WebbFast twitch IIa fibres are ‘white fibres’ as they are less reliant on oxygen supplied by the blood for energy and therefore fatigue faster than slow twitch fibres. Fast twitch type IIa fibres are suited to speed, strength and power type activities, such as moderately heavy weight training (8-12 reps) and fast running events such as the 400metres. WebbMorphometry and oxidative capacity of slow-twitch (type I) and fast-twitch (type IIa and IIb) muscle fibers obtained from vastus lateralis needle biopsies were compared between younger (21-30 yr) and older (51-62 yr) normal fit (maximal O2 uptake = 47.0 vs. 32.3 ml.kg-1.min-1) and endurance-trained …
