Final answer:
The two forms of resistance that we encounter in yoga poses are Tension and Compression, related to the body's physical limits during poses. This is different from airway resistance in the lungs, which affects breathing and gas flow, influenced by lung compliance and the presence of pulmonary surfactant. The two forms of resistance encountered in yoga poses are A) Tension and Compression.
Step-by-step explanation:
The two forms of resistance encountered in yoga poses are A) Tension and Compression. These resistances are present due to physical limitations of the body. For instance, in a pose, the muscles and connective tissues can provide tension, while the compression occurs when parts of the body press against each other, or when the body is compressed due to the pose itself.
It's important to distinguish this type of resistance from variations in airway resistance in the lungs during respiration, which can affect gas flow and breathing. As resistance is created by inelastic surfaces and the diameter of the airways, any increase can mean more difficulty in breathing, as seen in conditions like asthma. Conversely, the presence of pulmonary surfactant and lung compliance can reduce resistance and facilitate easier gas flow.
