Adolescents' postural control learning according to the frequency of knowledge of process

2019

Feedback is one of the most influential factors for motor skills learning. Physical Education teachers commonly use verbal cues to provide knowledge of process (KP) when teaching motor skills, but the ideal presentation frequency for KP in adolescents is unclear. The aim of this study was to compare the effectiveness of the frequency of KP (i.e., 100%, 67%, 0%) on dynamic balance. Thirty adolescents, age 14–15 years, participated in the study. Performance on a stabilometer platform was used to assess dynamic balance. Participants received feedback after each trial (100%), in two out of three trials (67%), or no feedback during 12 30-s trials of practice. Adolescents who received feedback (6…

Building dynamic balanced scorecards to enhance strategy design and planning in public utilities. Key-findings from a project in a city water company

2006

Increasing complexity and uncertainty of both business internal and external variables determines a growing need for prompt and accurate information. On this concern, in the last decade, there has been an increasing effort to provide public utilities with tools aimed to support decision makers in planning and control, by taking into account not only operational but also strategic issues. Among them, for 1instance, customer satisfaction, internal business process efficiency, business image, and bargaining power against other counterparts (e.g. the municipal administration). Often, however, such an effort has been oriented to generate a large volume of data, only focused on financial indicato…

Age dependency of neuromuscular function and dynamic balance control

2010

Abstract The purpose of the present study was to examine whether static and dynamic balance control are related to neuromuscular function and ageing. For this purpose, we constructed a new dynamic balance measurement system that simulates natural falling. Ten young (age 21–31 years) and 20 elderly (age 60–70 years) men participated in the experiment. Maximal isometric torque (MVC) and activation level were measured from the quadriceps and plantar flexor muscles. The H-reflex, V-wave, and maximal M-wave were measured from the soleus muscle. In dynamic balance control, anterior-posterior centre-of-pressure swaying was 74±8.1 mm in the young men and 91.5±19.4 mm in the elderly men (P<0.05), wh…

Modulation of H-reflex and V-wave responses during dynamic balance perturbations

2023

AbstractMotoneuron excitability is possible to measure using H-reflex and V-wave responses. However, it is not known how the motor control is organized, how the H-reflex and V-wave responses modulate and how repeatable these are during dynamic balance perturbations. To assess the repeatability, 16 participants (8 men, 8 women) went through two, identical measurement sessions with ~ 48 h intervals, where maximal isometric plantar flexion (IMVC) and dynamic balance perturbations in horizontal, anterior–posterior direction were performed. Soleus muscle (SOL) neural modulation during balance perturbations were measured at 40, 70, 100 and 130 ms after ankle movement by using both H-reflex and V-…

Effect of a HIIT protocol on the lower limb muscle power, ankle dorsiflexion and dynamic balance in a sedentary type 1 diabetes mellitus population: …

2020

Background Type 1 diabetes mellitus (T1DM) is commonly associated with premature loss of muscle function, ankle dorsiflexion and dynamic balance. Those impairments, usually, lead to physical functionality deterioration. High-intensity interval training is an efficient and safety methodology since it prevents hypoglycemia and not requires much time, which are the main barriers for this population to practice exercise and increase physical conditioning. We hypothesized that a 6-week HIIT program performed on a cycle ergometer would increase lower limb muscle power, ankle dorsiflexion range of motion and dynamic balance without hypoglycemic situations. Methods A total of 19 diagnosed T1DM sub…

A lower-limb training program to improve balance in healthy elderly women using the T-Bow® Device

2009

Ageing impairs balance, which increases the risk of falls. Fall-related injuries are a serious health problem associated with dependency and disability in the elderly and results in high costs to public health systems. This study aims to determine the effects of a training program to develop balance using a new device called the T-Bow (R). A total of 28 women > 65 years were randomly assigned to an experimental group (EG) (n = 18; 69.50 [0.99] years), or a control group (CG) (n = 10; 70.70 [2.18] years). A program for lower limbs was applied for 8 weeks using 5 exercises on the T-Bow (R): squat, lateral and frontal swings, lunges, and plantarflexions. The intensity of the exercises was cont…

Efficacy of 12 weeks of proprioceptive training in patients with multiple sclerosis

2019

This pilot study aims to investigate if specific training protocol can improve the quality of life in people with multiple sclerosis through the improvement of some impaired ability like the balance. We enrolled in our project 20 subjects (age: 34,88 ± 4,45; height: 168,25 ± 8,66 cm; weight: 72,31 ± 17,28 kg) but only 5 completed the study. A proprioceptive training was administered for 12 weeks, 2 times a week, an hour for each session. At the beginning (T0) and at the end of the study (T1), static and dynamic balance parameters were tested. Statistical analyzes were performed using IBM SPSS Statistics 22.Changes in balance and strength between T0, T1 were evaluated using t Student test fo…

Effects of Strength Training on Muscle Strength Characteristics, Functional Capabilities, and Balance in Middle-Aged and Older Women

2006

Progressive strength training can lead to substantial increases in maximal strength and mass of trained muscles, even in older women and men, but little information is available about the effects of strength training on functional capabilities and balance. Thus, the effects of 21 weeks of heavy resistance training--including lower loads performed with high movement velocities--twice a week on isometric maximal force (ISOmax) and force-time curve (force produced in 500 milliseconds, F0-500) and dynamic 1 repetition maximum (1RM) strength of the leg extensors, 10-m walking time (10WALK) and dynamic balance test (DYN.D) were investigated in 26 middle-aged (MI; 52.8 +/- 2.4 years) and 22 older …

Trial on the Possibility to Assess the Static and Dynamic Balance in the Elderly with Diseases on the Level of the Supporting Joints

2019

The study aims to identify human walking disorders, proposing a model to solve these disorders, regardless of what caused them. Material and method Clinical and somatometric tests, pedometric investigations and sensors were used. An outpatient trial was conducted for a period of 6 weeks with a frequency of application of the recovery program of 3 times / week. For this study, there were 21 patients over the age of 65 years, which were divided into two groups: the witness group in which 11 patients had upper limb and / or spine disorders, and the control group with 10 patients with degenerative diseases in the knees and ankles. The tests were applied to both groups following the demographic …
