Abstract
Background : The rate of smoking among young people has increased steadily over the past decades. Previous research indioated that smokers have lower expiratory muscle strength than non-smokers, thereby affecting lung function. Abdominal muscle training has been shown to improve respiratory muscle strength. Therefore, the abdominal muscles training, as an alternative intervention, could benefit on respiratory muscle and lung function in young smokers.
Objective : To evaluate the effect of abdominal muscle training on expiratory muscle strength and lung function in male early adulthood smoker.
Method : A total of 15 healthy male smokers, aged 18-22 years old, were randomly divided into 2 groups: an experimental group (8 men) and a control groups (7 men). The experimental group performed abdominal muscle training 2 days per week for 8 weeks while the control group received no treatment. All participants completed respiratory muscle strength test, lung function test and abdominal muscle strength test before and after 6-week of training.
Results : After training, the maximum expiratory pressure (MEP) was significantly increased in the experimental group (p = 0.012), but not in control group, when compared to pre-training. Neither the maximum inspiratory pressure (MIP) nor lung function were affected after training in both groups. After training the abdominal muscle strength in the experimental group was significantly increased when compared to before training and control group (p = 0.021).
Conclusion : A 8-week of abdominal muscle training had a small effect on expiratory muscle strength and lung function in college student smokers. Nevertheless, there was a trend for the expiratory muscle strength and abdominal muscle strength to be improved after training compared to control.
