abstract: Among its many roles in the body, ascorbic acid functions as a cofactor in carnitine and catecholamine synthesis, metabolites involved in fat oxidation and mood regulation, respectively. Given that fat oxidation and mood affect one's feelings of vigor, I hypothesized that those with lower levels of plasma ascorbic acid would be less likely to exercise at high levels than individuals with adequate or high levels of vitamin C. To test this, I conducted a double-blind, placebo-controlled intervention. A group of healthy, non-smoking males between the ages of 18 and 40 were put on a vitamin C-restricted diet for two weeks and then randomized to a control group that received placebo capsules for six weeks or an intervention group that received 500 mg of vitamin C daily for six weeks. The men were restricted from eating foods high in vitamin C, instructed to wear a pedometer daily and to record their step counts, and to take a pill daily (either the placebo or vitamin C supplement). Unexpectedly, the subjects receiving the intervention had lower step counts than the control group; the control group, rather than the vitamin C group, significantly (p=0.017) increased their steps at week 8 compared to week 2. However, I also estimated daily Metabolic Equivalent Tasks (METs), and subjects receiving the placebo had lower MET outputs than subjects receiving vitamin C at the end of the trial, in spite of having higher step counts. This means the intensity of their activity was higher, based on METs expenditure. Additionally, depression scores (POMS-D) as measured by the Profile of Mood States (POMS) questionnaire were significantly higher (p=0.041) among subjects receiving the placebo at the end of the study. These latter results are consistent with my expectations that subjects with higher levels of plasma vitamin C would have improved mood and higher energy output than subjects with low levels of vitamin C. / Dissertation/Thesis / M.S.

Title: Affective mood states of the patient in physiotherapy care Objectives: The aim of the theoretical part is to summarise the available findings about the chosen physiotherapeutical procedures, the psychosomatic attitude to the patients, the emotional states, the affective mood states and the possibilities how to influence them. The aim of the practical part is to evaluate the affective mood states of the patients before and after the physiotherapy care. Methods: The research involves twenty-five patients who underwent physiotherapeutical care in the centres specialised in holistic treatment. Their state was observed with the help of the POMS Questionnaire. The patients filled in the forms before and after the physiotherapeutical intervention with the psychosomatic attitude. The non-parametric version of the Wilcoxon's test was used for the evaluation of the differences of the dependent selected groups. Results: The results have proved all of the three hypotheses. After the physiotherapeutical intervention the current psychical state changed, the decrease of the tension, depression, anger, fatigue and confussion was significant. The vitality was increased significantly. Keywords: Emotional states, physiotherapy, psychosomatic attitude, POMS

The aim of the practical part is to evaluate the affective mood states of the patients before and after the physiotherapy care. Methods: The research involves fifty patients who underwent physiotherapeutical care in the centres specialised in holistic treatment. Their state was observed with the help of the POMS Questionnaire. The patients filled in the forms before and after the physiotherapeutical intervention with the psychosomatic attitude.

Purpose To evaluate the information provided by Polar Vantage V, a new generation of heart rate monitor/watch (HRM-watch) to the user, regarding the acute:chronic load ratio (ACLR), based onthe external and internal load measures and examine the measures against psychological and physiological measures before and during a threshold test with VO2max testing. Method A five-week prospective study with results and data collected during and after four normal training weeks and during a fifth week with a very high training load. The results from HRM-watchwere then evaluated against the results from physiological and psychological tests. Eight endurance runners were recruited. Results Differences in ACLR against the differences in HRR show a R2 value of 0.77 (p<0.05). ACLR signicantly increased with an average of 0.33 from 0.93 to 1.26 (p=0.003, 95 % CI= 0.17 {0.49). Differences in ACLR against dierences in total mood disturbance (TMD) from POMS showin regression analyses a R2value of 0.67 (p=0.05). No significant difference was noted in neither resting HRV (p=0.3, 95% CI= -22.2 { 8.5) or standing HRV (p=0.15, 95% CI= - 4.15 { 20.8). Conclusion Based on the result of the present study it can be concluded that training status, well-being and present mood state can be predicted fairly good with the information from the internal and external load measurements from the Polar Vantage V. However, the power of present exploratory study was low due to a low number of included participants. Future research with greater number of participants and an improved study design is needed to verify these interesting findings.

The purpose of this study was to determine if fitness levels of individuals affect cognitive function. This study seeks to show how response inhibition and accuracy are affected following a mentally fatiguing task. Response inhibition refers to the suppression of actions that are inappropriate and that interfere with goal driven behavior. Response inhibition in reference to the continuous performance task (CPT) is measured in false clicks. The tasks for the CPT were completed after either a controlled period of rest or moderate-intensity exercise. Subjects were either Georgia Tech Division I track athletes or students leading a sedentary lifestyle. All subjects participated in two test protocols. Athletic subjects completed the resting protocol first, while sedentary subjects completed the exercise protocol first. Subjects reported to the lab following an overnight fast. They completed an initial set of paper work and signed a consent form, filled out a 24 hour history form and completed a Profile of Moods States (POMS) and Visual Analog Scale (VAS) form. Subjects then took a 20-minute (CPT). The CPT is a neuropsychological test that measures an individual’s sustained and selective attention. The length of the test is 20 minutes in order to induce mental fatigue. The goal of the test is to click in a white box when the letter T is seen. Immediately after subjects filled out a secondary set of paperwork. Once paper work was complete subjects either rested or exercised for 35 minutes. If subject was classified as an athlete, trial 1 was rest, while trial 2 was exercise. If subject was classified as a sedentary student, trial 1 was exercise, and trial 2 was rest. After the subject completed either the cycling or resting portion they repeated the CPT for five minutes. It was hypothesized that that the effects of moderate exercise positively affect the subject’s performance on the CPT. I expect false clicks following the 5 minute CPT to be lower after exercising. I hypothesize that for both groups their accuracy should be higher after moderate cycling and that higher fitness level should decrease the level of mental fatigue experienced throughout the CPT.

Aim of paper is to find out what effects do physical exercises have on the psychical part of the person. Theoretical part speaks about psychology and emotions from the psychical view, and also from the biological view. It speaks about the effect of sport, group mentality and the way people in a group perceive the sport. It also mentions biological processes in the body and the substances that are made during the physical exertion. Methodical parts speaks about how we will put out hypothesis to the test. That is how, where, how long and under what circumstances will we do our experiement, and how will we evaluate it. Conclution is made of results, which containt tables and graphs with collected data and their explanation in text, evaluation and personal comments. Annexes contain the prototype of the used questionnaire. Results showed, that theoretical hypothesis, that physical activities are beneficial for a human, and statistical hypothesis both proved correct, and statistical one in 83,3% of the cases.

Title: Possibilities of Non-invasive Control of Hypoxic Training Objectives: To find out whether there is a statistically significant change in mood dynamics measured by the POMS questionnaire while staying and training in a natural hypoxic environment (LHTH), compared to staying and training in normoxy. To compare and verify other non-invasive methods of controlled training in natural hypoxia. Methods: The research has the character of a quasi-experiment with a plan of repeated measurements. As a method of data acquisition, questioning was carried out using a standardized POMS questionnaire, analysis of training documentation. In the selected persons heart rate measurements and analysis of blood biochemical examination records were also done. An additional interview was included. There are two case studies. Results: A statistically significant difference in mood states was observed in the second week of the training camp, when a naturally hypoxic environment reduced the Energy Index and increased the Total Mood Disturbance of athletes. Casuistic investigations did not find any correlation between athletes' reduced performance and changes in the morning resting heart rate or biochemical blood analysis. However, a correlation between the decrease in performance and the overall mood disorder was...
