Recommendations for the implementation of a national lung cancer screening prog...
Fernandes, M. G. O.; Dias, M.; Santos, R.; Ravara, S.; Fernandes, P.; Firmino-Machado, J.; Antunes, J. P.; Fernandes, O.; Madureira, A.; Hespanhol, V.Lung cancer (LC) is a leading cause of cancer-related mortality worldwide. Lung Cancer Screening (LCS) programs that use low-dose computed tomography (LDCT) have been shown to reduce LC mortality by up to 25 % and are considered cost-effective. The European Health Union has encouraged its Member States to explore the feasibility of LCS implementation in their respective countries. The task force conducted a com...
The Effect of Expertise during Simulated Flight Emergencies on the Autonomic Re...
Santos, S.; Parraca, J.A.; Fernandes, O.; Villafaina, S.; Clemente-Suarez, V.J.; Melo, F.Heart rate variability (HRV) and performance response during emergency flight maneuvers were analyzed. Two expert pilots (ages 35 and 33) and two rookie pilots (ages 25) from the Portuguese Air Force participated in this case–control report study. Participants had to complete the following emergency protocols in a flight simulator: (1) take-off engine failure, (2) flight engine failure close to the base, (3) fl...
The Efficacy of LUCAS in Cardiac Arrest
Alves, A.I.; Freitas, C.; Viveiros, A.; Ribeiro, L.; Veríssimo, M.; Fernandes, O.Introduction: Chest compression is the basic technique of cardiopulmonary resuscitation (CPR) in patients with cardiac arrest. The quality and early performance of CPR is critical to improve the prognosis and chances of restoring spontaneous blood flow. Today we have manual compressions and mechanical chest compression devices. Objective: The aim of this study is to clarify the importance of the LUCAS system (T...
Effects of whole body vibration exercise on muscle strength and dynamic balance...
Vieira, I.; Fernandes, O.; Raimundo, A.; Parraca, J.A.; Batalha, N.; Tomas-Carus, P.Introduction: One of the major causes generating disability and even death among the elderly population are the falls, and as such a major public health problem (Bogaerts, Delechulse, Boonen, Claessens, Milisen & Verschueren, 2011). There are several studies that show that the Whole Body Vibration (WBV) can be a reliable alternative to many other types of training to reduce the risk of falls of the elderly, by ...
Intra- and inter-group coordination patterns reveal collective behaviours of fo...
Duarte, R.; Araújo, D.; Fernandes, O.This study examined emergent coordination processes in collective patterns of behavior in 3 vs 3 sub-phases of the team sport of association football near the scoring zone. We identified coordination tendencies for the centroid (i.e., team center) and surface area (i.e., occupied space) of each sub-group of performers (n = 20 plays). We also compared these kinematic variables at three key moments of play using m...
The influence of a balance training program on the electromyographic latency of...
Dias, A.; Esteves, P.; Fernandes, O.; Pezarat-Correia, J.BACKGROUND: Balance training is often employed for the prevention of ankle injuries. However, until now, most of the studies have focused on the prevention of a recurrent injury. The objective of this study was to look into the effects of balance training on the onset of peroneal muscle activity in healthy subjects. METHODS: 34 participants (mean age = 19.5 years +/- 1.5; height = 1.70 m +/- 0.12; weight = 62.0...
Proximity-to-goal as a constraint on patterns of behaviour in attacker-defender...
Headrick, J.; Renshaw, I.; Araujo, D.,; Passos, P.; Fernandes, O.; Davids, K.Abstract The aim of this study was to determine whether spatiotemporal interactions between footballers and the ball in 1 vs. 1 sub-phases are influenced by their proximity to the goal area. Twelve participants (age 15.3 +/- 0.5 years) performed as attackers and defenders in 1 vs. 1 dyads across three field positions: (a) attacking the goal, (b) in midfield, and (c) advancing away from the goal area. In each po...
Kinematic and electromyographic analyses of a karate punch
VencesBrito, A. M.; Rodrigues Ferreira, M.; Fernandes, O.; Pezarat-Correia, P.; Cortes, N.The aims of this study were: (i) to present the kinematic and electromyographic patterns of the choku-zuki punch performed by 18 experienced karatekas from the Portuguese team, and (ii) to compare it with the execution of 19 participants without any karate experience. The kinematic and electromyographic data were collected from the arm and forearm during the execution of the specific punch. A two-way analysis o...
Observação do comportamento em nadadoras gémeas em 200m bruços: implicação musc...
Conceição, Ana T.; Silva, A.J.; Barbosa, Tiago M.; Fernandes, O.; Louro, HugoO objectivo deste estudo consistiu na observação do comportamento técnico em nadadoras gémeas, através da análise dos parâmetros neuromusculares na técnica de bruços. A electromiografia de superfície (EMG) foi utilizada para analisar a dinâmica da actividade neuromuscular nos músculos pectoralis major(PM), bíceps brachii(BB), tríceps brachii(TB), deltoid anterior(DA) e latissimus dorsi(LD) no lado direito do co...
Rotator cuff isokinetic strength of young group aged swimmers in a competitive ...
Sousa, J.P.; Batalha, N.; Raimundo, A.; Belfo, M.; Munoz, D.; Tomas-Carus, P.; Fernandes, O.Introduction: In any given sports activity, muscular or movement instability is pointed out as having a high influence for the maintenance of correct joint functionality. In swimming, due to the repetitive use of shoulder muscles, there is a higher tendency to promote injuries at the shoulder joint, especially when instability between the internal (IR) and external (ER) shoulder rotators is present. The aims of...
