Summary

The mechanisms contributing to muscle fatigue in extreme long-duration exercise bouts are poorly understood. Ultra-endurance exercise is an excellent model for the study of adaptive responses to extreme loads and stress and it is an especially useful model for documenting the origins of central fatigue. This protocol will compare fatigue during and after ultra-endurance exercise bouts that result in moderate lower-limb tissue damage (i.e. cycling) or significant damage (i.e. running). The results of this protocol will allow us to further understanding of the reasons for major central fatigue, i.e. within the central nervous system, in ultra-endurance.
