trainer (Brandon Payne) places a sandbag below his ribcage in order to overload, and train, his diaphragm.
Let’s break down why this works.
Let’s break down why this works.
In order for respiratory function to be optimal, we need something called a Zone of Apposition.
This means the lowest ribs can stay relatively down upon inhalation, which pushes air into the ribcage and subsequently optimally expands the lungs (image credit @postrestinst).

Deep abs such as the Transverse Abs do eccentrically elongate during this time, but they should remain somewhat “tight” to push the air into the lungs & ribs.
So air will go into the belly to some extent, but it shouldn’t primarily go in the stomach.

This is also why “hands on knees” has been shown to be a more effective recovery position than “hands on head” (Michaelson et. al, 2019).
It creates a Zone of Apposition.

The sandbag also has the benefit of creating additional
load pressures into the ribcage, which force the diaphragm to work harder (Chen et. al). This:
Uptake of air into the aveoli, which transfer oxygen to the bloodstream
Contraction of deep ab muscles for exhalation



Fregonezi 2009 compared a loaded breathing group to a non-loaded group and found the loaded group had considerably
:
- Peak airway pressure
- Maximum continuous ventilation
- Peak inhalation airway flow
- Maximum sustained power of inhalation

- Maximum sustained power of inhalation
The article also claims Curry could drop his heart rate below 80 during even just a single 90-second timeout.
This is because the
ability for his breathing volume & control allows him to quickly facilitate his parasympathetic (rest & digest) nervous system which

This is because the


Overall, it is probably fair to say that the current research indicates that resisted sandbag breathing can improve:
- Recovery
- Breathing pattern control
- Nervous system control
- Oxygen delivery to tissues under fatigue
However, we can’t forget an adequate conditioning

This is a complementary intervention that has value but should not be taken as a magic pill in isolation.
Breathing matters and can improve performance. I’m happy this article shed light on that.
