- Analysis of the backpack loading efects on the human gaitPublication . Machado, Leandro; Castro, Marcelo P. de; Abreu, Sofia; Sousa, Helena; Gonçalves, Pedro; Sousa, Filipa; Santos, Rubim; Pinto, Viviana; Vaz, Mário; Vilas-Boas, João P.Gait is a simple activity of daily life and one of the main abilities of the human being. Often during leisure, labour and sports activities, loads are carried over (e.g. backpack) during gait. These circumstantial loads can generate instability and increase biomechanicalstress over the human tissues and systems, especially on the locomotor, balance and postural regulation systems. According to Wearing (2006), subjects that carry a transitory or intermittent load will be able to find relatively efficient solutions to compensate its effects.
- Analysis of the backpack loading effects on the human gaitPublication . Machado, Leandro; P. de Castro, Marcelo; Abreu, Sofia; Sousa, Helena; Gonçalves, Pedro; Sousa, Filipa; Santos, Rubim; Pinto, Viviana; Vaz, Mário; Boas, J. Paulo VilasGait is a simple activity of daily life and one of the main abilities of the human being. Often during leisure, labour and sports activities, loads are carried over (e.g. backpack) during gait. These circumstantial loads can generate instability and increase biomechanical stress over the human tissues and systems, especially on the locomotor, balance and postural regulation systems. According to Wearing (2006), subjects that carry a transitory or intermittent load will be able to find relatively efficient solutions to compensate its effects. These are dependent upon the walking distance and of the load characteristics - size, weight and location relatively to the body (Hsiang, 2002).Thus, these solutions should become a concerning factor (Koh, 2009) and a topic of scientific research, particularly in what concerns the inventory of its biomechanical effects and the possible strategies to be developed in order to minimize its effects. The aim of the present study was to analyze the effects of an occasional dorso-lombar load during the gait through the use of a backpack.
- Efeito da sobrecarga permanente e ocasional nos parâmetros cinéticos da marchaPublication . Castro, Marcelo; Abreu, Sofia; Sousa, Helena; Figueiredo, Cristina; Machado, Leandro; Santos, Rubim; Vilas-Boas, João PauloProposta do presente estudo foi comparar o efeito da sobrecarga permanente (pessoas obesas) e ocasional (mochileiros) nos parâmetros cinéticos da marcha. Foram observadas adaptação no padrão da marcha nos indivíduos quando submetidos a sobrecarga.
- The influence of differente speeds on backpacker's gait kinecticsPublication . Castro, Marcelo Peduzzi; Abreu, Sofia; Sousa, Helena; Figueiredo, Cristina; Machado, Leandro; Santos, Rubim; Vilas Boas, JoãoThis study analyzed the influence of different speeds on ground reaction force’s (GRF), impulses and mean vertical force during gait of people submitted to occasional overload (backpack). A force plate was used to record the GRF data of 60 young adult subjects walking in two different cadences: 69 steps/min (slow gait) and 120 steps/min (fast gait). During the slow gait, the impact and propulsive impulses of vertical GRF, propulsive impulse of anterior-posterior GRF, impulse of medial-lateral GRF and duration of stance phase were larger than during the fast gait; the mean vertical force was the only variable that showed larger values during fast gait. Therefore, slow gait may present a larger possibility of blister development and gait unbalance, while the fast gait, even presenting a small impulse, seems to be more harmful to the musculoskeletal system.
