RESUMO
Background: Music has been used in exercise classes for many decades. The role of music in increasing the exercise performance is well recognized but there is very little information about effect of music on post-exercise recovery time. Methods: The present study was conducted to see the effect of musical sounds on post-exercise recovery time following moderate exercise with Harvard step test in young healthy volunteers. 30 young healthy volunteers (17 males, 13 females) aged between 17 to 20 years were recruited for the study. Pulse rate, systolic BP, diastolic BP were recorded prior to exercise in lying down position. The participants were subjected to moderate exercise by Harvard step test for 3 minutes on 3 consecutive days. They were allowed to rest in silence on 1st day, rest with hearing slow music on 2nd day and rest with hearing fast music on 3rd day. During the post-exercise relaxation time PR, SBP and DBP were measured immediately and after every 1 min. until the parameters returned to resting values. Data was statistically analysed using ANOVA test and 0.05 level of significance was set prior to the study. Results: The result showed that with slow music, recovery time of pulse rate (5.2 ± 2.1), systolic blood pressure (3.9 ± 1.1) and diastolic blood pressure (3.2 ± 1.7) were significantly faster as compared to both no music and fast music. Conclusion: The study concluded that music hastens post-exercise recovery and slow music has greater relaxation effect than fast or no music.
RESUMO
Background: Yoga makes the mind calm & relaxed, strengthens & tunes the body, brings them into harmony with each other. Pranayama have been shown to reduce the resting respiratory rate, further they increase the vital capacity, timed vital capacity, Maximum voluntary ventilation, Breath holding time, Maximum expiratory pressure. Savitri pranayama is one of the unique pranayama techniques which involves slow, rhythmic, and deep breathing. This pranayama has an added advantage that it is effective even if it is done in lying down position .So it can be practiced by non-ambulatory patients too. Aims & Objective: To compare changes in respiratory parameters in the subjects practicing Savitri Pranayama and with that of subjects not practicing any type of Pranayama. Material and Methods: New entrants in yoga class of shivanand ashram, Ahmedabad were selected as subjects for this study & compared with control group- not performing any type of exercise or yoga. The test group were trained by a qualified instructor & then practiced savitri pranayama for 6 days in a week for 12 weeks. Peak Expiratory Flow Rate, Maximum Breathing Capacity, Expiratory pressure,40mm endurance test, Breath holding time were recorded twice in test group - before starting pranayama & after 12 weeks. Readings of control group were taken in both phases too. Results: First phase recording showed no significant differences in any of the tested parameters between Test and Control groups. Second phase recordings showed significant differences in all the tested parameters between Test and Control groups. Conclusion: In the test group there is statistically significant increase in PEFR, MBC, EP, 40mm endurance test & BHT. So it is concluded that a practice of Savitri Pranayama has beneficial respiratory effects. This pranayam can be practiced by bedridden & physically handicap persons. It has psychological effect for relaxing the patients so can be practiced for mental well-being.
