Document Summary

Morphology: measurement of muscle size and the change over time, it"s the only way to directly measure muscle, other tools, ct scans, mri, ultrasound. Can measure the structural components (cross sectional area of individual muscles, but not individual muscle fibre type: near infra-red spectroscopy (nir) to measure the oxygenation of the muscle. How much oxygen was sucked up to the muscle. The greater the extraction the greater the difference: devices (isokinetic dynamometers) and tests (vertical jump tests) can be used to for measurement of neuromuscular performance (output, *can create the most force with isometric movements) Type iib, type iix fibre types: sprinters (any athletes needing anaerobic system, 2) fast fatigue resistance (ffr) Type iia muscle fibre: 3) slow (s) Most aerobic muscles, may include some ffr. Gross movements: they have high muscle fibres: nerve ration. Low muscle fibre: nerve ratio: eye, the muscle fibres of different mu"s can also vary throughout the whole muscle.
