Maximal oxygen consumption in asthma patients before and after aerobic training program

ABSTRACT: The objective of present study was to assess whether cardiovascular fitness was affect with aerobic exercise program in asthma patients. Twenty two inactive males with asthma were randomly assigned into exercise and control groups. Subjects of exercise group were participated in aerobic training for 3 times per weeks at 60-80 % of maximal heart rate. Control subjects were instructed to maintain their habitual activities. Pre and post training values of cardiorespiratory fitness (VO2max) was calculated by a stationary cycle ergometer. Student’s paired‘t ’ test was applied to compare the pre and post training outcome. A p-value of less than 0.05 was considered to be statistically significant. There were no statistically significant differences between the exercise and control subjects with regard to the anthropometrical markers or VO2max (P> 0.05). Compared to pre-training, VO2max increased significantly (p = 0.001) after exercise program in exercise group but was not changed in control subjects. All anthropometrical markers decreased significantly by exercise program (p < 0.05). A long-term aerobic exercise intervention can induce favorable changes in cardiorespiratory fitness in adult males with mild to moderate asthma.
