Type 2 are fast twitch muscle fibres and are white in colour, fast to contract and fast to fatigue Specificity means that the training you do should match the
Are all muscle fibres the same? No There are 2 different types Fast twitch fibres contract very quickly but they fatigue quickly Slow twitch fibres
relative distribution of fast-twitch and slow-twitch (ST) muscle fiber types and fiber size The ST was not different in the
like cat and rat muscle is composed of two distinct types of fibers, both of which are twitch fibers The two types of fibers can be designated “fast”
the pooled results indicated the presence of at least two types of unit The recorded twitch tensions also varied considerably (from 2 to 14 g) but were not
Table 2 Characteristics of ST, FTa and FTx muscle fibers Characteristics Muscle Fiber Types Slow Twitch Fast Twitch a Fast Twitch x Aerobic (oxidative)
Slow twitch (I) fibers innervated by alpha 2 motor neurons, smaller of the two α motor neurons; Fast twitch (II) fibers innervated by alpha 1 motor neurons,
The oxidative energy system primarily uses carbohydrates and fat as a fuel source Muscle Fiber Types • Fast-twitch muscle fibers have a high anaerobic
From your reading and previous knowledge, What are the characteristics of fast and slow twitch muscle fibres? Brainstorm Slow twitch, Fast twitch 1 2 3 4
There are two basic categories of skeletal muscle – fast twitch (also referred to which type of muscle fibers you have, type 1 (slow) or type 2 (fast)
Fast/slow twitch muscle fibres classified as Type I, IIA, and IIB muscle fibres, predominantly fast twitch myosin isoforms are termed Type II fibres,
2 FAST TWITCH MUSCLE FIBRES - Large in size These fibres contract quickly and powerfully Muscle fibre types Elite endurance athletes possess a high
Motor Unit: a single motor neuron and all of the muscle fibers that it innervates Fast twitch fibers (type II): rely on anaerobic metabolism,
c Tire slowly so used in postural muscles 2 Fast oxidative (Type II A) AKA fast twitch A or fatigue resistant a High mitochondria and myoglobin
