strength. Literature is overflowing with insufficiently standardized dynamometry data. Using the investigator's published standardized protocol of quadriceps strength (QS) assessment, this observational study aim to describe physical performances of CC patients and thus to define the weakest ones, by comparing them to surgical and healthy subjects.
A strength training session promotes increased muscle sensitivity to protein synthesis, which lasts for 24 hours after its closure. Recent studies have shown that the subsequent intake to the training session of approximately 20g or 0.24g / kg of high-quality protein in the same meal induces a plateau in this synthesis. Thus, this study aims to compare the muscular strength between vegetarian and omnivorous athletes with adequate protein intake to reach this plateau. It will recruit 64 university sportsmen who have maintained vegetarian or omnivorous diet for at least 6 months, totalizing 32 individuals per group. After signing the Term of Consent, participants will be submitted to anthropometric and body composition assessment (via DEXA), neuromuscular tests [(ie, muscle strength - 1RM, peak torque of knee extensors (JE), muscle thickness of JE and cohort analysis (ANCOVA) will be used in order to compare the results of the study, and to compare the results of the covariance analysis (ANCOVA). the levels of the neuromuscular parameters between the groups, considering the initial values of the force and the initial muscular thickness as covariables, the other parameters will be presented in the form of mean and standard deviation or median, the differences will be considered significant for values of p <0, 05. Expected to find no differences in strength and muscle thickness between vegetarians and omnivores after adequate protein intake.
Background:It has been reported in previous studies that more motor units are fired with electrical stimulation than voluntary muscle contraction, and even high intensity currents provide 10-30% more contractions than voluntary muscle contraction. Objective:This study was planned to compare the effectiveness of high voltage pulsed galvanic (HVPG) stimulation, Russian current and isometric exercise on quadriceps femoris (QF) isometric muscle strength in healthy young women. Methods:Forty-six healthy young women were included in the study (mean age=21.02 ± 1.27). Before and after the training, the dominant side QF isometric muscle strength of participants was assessed with the Isokinetic Dynamometer . The peak torque and average torques of the participants were recorded after the test. The training was planned as HVPG current for the the first group (n = 16), as Russian current for the second group (n = 15) and as isometric strengthening for the third group (n = 15). All treatments were performed under physiotherapist supervision for a total of 15 sessions for 3 days a week for 5 weeks.
Investigator researched that the effect of trunk and lower extremity muscle strength on hamstring flexibility in children with Duchenne Muscular Dystrophy.
Vitamin B12 deficiency can cause severe problems with the blood, nerves, brain and psychological well-being. Ironically, our modern methods for the control of diabetes mellitus can actually contribute to vitamin B12 deficiency. This is because the diabetic medication "metformin", low-cholesterol diets lacking in meats (a natural source of vitamin B12) and the use of powerful anti-gastric medication can all reduce the natural absorption of vitamin B12 from the diet, especially in elderly people with diabetes. There is both a high prevalence of vitamin B12 deficiencies and falls among the elderly with type 2 diabetes mellitus and the investigators hypothesize that B12 deficiency contributes directly and significantly to falls in elderly diabetics through impaired muscle strength, gait and balance. This study therefore proposes to investigate the association between vitamin B12 deficiency and fall risk among diabetic elderly patients (older than 65 years) in the polyclinic setting by assessing muscle strength, balance and walking speed. The predictors of vitamin B12, folate, homocysteine and vitamin D levels will also be explored in this study. If the hypothesis is right, this would be of public health importance & can lead to further studies that can change the way we treat diabetes by reducing falls in our elderly diabetics through the screening for, prevention and treatment of B12 deficiency.
