The purpose of the study was to determine if perceived severity of the consequences of physical inactivity is an important component for exercise motivation in college students. The participants of the study were 581 college students who had enrolled in HSC 160, Fundamentals of Human Health, at Ball State University during the spring semester of 2001. Using a cross-sectional data collection process, participants completed a survey instrument consisting of the stages of change for exercise scale, the perceived severity of the consequences of physical inactivity scale, and demographic questions.The data were analyzed using both univariate and bivariate analyses. Specific descriptive and inferential statistic analyses were used to: 1) determine the degree of association between the participants' perceived severity and their identified stages of change for exercise, 2) examine the relationship between the stages of change for exercise and the participants' demographic characteristics, and 3) determine the difference between perceived severity of consequences of physical inactivity and the Participants' demographic characteristics. / Department of Physiology and Health Science

This thesis focuses on the physical and mental hygiene habits of younger school children. The theoretical part of the thesis deals with physical activity, effects of hypokinesia and mental hygiene specificity of this age group in the context of physical and psychosocial. The research evaluates the results of data from pedometers and the results of the survey, to which were used questionnaires "Time Picture of the Day"(Mužík, Bártová, 2010) and a questionnaire of daily regimen (Řehulka, 1987). This is a quantitative research. There were processed 104 questionnaires that were filled by children from 4th and 5th grades at selected elementary schools in Strakonice. The results show the differences in the amount of physical activity on school and weekend days, total amount of physical activity is satisfactory and further show the connection between a length of sleep and fatigability during the day.

The thesis is focused on leisure-time activities structure of high school students, with an emphasis on physical activity. In the theoretical part are elaborated chapters concerning the definition of leisure-time, physical activity and adolescence, describes negative impacts of hypokinesia and presents the basic information about procject COMPASS. The researsch study is focused on physical activities of adolescents in their leisure-time context. The data found from respondents (n=425) was registred via stadardized sociological questionnaire COMPASS. The aim of the study was find out gender and age differences in the structure of leisure-time physical activities of high school students. The results shows, that almost 85% of adolescents regulary participate in at least one sport or another type of physical activity in leisure time. Gender has bigger influence on differences in the leisure-time structure than the age. This study shows that physical activities are substantial part of leisure-time of adolescents.

Title: Consequences of forced hypokinesia on human movement aparatus. Objectives: The aim of this study was to find out the influence of forced hypokinesia after total hip replacement on the excitability of α motoneurons. I deal with the changes of H-reflex and M-wave latencies and the changes of the recruitment curves. The results of the operated and non-operated (kontrol) lower limb were compared. Methods: Five volunteers 3 - 4 weeks after total hip replacement participated in this study. The age was 62,4 (± 3,01). The H-reflex was elicited by stimulation of tibial nerve in a poplitel fossa. The H-reflex and M-wave latencies and its recruitment curves were obtained. After that the values of the operated lower limb were compared with the non-operated one (control). The results were evaluated as case studies. The EMG device Grass Telefactor was used to detect the electrical potential of soleus muscle. The rectangular pulses of 0,5 ms duration were used for stimulation tibial nerve by Grass 88 Stimulator. Then the data were transduced by CED Power 1401 device. Results: We found out that the H-reflexes of both lower limbs were not elicited in the case study no. 2 and the H-reflex of a control lower limb was not elicited in case study no. 1. The stimulus intensities for eliciting H-reflex and M-wave...

The topics of this diploma thesis are issues of a sedentary lifestyle and the influence of compensatory exercises as an instrument to compensate the muscle imbalances associated with it. In the theoretical part of my thesis, I focused on explaining and defining the basic problems of this topic and then on several already published international studies dealing with this issue for a long time. I have chosen three studies that reflect the problem on the human body and show significant problems connected with a sedentary lifestyle. For my own research I created compensation exercises for my selected reference group, that is the good specimen due to its sedentary occupation and the age between 40-51, based on the published international studies. For my research I have used the method of experiment in which I have used the testing, examination and evaluation techniques of the motor system. The plan of compensation exercises I created based on the imbalances I have studied and problems associated with a sedentary lifestyle. My research was also focused on the positive effects of physical activity in this group due to their workload and the causal link between a sedentary lifestyle and health of the respondents. The main objective of my thesis is to demonstrate the impact of this plan of compensation...

INTRODUÇÃO: Os efeitos da levodopa (LD) e da estimulação cerebral profunda (ECP) de núcleo subtalâmico (STN) sobre o equilíbrio e sintomas axiais são até o momento controversos. OBJETIVOS: Avaliar quantitativamente os efeitos da ECP de STN e da LD sobre o equilíbrio estático em pacientes com DP operados, em comparação com a LD em pacientes não operados. MÉTODOS: Trinta e um pacientes submetidos a ECP de STN entre 3 meses e 1 ano e meio antes da avaliação e 26 controles portadores de DP não operados, estágios Hoehn e Yahr 2 a 4 foram avaliados usando UPDRS para avaliação clínica e plataforma de força para avaliar oscilações posturais. O primeiro grupo foi avaliado com ECP e sem medicação, com ECP e com medicação e sem ECP e sem medicação. O segundo grupo foi avaliado com e sem medicação. Cada paciente foi avaliado com os olhos abertos e fechados. O deslocamento do centro de pressão anteroposterior, laterolateral, a área, velocidade e deslocamento total linear foram medidos pela plataforma de força. Os dados paramétricos foram comparados usando o teste t de Student e os dados não-paramétricos foram comparados pelo teste de Kruskal-Wallis. A avaliação clínica consistiu na parte 3 da escala UPDRS e na escala Hoehn e Yahr. Nível de significância estatística considerada foi p=0,05. RESULTADOS: Os pacientes não operados oscilaram mais quando sob efeito da levodopa do que sem medicação. No grupo operado, a maior oscilação é no grupo com ECP desligada e sem medicação. Tende a reduzir sob efeito da ECP apresenta redução significativa sob efeito simultâneo de ECP e levodopa. CONCLUSÃO: A associação da ECP de NST com medicação tem impacto positivo sobre o controle postural. O efeito da ECP de NST reverte o efeito negativo da levodopa sobre as oscilações observadas em pacientes não operados / INTRODUCTION: The effects of bilateral subthalamic (STN) DBS and medication on balance and on axial symptoms in PD have been so far inconsistent. OBJECTIVE: To assess quantitatively the effects of DBS on static balance in PD. METHODS: Thirty-one patients submitted to STN DBS over 3 months before and 26 non-operated controls with PD on Hoehn & Yahr stage \"on\" 2 to 4 were evaluated using UPDRS and a force plate to measure sway. The first group was evaluated on-DBS/off-medication, on-DBS/on-medication and off-DBS/off-medication. The second group was evaluated on and off medication. Each group was assessed with eyes open and then closed. Antero-posterior, laterolateral postural displacements of the center of pressure (COP), as well as 95% sway area, path length and speed of oscillation were analyzed and compared using t-Student test for parametrical data and Kruskal-Wallis test for non-parametrical data. Level of significance was set to p < 0.05. Clinical assessment consisted of UPDRS part 3 and Hoehn & Yahr scores for each of the conditions. RESULTS: Control patients tended to oscillate more in the on medication condition than off medication. DBS patients tended to oscillate more in the off-DBS/off medication condition, with a tendency to decrease the sway when on DBS/off medication with additional decrease when on DBS/on medication. CONCLUSION: Association of bilateral STN DBS and medication positively influences postural control in PD and surgery reverses the tendency of medication to increase body sway in non-operated patients

Therefore, the aim of this research was to evaluate by clinical and morfometric analysis the effects of laser therapy on neural and muscle repair after crushing of sciatic nerve and hind limb unloading. 48 Wistar male rats machos, with 60 days old, were divided in three groups with 16 animals each, and they were performed as one control group (GA) and two irradiated groups (GB with 4 J/cm² dose; GC with 6 J/cm² dose). After the sciatic nerve was crushed animals were maintained under hind limb suspension and received laser (GaAlAs) irradiation three times per week, during 14 or 28 days. The sciatic functional index (SFI) were measured before surgery, at 14 and 28 days, recovery was observed in all groups especially to GA at 28 days. Morfometric analysis of the nerve showed that the nerve recovery was better to the treated groups, specially at 14 days. The muscle morfometric analysis weren&#8217;t effected by laser therapy. Taken together the results allowed to conclude that laser therapy promotes morphological recover of the nerve, specially until 14 days. Yet laser isn&#8217;t able to influence the muscle recovery and function. / A irradiação com o laser é muito empregada para tratar uma variedade de condições patológicas do sistema músculo-esquelético, inclusive dos nervos periféricos. O objetivo desse trabalho foi avaliar por análises clínicas e morfométricas, a reparação neural e muscular após a compressão do nervo ciático de ratos submetidos à imobilização por suspensão e tratados ou não com diferentes doses de laser terapêutico. Foram utilizados 48 ratos machos, com idade de 60 dias, da raça Wistar, distribuídos em três grupos de 16 animais, sendo um utilizado como controle (GA) e outros dois que receberam diferentes doses do laser (GB com dose de 4 J/cm² e GC com dose de 6 J/cm²). Após a compressão do nervo ciático os animais foram submetidos à hipocinesia dos membros pélvicos e ao tratamento com Laser de GaAlAs três vezes por semana, durante 14 ou 28 dias. O índice funcional do ciático (IFC) foi avaliado nos períodos pré-operatório, aos 14 e aos 28 dias apresentando melhora para ambos os grupos, porém com destaque para o GA aos 28 dias. Os resultados da morfometria demonstraram que a recuperação do nervo foi melhor para os grupos tratados, principalmente aos 14 dias. Já os músculos não foram afetados pela laserterapia. A conclusão aponta para os benéficos da laserterapia sobre a recuperação morfológica do nervo ciático principalmente nos primeiros 14 dias após a lesão por axonotmese. Além de que a laserterapia, per si, não é capaz de influenciar a recuperação e a funcionalidade dos músculos acometidos.
