Objective: The present study aimed to investigate and to compare the electrophysiological changes in bipolar patients and healthy subjects during the execution of a saccade task. Materials and Methods: The subjects had to respond to a fixed visual stimulus presented by a LEDs bar. We executed an ANOVA (one-way) and post hoc Scheffé test to examine the difference of absolute alpha power and reaction time among four groups: control, depression, manic and euthymic. We observed the frontal, parietal and occipital regions. The paired t test was realized on each electrode and group to compare the pre and post moment in the task. Results: We observed a statistical difference among the groups for the behavioral variable—saccade reaction time. For the electrophysiological variable—absolute alpha power, we did not find significant difference between the moments (pre and post stimulus presentation) for none of the electrodes of each bipolar group. However, the results pointed out to a difference between the moments for F3, P3, O1 and O2 electrodes for control group. Conclusion: We cannot affirm that the task influences the cortical activity of the patients. It is possible that the method used to analyze the data is not the adequate. The time-frequency analysis could be better to analyze the present data. We also observed that the absolute alpha power could be considered a marker of bipolar disorder, but not of the different states (i.e., mania, depression, euthymia).

Previously,it was suggested that biological maturation(BM)could be linked to cardiac autonomic recovery(CAR)in the pediatric ***,this influence hasn’t been confirmed *** aim was to investigate the impact of BM on CAR in female volleyball *** study with a sample of 38 volleyball players,comprising 20 girls(age:[11.62.1]years)and 18 women(age:[24.55.5]years),we analyzed BM,comparing maturing subjects(girls)with mature subjects(women).Additionally,we assessed peak height velocity(PHV)in *** conducted a training session involving repeated sprints(3 rounds of 6 sprints interspersed by 5 min[min]of passive rest).Using short-range radio telemetry,we analyzed CAR during(at the end of the 1st and 2nd rounds)and after(following the 3rd round)the training session of repeated sprints by applying the 60-s to 300-s heart rate recovery index(HRR-Index).Girls exhibited superior CAR compared to women(round 2:60-s,120-s,240-s,and 300-s,p0.4,p0.4,p<0.05).We have concluded that biological maturation has a significant impact on cardiac autonomic recovery.

Sports and Public Space: volleyball Practice inCopacabana and Carcavelos/Cascais Beaches

The aim of this paper is to analyze volleyball practice in the beaches of Copacabana(Rio de Janeiro,Brazil)and Carcavelos and Cascais Bay(Cascais,Portugal)and to review the forms of appropriation of public space based on public policies and rules of the sport in *** methodology rests on bibliographic review and ethnographic research to map and distinguish the results in two spatial and cultural contexts that are considerably *** show that even with greater extension of Copacabana beach in comparison with Cascais,volleyball has a relevant impact in both *** installation of the necessary equipment for volleyball practice is also a form of impact in the landscape and establishment of territoriality,which is mainly activated when the game happens.
