The purpose of this study was to determine the effects of training load (25% vs. 75% of one repetition maximum (1RM)) and fatigue (failure vs. non‐failure) during four weeks of unilateral knee extension resistance training (RT) on maximal voluntary force in the trained and the untrained knee extensors. Healthy young adults (n=42) were randomly assi...
The role of transcranial direct current stimulation (tDCS) as an ergogenic aid is receiving attention from scientists to optimize sport performance. Most studies have examined the effects of tDCS on endurance performance during continuous tasks, while the effect of tDCS on high-intensity intermittent tasks has been less investigated. Therefore, thi...
Repetitive, monotonic, and effortful voluntary muscle contractions performed for just a few
weeks, i.e., resistance training, can substantially increase maximal voluntary force in the
practiced task and can also increase gross motor performance. The increase in motor
performance is often accompanied by neuroplastic adaptations in the central nervou...
This study aimed to compare acute and delayed markers of mechanical, neuromuscular, and biochemical fatigue between resistance training sessions leading to or not to failure. Twelve resistance-trained men completed 2 sessions that consisted of 6 sets of the full-squat exercise performed against the 10 repetitions maximum load. In a randomized order...
Transcranial direct current stimulation (tDCS) has been proven to induce positive effects on athletic performance.

Cortical excitability increases during the performance of more difficult postural tasks. However, it is possible that changes in postural threat associated with more difficult tasks may in itself lead to alterations in the neural strategies underlying postural control. Therefore, the purpose of this study was to examine whether changes in postural...
Background: Eccentric actions allows to apply 20-50% greater strength than concentric. This effort may induce a more rapid protein synthetic response and greater increase in anabolic signalling (Franchi et al., 2014). Moreover, ECC actions produces disruption to contractile, structural, and supportive elements (Enoka, 1996), due to specific force d...
Research has indicated that at the onset of a finger movement, unwanted contractions of adjacent muscles are prevented by inhibiting the cortical areas representing these muscles. This so-called surround inhibition (SI) seems relevant for the performance of selective finger movements but may not be necessary for tasks involving functional coupling...
Introduction:
Unilateral resistance training has been shown to improve muscle strength in both the trained and the untrained limb. One of the most widely accepted theories is that this improved performance is due to nervous system adaptations, specifically in the primary motor cortex. According to this hypothesis, increased corticospinal excitabil...
Revisión sistemática sobre los efectos del entrenamiento unilateral sobre el balance excitatorio-inhibitorio del tracto corticoespinal.
Introduction: Unilateral resistance training can improve muscle strength of the trained and also of the untrained limb. Presumably such
improvements are neural in nature and they are related to increases in activation of brain areas ipsilateral to the practicing limb. The purpose of this review is to determine if cross education of muscle strength...

Gait disturbances are one of the principal and most incapacitating symptoms of Parkinson’s disease (PD). In addition, walking economy is impaired in PD patients and could contribute to excess fatigue in this population. An important number of studies have shown that treadmill training can improve kinematic parameters in PD patients. However, the ef...
AimIt is accepted that leg stiffness (Kleg) increases when surface stiffness decreases, and vice versa. However, little is known how the central nervous system fulfills this task.

INTRODUCTION Weighted sled towing is a popular resisted sprint training methods. Several researches have shown acute effects on sprint kinematics during a sled towing exercise, in athletes such as sprinters and rugby players (Cronin et al., 2008; Lockie et al., 2003, Alcaraz et al., 2008). However, to our knowledge no one has been carried out in so...
INTRODUCTION Sled towing training has become a popular method for speed training. However, its effects on running kinetics remain unclear. Few studies have been performed on how resisted training can affect vertical and leg stiffness (Brughelli et al., 2008; Alcaraz et al., 2012). The purpose of this study was to investigate how stiffness is affect...
BACKGROUND: Startle stimuli lead to shorter reaction times in control subjects and Parkinson's disease (PD) patients. However, non-startle stimuli also enhance movement initiation in PD. We wanted to examine whether a startle-triggered movement would retain similar kinematic and EMG-related characteristics compared to one induced by a non-startle e...
The force enhancement of muscle twitch contraction after a maximal voluntary contraction (MVC) has been defined as post-activation potentiation. However, the effects of post-activation potentiation on ballistic movements have not been studied extensively, or the underlying neurophysiologycal mechanism. In the current study, we examined post-activat...
Central and peripheral fatigue have been explored during and after running or cycling exercises.

Introduction.
Parkinson’s disease (PD) is a progressive degenerative disorder of the central nervous system (CNS). Its clinical manifestations include 4 cardinal signs: tremor, rigidity, bradykinesia and postural instability (Rossi et al., 2009). Postural instability represents a highly disabling and poorly treatable symptom that interferes with t...
After repeated jumps over an elastic surface (e.g. a trampoline), subjects usually report a strange sensation when they jump again overground (e.g. they feel unable to jump because their body feels heavy). However, the motor and sensory effects of exposure to an elastic surface are unknown. In the present study, we examined the motor and perceptual...
Patients with Parkinson's disease (PD) improve gait after treadmill training and while they are walking over the treadmill. However, the mechanisms of these improvements have not been addressed. We designed a treadmill simulator without a belt that could move on a walkway in a constant speed, in order to explore the mechanism underlying treadmill w...
Within the motor system, cortical areas such as the primary motor cortex (M1) and the ventral premotor cortex (PMv), are thought to be activated during the observation of actions performed by others. However, it is not known how the connections between these areas become active during action observation or whether these connections are modulated by...
Players (eg, basketball, soccer, and football) often use a static bicycle during a game to maintain warming. However, the effectiveness of this procedure has not been addressed in the literature. Thus, it remains unknown whether low-intensity cycling movement can affect explosive movement performance. In this study, 10 male subjects performed count...
Several studies suggest that transcutaneous electrical stimulation (TENS) can have a variety of effects on the central nervous system (CNS). In this study, we tried to replicate the physiological effects of TENS and to explore its effects on intracortical circuits.
We used transcranial magnetic stimulation (TMS) and spinal reflex testing to examine...

To investigate early and late neural responses induced by different HIIT protocols. We are testing corticospinal responsiveness and how it counteracts with changes in brain and muscle oxygenation induced by different HIIT protocols. We also test spinal and supraspinal responses induced by short-term HIIT (12 sessions).
To investigate whether different loading conditions affect reflex responses during hopping
We aim to verify: 1) the influence of a strength training program on PAP responses, running economy and pacing; 2) the effect of circadian rhythms on PAP responses; 3) the relationship between jump capacity, MVC, and twitch responses after an incremental test; 4) the influence of intensity and volume of running on PAP responses and MLC phosphorylation.
