Körperbild und Körperzufriedenheit im Leistungssport

The controversy surrounding the role of competitive sports in the development of eating disorders has increased in recent decades. There are inconsistent findings in the literature concerning the relationship between eating disorders and competitive sports, especially aesthetic sports. The aim of this study was therefore to assess eating disorder-related psychopathology in a sample of competitive figure skaters (FS) representative for competitive aesthetic sports. Special attention is paid to the investigation of body image and body satisfaction. Patients with anorexia nervosa (AN) and a healthy control group (CG) served as comparison groups. None of the FS met the complete diagnostic criteria for an eating disorder. Furthermore no significant differences were observed between the FS and the CG regarding body image and body satisfaction. However, a significant difference was detected compared to the AN patients. Our results underline the necessity for a differentiated analysis and careful diagnostics of sport-specific aspects when considering eating disorder-related psychopathology in competitive sports.     

Sportökonomie und Sportmanagement zwischen Wirtschaftswissenschaft und Sportwissenschaft?

Discussions about the relationship of sports science to each of its disciplines can be traced back to the years of establishment of sports science. For the comparably young discipline of sports economics these considerations are currently still lacking. Historically, besides applying economic approaches to sports one can also identify non-economic traditions of dealing with economic phenomena in sports. Within both lines of tradition different terms for the phenomena to be examined are used. Reflecting the development of these two lines of tradition of sports economics with respect to the established philosophical positions of Popper’s falsificationism, to Kuhn’s paradigmatic development as a consequence of normal science and scientific revolution, as well as to Lakatos’ methodology of scientific research programs, a number of implications arise for the development status of sports economics as an economic discipline both for its position in relation to sports science and economic science and regarding developments of further theories.

Mobilitätskonzept in Sporttherapie und -wissenschaft

The international classification of functioning, disability and health (ICF) is a concept developed for the healthcare sector by the World Health Organization, which considers the health problems of a person with respect to functional ability, impairments and context factors. Mobility is an important basic functional element, central health criterion and an important prerequisite for participation in social life. In addition to all routinely relevant daily movements (e.g. walking, lifting and carrying), activities at the workplace and sport-related activities are also taken into consideration. Because mobility is internationally established as a central criterion of health by the World Health Organization, this results in a series of interesting connecting factors from sport scientific and kinesthesiological perspectives: movement is the central object of kinesthesiology and exercise therapy. Mobility is of exceptional importance for human existence and dealing with the world at large. Analogous to the discussion on basic motor competences with respect to compatibility in educational sciences, utilization of the ICF can be the basis for a common language in the medical-therapeutic milieu. The orientation to mobility allows the targets, contents and methods of exercise therapy to be addressed for the context-related importance in individual cases. This article presents possible perspectives for sport scientific disciplines, sport and exercise therapy with respect to mobility. The importance of mobility for health is emphasized and the relevance is discussed based on the development of diagnostic procedures and application of therapy.     

Fördert ein multidimensionales Gesundheitssportprogramm kognitive und motorische Fähigkeiten im höheren Erwachsenenalter?

Research on successful aging has shown that physical training can have positive effects on cognitive and motor functions in the elderly. The article describes a study involving a 12-week multidimensional exercise program (endurance, strength, flexibility and relaxation) with one session per week which was established for older adults (60 years onwards). Cognitive training (e. g. attention, concentration and memory) was additionally targeted in each exercise session. The exercise program was evaluated by different standardized tests regarding its effects on motor and cognitive performance as dependent variables. In a randomized controlled trial with experimental and waiting control group two points of measurement were conducted. The results showed a significant increase in fitness parameters (endurance, strength and dynamic balance) for the experimental group in contrast to the control group. The expected significant increase for cognitive functions was not found. There is still not enough known about the relationship between cognitive function and physical activity in older adults.     

Buddy up: the Köhler effect applied to health games

The present investigation examined the K?hler motivation gain effect in a health game using an absent partner, presented virtually. The K?hler effect occurs when an inferior team member performs a difficult task better in a team or coaction situation than one would expect from knowledge of his or her individual performance. The effect has been strongest in conjunctive task conditions in which the group's potential productivity is equal to the productivity of its least capable member. Participants were randomly assigned to one of four conditions (individual control, coaction, additive, and conjunctive) in a 4 (conditions) ? 2 (gender) factorial design and performed a series of isometric plank exercises within an exercise game. They performed the first series of five exercises alone holding each position for as long as they could, and, after a rest period, those in the partner conditions were told they would do remaining trials with a same-sex virtual partner whom they could observe during their performance. The partner's performance was manipulated to be always superior to the participant's. Results showed that task persistence was significantly greater in all experimental conditions than in the individual control condition. The conjunctive condition was no more motivating than either the additive or coactive conditions. Results suggest that working out with virtually present, superior partners can improve persistence motivation on exercise game tasks.     

Die Körperzusammensetzung von Hobbygamern im Vergleich zu deutschlandweit erhobenen Referenzdaten

About two thirds of adults in Germany are overweight or obese. While an increase in the consumption of high-calorie food is considered the main cause, the influence of various forms of sedentary activities is still controversially discussed. The aim of the present study is to compare the body composition of hobby gamers with reference data collected throughout Germany and to examine the effects of intensive use of computer games (gaming) on body composition. A total of 68 male participants of a computer game event aged 18–46 years (27.9 years; 180.1?cm; 83.5?kg; BMI 25.7) were examined for fat mass, body cell mass, extracellular mass, body water and phase angle using bioelectrical impedance analysis (BIA, Nutriguard MS type, data input). Ten test persons were retested by means of segmental 8?electrode BIA after a 24?h interval during their visit to the event. As a reference sample, data from 278 male adults of the same age (27.9 years, 179.4?cm; 78.8?kg; BMI 24.5) were collected in 168 locations throughout Germany. The hobby gamers reported on average 37.1?h screen media usage per week. Compared to the reference sample, they showed a slightly higher body cell mass index (p?<?0.01, T?=?4.07), but no differences in fat mass index (p?=?0.96, T?=?0.05) and phase angle (p?=?0.90, T?=?0.12). A significant increase in body water (T₀: 48.2?l, T₀₊₂₄?_h: 49.3?l; p?=?0.04, T?=?2.39) and decrease in the phase angle of the lower extremities (T₀:?7.40, T₀₊₂₄?_h: ?6.85; p?<?0.01, T?=?5.40) was observed in the 24?h retest. Compared to the reference data collected throughout Germany, hobby gamers show no differences in health-relevant parameters of body composition. Nevertheless, after intensive gaming, a short-term increase in the amount of extracellular water in the lower extremities was found. Due to these disturbances in the water balance, the consequent execution of movement breaks during gaming is important.     

Match-Qualität und ehrenamtliches Engagement in Sportvereinen

Recent studies have found a positive link between match quality, i.?e., the congruence of motives for doing volunteer work and the actual experiences, and the satisfaction of volunteers. We studied determinants of match quality based on data of volunteers in sports clubs from Rhineland–Palatinate. We found that match quality is positively correlated with different forms of support and recognition by sports clubs, whereas support by the employer plays only a minor role. We furthermore found path dependencies: previously gained skills and the question who or what affected the initial decision of doing volunteer work influence match quality. Match quality is lower if a lack of volunteers is perceived within a club. On average, match quality is higher for volunteers who do operative work than for volunteers in executive positions.     

Inhalte und Strukturen prototypischer Merkmale in Fußballmannschaften

Members of a social group possess a shared social identity, which is individually represented as the group prototype. The prototype is the individual cognitive representation of all attributes, which best describes the group from the group members’ point of view. The aim of the study was to gather those attributes provided by group members of a soccer team and subsequently to describe and categorize them by means of a content analysis. Using one single open question, a total of 1581 attributes were assessed through n?=?278 soccer players (67?% male; M?=?23.5 years, SD?=?5.0 years) from 20 soccer teams. The data analysis was based on the qualitative content analysis described by Mayring (2010). Results show that the attributes mentioned by the team members can be divided into four distinct categories (social, psychological, sport specific, ecological). These categories result from intragroup synchronisations. Future research should examine which categories and subcategories seem to best represent the prototype in soccer teams.
