Item Efeitos da indução de estresse mental na variabilidade da frequência cardíaca em atletas de Badminton(Universidade Brasil, 2021) Carvalho, Jane Maria Silva; Navarro, Ricardo ScarparoThe objective of the study was to analyze the effects of mental stress induction on heart rate variability in Badminton athletes. The study is direct, descriptive, experimental, cross-sectional and quantitative, carried out with the 15 highest ranked in the State of Piauí, by the Brazilian Confederation of Badminton, in January 2019. The sample consisted of 8 women and 7 men, with the average age of 19 years-old (+2.85), where the majority belonged to the main category (53.33%), participated in international competitions (66.66%) in all modalities (80%). The athletes were submitted to a previous anamnesis, measurement of blood pressure (BP), evaluation of HRV and Computerized Stroop Test. The procedures started with the placement of the Polar® H10 transmitter for the evaluation of the HRV in the participants, who went through a 5 min adaptation moment, when their BP was measured. After another 5 minutes of rest and BP measurement again, the Stroop Test of TESTIPACS® was then applied and the HRV evaluation was completed. For the analysis of HRV, the intervals were fragmented into 1 min, so that possible changes in the signals could be observed and only the resting moment and application of the Stroop Test were considered. All procedures were approved by the Ethics and Research Committee of Centro Universitário Uninovafapi (PI) (#3147702). It can be observed that the stressful stimulus promoted an increase in the mean HR and a decrease in the mean of the RR intervals, which suggests a physiological response that reflects the activation of the cardiac autonomic function, also perceived in the reduction of the SDNN, RMSSD, NN50 and pNN50 components. The high stress index during the time of application of the Stroop Test corroborates the values of the increased SNS index. The components of the frequency domain showed an increase in LF and LF/HF and maintenance of HF, while in the results of the Poincaré graph, the values of SD1 and SD2 reduced and the SD2/SD1 ratio increased. In the correlation analyses, it is possible to notice that the performance regarding the reaction time of the Stroop test is directly proportional to the components RMSSD, NN50, pNN50 and to the PNS index, while the stress index is inversely proportional. The other components did not show statistical significance. It is possible to verify that the Stroop Test was able to generate physiological changes with important responses in HRV, but further studies are needed on the stressful effect on athletes, as they are frequently subjected to both physical and mental stress, and that this frequency can lead to long-term cardiac overload.Item Ozonioterapia associada a um programa de exercício na dor e incapacidade de indivíduos com dor lombar crônica: ensaio clínico controlado e randomizado(Universidade Brasil, 2022) Silva, Rafael Basatos; Garcia, Lívia Assis; Tim, Carla RobertaChronic low back pain (CLBP) is one of the most common musculoskeletal disorders, prevalent worldwide and one of the main causes of disability and damage to quality of life, representing a significant economic burden. Ozone therapy (OT) has been suggested in clinical practice as an adjuvant therapy to physical exercise, however the evidence is limited for its recommendation. Thus, the aim of this study was to evaluate the effects of OT in combination with a physical exercise protocol on pain level in subjects with chronic low back pain. Forty-two volunteers were randomized into 2 groups: Control group (Ex): volunteers underwent a physical exercise protocol; Ozone Therapy Exercise Group (ExOT): volunteers underwent a resistance physical exercise protocol associated with OT. Interventions were performed twice a week for a period of 6 weeks, totaling 12 sessions. The exercise program consisted of exercises that strengthened, stretched, mobilized, coordinated and stabilized the abdominal, lumbar, pelvic and lower limb muscles. OT was applied at 5 points on the paravertebral muscles, bilaterally, totaling 10 points, through the intramuscular technique at a concentration of 20 g/ml and with a volume of 2 mL of ozone right after each proposed exercise session. For assessment and reassessment, the Numerical Pain Scale (END) was applied; disability index (Oswestry Disability Index); flexibility test (Third finger to floor test); trunk flexion/extension mobility test (Gonimetry); kinesiophobia (Kinesiophobia Cap Scale); emotional state (Anxiety Numerical Scale - ENA) and assessment of the perception of the global effect (Global Effect Perception Scale - EPEG). The results showed that both the Ex and the ExOT groups had a lower pain level, lower scores in disability tests, improved flexibility, lower scores in kinesiophobia when compared to the initial values. However, the lowest scores for the level of pain, disability and the highest scores for the level of perception of recovery were evidenced in the ExOT group. Thus, it can be suggested that OT associated with the physical exercise program was a more effective method in reducing pain and functional disability in the treatment of CLBP.Item Efeitos da indução de estresse mental na variabilidade da frequência cardíaca em atletas de Badminton(Universidade Brasil, 2021) Carvalho, Jane Maria Silva; Navarro, Ricardo ScarparoThe objective of the study was to analyze the effects of mental stress induction on heart rate variability in Badminton athletes.
