Objective:
To associate different methods of measuring maximum phonation time (MPT) according to sex and body mass index (BMI).
Methods:
The study included 30 men and 30 women aged between 18 and 45years. Four different methods of measuring MPT were tested, and the obtained values were compared between sexes and BMI.
Results:
There was no statistically significant difference between the different methods of measuring MPT. Comparisons between sexes showed significant differences between men and women. Regarding BMI, overweight subjects had higher MPT values than eutrophic subjects.
Conclusion:
No differences were found between the possible methods of measuring MPT. Men had higher MPT values than women, and overweight subjects also obtained higher MPT values.
