Neuromuscular function during drop jumps in young and elderly males

2011

The Hoffman reflex (H-reflex), indicating alpha-motoneuron pool activity, has been shown to be task - and in resting conditions - age dependent. How aging affects H-reflex activity during explosive movements is not clear at present. The purpose of this study was to examine the effects of aging on H-reflexes during drop jumps, and its possible role in drop jump performance. Ten young (26.8 ± 2.7 years) and twenty elderly (64.2 ± 2.7 years) subjects participated in the study. Maximal drop jump performance and soleus H-reflex response (H/M jump) 20 ms after ground contact were measured in a sledge ergometer. Maximal H-reflex, maximal M-wave, Hmax/Mmax-ratio and H-reflex excitability curves wer…

Neuromuscular Adaptations to Short-Term High-Intensity Interval Training in Female Ice-Hockey Players

2019

Kinnunen, J-V, Piitulainen, H, and Piirainen, JM. Neuromuscular adaptations to short-term high-intensity interval training in female ice-hockey players. J Strength Cond Res 33(2): 479-485, 2019-High-intensity interval training (HIIT)-related neuromuscular adaptations, changes in force production, and on-ice performance were investigated in female ice-hockey players during preseason. Fourteen Finnish championship level ice-hockey players (average age 22 ± 3 years) participated in 2½-week HIIT. Both spinal (H-reflex) and supraspinal (V-wave) neuromuscular responses of the soleus muscle were recorded before and after the training period. Static jump (SJ) and countermovement jump heights, plant…

Vedere. Lo sguardo di E.T.A. Hoffmann

2009

Vedere la folla attraverso una serie di inquadrature e con lo sguardo del voyeur, dello spettatore, dello scienziato, del visionario. Vedere la notte in un’oscurità che si popola di presenze inquietanti e sottrae il reale alla vista segnando la crisi della rappresentazione classica. Uno studio a quattro mani sul “vedere” in E.T.A. Hoffmann, corredato da un ricco apparato iconografico, che dimostra la centralità di questo autore sia sul versante di una teoria dello sguardo romantico sia su quello del rapporto tra dispositivi ottici e scrittura letteraria.

Descrizione e desiderio. I quadri viventi di ETA Hoffmann

2005

Descrizione e desiderio sono i due poli entro cui s’inscrive l’esperienza che E. T. A. Hoffmann, uno dei massimi scrittori del fantastico ottocentesco, fa della pittura antica e moderna. Raffaello e Salvator Rosa, Bosch e Van Dyck, la pittura di paesaggio fiamminga e la pittura sacra italiana costituiscono il canone implicito della sua narrativa. Attraverso un’analisi delle modalità di descrizione dei quadri nelle principali opere narrative di Hoffmann e la ricostruzione delle loro fonti visive, questo saggio ci restituisce una galleria immaginaria di figure che possono essere considerate protagoniste viventi dell’immaginario moderno e che hanno condizionato tutta la narrativa fantastica de…

Plantar flexor activation capacity and H reflex in older adults: adaptations to strength training.

2002

The purpose of this study was to investigate whether the voluntary neural drive and the excitability of the reflex arc could be modulated by training, even in old age. To this aim, the effects of a 16-wk strengthening program on plantar flexor voluntary activation (VA) and on the maximum Hoffman reflex (Hmax)-to-maximum M wave (Mmax) ratio were investigated in 14 elderly men (65–80 yr). After training, isometric maximum voluntary contraction (MVC) increased by 18% ( P < 0.05) and weight-lifting ability by 24% ( P < 0.001). Twitch contraction time decreased by 8% ( P < 0.01), but no changes in half relaxation time and in peak twitch torque were observed. The VA, assessed by twitch …

Copiste et créateur : les paradoxes de l'écrivain romantique

2015

International audience; L’article analyse deux célèbres figures de copistes romantiques, celle d'Anselme, le héros du Vase d'or de Hoffmann (1814), et celle d'Akaki Akakiévitch, le héros du Manteau de Gogol (1843). Il s’interroge sur le rapport entre copie et création à l’époque romantique.

Lebende Bilder. ETA Hoffmann und die Ikonographie der Heiligen Rosalie

2018

Die Mischung von Begierde und Kunst ist für Hoffmanns Bildbeschreibung charakteristisch: Statuen, die lebendig werden, Mädchen, die versteinern, Gemälde, die ihre Betrachter unwiderstehlich anziehen, Gestalten, die ein Leben auf der Schwelle zwischen Wirklichkeit und Darstellung führen, all dies sind Motive, welche die Hoffmannsche Erzählkunst in großem Ausmaß darbietet. Doch es handelt sich hier nicht nur um die Überlagerung von Liebesobjekt und Gemälde, von Begierde und Kunst, sondern vor allem und ausdrücklich um eine lästerliche Überlagerung von religiöser Ikonen (Heilige, Engel, Madonnen) und Sexualobjekten.
