Hi Marcelo,

There is many reports out there. Here are some recent papers:

Age-Related Changes in Dynamic Postural Control and Attentional Demands are Minimally Affected by Local Muscle Fatigue http://www.ncbi.nlm.nih.gov/pubmed/26834626

Acute effects of muscle fatigue on anticipatory and reactive postural control in older individuals: a systematic review of the evidence http://www.ncbi.nlm.nih.gov/pubmed/24978932

Biomechanical reorganisation of stepping initiation during acute dorsiflexor fatigue http://www.ncbi.nlm.nih.gov/pubmed/21605984

Impact of ankle muscle fatigue and recovery on the anticipatory postural adjustments to externally initiated perturbations in dynamic postural control http://www.ncbi.nlm.nih.gov/pubmed/23111432

Those a few recent studies, and you can go from there to access many more.

Hope this helps. Norbert
