For the longest distance runner, that tired feeling may not be due to central fatigue

ntly altered by the ultramarathon with the exception of the sole of the foot, which showed a slightly higher M-wave amplitude after the running.

Conclusions

From these results, it can be concluded that 65 km of running 1) severely depressed the maximal voluntary force capacity mainly because of a decrease in maximal voluntary activation, 2) strengthened the twitch mechanical response, and 3) did not change significantly the M-wave characteristics.

The large loss in maximal voluntary contractions induced by the 65 km (40 mile) ultramarathon was mostly due to central fatigue. On the other hand, the strengthening twitch mechanical responses and M-wave amplitude characteristics were not altered by the extended run.

With few exceptions, neurophysiological and mechanical modifications in PF and KE were comparable. This leads the researchers to believe that, in an ultramarathon, fatigue is task dependent, and has very specific effects on neuromuscular properties compared with a shorter duration of fatiguing exercise.
