Anerkennung und Macht
(2021)
In der vorliegenden Untersuchung habe ich das Ziel verfolgt, einen sachlich-eigenständigen Beitrag für eine Debatte gegen Honneths kritische Gesellschaftstheorie zu leisten. In dieser Debatte wird Honneth dahingehend kritisiert, dass es ihm mit seiner kritischen Gesellschaftstheorie entgegen seiner eigenen systematischen Zielsetzung nicht gelingt, in modernen liberaldemokratischen Gesellschaften sämtliche Phänomene von sozialer Herrschaft kritisch zu hinterfragen. Denn soziale Anerkennung, die Honneth als Schlüsselbegriff für diese kritische Hinterfragung behandelt, bei der soziale Herrschaft in Verbindung mit sozialer Missachtung (als mangelnde soziale Anerkennung) steht, kann laut der Kritik faktisch selbst ein Medium für die Stiftung von sozialer Unterwerfung sein. Dies geschieht in Prozessen von Identitätsentwicklung, in denen soziale Anerkennung für Individuen als Anerkannte bestimmte Identitätsmöglichkeiten einräumt und auf diese Weise gleichzeitig andere Identitätsmöglichkeiten ausschließt, womit sie auf diese Identität einschränkend und insofern herrschend wirkt. Es handelt sich um eine Form von sozialer Herrschaft, die durch soziale Anerkennung gestiftet wird. Honneth zieht dem Vorwurf zufolge nicht in Erwägung, dass soziale Anerkennung bei Individuen als Anerkannte einen solchen negativen Effekt erzielen kann. Hieraus ergeben sich die Fragen, ob soziale Anerkennung in Prozessen von Identitätsentwicklung jeweils mit sozialer Herrschaft einhergeht und wie dieser Typus von sozialer Herrschaft kritisiert werden kann. Diese Fragen hat Honneth zuletzt in einem persönlichen Gespräch mit Allen und Cooke (als zwei Teilnehmerinnen der Debatte gegen Honneth) beantwortet. An dieser Stelle vertritt er mit beiden Gesprächsteilnehmerinnen die Auffassung, dass die Operation der Einschränkung von Identitätsmöglichkeiten an sich keine Operation darstellt, welche, wie sonst in der Debatte gegen seine kritische Gesellschaftstheorie behauptet wird, auf soziale Herrschaft zurückführt. Diese Auffassung beruht auf der Idee, wonach soziale Anerkennung sich in jenem praktischen Kontext nur unter der Bedingung als herrschaftsstiftend erweist, dass sie immanente Prinzipien verletzt, die substanziell kritische Maßstäbe definieren.
Mein Beitrag zu dieser Debatte gegen Honneth besteht auf der einen Seite in der Erklärung, dass sowohl jene Auffassung als auch jene Idee argumentativ mangelhaft sind, und auf der anderen Seite in der Ausführung des Vorhabens, diesen argumentativen Mangel selbst zu beheben. Gegen jene Auffassung behaupte ich, dass die drei Autoren in ihrem Gespräch nicht erläutern, inwiefern soziale Anerkennung nicht herrschend wirkt, wenn sie die Identitätsmöglichkeiten von Individuen als Anerkannte einschränkt, denn mit dieser Einschränkung wird vielmehr faktisch über diese Individuen geherrscht – die Debatte gegen Honneth, so zur Unterstützung dieser Ansicht, baut hauptsächlich auf ebendiesem Faktum auf. Gegen jene Idee habe ich fünf problematische Fragen gestellt und beantwortet, die Bezug eigentlich nicht allein auf diese Idee selbst, sondern überdies auf weitere, naheliegende Ideen nehmen, welche die drei Autoren angesprochen haben.
Previous research has shown that electrical muscle activity is able to synchronize between muscles of one subject. The ability to synchronize the mechanical muscle oscillations measured by Mechanomyography (MMG) is not described sufficiently. Likewise, the behavior of myofascial oscillations was not considered yet during muscular interaction of two human subjects. The purpose of this study is to investigate the myofascial oscillations intra- and interpersonally. For this the mechanical muscle oscillations of the triceps and the abdominal external oblique muscles were measured by MMG and the triceps tendon was measured by mechanotendography (MTG) during isometric interaction of two subjects (n = 20) performed at 80% of the MVC using their arm extensors. The coherence of MMG/MTG-signals was analyzed with coherence wavelet transform and was compared with randomly matched signal pairs. Each signal pairing shows significant coherent behavior. Averagely, the coherent phases of n = 485 real pairings last over 82 ± 39 % of the total duration time of the isometric interaction. Coherent phases of randomly matched signal pairs take 21 ± 12 % of the total duration time (n = 39). The difference between real vs. randomly matched pairs is significant (U = 113.0, p = 0.000, r = 0.73). The results show that the neuromuscular system seems to be able to synchronize to another neuromuscular system during muscular interaction and generate a coherent behavior of the mechanical muscular oscillations. Potential explanatory approaches are discussed.

The purpose of this study was to compare the effects of combined resistance and plyometric/sprint training with plyometric/sprint training or typical soccer training alone on muscle strength and power, speed, change-of-direction ability in young soccer players. Thirty-one young (14.5 ± 0.52 years; tanner stage 3–4) soccer players were randomly assigned to either a combined- (COMB, n = 14), plyometric-training (PLYO, n = 9) or an active control group (CONT, n = 8). Two training sessions were added to the regular soccer training consisting of one session of light-load high-velocity resistance exercises combined with one session of plyometric/sprint training (COMB), two sessions of plyometric/sprint training (PLYO) or two soccer training sessions (CONT). Training volume was similar between the experimental groups. Before and after 7-weeks of training, peak torque, as well as absolute and relative (normalized to torque; RTDr) rate of torque development (RTD) during maximal voluntary isometric contraction of the knee extensors (KE) were monitored at time intervals from the onset of contraction to 200 ms. Jump height, sprinting speed at 5, 10, 20-m and change-of-direction ability performances were also assessed. There were no significant between–group baseline differences. Both COMB and PLYO significantly increased their jump height (Δ14.3%; ES = 0.94; Δ12.1%; ES = 0.54, respectively) and RTD at mid to late phases but with greater within effect sizes in COMB in comparison with PLYO. However, significant increases in peak torque (Δ16.9%; p < 0.001; ES = 0.58), RTD (Δ44.3%; ES = 0.71), RTDr (Δ27.3%; ES = 0.62) and sprint performance at 5-m (Δ-4.7%; p < 0.001; ES = 0.73) were found in COMB without any significant pre-to-post change in PLYO and CONT groups. Our results suggest that COMB is more effective than PLYO or CONT for enhancing strength, sprint and jump performances.

Cross-education has been extensively investigated with adults. Adult studies report asymmetrical cross-education adaptations predominately after dominant limb training. The objective of the study was to examine unilateral leg press (LP) training of the dominant or nondominant leg on contralateral and ipsilateral strength and balance measures. Forty-two youth (10-13 years) were placed (random allocation) into a dominant (n = 15) or nondominant (n = 14) leg press training group or nontraining control (n = 13). Experimental groups trained 3 times per week for 8 weeks and were tested pre-/post-training for ipsilateral and contralateral 1-repetition maximum (RM) horizontal LP, maximum voluntary isometric contraction (MVIC) of knee extensors (KE) and flexors (KF), countermovement jump (CMJ), triple hop test (THT), MVIC strength of elbow flexors (EF) and handgrip, as well as the stork and Y balance tests. Both dominant and nondominant LP training significantly (p < 0.05) increased both ipsilateral and contralateral lower body strength (LP 1RM (dominant: 59.6%-81.8%; nondominant: 59.5%-96.3%), KE MVIC (dominant: 12.4%-18.3%; nondominant: 8.6%-18.6%), KF MVIC (dominant: 7.9%-22.3%; nondominant: nonsignificant-3.8%), and power (CMJ: dominant: 11.1%-18.1%; nondominant: 7.7%-16.6%)). The exception was that nondominant LP training demonstrated a nonsignificant change with the contralateral KF MVIC. Other significant improvements were with nondominant LP training on ipsilateral EF 1RM (6.2%) and THT (9.6%). There were no significant changes with EF and handgrip MVIC. The contralateral leg stork balance test was impaired following dominant LP training. KF MVIC exhibited the only significant relative post-training to pretraining (post-test/pre-test) ratio differences between dominant versus nondominant LP cross-education training effects. In conclusion, children exhibit symmetrical cross-education or global training adaptations with unilateral training of dominant or nondominant upper leg.
The aim of this case series approach was to analyze weekly changes in force-velocity relationship (FvR) parameters ((v) over bar, (F) over bar (0), (P) over bar (max)) and theoretical snatch performance (snatchth) assessed through a specific snatch pull test in preparation of the European and World Championships in 2 male elite weightlifters.
A second aim was to examine associations of training load (volume, volume load, average load), barbell -, and snatchth over a period of 2 macrocycles in preparation of the same competitions. FvR-parameters, snatchth, training load data, and body mass were assessed weekly over 40 weeks.
Using the smallest real difference approach, significant (p <= 0.05) decreases in (v) over bar (0) and increases in (v) over bar, (F) over bar (0), (P) over bar (max), and snatchth were found within macrocycles.
However, the large significant loss in body mass (approximate to 11%) in athlete 1 during macrocycle 2 represents most likely a main factor for diminished (P) over bar (max), and snatchth in macrocycle 2.
Based on cross-correlation analyses, barbell FvR-parameters and snatchth were significantly (p <= 0.05) associated with maximal strength, muscle power, and speed training load variables.
Moderate correlations (0.31-0.47) were found between training load and (P) over bar (max) and snatchth in athlete 2. It can be concluded that the applied training loads elicits improvements in <(P)(max) and snatchth because the athlete approached the main competitions.
However, because of the large loss in body mass, the relations between training load and barbell FvR-parameters and snatchth were less clear in athlete 1. It seems that a loss in body mass as a result of a change in bodyweight category mitigates <(P)over bar>(max) development during the macrocycle and hindered to reach peak snatchth at the main competitions.
The organisation of legislative chambers and the consequences of parliamentary procedures have been among the most prominent research questions in legislative studies. Even though democratic elections not only lead to the formation of a government but also result in an opposition, the literature has mostly neglected oppositions and their role in legislative chambers. This paper proposes to fill this gap by looking at the legislative organisation from the perspective of opposition players. The paper focuses on the potential influence of opposition players in the policy-making process and presents data on more than 50 legislative chambers. The paper shows considerable variance of the formal power granted to opposition players. Furthermore, the degree of institutionalisation of opposition rights is connected to electoral systems and not necessarily correlated with other institutional characteristics such as regime type or the size of legislative chambers.
