ABSTRACT
Maximal inspiratory pressures (MIP) and maximal expiratory pressures (MEP) are useful indices of respiratory muscle strength in athletes. The aims of this study were to describe the strength of the respiratory muscles of Olympic junior swim team, at baseline and after a standard physical training; and to determine if there is a differential inspiratory and expiratory pressure response to the physical training. A cross-sectional study evaluated 28 international-level swimmers with ages ranging from 15 to 17 years, 19 (61 %) being males. At baseline, MIP was found to be lower in females (P = .001). The mean values reached by males and females were MIP(cmH2O) = M 100.4 (± 26.5)/F 67.8 (± 23.2); MEP (cmH2O) = M 87.4 (± 20.7)/F 73.9 (± 17.3). After the physical training they reached MIP (cmH2O) = M 95.3 (± 30.3)/F 71.8 (± 35.6); MEP (cmH2O) = M 82.8 (± 26.2)/F 70.4 (± 8.3). No differential pressure responses were observed in either males or females. These results suggest that swimmers can sustain the magnitude of the initial maximal pressures. Other studies should be developed to clarify if MIP and MEP could be used as a marker of an athlete's performance.
