Functional benefits of respiratory muscle training
Figure 4.1 Interrelationship of the three key properties of inspiratory muscles: pressure (strength), flow (velocity) and power (strength × velocity). Squares = pressure / flow; circles = pressure / power. (Adapted from McConnell AK, 2011. Breathe strong, perform better. Human…
Implementing respiratory muscle training
4. Some specific physiological indicators of potential load / capacity imbalance of the respiratory muscles, and / or inadequate respiratory muscle function. The following are not unique to load / capacity imbalance of the respiratory muscles, but…
