- ItemSomente MetadadadosAnálise do estresse psicofisiológico e da correlação de marcadores de estresse durante a temporada de treinamento de atletas profissionais de futebol feminino(Universidade Federal de São Paulo (UNIFESP), 2017-11-16) Botelho, Renata [UNIFESP]; Guerra, Ricardo Luís Fernandes [UNIFESP]; http://lattes.cnpq.br/3856113753837921; Universidade Federal de São Paulo (UNIFESP)The aim of the study was to evaluate the correlations between internal training load (ITL), cortisol, creatine kinase (CK), heart rate variability (HRV) and mood states, and the behavior psychophysiological behavior, over a season of professional women's football professional training. Methods: Twenty-three professional female soccer players were evaluated in five moments of the season: baseline (M1), pre-season (M2), pre-competitive (M3), competitive 1 (M4) and 2 (M5). The instruments and procedures used were: profile of mood states (Brunel Humor Scale), salivary cortisol (SC), creatine kinase, heart rate variability and internal training load. SC was collected immediately after waking (CD) and at night (CN), and the other variables were evaluated in the morning (8 - 11 h). Results: the athletes presented psychophysiological changes throughout the training, which were observed by significant alterations in CK, CS, SDRR index and the Stress, Vigor and Fatigue scales, as well as total mood disturbance (p ≤ 0.05), concomitant with an CIT variation (p ≤ 0.05) throughout the study. The M2 and M3 periods were characterized by intensified CK values (p = 0.001; ES > - 1.31 - M2 and M3), CD (p = 0.007, ES > - 1.06 - M2 and M3), Fatigue (p ≤ 0.05 - M2 and M3) and SDRR index (p = 0.01 – ES = 0.80 - M3). In the M4 and M5 periods, significant decreases in CK (p = 0.001, ES > 1.05 - M4 and M5) were observed, CD (p = 0.024, ES = 0.81 - M4) M5) and Vigor (p = 0.01 M5). On the other hand, the SC showed a significant increase in these two periods (p = 0.001, ES > 0.99 - M4 and M5), concomitant with the increase in weekly ITL in M5 (p = 0.040; ES = - 0.32). In addition, the Tension and Vigor scales obtained positive correlations with SC (r ≥ 0.48) and SDRR index (r ≥ 0.43), respectively, and the Fatigue scale showed no correlation with any stress markers (p ≥ 0.05). Conclusion: the training season of female soccer players caused significant changes in the variables CK, SC, SDRR index and the Tension, Vigor and Fatigue scales. The lnRMSSD and LF/HF indices, and the Rage, Depression and Mental Confusion scales did not vary in the analyzed weeks. In addition, the Tension and Vigor scales obtained moderate and positive associations with SC and SDRR, respectively, and that varied over the periods. Monitoring of ITL and stress markers, analyzed by study is recommended in female soccer players to avoid the accumulation of stress caused by the training season.
- ItemSomente MetadadadosNeuropsychological Aspects Observed in a Nuclear Plant Simulator and Its Relation to Human Reliability Analysis(Springer Int Publishing Ag, 2017) Mendonca Pinheiro, Andre Ricardo; Pessoa do Prado, Eugenio Anselmo; Martins, Marcelo Ramos; Gomes, July Silveira [UNIFESP]; Droguett, Enrique LopezThis paper will discuss preliminary results of an evaluation methodology for the analysis and quantification of errors in manual (human) operation by training cognitive parameters and skill levels in the complex control system operation based on Neuropsychology and Psychophysiology approaches. The research was conducted using a game (nuclear power plant simulator) that simulates concepts of operation of a nuclear plant with a split sample evaluating aspects of learning and knowledge in the nuclear context. Operators were monitored using biomarkers (ECG, EEG, GSR, face detection and eye tracking) and the results were analyzed by statistical multivariate techniques. The experiments aimed at observing state change situations such as shutdowns and planned matches, incidents assumptions and ordinary features of operation. The preliminary findings of this research effort indicate that neuropsychological aspects can contribute to improve the available human reliability techniques by making them more realistic both in the context of quantitative approaches for regulatory purposes as well as in reducing the incidence of human error.
- ItemAcesso aberto (Open Access)Relação entre estados de humor, variabilidade da frequência cardíaca e creatina quinase de para-atletas brasileiros(Universidade Estadual de Maringá, 2013-03-01) Leite, Gerson dos Santos; Amaral, Daniel Pereira do; Oliveira, Raul Santo de; Winckler, Ciro [UNIFESP]; Mello, Marco Tulio de [UNIFESP]; Brandão, Maria Regina Ferreira; Universidade Nove de Julho; Universidade São Judas Tadeu; Universidade Federal de São Paulo (UNIFESP)The main purpose of this study was to check any relationship between mood states heart rate, variability (HRV) and creatine kinase (CK) of Brazilian para-athletes. Were evaluated 12 athletes, members of the Brazilian Team of Para-Athletics. In order to evaluate the autonomic response the HRV of athletes was determined at rest, by collecting the R-R intervals within 10 min. It was also collected blood samples to analyze the total CK, and the Brums scale was applied to know the mood states of the athletes, being calculated the six mood states (tension, depression, anger, fatigue, confusion and vigor). Analysis of the data was performed by Spearman correlation. The main results indicated a relationship between the parasympathetic modulation and the Vigor of the athletes (r = 0.50 to 0.53; p<0.05). The CK was not related with any marker. In conclusion: There was a relationship between the parasympathetic modulation of HRV and the Vigor, which is good for the performance.
- ItemSomente MetadadadosRelações entre estados de humor, percepções subjetivas, creatina quinase e saltos verticais de para-atletas ao longo de um ciclo de treinamento(Universidade Federal de São Paulo (UNIFESP), 2017-03-17) Uehbe, Carol [UNIFESP]; Winckler, Ciro [UNIFESP]; http://lattes.cnpq.br/2067947156482139; Universidade Federal de São Paulo (UNIFESP)The aims of this study were to analyze the relationships between vertical jumps, CK, subjective perceptions of effort and recovery and mood states throughout a cycle of training of Paralympics athletes from traCK and field and how these variables behave in each week and between the training weeks evaluated. For this, 17 athletes of the Brazilian Paralympic athletics team were evaluated and separated into groups: 7 athletes with visual impairment (DV), 2 athletes with cerebral palsy (CP), 3 athletes with lower limb or superior amputation (AMP), 5 athletes guides (GUIDE), and the General group, with all athletes together in a single group. The mood states were evaluated by the Brunel Humor Scale (BRAMS), the Subjective Effort Perception (PSE) - the Cavasini scale - and the Subjective Recovery Perception (PSR). As a biochemical marker, the measurement of Creatine Kinase (CK) was used and the vertical jumps used were Squat Jump (SJ) and vertical jump with countermovement (CMJ). All of these tests were performed in 3 different weeks of training, with the interval of approximately 3 months between each, totaling 6 months in total. The tests were always performed on the second (pre) and Friday (post) of each week, except for the PSE that was performed only on Friday and the BRAMS that was performed once during the week. The results show that in the DV Group, PSR decreased at the end of week 1 compared to the beginning of this week; The CKpré decreased at week 2 compared to week 1 and the CMJpre increased at week 3 compared to week 2. In the GUIDES group, the CMJ increased at the end of the week compared to the beginning at weeks 2 and 3. In the General group, PSR decreases at the end of weeks 1 and 3 compared to the beginning of the weeks. The CMJpre increased at week 3 compared to week 2 and CMJ post increased at week 2 compared to 1; The pre and post CK decreased at week 2 compared to week 1. In the results in the PC and AMP groups, it was difficult to notice a pattern of results since these were individual. Nevertheless, in these two groups the results did not change much of those found in the other groups. In the correlation of the variables, during the 3 weeks, the mood Vigor showed a positive correlation with post PSE and PSRpost; Angry with PSR post and Depression with the CMJpré. CK showed correlation with all jumps. As for the model created to analyze the impact of the variables on the jumps, the PSR post and the PSE post impacted negatively on the CMJ post, the depression positively impacted on the pre-CMJ and the CK pre-positively on all the jumps. From these data, it was concluded that CMJ, CK and PSR were the variables that showed the greatest changes throughout the training in all groups. On the other hand, the states of humor, Squat Jump and the subjective perception of effort did not vary during the analyzed period. Besides that, these variables demonstrated to relate different forms during the training period analyzed.
