PurposeRespiratory muscle strength is measured as a maximal inspiratory pressure (PI max) and maximal expiratory pressure (PE max). The purpose of this investigation is to obtain normal maximal inspiratory and expiratory pressure with respect to age, sex, height, weight and BMI in Indian population.
SubjectsIn this cross sectional study 250 subjects with age from 20 to 70 years were recruited with convenient sampling. They are divided in to five groups i.e. 20-30, 30-40, 40-50, 50-60 and 60- 70. Each group had 50 subjects (males-25 and females-25).
MethodsFor measurement of PE max the subject will inhale to near total lung capacity (TLC) and then exhale as hard as possible and for PI max the subjects exhales to near residual volume (RV) and then give a maximal inhalation effort. Three measurements were taken for each subjects and the best one was included for analysis.
ResultsThe mean value for PI max in male is (75 ± 20 cm H2O) and for PE max is (93± 33 cm H2O) and PI max in female is (48 ± 16 cm H2O) and for PE max is (60 ± 20 cm H2O).
ConclusionData obtained from this study will be useful as simple, reproducible, rapid assessment and interpretation of respiratory muscle function as well as treatment planning.

Background: Cardiovascular disease (CVD) is the leading cause of death and disability worldwide. Cardiac rehabilitation (CR) is important in improving cardiovascular fitness. Estimating physical activity (PA) levels and Energy Expenditure(EE) in Phase-I CR using Accelerometer can help in understanding cardiovascular fitness better.
Method and Materials: PA of 16 participants post Coronary Artery Bypass Graft (CABG) and Percutaneous Transluminal Coronary Angioplasty (PTCA) in Phase-I CR was measured using Actigraph accelerometer. Metabolic Equivalents (METs) and average of daily EE(in Kcals) and steps taken were calculated. Correlation of the Six minute walk distance (6MWD) on the day of discharge and PA levels measured by Actigraphaccelerometer was done.
Results: PA energy expenditure averaged 283.71 Kcals/3days, step counts/day 4861.50, METs 5.79 and the EE in light and moderate intensity activities were 1.01 Kcals and 5.72 Kcals respectively. The time spent in these activities were 62.25 minutes in light intensity and 2 minutes in moderate intensity activities.
Conclusion: PA measured by Actigraph accelerometer was of low to moderate levels in Phase-I CR. There was a weak correlation between PA levels measured by Actigraph accelerometer and 6MWD achieved at the time of discharge.
