Körperliches und kognitives Training exekutiver Funktionen in Kindergarten und Schule

Executive functions, which can be encouraged by physical and cognitive training, are pivotally important for the social and emotional development of children and adolescents. For this reason future training of executive functions in kindergarten and school settings should be firmly anchored in both teacher education and continuing education courses as well as in school lessons. At the same time cognitive and neuroscientific studies analyzing the influence of sports on the learning performance of children and adolescents should be conducted under realistic learning conditions and hence in research schools.     

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.

Selbstkonzeptförderung im Sportunterricht

Previous intervention studies in school sports designed to test the socialisation hypothesis have tried to raise students’ self-concepts. However, this goal seems to be of questionable functionality: From both an educational and a psychological perspective, it would seem preferable to aim toward making self-concepts as realistic as possible. Underestimating self-concepts might impede performance-related behaviour, whereas overestimating might be dysfunctional, particularly in social interactions. This dichotomy is used to examine which manifestations of the self-concept physical education needs to promote from a psychological perspective. It creates a new perspective for future interventions designed to promote the self-concept in physical education.

K1和中国先要“K0”再谈市场

武林风、武林大会、WMA,当各种武术大赛在中国的荧屏中热播时,人们多少对台上武林高手剥抗的激烈程度感到不足。事实上,美国的MMA、日本的K1、泰国的泰拳等世界上著名格斗大赛,在吸引眼球方面确实远远超过了中国的武术比赛,只不过,中国的观众一直无缘亲睹。也许大家不知道的是,K1格斗大赛一度曾经离中国很近,而且,中国的散打选手一直在参加泰拳和K1的比赛,只不过由于成绩不突出,没有引起大家的注意。
