Document Summary
Must have flexibility to figure skate, balance. As intensity increases, increase in kerb cycle enzymes, etc substrates that all translate into more atp aerobically. As intensity increased duration increases- the harder you work the sooner you"ll be tired. Have increased intensity and response in mitochondrial content. Mitochondria is where aerobic metabolism occurs- all substrates and enzymes associates with aerobic metabolism have increased. No change at light to moderate intensity exercise. If you don"t recruit the fibre, they wont adapt. Have to be above lactate threshold before recruiting type ii fibres. After lactic threshold, recruitment of type 2 fibres increases quickly. Slow twitch fibres recruited first, high oxidative. The adaptation plateaus once you get above the lactate threshold. Even as you continue to increase the intensity, don"t see continues change of slow twitch fibres fast twitch fibres is where adaptation begins in high intensities of exercise graph: Part of same study. on this graph more specific intensities being performed.
