Does ventilation increase with exercise? - ️️Fitness doesn't increase ventilation Type 1 Muscle Fibres - ️️Slow contraction time, small motor neuron, highly resistant to fatigue, low force production but high mitochondria and capillary density. Type 1 fibres are constantly working underneath and used for aerobic activity. Type 11a Fibres - ️️Moderately fast contraction time, medium motor neuron, medium force production and used for long term anaerobic activity <30min Typ...
