rate the importance of the fiber types from most important, to least important for the marathon runners?
ANSWER: For a marathon runner the most important type of muscle fibre on must possess is TYPE 1 or SLOW TWITCH MUSCLE FIBRE, because these fibres helps the person to run a long distance without getting fatigue easily (low fatigue rate). Next to this Type 2A fibres can help to certain extent. Type 2A fibres are oxidative type of fast twitch fibres which helps in moderate distances and intensity. Type 2B fibres or glycolytic type of fast twitch fibres do not help in marathon runners as they are helpful in only short distances due to its high fatigability. Hence,
TYPE 1 FIBRES. > TYPE 2A FIBRES. > TYPE 2B FIBRES. (MARATHON RUNNERS).
