Accuracy of equations for calculating normal values of maximal inspiratory mouth pressure in older men and women
摘要
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.
