“…Manual aiming movements were quantified using a Wacom The motor task and procedures used in previous studies were also used in this study 3,11,12 . The participants were required to make fast and accurate strokes (displayed in real time on the laptop monitor) from the home position to the target.…”

“…The Kolmogorov-Smirnov Test showed that the PV violated the assumption of normal distribution under control and higher indexes of conditions, as well as the ND in the control condition, but the data were normalized by a logarithmic transformation (log10). The same inferential analyses applied by Lage et al, 3 were used. Student's t test for independent samples for groups were conducted.…”

“…Peak velocity is used as the main kinematic marker to distinguish the initial impulse phase (primary submovement) and the final homing phase (secondary submovement) 3 . The time interval preceding peak velocity (primary submovement) reflects the preprogrammed phase of the movement.…”

“…The responsestyle hypothesis 8,10 assumes the manifestation of sex-specific response strategies when the sensory motor system is challenged by different task constraints. Evidently, biomechanical factors differ between men and women, but when the same mechanical aspects of the movement are maintained and different cognitive processes are required, the difference between sexes in aiming movements becomes related to mental proceIn previous studies, we employed an aiming task that simulated different cognitive and motor constraints observed daily under manual control 3,11,12 . This task seems to be an interesting form of investigating other types of task constraints that can influence the control strategies in women and men.…”

-Aims:This study aimed to investigate the comparison between sex and manual aiming control in different cognitive and motor constraints of the task. Methods: Eighty-four right-handed participants (42 women) performed 110 trials of a manual aiming task with a non-inking pen on a digitizing tablet. The aiming task required four different conditions of execution. The control condition appeared on the computer screen in 70% of the trials, and the other three conditions, (a) distractor, (b) inhibition of response and (c) higher index of difficulty, each appeared in 10% of the trials. Results: Compared with women, men produced shorter movement and response times, as well as higher peak velocity in the control and distractor conditions. When the index of difficulty of the task increased, men produced only higher peak velocity. Women produced more corrective movements to achieve the target only in the control condition. Conclusion: Our results corroborate those of previous studies that indicate sex-specific response strategies when the sensory motor system is challenged by different task constraints.

“…Quanto maior o escore, maior a frequência de checagem corporal. As atletas foram divididas em três grupos em função dos escores do BCAQ: alta (33,3% mais altos), média e baixa (33,3% mais baixos) frequência de checagem corporal, metodologia já utilizada por Lage et al (2012). Para a presente amostra foi identificada consistência interna de 0,86.…”

RESUMOO objetivo do estudo foi analisar a relação da checagem corporal com a restrição alimentar em atletas do sexo feminino. Participaram 97 atletas de ginástica artística, atletismo e natação com idade igual ou superior a 12 anos. Utilizou-se o Body Checking and Avoidance Questionnaire (BCAQ) para avaliar a frequência de checagem corporal. Para avaliar a restrição alimentar foi aplicada a subescala "Dieta" do Eating Attitudes Test (EAT-26). Para avaliar a insatisfação corporal foi aplicado o Body Shape Questionnaire. Os achados demonstraram relação da insatisfação corporal com a subescala Dieta (F(1, 96)=24,33; R²=0,51; p=0,001). Por fim, evidenciou-se relação do BCAQ com a subescala Dieta (F(1, 96)=19,56; R²=0,54; p=0,001). Concluiu-se que a checagem corporal está diretamente relacionada à restrição alimentar em atletas do sexo feminino.Palavras-chave: Transtornos alimentares. Imagem corporal. Atletas.
