  The Infrared Space Observatory (ISO) was an extremely successful european
space mission that gave us an unparallel view of the Universe in the infrared,
and provided us with hundreds of observations of star forming regions and
bipolar outflows. Three of the instrument teams, in charge of the infrared
camera (CAM) and the two spectrometers at short and long wavelengths (SWS and
LWS respectively), used a significant fraction of their guarantee time to study
YSOs and outflows spectroscopically. In here, I will briefly review some of
their main findings, particularly the detection of water, H2 rotational
emission lines and the presence of other complex molecules. I will present new
spectroscopic results on HH 1-2, HH 7-11 and Cep E, and their sources. And
finally, I will discuss some of the general trends derived from these
observations and their relevance in understanding the emission from these
objects using J and C shock models.
