ABSTRACT
This study assessed the effects of aerobic training on pulmonary functions of asthmatic adults in Kaduna State College of Education, Gidan waya, Nigeria. For the purpose of this study, one group repeated trials research design, in which the subjects were given different treatments at different times were used, In this design, subjects underwent aerobic training of 40 - 50 % maximal heart rate(RPE ) for a 20 to 25 minutes in the training session conducted in three (3) alternate days per week for twelve (12) weeks. A total of 30 asthmatic adults attending the college clinic at the Respiratory Unit volunteered to participate in this study. Out of the 30, 26 met the inclusion criteria and were assigned to the aerobic training; since there was no control group and the baseline values served as the control. The aerobic group engaged in treadmill walk at intensities ranging between 40% - 50% of estimated HR max. The training given was at a moderate intensity of 40 -50 % maximal heart rate (MHR) ( 1- 4 weeks ) which was increased progressively from 51 - 60 % HRMax(5 - 8 weeks ) and 61 - 70 % HRMax ( 9 - 12 weeks ). The data collected were statistically analyzed using repeated measures analysis of variance using a level of significance of 0.05. The result of the study revealed that aerobic training programs caused an increase P < 0.05 in FEVI, FIVI, VC, VO2 max, FEV/ FVC ratio and RR. It was concluded that asthmatic adults should participate in aerobic exercise regularly in order to control their asthma attacks( episodes ). Health professionals and fitness centers should use this method of training for asthmatic patients and should be encouraged to exercise themselves at least 20 - 40 minutes in a week to improve their pulmonary functions.
