  • Accuracy of Hidden Markov Models in Identifying Alterations in Movement Patterns during Biceps-Curl Weight-Lifting Exercise
    Publication . Peres, André B.; Espada, Mário; Santos, Fernando Jorge Lourenço Dos; Robalo, Ricardo A. M.; Dias, Amândio A. P.; Muñoz-Jiménez, Jesus; Sancassani, Andrei; Massini, Danilo A.; Filho, Dalton M. Pessôa
    This paper presents a comparison of mathematical and cinematic motion analysis regarding the accuracy of the detection of alterations in the patterns of positional sequence during biceps-curl lifting exercise. Two different methods, one with and one without metric data from the environment, were used to identify the changes. Ten volunteers performed a standing biceps-curl exercise with additional loads. A smartphone recorded their movements in the sagittal plane, providing information on joints and barbell sequential position changes during each lift attempt. An analysis of variance revealed significant differences in joint position (p < 0.05) among executions with three different loads. Hidden Markov models were trained with data from the bi-dimensional coordinates of the joint positional sequence to identify meaningful alteration with load increment. Tests of agreement tests between the results provided by the models with the environmental measurements, as well as those from image coordinates, were performed. The results demonstrated that it is possible to efficiently detect changes in the patterns of positional sequence with and without the necessity of measurement and/or environmental control, reaching an agreement of 86% between each other, and 100% and 86% for each respective method to the results of ANOVA. The method developed in this study illustrates the viability of smartphone camera use for identifying positional adjustments due to the inability to control limbs in an adequate range of motion with increasing load during a lifting task.
  • A motivação para prática de actividades desportivas em praticantes federados de basquetebol e atletismo

    O presente estudo pretende estudar a motivação para a prática de atividade despor-tivas em praticantes federados de basquetebol e atletismo.A amostra foi constituída por 81 jovens praticantes (n=35 de basquetebol e n=46 de atletismo). O instrumento utilizado para a recolha dos dados foi o Questionário de Motivação para as Ativida-des Desportivas (QMAD). A análise de dados foi feita através da estatística descri-tiva. Os resultados demonstram que os atletas inquiridos centram as suas motivações no trabalho em equipa(afiliação específica), fazer coisas em que se é bom(estatuto), ser reconhecido e ter prestígio (estatuto),entrar em competição (competição)e des-carregar energias(emoções). De acordo com os resultados, podemos concluir que uma vez que os atletas são federados, foi visível uma maior motivação extrínseca, estando mais orientada para o ego.

  • Physiological and physical effect on U-12 and U-15 football players, with the manipulation of task constraints: field size and goalkeeper in small-sided games of 4x4 players

    Our study aimed to verify whether the task constraints manipulation has different effects according to age group. Another objective was to verify the physiological and physical responses in the different formats of small-sided games (SSG). Each team in the SSGs was composed of 4 players (4x4). The participants in the research were young football players U-12 (n=8) and U-15 (n=8), affiliated with a club certified as a training entity, and competing, respectively, in the 7 and 9-a-side regional football championships and the national championship of Portugal. The internal and external load data was collected in 5 formats of SSGs with three field sizes and in 2 used goalkee pers. We used the WIMU PROTM inertial device for data collection. The registration of the internal charge, using heart rate (HR), was performed with the use by the players of Garmin bands, which send the data to WIMU PROTM devices, through of Ant+ technology. The variance analysis (ANOVA) was used to verify the differences between SSGs and the effect size was determined by calculating partial eta-square . Comparisons between the two age groups were evaluated using standardized differences with combined variance(Cohen’s d). The results show that the manipulation of the playing areas and the use of goalkeepers participation promoted different effects in the two age groups in terms of distance, explosive distance, accelerations/decelerations and maximum sprint. As for the comparison between SSGs we found differences in the level of external load (distance, accelerations/decelerations and maximum sprint). At the level of internal load, the effects were more evident with field areas above 100m2. We can conclude that the task constraints manipulation, playing area and goalkeeper participation, promote different physical and physiological responses, and the coach should consider this fact, as well as the effects promoted in the age groups.
