Endurance time in slow and fast contracting muscle groups

Biochemical comparison of fast- and slow-contracting squid muscle.

The myofilament protein compositions of muscle fibres from the transverse muscle mass of the tentacles and the transverse muscle mass of the arms of the loliginid squid Sepioteuthis lessoniana were compared. These two muscle masses are distinct types, differing in their ultrastructural and behavioural properties. The transverse muscle of the tentacles consists of specialized muscle fibres that ...

The Effect of Intensive Endurance Activity on Myocyte Enhancer Factor 2C Gene Expression of Slow and Fast Twitch Muscles in Male Wistar Rats: An Experimental Study

Background and Objectives: Myocyte enhancer factor 2c activates the genes of the slow-twitch muscle, the muscle which plays role in endurance activity. Therefore, the aim of this study was to evaluate the effect of a program of intensive endurance activity on MEF2c gene expression in fast and slow twitch skeletal muscles in wistar rats. Materials and Methods: In this experimental study, 14 mal...

the effect of endurance training on amount of nicotinic acetylcholine receptors (nachr) in fast and slow twitch muscle of male wistar rats

background: the purpose of the present study was to investigate the effect of endurance training on amount of nicotinic acetylcholine receptors (nachr) in fast and slow twitch muscles of male wistar rats. methods: a number of 15 male wistar rats randomly divided into two groups of control (n=7) and endurance training (n=8). the endurance training treadmill running (for 12 consecutive week, 5 da...

Difference between Myosin Light and Heavy Chain Isoforms Patterns in Fast- and Slow-twitch Skeletal Muscle: Effect of Endurance Training

Slow and Fast Responses in Cockroach Leg Muscle

INTRODUCTION The multiple innervation of arthropod muscle has led to the suggestion that much of its electrical and mechanical activity is local in nature. It has also been shown by stimulation of isolated motor axons that several neuro-muscular systems may exist in the same crustacean muscle. Rapidly contracting fast systems, slow facilitating systems, and inhibitory mechanisms have been descr...
