Background: Abdominal muscles are the major expiratory muscle and play an important role in ventilation. The purpose of this study is to examine the effects of respiratory muscles training with non-respiratory maneuver such as abdominal muscle training exercise on pulmonary functions in females. Objective: 1) To determine the effects of sit up exercise for 6 weeks on pulmonary functions in females. 2) To determine appropriate training intensity by comparing effects of sit up exercise for 6 weeks on pulmonary functions in females at different intensities. Methods: In this Experimental study 60 Subjects were randomly assigned to low (n=20), moderate (n=20), and high intensity (n=20) groups and they performed sit-up exercises 4 days a week for 6 weeks. The intensity for each group was set at 40% (low), 60% (moderate) and 80% (high) respectively as per the numbers of sit-ups they performed during 1-min sit-up test. Baseline and post-training measurements included pulmonary functions (Maximal Voluntary Ventilation, Forced Vital Capacity), Peak Expiratory Flow Rate and 1-minute sit-up test. Results: Significant differences were found in post-training pulmonary functions among the 3 groups. Maximal Voluntary Ventilation after training was found significantly high (p<0.05) in all 3 groups. Forced Vital Capacity & Peak Expiratory Flow Rate was significantly increased (p<0.05) in High group as compared to Low group but not significantly high as compared to moderate group. Conclusion: The non respiratory maneuver such as abdominal muscle training at moderate to high intensity not only improves abdominal muscle strength & endurance but also enhance the pulmonary functions through respiratory muscle training.
