As we delve into the diverse applications of motion tracking from Space to Air and Land, we encounter distinct challenges and opportunities. However, the most significant arise in the aquatic domain, particularly in the maritime environment. The unique characteristics of water behaviour demand novel solutions for accurately tracking and interpretin...

Investigations of upper limb muscle activation during reach tasks available in the literature are not for rotator cuff injury. Yet, the small body of literature on upper limb muscle activation during these tasks does not include any systematic study on the influence of each shoulder test. Tests such as Belly press, Drop arm, Empty can, Full Can and...

Disclosed is inter alia an apparatus (63) for sensing a movement of an object (10, 11) relative to a fluid (12, 13), e.g. for sensing relative movements of a surf board in water. A particular characteristic of the invention is that the housing (21) is mounted in fixed arrangement to a surface (20) of the object, the housing receiving a spring membe...

Textile electrodes are an alternative to conventional silver-chloride electrodes in wearable systems. Their easy integration in garments and comfort provided to the user make them an interesting development of textile engineering. The potential of such electrodes to allow more unobtrusive data collection in health and sports context may enable the...

O Laboratório de Biomecânica do Porto (LABIOMEP-UP) é um centro de competências da Universidade do Porto dedicado ao ensino, investigação científica e tecnológica, inovação, prestação de serviços técnicos especializados e transferência de conhecimento e tecnologia em Biomecânica (humana e animal) de interesse ergonómico, clínico, desportivo ou biom...

The surf pop-up is a unique and challenging skill, critical to successful surfing. Hypothesizing that anthropometric characteristics of surfers influence the pop-up performance, we aimed to measure kinematics and ground-reaction forces (GRF) during a simulated pop-up motion, and to relate these variables with anthropometric characteristics. Twenty-...

Surfing is one additional sport proposed by the Tokyo 2020 Organizing Committee. Surprisingly, substantial efforts to understand surfing energetics are recent, and the impact of a single surfing paddling cycle on fatigue and energy cost is still not clear. Since surfing paddling technique is highly specific, experiments in real practice conditions...

We compared the hydrodynamic characteristics and pull-out strategies of four backstroke-to-breaststroke turning techniques in young swimmers. Eighteen 11 and 12-year-old swimmers participated in a 4 week intervention program including 16 contextual interference sessions. The hydrodynamic variables were assessed through inverse dynamics, and the pul...

In order to verify whether there is a considerable increase in body skin temperature during different swimming techniques (crawl and backstroke) and identifying the most affected regions. The athlete's thermal symmetry was also analyzed, as well as its modification after the swimming, according to the performed technique. The accuracy of thermograp...

Introduction Recently, kinematic analysis of the drinking task (DRINK) has been recommended to assess the quality of upper limb (UL) movement after stroke, but the accomplishment of this task may become difficult for poststroke patients with hand impairment. Therefore, it is necessary to study ADLs that involve a simpler interaction with a daily li...

Modern surfing has been described as an intermittent physical activity, which varies in duration and intensity, followed by considerable recovery periods. Currently, the analysis and judgment of surf sessions are based on empirical knowledge, experience, and observation. In other words, procedures that involve great measurement errors. However, it...

The aim of the present study was to determine which approach to calculating shoulder ratios is the most sensitive for determining shoulder torque imbalance in handball players. Twenty-six participants (handball athletes, n=13; healthy controls, n=13) performed isokinetic concentric and eccentric shoulder internal rotation (IR) and external rotation...

The athlete’s thermal symmetry was also be analyzed, as well as its modification after the swimming, according to the performed technique. The accuracy of thermog...

Introducción: el surf es una actividad deportiva con periodos de intensidades y duraciones variables que requiere de la activación simultanea y coordinada de diferentes sistemas sensoriales (visual, somatosensorial y vestibular) y de grupos musculares, con el fin de mantener el equilibrio encima de la tabla. Además en entrenamiento y en competición...

Introducción. La práctica deportiva del surf puede conllevar lesiones por traumatismo y por sobreutilización. Di-vidiendo el gesto deportivo durante la práctica en sus diferentes manifestaciones, encontramos dos características: la remada, que implica una carga sobre la articulación del hombro y la zona lumbar; y la puesta en pie (take-off), que pu...

Foot and hand set-up position effects were analysed on backstroke start performance. Ten swimmers randomly completed 27 starts grouped in trials (n = 3) of each variation, changing foot (totally immersed, partially and totally emerged) and hand (lowest, highest horizontal and vertical) positioning. Fifteen cameras recorded kinematics, and four forc...

Anthropometry has been widely used in different fields, providing relevant information for medicine, ergonomics and biometric applications. However, the existent solutions present marked disadvantages, reducing the employment of this type of evaluation. Studies have been conducted in order to easily determine anthropometric measures considering dat...

INTRODUÇÃO: O treinamento físico promove importantes respostas adaptativas no organismo que diminuem a morbidade e a mortalidade em hipertensos. Entretanto, são poucos os estudos que avaliaram a resposta pressórica do treinamento aeróbio de diferentes intensidades em hipertensos. Objetivo: Analisar os efeitos do treinamento físico aeróbio intenso c...

The pop-up is one explosive movement executed to stand up quickly on the surfboard. This movement defines the transition from the horizontal to vertical phase of surfing. After paddling the hands are supported in parallel on the surfboard, under the chest. An extension of the arms is held to promote a strong impulse to take-off, the feet are guided...

The concern about injuries in sport are evident due to the implications it carries. To have the knowledge of the mechanisms of injuries is important either to prevent and recovery. This context generates the appropriate scenario to develop an electronic solution to measure dynamically the Center of Pressure (CoP) and surfboard's movement and suppor...

WalkinSense is a new device designed to monitor walking. The aim of this study was to measure the accuracy and repeatability of the gait analysis performed by the WalkinSense system. Descriptions of values recorded by WalkinSense depicting typical gait in adults are also presented. A bench experiment using the Trublu calibration device was conducte...
