True or False: It is important to hold your breath when doing a last rep in any sport to maximize power? please I need some help

In my opinion, it could be considered true, but it has a lack of information in the statement, it would be considered incomplete, that is why as a final conclusion it is considered FALSE.

It is important because by tolerating the breath and inhaling deeply there is no energetic waste in the breath.

In addition, after a high-power exercise, the recovery and hyperventilation stage is completed by intense physical activity where active rest is advised by some professionals.

Explanation:

In addition, the fact of tolerating breathing in a powerful physical activity causes the total energy in that activity to be exhausted, therefore all the energy currency of ATP is destined to the contraction of the skeletal muscle in charge of locomotion.

On the other hand, when performing this activity, it is considered that it is an intense anaerobic activity, therefore the accumulations of lactic acid in the tissue will be greater than those that train long-lasting actions and little demand, with little powerful contraction.

when you rub, you also apply pressure, that pressure can urge the poop to come out. i think that when your rubbing, you also might be slightly breaking it up and that can further fill the stomach.
