Examination Stress

O b j e c t i v e : 1: To examine the effects of examination stress in young adult male and female medical students on cardiovascularsystem and thyroid gland (i.e. thyroid hormones; T3,T4).2:To find out whether the responses are sex dependent or not. S e t t i n g : Departmentof Biochemistry NMC Multan (1997-1998). Patients a n d m e t h o d : Examination stress was studied in 28 young female and 21 young malevolunteer medical students, 0.5 hour before Biochemistry examination (stress condition), at 10-12 a.m. and about six weeks after examination(control condition) at the same time in the year 1997. Estimation of Thyroxine (T4) and Triiodothyronine (T3) and T3 /T4 was done in patientsand control subjects. R e s u l t s : There were no differences in body mass index of male and female groups in control and stress group.Subsequent analysis between two sexes showed that males subjects had significantly higher systolic (124.7±40.1 mmHg) and diastolic bloodpressure (76.56±2.48 mmHg). Heart rate (84.6±2.63) increases in stress condition, in both sexes, but in males the increasing of heart rate ismore than in females. Whereas females had higher respiratory frequency in stress condition, as compared to males. The levels of T3 in femalestress group were higher than male stress group but statistically not significant. The mean values of T4 were highly significant in female stressgroup than in male stress group. C o n c l u s i o n s : Stress responses to examination are different between two sexes. The differences in responsesto examination stress between male and female showed a greater increase in systolic and diastolic blood pressure, heart rate, respiratory rateand also thyroid hormones in response to stress. It is suggested that as the examination is a stressful condition and different effects of stresson male and female medical students should be considered. The clinical presentation is palpitations, tremors, nervousness, apathy, fatigue,thirst, and emotional un-stability is due to the increase of thyroid hormones. Students are guided to remain relaxed, as neurotransmitters andhormones are released which may effect the overall performance of the students. Further study may be down to find out the effects of stresson other systems of the body which may be helpful in future to avoid the poor mental health status during the examination.

Central Hemodynamic

Background: One of the main negative factors of the educational environment is the increased stress impact on the cardiovascular system of students preparing for examinations. The cumulative effect of a long-term, systematic exposure to stressors may be accompanied by impaired mental and somatic health of students. The extent of response to stress is individual; it is usually determined by cardiovascular health and a complex of psychophysiological characteristics of the body. Objective: To study the main parameters of central hemodynamics in medical students depending on the body mass index and adaptive potential in the pre-examination study period Materials and methods: In spring–summer 2019, 170 medical students (young men and women aged 20.4 ± 0.3 years) with different adaptive potential of the circulatory system were surveyed during a pre-exam study period to establish their anthropometric indicators, blood pressure and heart rate and to further estimate the body mass index and the main central hemodynamics parameters. Results: The average heart rate of students during the pre-exam study period was 85.4 ± 12.21 beats per minute. The level of metabolic and energy processes in the myocardium was characterized as moderate with a tendency to insufficient functional capacity of the cardiovascular system (CI = 90.4 ± 1.22). Significant differences were revealed in a number of parameters un-der study depending on gender, body mass index (F = 3.99; p = 0.00890) and the adaptive potential of the circulatory system (F = 23.08; p = 0.00000). Conclusions: In the pre-examination study period, both the heart rate and the Kerdo index among the students were elevated, which indicates the predominance of sympathetic autonomic stress. The students with tense adaptation mechanisms demonstrated higher values of certain hemodynamic parameters. The pulse pressure and the Robinson index were higher in overweight students compared to their peers with a normal body mass index. None of the students with class 1 obesity had a satisfactory level of adaptation of the circulatory system. The analysis of central hemodynamic parameters enables the assessment of tolerance of the cardiovascular system of students to the burden of learning.

Objectives: To analyze the effects of Examination stress on heart rate, blood pressure and white blood cells among medical college students. Study Design: Observational study. Setting: Department of Pathology, Indus Medical College, Tando Muhammad Khan Sindh. Period: September 2018 to April 2019. Material & Methods: 200 medical students were selected according to inclusion and exclusion criteria. Heart rate was measured manually. Systemic Blood pressure (BP) was recorded by Sphygmomanometer. Mean arterial BP was calculated as diastolic BP+1/3 of pulse pressure. Blood slides were stained with Leishman`s stain and white blood cells were counted using microscope.  Data was analyzed by using Statistical Package for Social Sciences (ver 22.0) for windows Microsoft. Results: Age of study subjects was noted as 20.23±1.23 years.  Body weight and Body mass index (BMI) were noted as 64.93±7.53 Kg (P=0.0001) and 27.5±5.3 (P=0.67). Of total 200, 109 (54.5%) were male and 91 (45.5%) were female (P=0.0001). Heart rate, Systolic, Diastolic and Mean arterial BP differed significantly before and after examination stress (P<0.05). White blood cells before examination were found as 7310.43±708.5 x103/µL compared to 8202.39±677.26 during examination stress (P=0.0001). Conclusion: Examination stress perturbs the physiological homeostasis as changes in heart rate, blood pressure and White blood cells are noted among medical students. Psychological and physical strategies for coping the stress should be considered for the young medical students.

Traditionally, horse riding has been restricted to men but today equestrian sports are dominated by women. We hypothesised that men and women differ with regard to riding and the response they evoke in their horse. Cortisol and heart rate variability (HRV) were studied in male (n=8) and female riders (n=8) and in horses (n=8) ridden by men and women over a jumping course. Saliva for cortisol analysis was collected, cardiac beat to beat (RR) intervals were recorded and heart rate and HRV variables SDRR (standard deviation of RR interval) and RMSSD (root mean square of successive RR differences) calculated. In another experiment, saddle pressure was compared between male and female riders (n=5 each). Cortisol did not differ between male and female riders and increased in horses (P<0.001) irrespective of the sex of the rider. Heart rate in riders increased from walk to jumping (P<0.001) while HRV decreased (P<0.001) to the same extent in men and women. In horses, heart rate increased (P<0.001) and SDRR and RMSSD decreased during walk and remained low at trot and canter (P<0.001) irrespective of the riders’ sex. In trot (P<0.05) and canter (P<0.01) saddle pressure was slightly lower in female versus male riders. This is due to weight differences and not to a different seat. In conclusion, no fundamental differences existed in the physical effort, stress response and seat between male and female riders and in the response of horses to men and women.

OBJECTIVES To determine the effects of exercises by using treadmill leading to cardiac diseases due to HTN response of exercise among ectomorph male and female. STUDY DESIGN An experimental study design was used. STUDY SETTINGS & PARTICIPANTS 30 students that were studying in a reputed institution with BMI of 18.5 (both male and female) were the part of this study. INTERVENTIONS Heart rate and blood pressures were measured through Heart Rate Monitor, Mercury Sphygmomanometer, Weighing Scale Treadmill, and Stadiometer was used to collect data. The data was analyzed through SPSS.16, through paired sample t test. RESULTS No statistically significant differences were obtained in post exercise B.P among ectomorph men and women where as significant difference between pre-exercise and post-exercise heart rates on ectomorph were obtained. CONCLUSIONS B.P and H.R are two significant indicators in our body that give signal about many cardiac diseases silently existing in our body. Our study concluded that the body responses to exercise are similar in both ectomorphs male and female; therefore ectomorphs have equal risk factor for cardiac diseases.

Energy balance of 10 male and 8 female triathletes participating in an Ironman event (3.8-km swim, 180-km cycle, 42.2-km run) was investigated. Energy intake (EI) was monitored at 7 designated points by dietary recall of food and fluid consumption. Energy expenditure (EE) during cycling and running was calculated using heart rate-V̇O2 regression equations and during swimming by the multiple regression equation: Y = 3.65v + 0.02 W − 2.545 where Y is V̇O2 in L · min−1, v is the velocity in m · s−1, Wis the body weight in kilograms. Total EE (10.036 ± 931 and 8570 ± 1014 kcal) was significantly greater than total El (3940 ± 868 and 3115 ± 914kcal, p < .001) formales and females, respectively, although energy balance was not different between genders. Finishing time was inversely related to carbohydrate (CHO) intake (g · kg−1 · h−1) during the marathonrun formales (r=−.75, p < .05), and not females, suggesting that increasing CHO ingestion during the run may have been a useful strategy for improving Ironman performance in male triathletes.

Introduction. An osteopathic examination determines the rate, the amplitude and the strength of the main rhythms (cardiac, respiratory and cranial). However, there are relatively few studies in the available literature dedicated to the influence of osteopathic correction (OC) on the characteristics of these rhythms.Goal of research — to study the influence of OC on the rate characteristics of various rhythms of the human body.Materials and methods. 88 adult osteopathic patients aged from 18 to 81 years were examined, among them 30 men and 58 women. All patients received general osteopathic examination. The rate of the cranial rhythm (RCR), respiratory rate (RR) heart rate (HR), the mobility of the nervous processes (MNP) and the connective tissue mobility (CTM) were assessed before and after the OC session.Results. Since age varied greatly in the examined group, a correlation analysis of age-related changes of the assessed rhythms was carried out. Only the CTM correlated with age (r=–0,28; p<0,05) in a statistically significant way. The rank dispersion analysis of Kruskal–Wallis also showed statistically significant difference in this indicator in different age groups (p=0,043). With the increase of years, the CTM decreases gradually. After the OC, the CTM, increased in a statistically significant way (p<0,0001). The RCR varied from 5 to 12 cycles/min in the examined group, which corresponded to the norm. After the OC, the RCR has increased in a statistically significant way (p<0,0001), the MNP has also increased (p<0,0001). The initial heart rate in the subjects varied from 56 to 94 beats/min, and in 15 % it exceeded the norm. After the OC the heart rate corresponded to the norm in all patients. The heart rate and the respiratory rate significantly decreased after the OC (р<0,0001).Conclusion. The described biorhythm changes after the OC session may be indicative of the improvement of the nervous regulation, of the normalization of the autonomic balance, of the improvement of the biomechanical properties of body tissues and of the increase of their mobility. The assessed parameters can be measured quickly without any additional equipment and can be used in order to study the results of the OC.

AbstractBackground: The purpose of the following research was to find out the influence of imaginary training based on intention implementation on throw effectiveness of young basketball players, both male and female in stressogenic situations. Individual differences (action vs state orientation) between players were also measured in this research.Material/Methods: 76 players (32 females and 44 males) in the cadet category (15-16 years old) from basketball clubs of Gdansk, Gdynia and Sopot took part in this research. In the first stage all players did a throw efficiency test ERPE 05 under two conditions, and their heart rate was measured. Then players were randomly assigned to one of two groups. The first one did imaginary training based on the influence of intention implementation for 10 days, while the other did not. After 10 days ERPE 05 test under two conditions was run again.Results: Test results showed that intention implementation does not influence effectiveness improvement in stressogenic conditions as far as state-oriented players are concerned, but it does lower the physiological cost of physical effort in form of a decreased heart rate.Conclusions: This research proves that visualization training based on implementation instructions does influence young players’ physiology and significantly lowers their heart rate under stressogenic conditions. However useful, visualization techniques used in this research still need other tests and should be applied for a longer period of time to acutely show how they affect young players’ mental preparation

Disturbance of the thyroid function is often detected in patients with different profiles. A special feature of patients with chronic kidney  disease is the higher incidence of various thyroid function  disturbances, especially hypothyroidism. It is known that in patients  with chronic kidney disease (CKD) iodine excretion from the body is  violated, since normally 90% of iodine is excreted in urine.  Accumulation of high concentrations of inorganic iodine leads to the  formation of the Wolf-Chaikoff effect: suppression of iodine  organization in the thyroid gland and disruption of the thyroid  hormones synthesis. Peripheral metabolism of thyroid hormones is  also disturbed, namely, deiodinase type I activity is suppressed and  peripheral conversion of T4 into T3 is inhibited (so-called low T3  syndrome). Therefore, patients with CKD are often diagnosed with  hypothyroidism, and the origin of hypothyroidism is not always  associated with the outcome of autoimmune thyroiditis. The article  presents an overview of a large number of population studies of  thyroid gland dysfunction in patients with CKD, as well as  experimental data specifying the pathogenetic mechanisms of  thyroid dysfunction in patients with CKD. Therapeutic tactics are still  not regulated. However, in a number of studies, replacement therapy with thyroid hormones in patients with CKD had some advantages.

The assessment and dynamic control over students’ status is a very important task. It allows timely detection of prenosological status prior to pathology and health maintenance in students. The objective of the paper is to assess the adaptive abilities of the body, to analyze changes in heart rate variability indicators in students with various types of autonomic regulation, to identify prenosological status and precursory pathological symptoms. Materials and Methods. The study enrolled 302 students from India, aged 21.54±1.43. Programming complex «Psychophysiologist» was used to register the main HRV parameters within 5 minutes. Health status was evaluated according to the index of functional changes and the scale of functional states. Results. N.I. Shlyk (2009) distinguished two groups of students with different types of autonomic regulation: type 1 (53 %) with moderate and type 2 (5 %) with marked characteristics of central regulation profile, type 3 (35 %) with moderate and type 4 (7 %) with marked characteristics of autonomous regulation profile. Main parameters of HRV and adaptation potential were defined for each student.All the parameters characterized functional and health status. Conclusions. It was shown that 82 % of trial subjects (type 1), 53 % (type 2), 94 % (type 3) and 95 % (type 4) demonstrated satisfactory adaptation and their physiological processes were at an optimal level. 18 % of students (type 1) demonstrated reduced adaptive abilities of the body. Moreover, they were under moderate stress. 47 % of subjects (type 2) were also under a significant stress, which was proven by excessively high SI, low SDNN and TP, and an increased index of functional changes. 5 % of students (type 4) revealed dysfunctional characteristics in the heart rhythm, peculiar to pathology. Keywords: foreign students, heart rate variability, types of autonomic regulation, adaptation potential, functional status.
