“…Neurophysiologically, skeletal muscles are dynamic and able to change their metabolism based on environmental demands, being amount of activity or inactivity, hormonal status, loading or lack of loading. With the right training, the muscle mass or even the metabolism and ratio of fast twitch fibres (powerful but easily fatigued) to slow twitch fibres (less powerful but fatigue resistant) may be altered [77,78]. Changes in musculature have been linked to craniofacial development, it has even been said that assessing intraoral pressure may be an important tool for studying the development of malocclusions [79].…”
