Why the study?
The study was conducted to compare the accuracy of available prediction equations and consider the implications of using them to interpret measured Maximal Inspiratory Pressure in healthy older adults.
Do current predictive equations accurately estimate maximal inspiratory pressure in healthy older Caucasian adults?
Do current predictive equations accurately estimate maximal inspiratory pressure in healthy older Caucasian adults?
Current predictive equations for maximal inspiratory pressure are insufficiently accurate for healthy older adults, highlighting the need for multidimensional assessments rather than relying on single reference values.

Caution advised interpreting MIP via prediction equations in older adults; leaves open need for validated, standardized equations.
The objective was to compare the accuracy of available prediction equations and consider the implications of using these equations in interpreting measured Maximal Inspiratory Pressure (MIP) in healthy Caucasian older adults ( n = 129; 65–85 years). Eight studies out of 174 manuscripts were analysed, and predictive equations were extracted. Results show that predicted MIP is variable compared to measured MIP, demonstrating significant between-equation differences. Our analyses suggest that using age, sex, and height to predict ‘normal’ MIP values is insufficiently accurate. Hence, a multidimensional assessment of outcomes will enhance the periodisation and personalisation of rehabilitative and training programs associated with inspiratory muscles, such as inspiratory muscle training.
