What occurs during the inhalation phase of the breathing cycle?

During the inhalation phase of the breathing cycle, the diaphragm plays a critical role. When the diaphragm lowers, which means it contracts and moves downward, it creates a larger volume within the thoracic cavity. This increase in volume generates a negative pressure that allows air to flow into the lungs. As a result, air is drawn in from the atmosphere, leading to lung expansion.

This process is fundamental to efficient breathing and plays a significant role in stabilizing the core and facilitating optimal movement patterns in Pilates. The expansion of the lungs during inhalation is a preparatory phase that is essential for engaging the deeper stabilizing muscles of the abdomen and back. Understanding how the diaphragm functions during this phase is crucial for both teaching and practicing Pilates effectively.
