Motek is one of the pioneers in the field of motion capture, with a history of developing new production technology and integrating techniques
from the world of research, medicine and robotics into affordable, broadcast-ready solutions.
Motek has extensive, production grade, motion capture libraries on their site: see http://www.motekentertainment.com/shop/
This package contains a subset of motion capture data as FBX files.
These can be used in the Unity Mecanim system as animation clips.
All FBX files have a Humanoid rig setting and a skeleton mask.
The example scene file shows you all animations after eachother on the dummy.
