Effects of active and passive warm-upon oral temperature and cardiovascular responses in healthy subjects


Annie Sunil George, B Sujatha

Background: Exercise involves an increase in temperature and metabolic process in cells, there is a 13% increase in metabolic rate as each degree increases. The heart rate and blood pressure responses during exercise are measures of stress on the cardiovascular system. Objective: To find the efficacy of oral temperature and cardiovascular responses to active and passive warm – up in healthy subjects. Methodology: An observational study design set up in Meenakshi College of Physiotherapy- Fourty, both male and females were selected by Simple Random sampling. Procedure: Subjects were asked to ride an unloaded lower extremity bicycle ergometer set at a speed of 60meters/second for 15 minutes. Pre & Post warm- up oral temperature and cardiovascular parameters were recorded. Passive warm- up was done using infrared light to the lumbar area for 15 minutes. Post warm-up readings were recorded. The interval between the two warm-ups were kept at a one week interval. Results: The standard mean of systolic blood pressure for active warm-up is 6.918 which is higher when compared to the passive warm-up of 3.277. The standard error for active warm-up is 0.5932 which is lower when compared to passive warm-up which is 0.6815. This shows that active warm-up causes a greater rise in systolic blood pressure when compared to passive warm-up. By using independent t- test there is a high significant difference between active and passive warm-up at 0.05 level of significance. The standard mean for diastolic blood pressure for active warm-up is 5.4054 which is higher when compared to the passive warm-up mean of 2.222. The standard error of active warm-up is 0.5527 which is lower when compared to standard error of passive warm-up which is 0.2848. There is a high significant difference between active and passive warm-up at 0.05 level of significance. The standard mean for heart rate in active warm-up is 4.4595 when compared to the passive warm-up mean which is 2.083. The standard error for active warm-up is 0.2499 which is lower when compared to standard error of passive warm-up which is 0.4389. This shows that active warm-up causes a greater rise in heart rate. By using independent sample t- test, it shows a p value of 0.05 level of significance. The standard mean of oral temperature for active warm-up is 9.3243 which is higher when compared to the passive warm-up mean of 7.22. The standard error of active warm-up is 0.2 499 when compared to the standard error of passive warm-up which is 0.4389. There is a p value of 0.05 level of significance which indicates that both groups cause only a slight rise in body temperature. Conclusion: The study shows that active warm-up causes a significant increase in cardiovascular parameters while passive warm-up did not. This suggests the need for caution when active warm-up is included in treatment program of patients with cardiovascular problems.
