RESUMEN
The study examined the intensity of an individual’s physical activity by using self administered International Physical Activity Questionnaire Short Form 7 (IPAQ-SF7) as a measuring tool and assessed its impact on the various body physiological functions likely to alter drug pharmacokinetic processes. The study was conducted in normal, subjects inhabited at different regions in India, with the translated versions of IPAQ-SF7 in Hindi and Tamil languages found the high intensities of vigorous, moderate activities and walking and showed excellent reproducibility as similar as it has been studied in different population worldwide. The resting state systolic and diastolic blood pressures, heart rate and respiratory rate were significantly higher in the subjects. The diaphragmatic breathing pattern was found used by majority of the subjects. The energy utilization of the subjects on their physical activity was obtained in high Metabolic Equivalence of Task (METs) minutes per week. Thus significance in the physiological parameters was strong enough to alter the pharmacokinetics of drugs whose metabolism and elimination are primarily dependent on renal function. This results which will be helpful in optimizing and selecting the drug doses for the people under extreme physical activity with less oxygen consumption in muscles, low level of respiratory rates and high energy utilization in their body.
