| description | Introduction: Aerobic exercises which are isotonic in nature
have been proved to be beneficial in a number of cardiovascular
and lifestyle diseases. But the effect of isometric exercises on
cardiovascular and respiratory system is not fully evaluated.
Existing literature on effect of isometric exercise on respiratory
flow parameters are scanty and needs to be studied. Further,
the impact of muscle mass on respiratory flow parameters need
to be evaluated.
Aim: To investigate the change in respiratory flow parameters
(Peak Inspiratory Flow (PIF), Maximal Inspiratory Flow (MIF) 50,
Peak Expiratory Flow (PEF), Maximum Expiratory Flow (MEF)
25-75, MEF 25, MEF 50 and MEF 75) in response to Sustained
hand grip exercise and to find out any correlation between these
flow parameters and Fat Free Mass Index (FFMI).
Materials and Methods: A cross-sectional study was conducted
at Department of Physiology, MKCG Medical College, Berhampur
University, Odisha between October 2011 and August 2014. A
total of 150 healthy volunteers aged between 17 to 25 years
were included in the study. Anthropometric measurements were
recorded using standardised instruments. Body fat percentage
was measured by Bioelectric Impedance Analysis technique
and then Fat Free Mass (FFM) and FFMI were calculated using
standard formulae. Respiratory Flow parameters were assessed
using Flow handy Spirometer as per the American Thoracic
Society/European Respiratory Society (ATS/ERS) guidelines.
Sustained hand grip exercise was performed with Physilab Grip
Dynamometer. IBM SPSS Statistics Version 24.0, was used for
statistical analysis. Paired sample t-test was used to compare
lung volumes at baseline and after 3 minutes of sustained hand
grip exercise. The p-value <0.05 was considered statistically
significant. Karl Pearson Correlation coefficient was used
to study the linear relationship between FFMI and various
inspiratory and expiratory flow rates.
Results: The mean values of all respiratory flow parameters
under study decreased at 3 minutes of sustained hand grip
exercise as compared to baseline values. This change was
statistically significant for PEF (p-value 0.012), MEF 25-75
(p-value 0.041), MEF 50 (p-value 0.001), MEF 75 (p-value 0.012)
and MIF50 (p-value 0.004) (p<0.05). All the flow rates studied
except MEF 25 showed significant positive correlation with
FFMI (r-values between 0.231 to 0.380, p<0.05) but the strength
of association was low.
Conclusion: There was a statistically significant reduction in
both inspiratory and expiratory flow parameters with isometric
sustained hand grip exercise. So, isometric exercises should be
avoided in patients with obstructive airway diseases. But muscle
mass should be improved for better ventilation as authors
observed a positive correlation between FFMI and respiratory flow rates. |
