Sustained performance by red and white muscle fibres from the dogfish Scyliorhinus canicula
(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). ...
Isometric and isovelocity contractile performance of red muscle fibres from the dogfish Scyliorhinus canicula
(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 ...
Heat production and oxygen consumption during metabolic recovery of white muscle fibres from the dogfish Scyliorhinus canicula
(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 ...
Contraction with shortening during stimulation or during relaxation : how do the energetic costs compare?
(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 ...
Shortening during stimulation vs. during relaxation : How do the costs compare?
(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) ...
The relationship between the intracellular Ca2+ transient and the isometric twitch force in frog muscle fibres
(1996-09)
The calcium-sensitive fluorescent indicator fluo-3 was used to monitor the intracellular free calcium concentration ([Ca2+]i) during isometric twitches in twenty-nine single muscle fibres from the anterior tibialis muscle ...
The effects of 2,3-butanedione monoxime (BDM) on the force-velocity relation in single muscle fibres of the frog
(1995-04)
The effects of 2,3-butanedione monoxime (BDM) on the force-velocity relation were studied in single fibres from the anterior tibialis muscle of Rana temporaria (2.2 microns sarcomere length, temperature 1.9-2.4 degrees C). ...
Moderate fatigue studied at great sarcomere lengths in frog single muscle fibres
(1994-10)
Single fibres from the anterior tibialis muscle of Rana temporaria (temperature, 2-3 degrees C) were moderately fatigued at a prestretched sarcomere length (approximately 3.6 microns) by reducing the intervals between 2 s ...
Depression of tetanic force induced by loaded shortening of frog muscle fibres
(1993-07)
1. Single fibres isolated from the anterior tibialis muscle of Rana temporaria were allowed to shorten against a high load during a 2.5-4.0 s fused tetanus (1-3 degrees C) and the maximum force produced at the short length ...
Myofibrillar fatigue versus failure of activation during repetitive stimulation of frog muscle fibres
(1992-11)
1. Single fibres isolated from the anterior tibialis muscle of Rana temporaria (temperature, 2-5 degrees C; sarcomere length, 2.10 microns) were fatigued using two separate protocols that led to different degrees of ...
