The study investigated changes in motor output and unit behavior following 6 wk of either strength or endurance training programs commonly used conditioning rehabilitation. Twenty-seven sedentary healthy men (age, 26.1 ± 3.9 yr; mean SD) were randomly assigned to (ST; n = 9), (ET; 10), a control group (CT; 8). Maximum voluntary contraction (MVC), time task failure (isometric at 30% MVC), rate force development (RFD) the quadriceps measured before ( week 0), during 3), after program wk. In...
This study examined the effects of 3 wk either endurance or strength training on plasticity neural mechanisms involved in soleus H reflex and V wave. Twenty-five sedentary healthy subjects were randomized into an group (n = 13) 12). Evoked V-wave, H-reflex, M-wave recruitment curves, maximal voluntary contraction (MVC), time-to-task-failure (isometric at 40% MVC) plantar flexors recorded before after training. Following training, MVC increased by 14.4 ± 5.2% (P < 0.001), whereas was...
Purpose The H reflex recruitment curve represents the gold standard for quantifying changes in spinal circuitries. However, there is no agreement on how many stimulations should be applied each parameter. Thus, we explored impact of varying number (3, 6, 9, 12 and 15 stimuli per intensity) between-day reliability soleus reflex.
Background: The aim of this trial is to compare the effects two types exercises, Global Postural Re-education versus specific therapeutic exercises on pain perception, threshold pressure, psychosocial factors associated with pain, and craniocervical posture in women chronic nonspecific neck pain. Methods: This study a randomized, parallel-group, single-blind clinical trial. Fifty-two (two excluded) were recruited randomly assigned (n = 25) exercises. Interventions carried out for 4 weeks,...
This study investigates the effects of eccentric exercise and delayed onset muscle soreness (DOMS) quadriceps on agonist-antagonist activity during a range motor tasks. Ten healthy volunteers (age, mean ± SD, 24.9 3.2 years) performed maximum voluntary contractions (MVC) explosive isometric knee extensors followed by at 2.5, 5, 10, 15, 20, 30% MVC baseline, immediately after 24 h quadriceps. During each task, force surface EMG vasti hamstrings muscles were recorded concurrently. Rate...
BACKGROUND: Neck pain is associated with decreased health-related quality of life, work productivity, and increased visits to health care providers.AIM: The aim this study was assess the effectiveness "Global Postural Re-education" (GPR) versus a neck specific exercise (SE) program on pain, disability, cervical range movement, postural stability, activity superficial flexor muscles.DESIGN: A parallel-group single-blinded clinical trial.SETTING: Community interventions.POPULATION: Fifty women...

Older people in low-population density regions tend to have fewer resources engage regular physical activity (PA) compared their counterparts urban areas. Moreover, PA assumes different dimensions, and the amount of related each dimension may differ between women men, predisposing them practices. Therefore, this cross-sectional study aims describe prevalence barriers PA, gender differences, associations with dimensions. A total 259 older adults (153 106 men; age, 75.17 ± 8.05 years old)...
Eccentric contractions induce muscle fiber damage that is associated with a decreased capacity to generate voluntary force and increased membrane permeability. Changes in permeability results cell depolarization expected have an effect on the action potential propagation velocity of fibers.The aim study was investigate individual motor units before 24 48 h after eccentric exercise.Multichannel surface fine-wire intramuscular EMG signals were concurrently recorded from two locations right...
Chronic nonspecific neck pain is the most frequent form of pain. It more prevalent in women, and a costly public health issue. commonly associated with biomechanical, functional, proprioceptive, postural impairments. The aim this trial to compare effects global exercises versus specific therapeutic on pain, disability, mobility, pressure threshold, kinesiophobia, catastrophizing, control, neuromuscular efficiency women chronic Methods analysis: This study randomized, parallel-group single...
Health-related quality of life (HRQoL) is influenced by several factors, such as living place, physical activity (PA), and functional fitness levels. Evidence shows that PA levels are strongly associated with positive HRQoL, especially in the older population. However, impact place has not been investigated an influencing variable this context. Therefore, study aimed to investigate relationship between PA, adults rural urban areas Portugal. A cross-sectional was performed community-dwelling...
Abstract Biomarkers of ageing serve as important outcome measures in longevity-promoting interventions. However, there is limited consensus on which specific biomarkers are most appropriate for human intervention studies. This work aimed to address this need by establishing an expert use studies via the Delphi method. A three-round study was conducted using online platform. In Round 1, panel members provided suggestions candidate ageing. Rounds 2 and 3, they voted 500 initial statements...
Abstract Purpose Most studies examining the predictive value of load–velocity relationship in determining one-repetition maximum (1RM) back squat implemented its direct determination to enable testing movement velocity within a predetermined set relative loads (e.g., 50, 60, 70, 80, and 90% 1RM). We determined whether different approach profiling affects accuracy estimating 1RM. Methods Predictions based on practical 2-point (no pre-determination 1RM) were compared those obtained with...
Purpose The objectives were to analyse differences of static and dynamic balance between sexes test the correlations measures. Methods study involved 77 physically active adults, university students (age: 19.1 ± 1.1 years; height: 170.2 9.2 cm; body mass: 64.1 10.7 kg). Static was assessed with a force platform under Romberg conditions: foam surface, eyes open (EOFS); closed (ECFS); challenging visual-vestibular system (CVVS). Y Balance Test (YBT) evaluated in anterior, posteromedial,...
Human cognitive-motor performance largely depends on how brain resources are allocated during simultaneous tasks. Nonetheless, little is known regarding the age-related changes in electrocortical activity when dual-task walking presents higher complexity levels. Thus, aim of this study was to investigate whether there distinct and activation between young older adults performing simple complex upper limb response time Physically active (23 ± 3 years, n = 21) (69 5 19) were asked respond as...
Children aged 10-11 years pass through a dynamic developmental period marked by rapid changes in body size, shape, and composition, all of which are sexually dimorphic. The purpose this study was to analyze the effects gender on school-based intervention prepubertal growth spurt. One hundred twenty-five healthy children (58 boys, 67 girls), fifth sixth grade students from an urban public elementary school Portugal (10.8 ± 0.4 years), were randomly assigned into two experimental groups:...
We studied the long-term effects of a multicomponent exercise training protocol (recreational team handball training, RTH) on global health status in inactive postmenopausal women.

New Findings What is the central question of this study? How do H‐reflex and V‐wave excitability compare between men women engaging in similar levels physical activity? main finding its importance? lower than because their greater level antagonist co‐activation during sustained plantar flexion isometric exercise. In addition, supraspinal drive independently differences muscle co‐activation. Abstract We compared activity. also explored whether sexes might partially explain sexual dimorphism...
Abstract Despite being apparently safe for most individuals, the impact of low intensity (LI) blood-flow restricted (BFR) exercise on nerve function and integrity is still obscure. We explored whether BFR (with without exercise) alters properties conduction measured at level limb. Thirteen healthy, young men (22.0 ± 1.7 years) were included in this study. Arterial occlusion pressure was taken rest. Soleus M- H-recruitment curves constructed all participants. H-wave latencies amplitudes...
