Adaptation To Training

Background A factor favoring the swimming performance increase is the adaptation and readaptation of body energetic and functional systems to the physical and mental stress stimuli in training and competitions. The efficiency of monitoring the young swimmers’ training is based on a precise determination of the changes in the specific adaptations. The evaluation and control of the biochemical, mental and motor changes ensure the knowledge of the particularities of body adaptation in different training stages. Methods Six young swimmers aged 12–16 years specialized in 100 m event participated in this study, conducted in four stages (E1–general, E2–specific, E3–pre-competitive and E4–competitive). The distress occurrence during adaptation to training and competition stimuli was studied in 3 levels: mental (Cohen & Williamson Test (CWT), Cohen Perceived Stress Test (CPST), Competition Anxiety Test (SCAT), Crăciun Test (CT)), motor (workouts monitoring, planning of means on training areas, anaerobic threshold assessment and average training speed calculation) and biochemical (blood lactate (La) and blood glucose (Glu) before and after effort—5 and 15 minutes; level of metabolic biochemical parameters, lymphocytes and blood glucose, and also hormonal parameters—norepinephrine, prolactin and cortisol—before and after competition effort). Results Quantity results of the mental, motor and biochemical tests were analyzed in groups; the quality results for each subject in dynamics were analyzed by comparison and correlation. Psychological tests showed increases in athletes’ mental behavior by 34% at CWT (p < 0.05), by 37.5% at CPST (p < 0.05), average stress level at SCAT and 70% stress in self-confidence at CT (p < 0.01). Biochemical tests revealed an ascending dynamics of La accumulated after specific effort, with peaks in E2 period (p < 0.05) and decreases in E3 compared to E2 (p < 0.05), revealing the adaptation to specific effort and the increase in anaerobic capacity. The Glu values decrease in pre-effort and increase in minute 5 and 15 post-effort (p < 0.05) in E2 and decrease in pre- and post- effort in E3 (p < 0.05), showing the effort impact on body and ability to recover after effort. Athletes’ individual metabolic results were 50% above maximum values, mainly post-effort (42%); hormonal results were 17% over maximum values, mainly post-effort (14%). Spearman’s correlative analysis of the induced-stress stimuli in workouts revealed 6.06% significant correlations at p < 0.05 and 9.1% strong connections in competitions: 4.67% significant correlations at p < 0.05 and 6.4% strong connections. Conclusion The research demonstrated that the mental and biochemical tests results correlation with the specific motor tests facilitated the correct individualization of effort orientation in training and recovery and contributed to the knowledge of the particularities of young swimmers’ body adaptation to training and competition effort.

Sympathetic hyperactivity may be involved in primary hypertension. The purpose of this study was to evaluate both sympathetic and vagal activity responses in patients receiving amlodipine as antihypertensive agent. Patients and Methods. This prospective study included a group of primary hypertensive patients (N=32, mean age 54.6±7.6 years). The cardiovascular autonomic tests performed in this group, before and after 3 months of daily oral administration of amlodipine, included deep breathing, hand-grip, and mental stress tests. Statistical analysis was done using the Student’s t-test. Results. Cardiovascular autonomic reflexes responses before and after 3 months of amlodipine oral administration were as follows: the mental stress test stimulation method produced a central alpha adrenergic response of 23.9±8.7% versus 11.2±2.0% (P<0.05), a central beta sympathetic response of 16.7±9.2% versus 10.4±1.3% (P<0.05), a blood pressure increase in response to hand grip test of 20.5±7.3% versus 10.7±2.4% (P<0.05), vagal response to deep breathing test was 21.2±6.5% versus 30.8±2.9%, (P<0.05). Conclusion. The results attest that amlodipine may have an anti-sympathetic effect.

The prevention of Diabetic Mellitus (DM) and its complications is the main aim of this study, in addition to the training of lotion foot care application and the development of small scale industry. The research team delivered knowledge in the form of training on Diabetic Mellitus, healthy food, treatment and prevention of complications, and small-scale production of cosmetic products. The aim of this study was to determine the correlation between training on diabetic and lotion foot care application as preventive measures against diabetic complications on the patient's blood glucose levels in the community of residents in Banyuurip Jaya, Surabaya. It was expected from this training that the knowledge of the residents increases and people living with diabetic undergo lifestyle changes and therefore blood sugar levels can be controlled. The parameters measured in this research were blood glucose levels, the anti diabetic drug types consumed, and compliance on diabetics. This study used the data taken from 60 patients with DM over a period of one month. Questionnaires and log books was used to retrieve data and changes in blood glucose levels in diabetic patients. The results showed the demographic data of patients with type 2 diabetic of 85% female and 15% male, with the range of patients aged of 61-70 years of 46.67% and had history of diabetic (90%). The history of drugs consumed by respondents was anti diabetic drugs such as metformin (40%), glimepiride (33.37%) and insulin (6.67%). In addition, the increased knowledge of DM patients after being given the training compared to before training was shown in several questions in the questionnaire. A statistical analysis using t-test analyzed a correlation between training provided in order to enhance understanding of the patient, as well as correlation with blood glucose levels. A paired T-test showed that there was a relationship between the knowledge of trainees before and after training (p less than 0.05). An interesting result was that there was no relationship between blood glucose levels before and after training provided (p> 0.05).

(1) Background: Cardiovascular diseases, in particular, myocardial infarction (MI), are the main threats to human health in modern times. Cardiac rehabilitation (CR), and especially increased physical activity, significantly prevent the consequences of MI. The aim of this study was to assess physical performance in patients after MI before and after CR. (2) Methods: 126 patients after MI were examined. They were admitted to the cardiac rehabilitation ward twice: in the 3rd month after MI, and then in the 6th month after the last rehabilitation session. CR lasted 20 treatment days (4 weeks with 5 treatment days and 2 days’ break). The exercise stress test on the treadmill and a 6-minute walk test (6MWT) were used to assess physical performance. Patients were assigned to an appropriate rehabilitation model due to their health condition. (3) Results: In the studied group, the exercise stress test time and the metabolic equivalent of task (MET), the maximal oxygen consumption (VO2max), and 6MWT score increased significantly (p = 0.0001) at two time-points of observation. (4) Conclusion: CR significantly improves physical performance in patients after MI.

AbstractObjectivesOur aim was to evaluate the effect of standard surgical and N-95 respiratory mask use on maternal oxygen saturation, vital signs and result on non-stress tests in term pregnancies.MethodsIt is a prospective observational study. The study included healthy, not in labor, singleton pregnant women of 370/7–410/7 weeks who were applied to our hospital for routine obstetric control examination between March 1, 2020, and August 31, 2020. Patients were randomised by coin toss method. Oxygen saturation, systolic, and diastolic arterial blood pressure, pulse, respiratory rate, and temperature of pregnant women using surgical masks and respiratory masks were measured before and after the non-stress test. The tolerance of the masks was also evaluated. Student’s t-test was used for variables showing parametric distribution and the Mann Whitney U-test was used for non-parametric tests. The categorical variables between the groups was analyzed by using the Chi square test or Fisher Exact test. The statistical significance level was taken as p<0.05 in all tests.ResultsA total of 297 pregnant women using masks were included in the study. The effect of mask type on oxygen saturation before and after the non-stress test was found to be significant (97.1±1.8 corresponds to 95.3±2.6 for the surgical mask, p=0.0001; 97.8±1.7 corresponds to 93.7±2.0 for the respiratory mask, p=0.0001). Mask tolerance of patients using respiratory masks was significantly higher than those using surgical masks (mean 8, 1–10, p=0.0001).ConclusionsSurgical mask and respiratory mask usage decreased significantly in oxygen saturation in term pregnancies.

Abstract Objective To evaluate factors associated with anxiety and the effect of simulation-based training (SBT) on student anxiety, self-confidence and learning satisfaction in relation to pelvic and breast examination. Methods A longitudinal study was conducted with 4th year medical students at the Universidade José do Rosário Vellano. A 12-item, self-report questionnaire on student anxiety at performing gynecological examinations was applied before and after SBT, with answers being given on a Likert-type scale. After training, the self-confidence levels and satisfaction of the students related to the learning process were also evaluated. Results Eighty students with a mean age of 24.1 ± 4.2 years were included in the study. Of these, 62.5% were women. Pre-SBT evaluation showed that students were more anxious at performing a pelvic examination than a breast examination (2.4 ± 1.0 versus 1.7 ± 0.8, respectively; p < 0.001). The primary reason for anxiety regarding both pelvic and breast examination was fear of hurting the patient. SBT significantly reduced student anxiety (2.0 ± 0.8 versus 1.5 ± 0.5, respectively; p < 0.001). The satisfaction and self-confidence of the students were found to be high (6.8 ± 0.3 and 6.0 ± 0.9, respectively), with no difference between genders. Conclusion The use of SBT in teaching students to perform pelvic and breast examinations resulted in reduced anxiety and increased self-confidence in a group of medical students of both genders, with high levels of satisfaction in relation to the training.

AIMS: To verify the effectiveness of the simulation in the self-confidence of nursing students for extra-hospital cardiopulmonary resuscitation. METHODS: A quasi-experimental, before and after, single-group study, was performed with nursing undergraduate students. The sample was recruited among university students who were in the second or third year of graduation and accepted to participate in the research. The intervention protocol consisted of individual participation in a emergency simulated clinical scenario. The simulated scenario adopted consisted of cardiopulmonary resuscitation in extra-hospital cardiorespiratory arrest, using the Mini Anne Plus® low fidelity manikin. In addition to the sociodemographic variables, students' self-confidence for emergency action was analyzed, evaluated by the Self-Confidence Scale, before and after each simulation. Marginal and homogeneous Wilcoxon homogeneity tests were applied, and the accepted significance level was 5%.RESULTS: Thirteen two undergraduate students in nursing between the ages of 18 and 38 participated in the study. Statistically significant differences (p < 0.001) were observed in the answers of all the questions of the Self-confidence Scale when compared before and after the simulation. There was also a statistically significant increase (p < 0.001) in cardiological, respiratory and neurological scores after simulation.CONCLUSIONS: The simulation proved to be an effective educational strategy in increasing the self-confidence of nursing students to perform extra-hospital cardiopulmonary resuscitation.
