Clinical Relevance of a Balance Training Program on Liver Transplant Patients. A Randomized Controlled Trial
2019
Background. Although some studies have reported significant improvements in physical function and strength after training programs on liver transplant (LT) recipients, there is a lack of knowledge on how it affects in static and dynamic balance, being an important part of these participants' tasks development. The aim of the study was to determine the effects of a 6-month multicomponent circuit training program on static and dynamic balance in LT participants. Methods. Fifty-four participants were randomized at 6 months after LT into 2 groups: exercise (EXER) group and control (CONTROL) group, with repeat testing at 6 (baseline) and 12 months after LT. The intervention consisted of a multic…
Prognostic evaluation of biofeedback response in patients treated for anorectal malformation
2015
Abstract Purpose Functional bowel outcome in patients with anorectal malformation often is poor. For fecal incontinence resulting from sphincter dysfunction, biofeedback (BFB) training appears to be effective. The aim of study was to investigate the bowel function in incontinent children treated for ARM, using a clinical score, a manometric and pelvic magnetic resonance evaluation, in order to establish predictive parameters of response after BFB. Methods 25 children (median age of 6.5years) with true fecal incontinence were evaluated by clinical score, anorectal manometry and magnetic resonance imaging (MRI). According to these evaluations patients were divided in 4 groups: group 1 (favora…
Effects of progressive resistance exercise in akinetic-rigid Parkinson's disease patients: a randomized controlled trial.
2017
Progressive resistance exercise (PRE) can have a positive effect in individuals with Parkinson’s disease (PD). However, the effect of PRE may vary with the clinical subtype of PD. To date, no study has assessed the effects of PRE in the different subtypes of PD. AIM: The aim of the present study was to assess the effects of PRE in PD patients with akinesia and rigidity (AR-subtype). DESIGN: A randomized controlled trial was conducted. SETTING: Outpatients clinics of the Bierzo Parkinson Association (Ponferrada, Spain) and the Asturias Parkinson Association (Oviedo, Spain). POPULATION: Twenty-eight patients with AR-subtype PD were randomized into an Experimental Group (EG, N.=13) and Control…
Biomechanical Comparison Between Sprint Start, Sled Pulling, and Selected Squat-Type Exercises
2013
The purpose of this study was to compare kinetics, kinematics, and muscle activity among sprint start, sled pulling, and selected squat-type exercises (countermovement jumps [CMJs] and 1/2-squats with various loads) and also to examine how these exercises correlate with the performance time of the block start (10 m). Nine male athletes (4 sprinters, 3 decathlonists, 1 long jumper, and 1 triple jumper: age = 24.9 ± 3.9 years; 100-m record = 11.35 ± 0.29 seconds; track and field training years = 11.8 ± 3.1 years) volunteered as subjects. The comparisons were made with regard to the block phase (the phase of force production toward starting blocks) of the block start. In nearly all exercises, …
Training Effects of Alternated and Pulsed Currents on the Quadriceps Muscles of Athletes
2018
AbstractThe aim of the study was to evaluate the effects of 6 weeks training with different neuromuscular electrical stimulation (NMES) currents (medium alternated and low-frequency pulsed current) on muscle architecture and neuromuscular performance of competitive athletes. A double-blind controlled and randomized experimental study was carried out with 33 athletes (22.2±2.6 yrs, 74.7±9.8 kg, 176.8±6.0 cm), divided into 3 groups: mid-frequency current (MF, n=12), pulsed current (PC, n=11) and the control group (CG, n=10). Quadriceps maximal voluntary peak torque (PT) and corresponding vastus lateralis electromyographic activity, evoked torque (PT-NMES), vastus lateralis muscle thickness, f…

Collagen of slow twitch and fast twitch muscle fibres in different types of rat skeletal muscle
1984
The appearance of collagen around individual fast twitch (FT) and slow twitch (ST) muscle fibres was investigated in skeletal muscles with different contractile properties using endurance trained and untrained rats as experimental animals. The collagenous connective tissue was analyzed by measuring hydroxyproline biochemically and by staining collagenous material histochemically in M. soleus (MS), M. rectus femoris (MRF), and M. gastrocnemius (MG). The concentration of hydroxyproline in the ST fibres dissected from MS (2.72 +/- 0.35 micrograms X mg-1 d.w.) was significantly higher than that of the FT fibres dissected from MRF (1.52 +/- 0.33 micrograms X mg-1 d.w.). Similarly, the concentrat…
Influence of visual cues on gait in Parkinson's disease during treadmill walking at multiple velocities.
2011
Abstract Objective To evaluate the interaction of different treadmill-induced gait velocities and visual cues on the gait performance in Parkinson's disease (PD). Background External cuing has been reported to facilitate hypokinetic gait patterns in PD. Methods 19 PD-patients and 17 controls volunteered for the study. Gait analyses were conducted using dynamic pressure sensors integrated in a treadmill at a given velocity of 1, 2, 3 or 4 km/h. For each velocity, measurements were performed under three conditions. The first condition was without visual cuing, the remaining two consisted of visual cuing e.g. white stripes put on the treadmill belt 25 or 50 cm apart. Results Visual cuing lower…
The involvement of MMP-2 and MMP-9 in heart exercise-related angiogenesis
2013
Background Little is known about the involvement of matrix metalloproteinases (MMPs) in cardiac vascular remodelling induced by exercise. Our aim was to evaluate and localize MMP-2 and MMP-9’s activities in relation to capillary proliferation in mouse hearts trained for 15, 30 and 45 days. Methods Sixty-three mice were randomly assigned to 7 groups: four control sedentary groups (C0, C15, C30 and C45) and three groups trained by an endurance protocol (T15, T30 and T45). MMP-2 and MMP-9 were examined with zymography and immunostaining analyses. Capillary proliferation was evaluated counting the number of CD31-positive cells. Results Different activity patterns of the latent form of both MMPs…
Home-exercise Childhood Obesity Intervention: A Randomized Clinical Trial Comparing Print Versus Web-based (Move It) Platforms.
2018
Abstract Purpose To compare the impact of adhering to a Mediterranean diet plus mixed physical exercise program (Move-It) implemented by means of printed instructions or via a web-platform (with or without e-mail support) on body composition, physical fitness, and blood pressure. Design and Methods Randomized clinical trial. Fifty-two overweight or obese Spanish children and adolescents were randomly assigned to the print-based (n = 18), Move-It (n = 18), or Move-It plus support (n = 16) intervention groups. Two-way mixed ANOVA tests were used to compare any changes between the groups in terms of percentage body fat, physical fitness (VO2peak), handgrip strength, and systolic and diastolic …
