Abstract
The aim of this study was to verify the influence of the effect of Ventolin Inhaler N on endurance performance in athletes without asthma diagnosis. The sample included a performance runners - men ( n = 16 , age 25.94 +- 3.54 years , height 183.09 +- 5.05 cm , weight 79.29 +- 7.88 kg ).
We investigated the effect of resting spirometric parameters (FVC, FEV1) and spiroergometry test submaximum and maximum load (oxygen uptake, ventilation, RER, heart rate, speed at the anaerobic threshold and maximum speed achieved) on the treadmill. For design research, we used a plan with cross-classification and repeating the measurement.
To evaluate the statistical significance of differences, we used paired t - test for two dependent files. Statistical significance was evaluated on level 0.05 respectively 0.01.
For data processing software was used SPSS PASW Statistics 18. The study showed that Ventolin Inhaler N has a statistically significant effect on performance in athletes without a diagnosis of asthma in both resting spirometry measured before the test (FEV1, p = 0.001; FVC, p = 0.026) and after test (FEV1 p = 0.020).
In submaximal load (speed 13km.h-1), we found significant differences in parameter of oxygen uptake (p = 0.005) ventilation (p = 0.009) and respiratory quotient (p = 0.015). In the area of maximum load, we found significant differences in parameter of oxygen uptake (p = 0.009), ventilation (p = 0.0015) and respiratory quotient (p = 0.001).
We have also demonstrated an increase in speed at the individual anaerobic threshold (p = 0.005). The negative effects are statistically significant difference found only in the incidence of cramps (p = 0.043).
