Differences in postural control between healthy and subjects with chronic ankle...
Esteves, José; Dinis, Ricardo; Fernandes, Orlando; Castro, Maria António; Oliveira, Raúl; Pezarat-Correia, PedroIntroduction: Chronic ankle instability (CAI) is characterized by the occurrence of repetitive inversion mechanisms of the ankle, resulting in numerous ankle sprains. CAI occurs in approximately 70% of patients with a history of a lateral ankle sprain. Many causes of functional ankle instability have been postulated and include deficits in proprioception, impaired neuromuscular-firing patterns, disturbed balanc...
Comparison of shoulder and trunk muscle activation between different pullover e...
Pezarat-Correia, Pedro; Medeiros, Pedro; Fernandes, Orlando; Vaz, João; Silva, Luís; Moraes, AntónioObjective: To quantify and compare the electromyographic activity of 10 muscles in three pullover exercises. Methods: 15 healthy men, with at least two years of experience in resistance training, executed in random order six repetitions with 60% of 1 Maximum Repetition for three different pullover exercises: lying on a step with a barbell, grip 100% biacromial (E1); lying on a step with a barbell, grip 150% (E2...
Muscle activity variability patterns and stride to stride fluctuations of older...
Jordão, Sofia; Stergiou, Nick; Brandão, Rita; Pezarat-Correia, Pedro; Oliveira, Raúl; Cortes, Nelson; Vaz, João R.It has been found that fractal-like patterns are present in the temporal structure of the variability of healthy biological rhythms, while pathology and disease lead to their deterioration. Interestingly, it has recently been suggested that these patterns in biological rhythms are related with each other, reflecting overall health or lack of it, due to their interaction. However, the underlying neurophysiologic...
Torque regulation is influenced by the nature of the isometric contraction
Bauer, Philipp; Gomes, João Sá; Oliveira, João; Santos, Paulo; Pezarat-Correia, Pedro; Vaz, João R.The present study aimed to investigate the effects of a continuous visual feedback and the isometric contraction nature on the complexity and variability of force. Thirteen healthy and young male adults performed three MVCs followed by three submaximal isometric force tasks at a target force of 40% of their MVC for 30 s, as follows: (i) push isometric task with visual feedback (Pvisual); (ii) hold isometric tas...
Effects of time-restricted feeding on supramaximal exercise performance and bod...
Correia, Joana Margarida; Santos, Inês; Pezarat-Correia, Pedro; Minderico, Cláudia; Schoenfeld, Brad J.; Vilhena De Mendonca, GoncaloUsing a crossover design, we explored the effects of both short- and long-term time-restricted feeding (TRF) vs. regular diet on Wingate (WnT) performance and body composition in well-trained young men. Twelve healthy male physical education students were included (age: 22.4 ± 2.8 years, height: 174.0 ± 7.1 cm, body mass: 73.6 ± 9.5 kg, body mass index: 24.2 ± 2.0 kg/m2). The order of dieting was randomized and...
Effects of Ramadan and non-Ramadan intermittent fasting on body composition: a ...
Correia, Joana Margarida; Santos, Inês; Pezarat-Correia, Pedro; Silva, Analiza M; Vilhena De Mendonca, GoncaloIntermittent fasting (IF) has gained popularity for body-composition improvement purposes. The aim of this systematic review and meta-analysis was to summarize the effects of Ramadan vs. non-Ramadan IF on parameters of body composition. We conducted a comprehensive search of peer-reviewed articles in three electronic databases: PubMed, Scopus, and Web of Science (published until May 2020). Studies were selected...
Effects of intermittent fasting on specific exercise performance outcomes: a sy...
Correia, Joana Margarida; Santos, Inês; Pezarat-Correia, Pedro; Minderico, Cláudia; Vilhena De Mendonca, GoncaloIntermittent fasting (IF) has been studied in athletes during Ramadan and in those willing to decrease adiposity while maintaining or increasing lean body mass. The purpose of this systematic review was to summarize the effects of IF on performance outcomes. We searched peer-reviewed articles in the following databases: PubMed, Web of Science and Sport Discus (up to December 2019). Studies were selected if they...
Trunk muscle activation during golf swing: Baseline and threshold
Silva, Luis; Marta, Sérgio; Vaz, João; Fernandes, Orlando; António, Maria; Pezarat-Correia, PedroThere is a lack of studies regarding EMG temporal analysis during dynamic and complex motor tasks, such as golf swing. The aim of this study is to analyze the EMG onset during the golf swing, by comparing two different threshold methods. Method A threshold was determined using the baseline activity recorded between two maximum voluntary contraction (MVC). Method B threshold was calculated using the mean EMG act...
