Auswirkungen des Cellvas-Mikrostromverfahrens auf die Leistungsfähigkeit bei Sportlern : Analyse möglicher Effekte auf ausgewählte psycho-physische Belastungsparameter im Leistungssport / Cellvas effects of micro current system to the performance of athletes : analysis of possible effects on selected psycho-physical stress parameters in competitiveGutschow, Ivonne January 2009 (has links)
Hohe Leistungsansprüche im Wettkampfsport erfordern von den Athleten eine hohe sportliche Belastbarkeit. Möglichkeiten die Trainingsumfänge und -intensitäten zu erhöhen, sind z.T. ausgeschöpft. So bestehen nach wie vor Bestrebungen neue Wege zu finden, um mögliche Leistungsreserven zu erschließen.
Elektrotherapieverfahren haben sich im klinischen Alltag, u.a. zur Behandlung von Traumata, bewährt und werden häufig zum Zweck der Analgesierung, Verbesserung der Gewebedurchblutung und zur Muskelstimulation angewandt. Deren Einsatz im adjuvanten Bereich der Trainingsbegleitung wurde bislang nur vereinzelt beschrieben. In der vorliegenden Studie wurden die Auswirkungen einer elektromagnetischen Anwendungsform auf ausgewählte psycho-physische Parameter untersucht (Kontrollgruppenvergleich mit placebokontrolliertem Design), um Aussagen über praxisrelevante Ansätze zur trainingsunterstützenden Betreuung abzuleiten. Es stellte sich die Frage, ob eine Intervention (15 x / 4 Wo.) mit frequenzmodulierten Wechselströmen im vorwiegend niederfrequenten Wirkungsspektrum (0-10000Hz, 5 μA / cm², CellVAS®) zu einer Beeinflussung der untersuchten Parameter führen und dahingehend nachhaltige leistungsfördernde oder -reduzierende Effekte erzielt werden könnten. Des Weiteren sollte geprüft werden, inwiefen die erhobenen Parameter (PWC170, Squat-Jump, Lateralflexion der Wirbelsäule und SF36®) aussagekräftig genug sind.
Die Wirksamkeit des Applikationsform wurde im Prä-Post-Vergleich vor (T1), nach (T2) und 4 Wo. nach Abschluss (T3, Nachhaltigkeit) der Intervention analysiert. Die Teilnehmer der Kontrollgruppe erhielten vergleichbare Applikationen im Placebomodus. Das Probandenkollektiv bestand aus gesunden Leistungssportlern, deren Sportarten einen hohen Kraftausdaueranteil enthielten (n=127). Die Gruppenzuteilung erfolgte teilrandomisiert in Haupt- (HG) und Kontrollgruppe (KG). Zudem wurden die Gruppen zusätzlich geschlechtsspezifisch getrennt.
Im Untersuchungsverlauf ließen sich Veränderungen für die Leistungsparameter PWC170 und Squat Jump erkennen. Inwiefern diese Abweichungen auf den Einfluss der Intervention mit frequenzmodulierten Wechselströmen im niederfrequenten Wirkungsspektrum zurückzuführen sind, konnte in dieser Untersuchung nicht eindeutig geklärt werden. Die nachgewiesenen Effekte ließen sich nach den zu Grunde liegenden wissenschaftlichen Standards nicht statistisch valide belegen. Der wissenschaftliche Nachweis einer mögliche Leistungsveränderung konnte nicht abschließend erbracht werden. Im therapeutischen Bereich hat die untersuchte Applikationsform, auf Basis der bestehen Studienlage, ihre Anwendung gefunden und kann bedenkenlos verwendet werden. Für den Einsatz als unterstützendes Verfahren in der sportlichen Praxis besteht nach wie vor Bedarf an validen, randomisierten Studien, die die Wirksamkeit der Applikationsform auf psycho-physische Parameter von Athleten nachhaltig belegen, bevor sie in der sportlichen Praxis Anwendung finden sollten. / High performance requirements in competitive sports require the athlete a high level of aerobic fitness. The training opportunities and scopes intensities increase, are z.T. exhausted. To persist The attempt to find new ways to potential performance reserves additional market opportunities.
Electrotherapy procedures have been in clinical practice, including to treatment of trauma, and are often proved for the purpose of analgesia, improvement of tissue perfusion and muscle stimulation applied. Their use in the field of adjuvant training support has so far been described only sporadically. In the present study, the effects were a electromagnetic application form on selected psycho-physical parameters examined (control group compared with placebo-controlled design) to statements about practical approaches to derive training support care. It turned the whether an intervention (15 x / 4 wk) with frequency currents in predominantly low-spectrum (0-10000Hz, 5 uA / cm ², CellVAS ®) to influence the parameters investigated, and so lead sustainable performance-enhancing or-reducing effects could be achieved. It should also be examined to what extent the parameters collected (PWC170, squat-jump, lateral flexion of the spine and SF36 ®) meaningful enough.
The effectiveness of the application form was in the pre-post comparison before (T1), after (T2) and 4 wk) after (T3, sustainability of intervention analysis. The participants in the control group received similar applications in the placebo mode. The group consisted of healthy volunteers, athletes, whose endurance sports a high proportion of included (n = 127). The group allocation was partially randomizedin in main-(HG) and ontrol group (KG). In addition, the groups were additionally gender separately.
In the course of the investigation could be changes for the performance parameters and PWC170 Squat Jump recognize. How far this Deviations on the impact of the intervention with frequency Due to currents in the low frequency spectrum are, could not be clarified clearly in this study. The effects could be detected by the underlying academic standards show not statistically valid. The scientific evidence of a possible change in performance could not be finally delivered. In the therapeutic range has examined the application form, are based on the Study location, found their application and can be safely used will. For use as a supportive procedure in the sports practice, there remains a need for valid, randomized studies evaluating the effectiveness of the application form on psycho-physical parameters of athletes demonstrate a sustained before Refer to the athletic practice should apply.

Exercise might be good for me, but I don't feel good about it : do automatic associations predict exercise behavior?Schweizer, Geoffrey, Bluemke, Matthias, Brand, Ralf, Kahlert, Daniela January 2010 (has links)
Models employed in exercise psychology highlight the role of reflective processes for explaining behavior change. However, as discussed in social cognition literature, information-processing models also consider automatic processes (dual-process models). To examine the relevance of automatic processing in exercise psychology, we used a priming task to assess the automatic evaluations of exercise stimuli in physically active sport and exercise majors (n = 32), physically active nonsport majors (n = 31), and inactive students (n = 31). Results showed that physically active students responded faster to positive words after exercise primes, whereas inactive students responded more rapidly to negative words. Priming task reaction times were successfully used to predict reported amounts of exercise in an ordinal regression model. Findings were obtained only with experiential items reflecting negative and positive consequences of exercise. The results illustrate the potential importance of dual-process models in exercise psychology.

Evaluation kommunaler Sportprojekte zur sozialen Integration von Heranwachsenden / Evaluation of community sports projects focusing on the social integration of adolescentsBorković, Vladimir January 2010 (has links)
Gegenstand der Studie ist die Evaluation eines kommunalen Sportprojekts. Die Forschungsarbeit entstand aus der wachsenden Erkenntnis heraus, dass es nicht mehr nur um die Entwicklung und Durchführung kommunaler oder sozialer Projekte geht, sondern zunehmend darauf ankommt, die Projektarbeit zu evaluieren, um ihren Einfluss auf die kommunale, soziale und personale Entwicklung zu prüfen und in der Folge die Implementierung zu optimieren. Die unterschiedlichen Schritte in der Definition des theoretischen Rahmens, der Datenanalyse sowie der Erarbeitung der evaluativen Empfehlungen wurden unternommen mit dem Anspruch auf Modellcharakter, um für zukünftige Evaluationsvorhaben entsprechende Standards zu setzen.
Die Grundidee des kommunalen Sportprojekts „Straßenfußball für Toleranz“ ist innovativ: Mädchen und Jungen erobern durch gemeinsames Fußballspielen den öffentlichen Raum. Sie spielen ohne Schiedsrichter und nach speziellen Regeln. Das Projekt richtet sich ausdrücklich an sozial benachteiligte Jugendliche und bezieht gleichermaßen Jungen wie Mädchen ein. / The objective of the study is the evaluation of a community sports project. The thesis originated from the growing perception that it is not only about initiating and implementing a communal or social project but that the focus is increasingly also on the evaluation of the project work in order to measure its impact on communal, social and personal development and to optimise the implementation as a consequence. The different steps in the definition of the theoretical framework, the data analysis as well as the formulation of the evaluative recommendations were conducted with the pretension to set standards for future evaluation projects.
The basic concept of the community sports project “Street Football for Tolerance” is innovative: boys and girls jointly conquer public spaces by playing football. They play without a referee and according to special rules. The project explicitly reaches out to socially disadvantaged adolescents, with the aim that boys and girls are equally involved.

The biomechanics of rugby place kickingAtack, Alexandra January 2016 (has links)
Approximately 45% of the points scored in international Rugby Union matches are the result of place kicks (Quarrie & Hopkins, 2015). However, the key technique characteristics underpinning this skill are not well understood. The aim of this thesis was therefore to investigate rugby place kicking technique and performance, and understand how these differ between successful and less successful place kickers. In order to objectively quantify place kick performance outcome from data collected in a laboratory environment, a novel performance measure representative of the maximum distance that any given place kick could be successful from was developed. This measure combined initial ball flight data with previously published aerodynamic forces and was shown to predict ball location with a mean error of 4.0%. Full body motion capture and ground reaction force data were then collected from 33 experienced (amateur to senior international level) kickers and three groups of kickers were identified based on their performance outcome: long, short, and wide-left kickers. Differences were observed in the initial ball flight characteristics between the three groups and specific aspects of technique were then analysed to understand how these different performance outcomes were achieved. The long and wide-left kickers used different strategies to achieve comparable forward kicking foot velocities and initial ball velocities. The wide-left kickers used a hip flexor strategy: greater positive hip flexor work which was facilitated by a stretch across the trunk at the top of the backswing, followed by longitudinal rotation throughout the downswing. In contrast, the long kickers used a knee extensor strategy: greater positive knee extensor work and a more consistent trunk orientation throughout the downswing. Although both strategies led to comparably high initial ball velocity magnitudes, the hip flexor strategy led to greater longitudinal ball spin and an initial ball velocity vector directed towards the left-hand-side. Kickers who achieve fast ball velocities but miss left could potentially benefit from technical interventions to address their trunk kinematics or development of their kicking knee extensor involvement. The long kickers achieved faster kicking foot and initial ball velocities than the short kickers. The long kickers took a more angled and faster approach to the ball compared with the short kickers. This enabled the pelvis to be less front-on at the top of the backswing, meaning that the kicking foot was further away from the ball at this point and subsequently travelled a longer path to initial ball contact. The long kickers also demonstrated greater horizontal whole-body CM deceleration between support foot contact and initial ball contact and performed greater hip flexor and knee extensor positive work than the short kickers during the downswing. Kickers who cannot generate fast ball velocities could potentially benefit from interventions to their approach direction and velocity, or from development of their kicking hip flexor and knee extensor involvement. This thesis has provided a comprehensive understanding of rugby place kicking technique and recommendations for both coaching practice and research.

Previous issue date: 2009-12-18 / Nowadays, professionals in the area of Physical Education are challenged to adapt the curriculum to the new guidelines and new demands of society. There will, the following question: "what alternative content taught in classes of Physical Education can be useful for agricultural education?" In handling this issue, this research supports the hypothesis that the agricultural college, the teaching of Physical Education has the need to give students more time through the significant inclusion of AFAN (Physical Activities of Adventure in Nature) and new perspectives to be included in the Agricultural College "Senator Carlos Gomes de Oliveira" (CASCGO). In order to get the general goal, which is try to identify activities related to AFAN that can be focused on teaching Physical Education and funded through an interdisciplinary perspective of agricultural education. The AFAN addressed several issues important to improving the quality of life: sports, corporate and legitimacy of Physical Education school, interdisciplinary, ecology, ecotourism, ecological trails, and even the interface between the Physical Education, Environmental Education and sustainable development. In addressing the methodological aspects of qualitative research, set a new proposal for alternative content in Physical Education in CASCGO. The strategies and deepening of research focus on the literature search, application of the same questionnaire and analysis. From the data collected, it identifies the categories as the evaluation of discipline in CASCGO, their working hours and content, the relationship between physical education and other areas of technical knowledge of the course in Agriculture, the interdisciplinary, and practical feasibility of the AFAN lessons of Physical Education. Analyzing the type of content that is practical and minister in the daily school's agricultural college, seeks to present an innovative fitness, showing a significant educational component for both the teacher and for the student, where he ceases to be a receiver only and skillful, Emphasizing the importance of physical activity in the nature of adventure in your daily life inside and outside the school context. The results of this study suggest that the implementation of the AFAN as prospect for the teaching of Physical Education in CASCGO is within the expectations of students due to shortage of recreation spaces, among which stand out as follows: trees, Ecological and Rock climbing Sports Track. In examining the prospects for the AFAN as CASCGO it was found that among their different ways, the ecological track is the most activity that provides an interface between the Physical Education and Environmental Education, fits perfectly well into our institution of agricultural education. Therefore, it is confirmed that the arrangements between the AFAN suggested, specifically the Ecological Trail is the most auspicious for the CASCGO. It is believed that the AFAN, as content of Physical Education in Agricultural Education can be significant in developing the education of our students. / Atualmente, os profissionais da ?rea de Educa??o F?sica s?o desafiados a adequar os curr?culos ?s novas diretrizes e novas demandas da sociedade. Surge, ent?o, o seguinte questionamento: ?qual conte?do alternativo, ministrado nas aulas de Educa??o F?sica, pode ser ?til para a educa??o agr?cola?? No tratamento dessa problem?tica, a presente investiga??o sustenta a hip?tese de que, no col?gio agr?cola, o ensino da Educa??o F?sica tem a necessidade de proporcionar aos alunos momentos mais significativos atrav?s da inclus?o das AFAN (Atividades F?sicas de Aventura na Natureza) como novas perspectivas a serem inseridas no Col?gio Agr?cola ?Senador Carlos Gomes de Oliveira?- CASCGO. A partir do objetivo geral, identificam-se atividades relacionadas ?s AFAN que podem ser focadas no ensino da Educa??o F?sica e subsidiadas numa perspectiva interdisciplinar do ensino agr?cola. As AFAN abordam diversos assuntos importantes para a melhoria da qualidade de vida: esportes, corporalidade e legitimidade da Educa??o F?sica escolar, interdisciplinaridade, temas transversais, ecologia, ecoturismo, trilha ecol?gica, e, at? mesmo a interface entre a Educa??o F?sica, Educa??o Ambiental e desenvolvimento sustent?vel. Ao abordar os aspectos metodol?gicos da pesquisa qualitativa, define-se uma nova proposta de conte?dos alternativos da Educa??o F?sica no CASCGO. As estrat?gias e o aprofundamento da investiga??o, compreendem a pesquisa bibliogr?fica, aplica??o de question?rio e a an?lise dos mesmos. A partir dos dados coletados, identificam-se as categorias como a avalia??o da disciplina no CASCGO, sua carga hor?ria e conte?do, a rela??o entre Educa??o F?sica e outras ?reas de conhecimento do curso t?cnico em Agropecu?ria, a interdisciplinaridade, viabilidade e pr?tica das AFAN nas aulas de Educa??o F?sica. Analisando o tipo de pr?tica e conte?do que se ministra no cotidiano escolar do col?gio agr?cola, procura-se apresentar uma Educa??o F?sica inovadora, evidenciando um componente curricular significativo tanto para o professor, quanto para o aluno, onde ele deixa de ser somente receptor e adestrado, manifestando a import?ncia das atividades f?sicas de aventura na natureza em seu cotidiano dentro e fora do ?mbito escolar. Os resultados desta pesquisa apontam que a implementa??o das AFAN como perspectiva para o ensino da Educa??o F?sica no CASCGO est? dentro das expectativas dos alunos devido ? car?ncia de espa?os de lazer, dentre as quais se destacam as seguintes modalidades: Arvorismo, Trilha Ecol?gica e Escalada Esportiva. Ao analisar as AFAN como perspectivas para o CASCGO constatou-se que dentre as suas diversas modalidades, a trilha ecol?gica ? a atividade que mais propicia uma interface entre a Educa??o F?sica e a Educa??o Ambiental, enquadrando-se perfeitamente em nossa institui??o de ensino agr?cola. Portanto, confirma-se que entre as modalidades de AFAN sugeridas, especificamente a Trilha Ecol?gica ? a mais prop?cia para o CASCGO. Acredita-se que as AFAN, como conte?do da Educa??o F?sica na Educa??o Agr?cola possa ser significativo no desenvolvimento da forma??o integral dos nossos alunos.

Vergleichende Untersuchungen von Leistungs- und Stoffwechselparametern im ergometrischen Test an Land und im Wasser / Comparative studies on performance and metabolic parameters in the ergometric test on land and in waterKarnahl, Brita January 2010 (has links)
Einleitung:
Vorliegende empirische Daten verdeutlichen, dass in der Fachwelt zwar weites gehend Einigkeit über die Wirkung des Mediums Wasser auf den Organismus in Ruhe (metabolisch und endokrin) besteht, aber differente Aussagen bei Immersion und Bewegung (hämodynamisch, metabolisch und endokrin) getroffen werden.
Wie unterscheidet sich die physische Beanspruchung an Land und im Wasser?
Gelten die allgemeingültigen Empfehlungen an Land zur Steuerung erwünschter Trainings- bzw. Belastungseffekte auch für aquale Bewegungs- und Trainingsformen?
Ergebnisse und Diskussion:
Die Herzfrequenz, der systolische Blutdruck und der Sauerstoffverbrauch waren in Ruhe (baseline) an der anaeroben Schwelle und während der Ausbelastung auf dem Land und im Wasser ähnlich. Der Respiratorische Quotient wurde gering reduziert, als die Probanden im Wasser trainierten. Die Glukose- und Laktatkonzentration wurden vermindert, wohingegen die freie Fettsäurekonzentration mit der Belastung im Wasser erhöht wurde. Wasserimmersion senkte die Adrenalin- und Noradrenalinkonzentration und erhöhte die vermehrte ANP-Produktion während der Belastung.
Belastungsinduzierte Anstiege endokriner Parameter (Adrenalin und Noradrenalin) sind im Wasser geringer ausgeprägt als an Land. Hinsichtlich der Stoffwechselregulation konnte beobachtet werden, dass ANP eine Rolle bei der Regulation des Fettstoffwechsels spielt.
Die Ergebnisse lassen vermuten, dass Belastungen im Wasser vor allem eine spezifische humorale und metabolische Antwort des Organismus entlocken. Belastungsinduzierte Anstiege endokriner Parameter (Katecholamine) im Wasser sind geringer ausgeprägt als an Land.
Immersions- und Belastungseffekte scheinen teilweise konträre Reize zu sein.
Es sind daher weiterhin experimentelle Untersuchungen notwendig, um die Regulationsmechanismen des Organismus zur Kompensation eines erhöhten venösen Rückstroms bei Immersion ohne und vor allem mit Bewegung zu klären.
Auf Grund der geringen Unterschiede in der hämodynamischen Reaktion des Körpers bei vergleichbarer körperlicher Belastung Land vs. Wasser kann sich an den allgemeingültigen Empfehlungen an Land zur Steuerung erwünschter Trainings-bzw. Belastungseffekte auch für aquale Bewegungs- und Trainingsformen orientiert werden. / Introduction:
The empirical data we have shows clearly that that there may be a large area of agreement among professionals on the effect of water as a medium on the organism at rest (metabolic and endocrinal), but different conclusions have been drawn about immersion and exercise (hemodynamic, metabolic and endocrinal).
How does physical stress differ on dry land and in the water?
Do the general recommendations on land apply to control of desired training or stress effects as well as for aquatic types of exercise and training?
Results and discussion:
The heart rate, systolic blood pressure and uptake of oxygen at rest (baseline) were similar at the anaerobic threshold and during a workout on land and in the water. The respiratory quotient was slightly reduced when the test subjects were training in the water. Their glucose and lactate concentration was lowered, whereas the free fatty acid concentration was raised during physical workload in the water. Water immersion lowered adrenalin and noradrenalin concentration and raised the increased production of ANP during workload.
Load-induced increases in endocrinal parameters (adrenalin and noradrenalin) are less marked in water than on land. When it comes to regulating the metabolism, it was possible to observe that ANP plays a role in regulating lipid metabolism.
The results suggest that workloads in water elicit especially a specific humoral and metabolic response from the organism. Load-induced increases of endocrinal parameters (catecholamines) in water are less marked than on land.
Immersion and load effects appear to be partly contrary stimuli.
For this reason, further experimental tests are required in order to clarify the organism’s regulatory mechanisms to compensate for increased venous back current when immersed without and especially with exercise.
Because of the slight differences in the body’s hemodynamic response at comparable physical loads on land versus water, the generally accepted recommendations to control the desired training and physical workload effects on land can be used as the basis for aquatic types of exercise and training as well.

Aktivitäts- und Herzfrequenz-Monitoring zur Erfassung der Bewegungszeit und der Bewegungsintensität im schulischen und außerschulischen Kontext von Grundschülern im Land Brandenburg / Activity and heart rate monitoring to detect the movement of time and intensity of movement in and outside the school context of elementary school students in the state of BrandenburgHöhne, Janet January 2011 (has links)
"Kinderwelt ist Bewegungswelt" (Schmidt, 1997, S. 156, zitiert nach Schmidt, Hartmann-Tews & Brettschneider, 2003, S. 31). Das kindliche Bewegungsverhalten hat sich bereits im Grundschulalter verändert, so dass sich Bewegungsaktivitäten von Kindern erheblich unterscheiden und keineswegs mehr verallgemeinert werden können.
Richtet man den Fokus auf die Frage „Wie bewegt sind unsere Kinder?“ so scheint diese von den Medien bereits beantwortet zu sein, da dort von ansteigendem Bewegungsmangel der heutigen Kinder gegenüber früheren Generationen berichtet wird. Wenn es in den Diskussionen um den Gesundheitszustand unserer Kinder geht, nimmt die körperlich-sportliche Aktivität eine entscheidende Rolle ein. Bewegungsmangel ist hierbei ein zentraler Begriff der in der Öffentlichkeit diskutiert wird. Bei der Betrachtung der einzelnen Studien fällt auf, dass deutliche Defizite in der Messung der körperlich-sportlichen Aktivität bestehen. Zentraler Kritikpunkt in den meisten Studien ist die subjektive Erfassung der körperlich-sportlichen Aktivität. Ein Großteil bisheriger Untersuchungen zum Bewegungsverhalten basiert auf Beobachtungen, Befragungen oder Bewegungstagebüchern. Diese liefern ausschließlich zum Teil subjektive Einschätzungen der Kinder oder Eltern über die tatsächliche Bewegungszeit und -intensität. Das objektive Erfassen der Aktivität bzw. Inaktivität ist zwar seit einigen Jahren zentraler Gegenstand vieler Studien, dennoch gilt es, dieses noch sachkundiger zu lösen, um subjektive und objektive Daten zu vergleichen. Um dem Bewegungsmangel der heutigen Kinder entgegenzuwirken, sind empirisch abgesicherte Erkenntnisse über die Bedingungsfaktoren und die Folgen des veränderten Bewegungsverhaltens dringend nötig.
Die Quer- und Längsschnittuntersuchung umfasst die Bereiche Anthropometrie, die Erfassung der körperlich-sportlichen Aktivität und die Herzfrequenzmessung über 24h. Für die Studie konnten 106 Jungen und Mädchen im Zeitraum von Januar 2007 bis April 2009 rekrutiert und überprüft werden. Die physiologischen Parameter wurden mit Hilfe des ACTIHEART-Messsytems aufgezeichnet und berechnet. Die Ergebnisse zur körperlich-sportlichen Aktivität wurden in die Untersuchungsabschnitte Schulzeit gesamt, Pause, Sportunterricht, Nachmittag und 24h unterteilt. Durch das Messsystem werden die Bewegungsaktivität und die Herzfrequenz synchron aufgezeichnet. Das System nimmt die Beschleunigungswerte des Körpers auf und speichert sie im frei wählbaren Zeitintervall, Short oder Long Term, in Form von „activity counts“ ab. Das Messsytem berechnet weiterhin die Intensität körperlicher Aktivität. / "Children's World is the world movement" (Schmidt, 1997, p. 156, quoted by Schmidt, Hartmann-Tews & Brettschneider, 2003, p. 31). The child's physical activity has changed already in elementary school, so that physical activity of children vary considerably and can not be more generalized.
If we turn our focus to the question "What moves are our children?" So this seems to have been answered by the media, because there is increasing lack of physical activity reported by today's children from previous generations. When it comes to discussions about the health of our children, taking the physical and sporting activity plays a decisive role. Lack of exercise is a key term here is in the public's debate. When examining the individual studies is striking that significant deficiencies exist in the measurement of physical and sporting activity. The central point of criticism in most studies is the subjective detection of physical and sporting activity. A majority of previous studies on physical activity based on observations, interviews, or movement diaries. These provide only partly subjective assessments of the children or parents about the actual movement of time and intensity. The objective recording of activity or inactivity, although in recent years, the central subject of many studies, yet it is true, this knowledgeable yet to be resolved in order to compare subjective and objective data. To counteract the lack of movement of today's children, empirically based insights into the determinants and consequences of changes in physical activity are urgently needed.
The cross-sectional and longitudinal study covers the areas of anthropometry, the collection of physical and sporting activity and heart rate measured over 24 hours. For the study, 106 boys and girls in the period January 2007 to April 2009 are being recruited and examined. The physiological parameters were recorded using the ACTIHEART-measuring systems and calculated. The results for physical and sporting activity were divided into the total school study sections, breaks, physical education, and 24 afternoon. By the measurement system's physical activity and heart rate recorded synchronously. The system records the acceleration of the body and stores it in the selected time interval, from Short or Long Term, in the form of "activity counts". The measurement system calculates the intensity of physical activity continue.
