The most common and severe form of muscular dystrophy is Duchenne (DMD), a disorder caused by the absence dystrophin, structural protein found on cytoplasmic surface sarcolemma striated muscle fibres. Considerable attention has been dedicated to studying myofibre damage plasticity, but there little information determine if from contraction-induced injury occurs at or near nerve terminal axon. We used α-bungarotoxin compare neuromuscular junction (NMJ) morphology in healthy (wild-type, WT)...
Impaired balance, loss of mobility and falls are major problems associated with changes in muscle older adults. However, the extent to which composition related performance measures for different lower limb muscles individuals is unclear. This study evaluated attenuation, intramuscular adipose tissue (IMAT) infiltration fallers non-fallers. For this cross-sectional study, fifty-eight community dwelling (>65 years) were classified into (n = 15) or non-fallers 43). Computed tomography (CT) was...
Background: Intramuscular adipose tissue (IMAT) of the lower extremity is a strong negative predictor mobility function. Variability in temporal gait factors another important The purpose this study was to examine relationships between IMAT hip and thigh muscles, balance, variability older adults. Methods: Forty-eight healthy community dwelling adults (74 +/- 1 year) underwent CT scan quantify gluteus maximus (Gmax), medius/minimus (Gmed/min), hamstrings, vastus lateralis, adductor muscles....
Our cross-sectional study aimed to investigate joint specificity of concentric muscle torque enhancement after a maximum eccentric contraction for the knee versus ankle joints across two different movement velocities (120°/s and 180°/s). After familiarization session, 22 healthy young adults randomly performed (CONC) preloaded (EccCONC) strength tests extensors plantar flexors non-dominant leg on an isokinetic testing device. We calculated ratio between EccCONC CONC (EccCONC/CONC) all...
Abstract Until recently, neural assessments of gross motor coordination could not reliably handle active tasks, particularly in realistic environments, and offered a narrow understanding motor-cognition. By applying comprehensive neuroergonomic approach using optical mobile neuroimaging, we probed the correlates functioning young people with Developmental Coordination Disorder (DCD), motor-learning deficit affecting 5–6% children lifelong complications. Neural recordings fNIRS were collected...

J Strength Cond Res 25(4): 896-902, 2011-The purpose this study was to assess the threshold where simulated adipose tissue weight gain significantly affects performance in common tasks determine whether differences exist between men women. Forty-six subjects (men = 21; women 25) were tested for vertical jump, 20- 40-yd dash, 20-yd shuttle tests under 6 different...
Developmental coordination disorder (DCD) is characterized by motor learning deficits that are poorly understood within whole-body activities context. Here we present results of one the largest non-randomized interventional trials combining brain imaging and motion capture techniques to examine skill acquisition its underpinning mechanisms in adolescents with without DCD. A total 86 low fitness levels (including 48 DCD) were trained on a novel stepping task for duration 7 weeks. Motor...
BackgroundDevelopmental coordination disorder affects approximately 6% of children, interfering with participation in physical activity and can persist through adulthood. However, no studies have investigated the neuromotor mechanisms learning a novel task rhythmic cueing.MethodsMovement Assessment Battery for Children-2nd edition was used to identify 48 children probable developmental (13.9 ± 0.05 yrs., 27% male) 37 typically developed 0.10 54% male). While instrumented an inertial...
Diabetes mellitus (DM) is a clinical condition that affects gait performance and control in millions of individuals worldwide. Contrary to basic spatiotemporal parameters, gait-based spectral analysis may provide useful insights into neuromotor control. Hence, this study was set investigate the content at preferred speed patients with DM. Total 1117 [658 DM 649 healthy adults (HA)] performed 10 m walk while wearing an inertial measurement unit over fourth lumbar vertebra. Mann-Whitney-U test...
PURPOSE: The purpose of this study was to assess the threshold where simulated adipose tissue weight gain significantly affects performance in common anaerobic tasks, and determine whether differences exist between men women. METHODS: 46 subjects (male = 21; female 25) were tested for vertical jump, 20 40 yard dash, shuttle tests under six different loading conditions (0, 2, 4, 6, 8 10 % added body weight). Results compared each subject's baseline values (0% condition). RESULTS: demonstrate...
Abstract BACKGROUND AND AIMS Chronic kidney disease (CKD) is a highly predominant worldwide disease, representing an enormous economic burden with profound social implications. In addition to frequent infections and mineral bone disorders, CKD patients also experience exacerbated mobility deficits severe skeletal muscle wasting, which further contributes the development of co-morbidities increased mortality. suffering from end-stage renal often undergo dialysis treatment, such as peritoneal...
Joint specific stretch-shortening cycle (SSC) potentiation of lower extremity joints at propulsion onset during jump test performance (JTP) can temporally affect SSC potentiation. However, joint-specific JTP is unknown.Twenty-two healthy young adults, 12 men and 10 women, performed: vertical jumps (1) with a preliminary countermovement (CMJ), 2) from squat position held isometrically for 2-3 seconds the same knee angle CMJ (SJ), (3) after landing 15 cm high platform (DJ). Kinetics kinematics...
Abstract Until recently, neural assessments of gross motor coordination could not reliably handle active tasks, particularly in realistic environments, and offered a narrow understanding motor-cognition. By applying comprehensive neuroergonomic approach using optical mobile neuroimaging, we demonstrated the broader capability for ecologically relevant evaluations “difficult-to-diagnose” Developmental Coordination Disorder (DCD), motor-learning deficit affecting 5-6% children with lifelong...
