Objective: Drugs increase fall risk and decrease performance on balance and mobility tests. Conversely, whether biofeedback training to reduce fall risk also decreases scores on a published drug-based fall risk index has not been documented. Forty-eight community-dwelling older adults underwent either treadmill gait training plus visual feedback (+VFB), or walked on a treadmill without feedback. The Quantitative Drug Index (QDI) was derived from each participant's drug list and is based upon all cause drug-associated fall risk. Analysis of covariance assessed changes in the QDI during the study, and data is presented as mean ± standard error of the mean. Results: The QDI scores decreased significantly (p = 0.031) for participants receiving treadmill gait training +VFB (- 0.259 ± 0.207), compared to participants who walked on the treadmill without VFB (0.463 ± 0.246). Changes in participants QDI scores were dependent in part upon their age, which was a significant covariate (p = 0.007). These preliminary results demonstrate that rehabilitation to reduce fall risk may also decrease use of drugs associated with falls. Determination of which drugs or drug classes that contribute to the reduction in QDI scores for participants receiving treadmill gait training +VFB, compared to treadmill walking only, will require a larger participant investigation.

At any given running speed, weight support with a lower body positive pressure (LBPP) device (i.e. Alter-G treadmill) reduces V̇O2. However, it is unknown how application of LBPP during running impacts lactate metabolism, specifically lactate threshold. Purpose: To determine if body weight unloading with the Alter-G treadmill alters lactate threshold. Methods. Maximal aerobic capacity (V̇O2max) and lactate threshold (LT) was determined in 8 male subjects on an Alter-G treadmill at 100% and 80% body weight loading at 0% grade in a randomized crossover design. V̇O2max tests started at 7 mile h-1 and increase speed by 1 mile h-1 every 2 min till voluntary exhaustion and were separated by a minimum of 7 days. LT tests started at 5 mile h-1 and increased speed to 6, 7, 7.5, 8.0, 8.5, 9.0 (additional stages increase speed by 0.5 mile h-1) every 3 min until the subject reached ¡Ö85% of V̇O2max. LT tests were separated by a minimum 3 days. V̇O2, heart rate (HR), mean arterial blood pressure (MAP) and changes in Hct, [Hb], and total protein ([TP]) were determined on separate days in a randomized crossover design. Plasma lactate concentrations were determined from venous blood samples (4 ml) obtained at rest and during the last minute of each exercise stage. Lactate threshold was determined from a log-log plot of lactate concentration (mM) and relative V̇O2 (ml O2 min-1 kg-1 BM). Results. V̇O2max determined during running at 100% and 80% loading were similar (52.3 ± 0.9 and 52.7 ± 0.7 ml O2 min-1 kg-1 BM, respectively). The energy cost of running at 9 mile h-1 (all subjects completed stages between 5 and 9 mile h-1) was reduced by 12% at 80% body weight (37.2 ± 2.9 ml O2 min-1 kg-1 BM) compared to running at 100% body weight (42.3 ± 1.7 ml O2 min-1 kg-1 BM, <0.05). However, plasma lactate at 9 mile h-1 was similar during 80% and 100% body weight running (3.4 ± 0.4 and 3.1 ± 0.7 mM, respectively). Plasma lactate at a given V̇O2 was higher (p < 0.05) while running at 80% body weight compared to 100% body weight running. Calculated LT at 100% BW loading (36.3 ± 1.3 ml O2 min-1 kg-1 BM) was higher than 80% BW loading (32.2 ± 1.8 ml O2 min-1 kg-1 BM, p<0.05). During running at 80% BW HR was reduced compared to 100% BW running (p<0.05) however the MAP response was similar. During exercise the reduction in PV, at any given V̇O2 was larger at 80% BW compared to 100% BW running (p<0.001). Conclusion. During running, BW unloading with LBPP decreased the energy cost of exercise but not lactate levels. Body weight unloading caused a lowering of the LT. The reduction in whole body energy cost was not associated with a reduction in the lactate production since plasma lactate accumulation at a given speed was similar with and without LBPP.

Vid användning av Virtual Reality (VR) fanns en stor nackdel; Användare kunde inte utföra fullt rörelseomfång, framför allt förflyttning av olika slag; promenad, löpning, hopp samt sidosteg och gång baklänges. Användare förblev begränsade till utrymmets area och luft-rum. Antingen var användaren tvungen att strukturera om sitt utrymme eller så anpassades själva VR-programmet och dess headset för att kunna tillgodose detta problem på mest optimala sätt. Det har uppstått olika koncept av löpband som är inriktade för VR med syftet att lösa denna begränsning. Däremot var dessa koncept inte tillräckligt effektiva i att översätta normalt rörelsemönster till VR. Syftet med detta projekt var att vidareutveckla de etablerade koncepten med målet att ta reda på om en helt ny koncept-idé kunde fungera optimalt. Resultaten visade på att koncept-idén har potential men fortsatt arbete i en större omfattning skulle vara nödvändigt. / When using Virtual Reality (VR) there was a major drawback; Users could not perform full range of motion, especially locomotion of various kinds; walking, running, jumping as well as side steps and walking backwards. Users remained limited to the space's area and airspace. Either the user had to restructure their space or the VR-program itself and its headset were adapted to accommodate this problem in the most optimal way. Various treadmill concepts have emerged that are geared for VR with the aim of solving this limitation. However, these concepts were not effective enough in translating normal movement pattern to VR. The purpose of this project was to further develop the established concepts with the goal of finding out if a completely new concept idea could work optimally. The results showed that the concept idea has potential but continued work on a larger scale would be necessary.

Eight sedentary elderly subjects (X̅ age = 83.4yr), including two males and six females, were evaluated to determine the effects of a low intensity, chair-based exercise program on selected physiological parameters. Exercise sessions were held 3 alternate days per week, 45 minutes per session, for 8 weeks. Subjects were exercise tested before and after training using a modification of the Smith and Gilligan chair step test; this is a multi-level graded exercise test suitable for very old subjects with aerobic exercise capacities of approximately 2-4 METs. Upon completion of training, group data analyses showed no significant adaptations in resting heart rate or blood pressure, exercise heart rate or blood pressure, peak exercise performance, nor for subject rating of perceived exertion at a fixed exercise intensity. A significant increase (p < 0.05) was observed post-training in the immediate post-exercise blood lactic acid response. Separating subjects (n=4) into high (91% attendance) and moderate (49% attendance) compliers, statistically significant differences were found for training related changes in several physiological parameters. Between-group analysis also showed significant changes (p < 0.05) in the chair exercise performance time. Post-training, the high compliers improved their total exercise tolerance (time) by 33%, whereas the moderate compliers exercise time was 22% less as compared to pre-training. A significant difference (p < 0.05) was also observed between groups in their perception of effort at a fixed-load in the exercise test. After training, the high compliers judged their effort to be 12% less at a fixed load in the chair exercise test, while the moderate compliers showed no significant changes (p < 0.05). Blood lactic acid responses were significantly higher (p < 0.05) after training for the high compliance group but no such change was found in the HLa response of the moderate compliers. There were no significant changes in resting or exercise heart rate and blood pressure responses in either the high or moderate compliance groups. The results of this study suggest that physiological adaptations do not occur in old individuals in response to a low intensity exercise program. Given these preliminary findings, further investigations are indicated to determine the effects of increased frequency and duration of physical activity programs on additional physiological parameters. / Master of Science

The direct effect of spouse presence during graded exercise testing on anxiety and performance has not been previously delineated. Therefore, the purposes of this study were to (a) ascertain if spouse presence during graded exercise testing affects state anxiety or physiological performance variables, and (b) determine differences in psychological status between cardiac patients and healthy adults.

3 ABSTRACT Title: Comparison of lactate level at the same load in a swimming treadmill and on a bicycle ergometer Subject: 6 students (3 girls and 3 boys) from the first year of Bachelor's study at the Faculty of Physical Education and Sport of the Charles University at the age of 20,5 years ± 3 years took part in this research. Goal of the research: To compare demands of the load in the swimming flume with the same load on the bicycle ergometer, mainly at the level of the anaerobic threshold. Methods: We tested students by the method Critical Swimming Speed (CSS) for finding out their anaerobic threshold. Then students swam physical tests in the swimming treadmill - flume. The test consists of three 6 min parts. The first part of the swimming test was under the level of the CSS, the second part was at the level of the CSS and the third part was above the level of the CSS. We used the device for measuring the beat frequency (sport-testers) for obtaining information about changes of the heart rate (HR) during tests. Afterwards we accomplished tests on the bicycle ergometer, where we maintained HR at the same levels as in the load in the flume. We measured level of blood lactate (LA) after every 6 min part in the flume and on the ergometer. We statistically processed resulted values of LA by the Wilcoxon...

TITLE Alternative rehabilitation methods in therapy of Parkinson's disease OBJECTIVE The aim of work is to assemble new findings relating the rehabilitation of people with Parkinson disease. Furthermore to elaborate these information in form of literature search to allow their use in common practice. METHODS Up till now there were accomplished many studies which dealt with less common ways of therapy, but didn't find use in common practice. In this work these studies will be presented (in form of literature search). This work will be divided into two parts, where the first will sum up the issue of Parkinson's disease and the second part will deal with the alternative methods. Into this part studies detecting effects of dance therapy, tai-chi, qigong, treadmill training and box on symptoms of Parkinson's disease were chosen. Besides that, in discussion I plan on mentioning conventional therapy (rehabilitation) in Parkinson's disease as well as some guidelines written up in the Czech Republic.
