Relationships between head-out aquatic exercise kinematics and musical cadence: analysis of the side kick

Background: Head-out aquatic exercises became one of the most popular physical activities within the health primarily and thirdly prevention system. Music is seen as one of the most important aspects when conducting head-out aquatic exercise sessions. Research question: Is there any relationship between musical cadence and the kinematic behaviour when performing aerobic head-out aquatic exercises? It was hypothesized that an increase in music cadence will would impose a decrease of the segment range of motion. Type of study: Experimental, prospective. Methods: Six young and clinically healthy women with at least one year of experience conducting head-out aquatic classes were videotaped in the frontal plane, with a pair of cameras providing a double projection (above and below the water surface). Subjects performed an incremental protocol of five bouts (120b.min-1, 135b.min-1, 150b.min-1, 165b.min-1 and 180b.min-1) with 16 full cycles of the “side kick” exercise. Data processing and calculation of segmental (i.e. hands and feet) and anatomical landmark (i.e. centre of mass) were performed using the software Ariel Performance Analysis System and applying the DLT algorithm. Results: There was a decrease in the cycle period during the incremental protocol. The relationships between the segmental lateral and vertical displacements with the musical cadence were not significant. The segmental velocities on the lateral and vertical components showed significant increases throughout the incremental protocol. Conclusions: The data suggest that segmental velocity increases with increasing cadence, reducing the cycle period and maintaining the segmental displacements

Head-out aquatic exercise “sailor’s jigs” kinematics at increasing musical cadence

The aim of this study was to analyze the relationships between “Sailor’s jigs” kinematic and increasing music cadence. Six young women with at least one year of experience conducting this type of head-out aquatic programs, with no kind of skeletal muscle injury reported on the last six months and non-pregnant were evaluated. The exercise was recorded on video, in the frontal plane, using a pair of cameras, enabling a double projection, from above and underwater body motions, at five increasing cadences (120 b.min-1, 135 b.min-1, 150 b.min-1, 165 b.min-1 and 180 b.min-1). Images were thereafter digitized in specific software (Ariel Performance Analysis Systems). The cycle period decreased through the incremental protocol. Cycle period decrease is done decreasing joints range of motion and increasing the limbs segmental velocity as well. Although these combined kinematical strategy, a deeper analysis reveals that subjects decrease the cycle period mainly decreasing the range of motions

Kinematical characterisation of a basic head-out aquatic Exercise during an incremental protocol

The aim of this study was to analyze the relationships between musical cadence and kinematical characteristics of a basic head-out aquatic exercise. Six young women with at least one year of experience conducting head-out aquatic classes were videotaped in the sagital plane with a pair of cameras providing a dual projection from both above and underwater performing 5 incremental bouts (120, 135, 150, 165 and 180 b.min-1) of the basic head-out aquatic exercise “rocking horse”. There was a decrease of the cycle period throughout the protocol. Relationships between horizontal or vertical displacements with music cadence were not significant. Increased cadence imposed increased segmental and centre of mass’ velocities. As a conclusion expert and fit subjects seem to increase segmental velocity with increasing musical cadence

Kinematical characterization of the basic head-out aquatic exercise “Sailor’s Jigs”

Massive research has been produced throughout the last decades in order to be@er understand the role of head-out aquatic exercises in populations’ health (Barbosa et al, 2009). Indeed, such studies aimed to characterize the physiological acute and/or chronic response of subjects performing head-out aquatic exercises. Moreover, the comprehensive knowledge about the biomechanical (i.e. kinematical) behavior performing this aquatic actvity is quite reduced.info:eu-repo/semantics/publishedVersio

Desenvolvimento de Sistema de Odontologia –Módulo Contas a Pagar e Receber: Odonto Clínica ERP

O trabalho descrito neste relatório é sobre desenvolvimento de sistema de informação que possui a função de informatizar uma clínica odontológica de acordo com suas principais necessidades. O sistema, Odonto Clínica ERP é um Projecto desenvolvido na empresa Ada Soluções que tem como objectivo melhorar o atendimento aos pacientes da clínica, garantindo agilidade e facilidade aos seus utilizadores na consulta e documentação de seus serviços. O Odonto Clínica ERP, módulo “ contas a pagar e receber” é um sistema simples e eficiente que garante às clínicas odontológicas o controlo de todos os pagamentos efectuados pela clínicas e das contas a receber dos pacientes. O documento possui informações sobre o sistema, os requisitos do sistema, diagramas para a implementação dos requisitos do sistema e visualização dos conceitos de sistema de informação, descrição da base de dados que armazenará os dados do sistema e sobre a modelação do sistema. Várias abordagens teóricas foram adoptadas para a realização desse sistema, privilegiando os conhecimentos adquiridos durante a formação académica. Para o desenvolvimento desse sistema utilizou-se a plataforma Oracle Application Express 10g com a linguagem de programação PL/SQL, e para fazer a modelação do sistema foi usada a ferramenta Visual Paradigm for UML 6.0. Esse sistema foi dividido em sete módulos, por isso, o presente relatório vai focar no módulo de Contas a pagar e receber da clínica

Caracterização cinemática do movimento básico de hidroginástica "polichinelo" a diferentes ritmos de execução

O estudo teve como objectivo analisar as relações entre a cadência musical e as características cinemáticas de um movimento básico de Hidroginástica. Cinco mulheres jovens com pelo menos um ano de experiência na condução de aulas de Hidroginástica foram filmadas no plano sagital por um par de câmaras, permitindo uma projecção dupla e simultânea de imagens (superfície e subaquática). As mesmas foram obtidas durante a execução do movimento básico “Polichinelo” ao longo de 5 patamares com intensidade crescente (120 b.min-1, 135 b.min-1, 150 b.min-1, 165 b.min-1, 180 b.min-1). Verificou-se uma diminuição do período de ciclo ao longo do protocolo incremental. A cadência musical apresentou uma relação significativa com o deslocamento vertical do centro de massa e da mão. O incremento da cadência induziu um aumento da velocidade lateral do pé. Desta forma, sujeitos experientes na execução do exercício básico de Hidroginástica “Polichinelo” parecem aumentar a velocidade de execução para assim manter o deslocamento dos segmentos inferiores (i.e., pés) com ênfase nos movimentos latero-mediais. No entanto, a mesma opção não se verifica relativamente ao centro de massa e para os segmentos superiores (i.e., mãos) com ênfase na componente vertical onde o deslocamento é diminuído com o intuito de manter a sincronização do movimento com a cadência musica
