Rostos que questionam a identidade feminina
Conceição, AnaA identidade constitui um tema recorrente na sociedade contemporânea, assim como na arte, uma vez que o indivíduo se depara com uma abundância de possibilidades que dificulta a adoção de uma única identidade. O presente artigo pretende explorar a identidade feminina através de retratos pela artista Jenny Saville. Depois de se iniciar com uma introdução abrangente ao tema, o método aplicado neste trabalho consis...
Kinematic and neuromuscular responses to different visual focus conditions in s...
Freitas, João; Conceição, Ana; Stastny, Jan; Morais, J. E.; Marques, Diogo L.; Louro, Hugo; Marinho, D.A.; Neiva, Henrique P.This study analyzed the kinematics and muscle activity during the stand-up paddleboarding (SUP) under different visual focus points in three conditions: i) eyes on the board nose, ii) looking at the turn buoy, and iii) free choice. Methods: Fourteen male paddleboarders (24.2 ± 7.1 years) performed three trials covering 65 m, and the electromyographic (EMG) activation patterns and kinematic parameters in four cy...
The Effect of Handlebar Height and Bicycle Frame Length on Muscular Activity du...
Conceição, Ana; Milheiro, Vítor; Parraca, José A.; Rocha, Fernando; Espada, Mário C.; Santos, Fernando J.; Louro, HugoThe cycling literature is filled with reports of electromyography (EMG) analyses for a better understanding of muscle function during cycling. This research is not just limited to performance, as the cyclist’s goal may be rehabilitation, recreation, or competition, so a bicycle that meets the rider’s needs is essential for a more efficient muscular activity. Therefore, the purpose of this study was to understan...
Electromyographic analysis of deadlift for construction workers
Machado, Renato; Branco, Marco; Conceição, Ana; Rocha, Fernando; Louro, HugoWorking in construction is physically demanding. The tasks inherent to this professional occupation physically wear workers down, leaving them at a high risk of injury, mainly in the shoulder and knee joints and the lumbar region (Chung et al., 2019; Umer et al., 2018). Those tasks require a great balance capacity and strength of the postural muscles, with the Construction Workers (CW) supporting heavy equipmen...
Detraining and retraining effects from a multicomponent training program on the...
Leitão, Luis; Campos, Yuri; Louro, Hugo; Figueira, Ana Cristina Corrêa; Figueiredo, Teresa; Pereira, Ana; Conceição, Ana; Marinho, Daniel A.Background: Resuming a physical exercise program after a period of cessation is common in older women. Monitoring the responses during this detraining (DT) and retraining (RT) may allow us to analyze how the body reacts to an increase and a reduction in physical inactivity. Therefore, we conducted a follow-up training, DT, and RT in prehypertensive older women to analyze the response to these periods. Methods: ...
Biomechanical analysis of technical actions used in the 2021 European Judo Cham...
Batista, Marco; Conceição, Ana; Sombra, Katia; Petrica, João; Serrano, João; Honório, Samuel; Louro, Hugo Gonçalo DuarteIn Judo, each motor action depends greatly on the behavioural and technical variability of each judoka, which largely determines the options and the predominance of biomechanical actions inherent to the movements themselves. It is, therefore, important to understand the biomechanical action trends implemented by judokas in the dynamics of current judo, allowing for more assertive competitive preparation. The ob...
Predominant technical actions used in the European judo championship
Batista, Marco; Silva, Carlos; Torres, Diana; Conceição, Ana; Borrego, Carla; Louro, Hugo Gonçalo DuarteJudo is an Olympic combat sport that is divided into male and female weight categories. Each weight category implies significant differences in technical and strategic dimensions, as well as physiological, performance, and body composition among com- petitors. This study aimed to determine the technical actions predominance used by judokas in the European Judo Championship 2021. We observed 398 judo combats, in...
Intra- and inter-individual variability in the underwater pull-out technique in...
Gonjo, Tomohiro; Olstad, Bjørn; Stastny, Jan; Conceição, Ana; Seifert, LudovicThe purpose of the present study was to investigate the intra- and inter-individual variability in arm-leg coordination during the underwater phase of the turn segment in 200 m breaststroke. Thirteen male swimmers were recruited and performed a 200 m breaststroke in a pre-calibrated 25 m pool. Sub-phases during the underwater segment were obtained using a notational analysis, and the mean velocity, displacement...
Neuromuscular assessment of a stand-up paddle stroke
Freitas, João; Conceição, Ana; Šťastný, Jan; Louro, Hugo; Leitão, Luís; Torres, Diana; Marinho, Daniel A.; Neiva, Henrique P.his study analyzed muscle activity during the stand-up paddle stroke, considering the paddling side and the adjacent and opposing muscles relative to the position of the arms during paddling. Methods: Fourteen male paddleboarders performed three trials covering 195 m in which surface electromyography of the upper trapezius, biceps brachii, triceps brachii, tibialis anterior, and gastrocnemius medialis were reco...
A systematic review for stand-up paddle: a review in stand-up paddle
Freitas, João; Conceição, Ana; Louro, Hugo; Forte, Pedro; Marinho, Daniel A.; Neiva, Henrique P.The goal is to investigate how the length and height of passes impact a team's performance in national championships. A predictive model will be developed to analyse the success of different pass characteristics, including short, medium, and long length and ground, low, and high height. The model will be based on the points earned and will determine which combination of pass characteristics is most effective. O...
