Purpose: Increase in demand on the respiratory system leads to recruitment of abdominal muscles [transverses abdominals] as accessory respiratory muscle. This correlation between the muscle strength and the pulmonary function test is studied in this research.
Method: 80 healthy subjects were included in the study. Lumbar core strength, breath holding time (BHT) and components of pulmonary function tests such as Peak Expiratory Flow Rate (PEFR), Tidal Volume (TV) and Maximum voluntary Ventilation (MVV) were assessed using pressure biofeedback unit, stopwatch and RMS-respirator® respectively.
Result: Data analysis revealed a significantly good correlation between PEFR and TA strength(r= 0.51) and fair correlation with endurance(r=0.42). TV showed no correlation with both TA strength (r= 0.0031) and endurance (r= 0.081). MVV showed fair correlation with both TA strength(r=0.41) and endurance(r=0.33) which was statistically significantly. BHT showed a good correlation with TA strength(r= 0.51) and endurance (r=0.65).
Conclusion: Thus the study supports that there is a correlation of TA strength and pulmonary functions in healthy adults except with tidal volume.
