Contraction with shortening during stimulation or during relaxation : how do the energetic costs compare?
Lou, Fang; Curtin, N.A.; Woledge, R.C. (1998-10)White muscle fibres from dogfish were used to compare the energetic costs of shortening by fully active muscle and by relaxing muscle. The muscle preparation was tetanized for 0.6 s and shortened either during stimulation ... -
Distinguishing Metabolic Heat from Condensation Heat during Muscle Recovery
Lou, Fang; Curtin, N.A.; Woledge, R.C. (1998)When a thermopile is used to measure the heat production of isolated muscle, the muscle is surrounded by gas saturated with water vapour, initially in equilibrium with the muscle. After contraction, the osmolarity of the ... -
Elastic energy storage and release in white muscle from dogfish scyliorhinus canicula
Lou, Fang; Curtin, N.A.; Woledge, R.C. (1999-01)The production of work by the contractile component (CC) and the storage and release of work in the elastic structures that act in series (the series elastic component, SEC) with the contractile component were measured ... -
The Energetic Cost of Activation of White Muscle Fibres from the Dogfish Scyliophinus Canicula
Lou, Fang; Curtin, N.A.; Woledge, R.C. (1997)The energetic cost of activation was measured during an isometric tetanus of white muscle fibres from the dogfish Scyliorhinus canicula. The total heat production by the fibres was taken as a measure of the total energetic ... -
Heat production and oxygen consumption during metabolic recovery of white muscle fibres from the dogfish Scyliorhinus canicula
Lou, Fang; van Der Laarse, W. J.; Curtin, N.A.; Woledge, R.C. (2000-04)Oxygen consumption and heat production were measured during contraction and recovery of isolated, white muscle fibres from dogfish (Scyliorhinus canicula) at 19 degrees C. The contraction period consisted of 20 isometric ... -
Isometric and isovelocity contractile performance of red muscle fibres from the dogfish Scyliorhinus canicula
Lou, Fang; Curtin, N.A.; Woledge, R.C. (2002-06)Maximum isometric tetanic force produced by bundles of red muscle fibres from dogfish, Scyliorhinus canicula (L.), was 142.4+/-10.3 kN m(-2) (N=35 fibre bundles); this was significantly less than that produced by white ... -
Shortening during stimulation vs. during relaxation : How do the costs compare?
Lou, Fang; Curtin, N.A.; Woledge, R.C. (1998)White muscle fibres from dogfish were used to investigate the energetic cost of shortening by fully active muscle and by relaxing muscle. The muscle preparation was tetanized for 0.6 s and shortened by 1 mm (about 15% L0) ... -
Sustained performance by red and white muscle fibres from the dogfish Scyliorhinus canicula
Curtin, N.A.; Lou, Fang; Woledge, R.C. (2010-06-01)The mechanical performance of red and white muscle fibres from dogfish was compared during a long series of contractions with sinusoidal movement or under isometric conditions at 12 degrees C (normal in vivo temperature). ...
