Solution

If the breath is held for the maximum possible time, it results in an intermittent hypoxic condition, characterized by depleted oxygen content in the body.
Once the hold is released, the breathing rate increases so as to make up for the depleted oxygen content and flush out excess carbon-di-oxide.
