1. Neural adaptations in isometric contractions with EMG and force biofeedback
"Adaptações neurais em contrações isométricas com biofeedback EMG e de força." Este estudo avaliou as adaptações neurais do quadríceps durante contrações isométricas usando os sinais de força e eletromiografia (EMG) como biofeedback. Quarenta e dois sujeitos foram distribuídos em três grupos: EMG, testado com biofeedback da EMG; Força, testad

2. Neural and morphological adaptations of vastus lateralis and vastus medialis muscles to isokinetic eccentric training
"Adaptações neurais e morfológicas dos músculos vasto lateral e vasto medial para treinamento isocinético excêntrico." Vasto lateral (VL) e vasto medial (VM) são comumente visados em programas de condicionamento/reabilitação devido ao seu papel na estabilização patelar durante a extensão do joelho. Este estudo avaliou as adaptações neurais e mu

3. Adaptações neuromusculares e morfológicas de treinamentos de força realizados com amplitudes total e parcial de movimento
O objetivo deste estudo foi comparar as adaptações neuromusculares e morfológicas de treinamentos de força realizados com amplitudes parcial e total de movimento nos músculos flexores de cotovelo e extensores de joelho. Participaram do estudo 41 voluntários do sexo masculino destreinados em força (23,78 ± 3,27 anos), divididos em três grupos: PS-TI

4. Influência dos treinamentos de força e potência nas adaptações neurais, morfológicas e na funcionalidade em idosos / Comparison between strength and power training on neural, morphological and functional adaptations in the elderly
Apesar das perdas provocadas pela sarcopenia, o sistema neuromuscular do idoso ainda mantém parte da sua plasticidade. No entanto, as adaptações promovidas pelos treinamentos de força (TF) e de potência (TP) não foram totalmente elucidadas, assim como se existem diferenças entre essas adaptações nessa população. Para responder tais questões, 43 i

5. Neural changes in the spinal cord rights for different types of physical training / Adaptações neurais na medula espinhal de humanos para diferentes tipos de treinamento físico
Introduction: Neural adaptations with physical training have been widely studied. The spinal cord is a possible locus of adaptation. However, longitudinal studies that evaluate directly the spinal cord pathways have not been found in the literature. Therefore, all reports from the literature justify changes found in measured responses to exercise by hypothes

6. Efeitos do treinamento concorrente na força e ativação muscular, capacidade aeróbica e em hormônios e esteróides em homens idosos
O treinamento concorrente de força e endurance têm sido amplamente investigado em diversas populações. Contudo, poucos estudos compararam seus efeitos com o treino de força e endurance isolados em indivíduos idosos. Sendo assim, o objetivo desse estudo foi investigar os efeitos do treinamento concorrente na força e ativação muscular, capacidade de e

7. Sustained Morphine Treatment Augments Capsaicin-Evoked Calcitonin Gene-Related Peptide Release from Primary Sensory Neurons in a Protein Kinase A- and Raf-1-Dependent Manner
Studies have shown that long-term (5α,6α)-7,8-didehydro-4,5-epoxy-17-methylmorphinan-3,6-diol (morphine) treatment increases the sensitivity to painful heat stimuli (thermal hyperalgesia). The cellular adaptations contributing to sustained morphine-mediated pain sensitization are not fully understood. It was shown previously (J Neurosci 22:6747–6755

8. The adaptive nature of the human neurocognitive architecture: An alternative model
The model of the human neurocognitive architecture proposed by evolutionary psychologists is based on the presumption that the demands of hunter-gatherer life generated a vast array of cognitive adaptations. Here we present an alternative model. We argue that the problems inherent in the biological markets of ancestral hominids and their mammalian predecesso

9. Neural and biomechanical specializations of human thumb muscles revealed by matching weights and grasping objects.
1. Human manual dexterity has been linked by some to biomechanical adaptations of the hand and by others to neural adaptations. To investigate neural adaptations, the present study using the performance of four muscles acting on the index and thumb, quantified weight matching and electromyography. 2. The accuracy (i.e. reproducibility) of weight matching was

10. Chronic morphine induces visible changes in the morphology of mesolimbic dopamine neurons.
The mesolimbic dopamine system, which arises in the ventral tegmental area (VTA), is an important neural substrate for opiate reinforcement and addiction. Chronic exposure to opiates is known to produce biochemical adaptations in this brain region. We now show that these adaptations are associated with structural changes in VTA dopamine neurons. Individual V

11. Generalization of Visuomotor Learning Between Bilateral and Unilateral Conditions
A long history of behavioral and physiological research has suggested that bilateral coordination invokes unique neural processes that are not involved in unilateral movements. This hypothesis predicts that motor learning should show limited transfer between unilateral and bilateral conditions, which is consistent with a recent finding that indicated partial

12. Robust passive dynamics of the musculoskeletal system compensate for unexpected surface changes during human hopping
When human hoppers are surprised by a change in surface stiffness, they adapt almost instantly by changing leg stiffness, implying that neural feedback is not necessary. The goal of this simulation study was first to investigate whether leg stiffness can change without neural control adjustment when landing on an unexpected hard or unexpected compliant (soft
