Der Cours d’harmonie théorique et pratique von François Bazin dürfte zu den unbekanntesten musiktheoretischen Publikationen des 19. Jahrhunderts zählen, obwohl er zu den meistgelesenen Werken dieses Bereichs zumal im französischsprachigen Raum gehört. Dieses Buch nimmt aufgrund seiner qualitativ wie quantitativ herausragenden Eigenschaften eine Sonderstellung innerhalb der schier unübersehbaren Menge der in der zweiten Jahrhunderthälfte in Frankreich entstandenen theoretischen Lehrwerke ein: Bazins Lehrwerk, aus der Tradition Cherubinis und Halévys hervorgehend, kann als Musterexemplar einer Harmonielehre gelten, die alle relevanten Elemente des Unterrichts enthält, wie er um die Mitte des 19. Jahrhunderts am Pariser Conservatoire erteilt wurde. Zugleich kann Bazins kompakte, auf den Prinzipien des Generalbasses gegründete Darstellung bei der Vergegenwärtigung der Musik des 19. Jahrhunderts helfen, in ihrer Analyse und Vermittlung – als Kernaufgabe einer historisch informierten Musiktheorie.

To gain knowledge about children’s needs, the present study aimed to investigate the sport-related types of children using a exploratory, person-centered approach. In a multi-stage data analysis motivational orientation, physical self-concept, physical performance, and sport-related interest of 147 German children (9.46 years) were examined. First, three distinctive motivation and physical self-concept profiles based on motivation and physical self-concept were identified using cluster analysis (‘High self-concept, high motivation’; ‘Positive self-concept, self-determined motivation’; ‘Low self-concept, low motivation’). Motivation and physical self-concept profiles did not differ in physical performance significantly. In a second cluster analysis, four profiles of interest were identified and their relation to the motivation and physical self-concept profiles was examined. Among others it could be shown that half of children with low self-concept and motivation belong to an interest profile labelled „Little interested, sports and court games dislike“. Our findings suggest that various sports offers are needed based on three basic psychological needs, and children should be supported in making positive experiences to develop interest.

This randomized controlled crossover trial compared the short-term effects of creatine (CR) and beetroot juice (BJ) on resistance training performance and physiological responses across ∼72 h supplementation period. Eleven novice resistance-trained men completed bench press (BP) and back squat (BS) sets at 60–80% 1RM under CR, BJ, and placebo (PLA) conditions. Performance outcomes, intramuscular-oxygen-saturation (SmO2), peak heart rate (HR), and heart rate variability (HRV) were assessed. Individual modulation prevalence was also determined. CR significantly improved repetition performance at 80% 1RM in BP (d = 1.33) compared to PLA. Both CR and BJ produced moderate-to-very large effects on velocity with superior effect using BJ (d = 1.40–2.82 vs. PLA). Higher SmO2 (d = 1.74–2.9), lower peak HR (d = 0.83–2.74), and more favourable autonomic recovery (e.g. RMSSD: d = 0.91–2.99) were observed with BJ compared to both PLA and CR. Modulation analysis indicated greater proportions of meaningful individual adaptations, following BJ compared to CR. Overall, CR appeared to preferentially enhance mechanical performance, whereas BJ seemed to provide broader cardiometabolic and autonomic benefits.
