Physiological Responses in OSA Patients to Ramping Exercise After CPAP TreatmentShifflett, D. Edward Jr. 05 June 1998 (has links)
Continuous positive airway pressure (CPAP) is the primary therapy administered for those afflicted with obstructive sleep apnea (OSA). We examined the effects of CPAP therapy on physiological variables during a ramped exercise. The five male, OSA patients had mean values and standard deviations for RDI=60.7 +/- 19.1, BMI=29.9 +/- 2.9, and age=56 +/- 16.1 yr. Subjects were examined before and after 4 wk of CPAP therapy. After 4 wk of CPAP therapy, patient responses to exercise showed a 17.6%, (p<0.05) improvement in rating of perceived exertion (RPE) at identical power outputs (60% of the individual's apparent functional capacity). Statistical significance was not attained (p>0.05) upon analysis of the following parameters at 60% of the individuals maximum workload although there was a trend showing a decrease in these variables: heart rate (6% improvement), VO2 (11.7% improvement) systolic blood pressure (4% improvement), and rate pressure product (8.6% improvement). This data shows that the decrease in RPE during 60% of the individual's maximum predicted HR reserve corresponded with an increase in sleep quality (mean increase of 40%, 3.2 units) as measured by the Pittsburgh Sleep Quality Index before and after 4 wk of CPAP therapy. It was concluded that the improvement in exercise tolerance could be attributed to the subjective feelings of improved sleep quality after 4 wk of CPAP therapy. Key Words: Obstructive sleep apnea---CPAP--- exercise---physiological responses. / Master of Science

Apolipoprotein E ε4 allele modulates the immediate impact of acute exercise on prefrontal functionDe Marco, M., Clough, P.J., Dyer, C.E., Vince, R.V., Waby, Jennifer S., Midgley, A.W., Venneri, A. 14 September 2014 (has links)
Yes / The difference between Apolipoprotein E ε4 carriers and non-carriers in response to single exercise sessions was tested. Stroop and Posner tasks were administered to young untrained women immediately after walking sessions or moderately heavy exercise. Exercise had a significantly more profound impact on the Stroop effect than on the Posner effect, suggesting selective involvement of prefrontal function. A significant genotype-by-exercise interaction indicated differences in response to exercise between ε4 carriers and non-carriers. Carriers showed facilitation triggered by exercise. The transient executive down-regulation was construed as due to exercise-dependent hypofrontality. The facilitation observed in carriers was interpreted as better management of prefrontal metabolic resources, and explained within the antagonistic pleiotropy hypothesis framework. The findings have implications for the interpretation of differences between ε4 carriers and non-carriers in the benefits triggered by long-term exercise that might depend, at least partially, on mechanisms of metabolic response to physical activity. / Partially supported by a University of Hull Faculty of Science scholarship to MDM and by funding from MIUR and FP7 VPH-DARE to AV.

Physiological Responses in Initial Psychological InterviewsPerkinson, Robert R. 01 May 1974 (has links)
The purpose of this study was to determine the physiological responses of subjects to an initial psychological interview, and to study the effect of physical proximity and touch on these responses. Heart rate and total skin conductance variability were the responses monitored. To assess the subjects' like or dislike of the psychologist interviewer, a measure of interpersonal attraction, the Interpersonal Judgment Scale, was employed. The California Psychological Inventory was utilized to investigate possible personality correlates with the physiological responses.
Sixty females, between the ages of 18 and 28, responded to the California Psychological Inventory and were then connected to the physiological monitoring devices. The subjects' physiological responses were recorded for a 10-minute period in an empty office and then they randomly received one of the following treatments: In treatment I the psychologist entered the counseling office, introduced himself, and sat one foot from the subject while orally administering the Rotter Incomplete Sentences Blank--Adult Form. When the psychologist reached item 15 he stated, "Very good, now let's go on to page 2." After the test, the psychologist said, "That's all for today, thank you for your help. If you will wait here, the experimenter will be right in." The psychologist then left the office, and the subject responded to the Interpersonal Judgment Scale. Treatment II was identical to treatment I, except the subject was touched three times during the interview, once on the shoulder and twice on the arm. In treatment III the psychologist entered the office, sat behind a desk and followed the procedure outlined in treatment I.
The results indicated that a subject's reaction to an initial psychological interview is a mild to moderate defensive response manifested by an increase in physiological stress levels. Total skin conductance variability increased significantly during the period when the psychologist was in the office. Heart rate increased in 54 out of 60 cases, but did not increase sufficiently enough in magnitude to justify significance.
There were no significant differences between the three treatment groups on heart rate, skin conductance, or interpersonal attraction, and there were no personality correlates which were great enough to be of practical value.
The data collected in the experiment supported the conclusion that a subject's reaction to an initial psychological interview is a mild to moderate stress response manifested by increments in physiological stress levels. Touch and physical proximity do not appear to alter the stress response or the subject's like--dislike attitude toward the psychologist.

Previous issue date: 2015-12-08 / A large number of heifers and cows are used in Brazil for the production of meat, mainly due to the disposal of these animals on farms at the time of the herd replacement. The aim of this study was to evaluate the influence of a synthetic-progesterone ear implant in weight, meat quality, physiological responses, and behavior of Nellore heifers raised in an intensive system. Twenty-eight Nellore heifers with an average initial weight of 240.89 kg were used in the experiment. All animals received the same feeding management, in an intensive raising system, with mineral salt and water available ad libitum. Heifers were distributed in a randomized complete design with two treatments (with and without a progesterone ear implant) and seven replicates, in 14 stalls. The parameters relative to carcass and meat quantitative and qualitative characteristics, represented by carcass weight and carcass dressing, conformation, marbling, color, meat texture, carcass measurements, longissimus dorsi area, and fat thickness were not affected by the progesterone hormone, provided by the ear implant. In the evaluation of the feeding, rumination, rest, sleeping, social, and body-care behaviors, no significant differences were observed. For the abnormal behavior, however, in which sodomy predominated, a significant difference was observed between the groups with and without the implant (p<0,05), whose frequencies were 1.3 and 2.3, respectively. For the physiological indicators rectal temperature, surface temperature, and respiratory frequency, only the frequency showed a significant difference between the treatments, with mean values of 35 and 32 movements per minute, respectively, for the heifers with and without the implant. Based on the responses obtained in this experiment, the progesterone ear implant does not influence the performance, meat quality, physiological responses, or the normal behavior of animals. / Um grande número de novilhas e vacas são utilizadas no Brasil para a produção de carne, principalmente em decorrência do descarte desses animais nas propriedades rurais, no momento da substituição do rebanho. Objetivou-se avaliar a influência do implante auricular de progesterona sintética, no peso, qualidade de carne, respostas fisiológicas e comportamento de novilhas Nelore criados em sistema intensivo. Foram utilizadas 28 novilhas Nelore com peso inicial médio de 240,89 kg. Todos os animais receberam o mesmo manejo alimentar, em sistema intensivo de criação, com sal mineral e água ad libitum. Foram distribuídas em delineamento inteiramente casualizado, com dois tratamentos (com e sem implante auricular de progesterona) e sete repetições, em 14 baias. Os parâmetros referentes às características quantitativas e qualitativas da carcaça e da carne, representados pelo peso e rendimento da carcaça, conformação, marmoreio, coloração, textura da carne, medidas métricas da carcaça, área do músculo Longissimus dorsi e espessura de gordura subcutânea, não foram afetados pelo hormônio progesterona, disponibilizado por meio do implante auricular. Na avaliação dos comportamentos de alimentação, ruminação, descanso e sono, social e cuidados corporais, não foram observados diferenças significativas. Já para o comportamento anormal, com maior predominância de sodomia, houve diferença significativa (p<0,05) para os grupos com e sem implante, com frequências de 1,3 e 2,3, respectivamente. Para os indicadores fisiológicos, temperatura retal, temperatura de superfície e frequência respiratória, apenas a frequência apresentou diferença significativa entre os tratamentos, com valores médios de 35 e 32 movimentos por minuto, respectivamente, para novilhas com e sem implante. Considerando as respostas obtidas com o experimento, o implante auricular de progesterona não influencia o desempenho, a qualidade da carne, as respostas fisiológicas e o comportamento normal dos animais.
