ABSTRACT
Background: Chefs exposed to cooking fumes are at risk due to the toxic products that are produced during cooking. Studies have shown that exposure to cooking fumes decreases lung capacities, affects breathing and cause other respiratory diseases. Yoga strengthens the respiratory musculature due to which chest and lungs inflate & deflate to fullest possible extent & muscles are made to work to maximal extent. Pranayama makes efficient use of abdominal & diaphragmatic muscles and improves the respiratory apparatus. Aim: The present study was done to determine the effect of Yoga & Pranayama on chest expansion & breath holding time in chefs exposed to cooking fumes. Methods: In this experimental study 30 chefs exposed to cooking fumes who fulfilled the inclusion and exclusion criteria using Medical research council questionnaire for respiratory symptoms were selected for yoga and pranayama program for 6 weeks, 3 sessions per week for 45 minutes. Pre and post respiratory functions were assessed by measuring chest expansion and breath holding time. Stastical analysis was done by using Wilcoxan test to compare the pre & post chest expansion. Paired t test was used to compare the pre & post breath holding time. Results: There was significant increase in chest expansion and breath holding time compared to pre yoga and pranayama practice. Conclusion: This study showed that there is significant effect of yoga and pranayama on chest expansion & breath holding on chefs.
ABSTRACT
Background: Pregnancy is a state of various physiological and anatomical changes in a female’s body. The increasing body weight leads to the shift in COG and increase in abdominal contents leading to reduced stability and increased use of visual cues which occur in pregnant females as pregnancy advances. Several physiological responses to pregnancy diminish the body’s ability to maintain adequate balance, and place the women at a higher risk of injury and falls. Thus assessment for postural stability is very important to prevent such complications. Objective: To evaluate postural balance in third trimester pregnant females using Four square step test. Materials and methodology: Study was cross sectional observational study. Data was collected by convenient sampling method .60 Healthy women, 30 pregnant and 30 non-pregnant, of age group 20-30 years were selected. Evaluation of postural stability was done using 4 square step test (FSST). The mean of two time trial (in seconds) was noted. The data was collected and analysed using paired t-test. Results: There was statistically significant difference in mean time taken to complete the test between pregnant group and non-pregnant group. (p<0.05) Conclusion: Thus, our study showed that pregnant females took longer time to complete the postural balance test.
