The purpose of this study was to know the effect of 4 weeks of pranayama on reaction time (auditory and visual), agility and the cardiorespiratory functions viz. heart rate (HR), respiratory rate (RR), systolic blood pressure (SBP), diastolic blood pressure (DBP), rate pressure product (RPP), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), peak expiratory flow rate (PEFR) and two minute step test (2MST) in community dwelling elderly. After obtaining Institutional Ethics Committee and written informed consent, 38 healthy community-dwelling individuals above 60 years of age were recruited in the study. The individuals performing pranayama on a daily basis were excluded from this study as well as those with a history of any recent hospitalization, acute illness, visual or auditory impairments or with clinical diagnosed case of neurological disorders, musculoskeletal or cardiorespiratory disorders, impaired cognition that made them unable to perform the proposed functional tests. They were assessed for reaction time, agility and cardiorespiratory parameters before the intervention. The intervention included anulom-vilom, kapalbhati, ujjayi pranayama, shitkari & sheetali pranayama, bhramari and bhastrika pranayama. After a period of 4 weeks, the individuals were reassessed for all parameters. Data was analysed using SPSS 24 software.p value of less than 0.05 was accepted as indicating significant difference between the compared parameters.There was a statistically significant change in HR (p=0.000), SBP (p =0.002), RPP (p =0.000), Respiratory Pressures [MIP (p=0.000), MEP (p=0.002)], PEFR (p=0.000), agility (p=0.007), cardiorespiratory endurance (p=0.000) & Reaction Time (p=0.000). However, RR (p=0.071) and DBP (p=0.057) did not show a statistically significant change post intervention. The study shows that short term practice of pranayama is beneficial in improving reaction time, agility and cardiorespiratory functions in community dwelling elderly.
