title: Maximum inspiratory and expiratory pressures have no daytime variation in healthy men.
abstract: The variation of maximal respiratory pressures (Pimax and Pemax) in healthy subjects were studied on the same day in 16 non-smoking healthy men (age 26.2 +/- 3.2 years). The Pimax and Pemax were obtained on three occasions (8 a.m., 2 p.m. and 9 p.m.) within the same day. There were no differences between readings for Pimax and Pemax values.
