However, there is less clarity surrounding the effect of exercise-induced fatigue on attention network particularly in those with a history of continuous physical activity.AimsThis research was aimed to determine whether exercise-induced fatigue can affect cognitive functions, especially those involved in attentional control (i.e., alerting, orientation, and executive functions) and to identify any differences in attentional control between active and inactive individuals after exercise-induced fatigue.MethodsWe compared the performance of 24 physically active and inactive participants in the Attentional Network Task, which allows for the assessment of the executive, orienting and alerting networks. Under two conditions regarding exercise-induced fatigue (pre-fatigue and post-fatigue), we used sub-maximum aerobic endurance training to...

Considering the effect of socio-economic status (SES) in relation to the MP of adolescents with DCD, it is necessary to examine this issue further. The purpose of this study was to investigate the effect of Karate-Do interventions on the MP of adolescents with DCD from high/low SES.MethodsParticipants included 16 adolescent girls (12 to 13 years old) with DCD, and their classification into high/low SES groups was done by using appropriate previously validated questionnaire. A short form of the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2), was used to assess fine motor precision, fine motor integration, manual dexterity, upper limb coordination, bilateral coordination, balance, strength, speed, agility, and overall MP level of the participants. Both high/low-SES groups completed a spec...

Participants in this study were 584 adolescent girls and boys (aged 15 on average) from Tehran, Isfahan and Ghazvin provinces of Iran. Measurement tools for the study included Ryckman's physical Self-Efficacy Questionnaire, Duda's Goal Orientation Questionnaire and Motl's Questionnaire of Physical Activity Enjoyment. For data analysis, Pearson's correlation coefficient, multivariate ANOVA and multivariate regression were used (P<0.05). Findings of the study showed positive significant correlation between perceived physical ability, Physical Self-Presentation Confidence, task-orientation, ego-orientation with enjoyment of physical activity. In the micro-scale of physical activity enjoyment, significant difference was observed between girls and boys. Results of multivariate...

Performing these activities depends on many factors such as sensory and attentional features. The purpose of this study was to investigate the effect of sensory disturbance and cognitive load on time of the relative phase transition in anti-phase bimanual coordination pattern among elderly women. Materials and Methods: Twelve right-handed healthy old women (66.0 ± 2.8 years old) of the twenty four voluntaries were selected based on the inclusion criteria in this study. Participants started their movement on bimanual coordination device with anti-phase pattern at the frequency of 0.50 Hz .Then, after each five seconds, 0.25 Hz was gradually increased to frequency and continued until the anti-phase pattern turned to in-phase pattern. This task was performed in two different conditions concluding with cognitive load and without it with the dis...
