Why can't I sprint at Minecraft bedwars (handy)?

Whenever I play Minecraft (pocked edition) games, I can't sprint for a while. I'm always slower than normal. Only when I leave the game will it go again. But then it happens again. And that's really annoying. I hope someone can help me. I've tried everything. Lg of none

Are you hungry? If so, you can't sprint from 3 hunger points.

No, that is also full of hunger but thanks anyway
