Publication Association of Ambient Air Quality with Male’s Pulmonary Function in Kolkata City, India(Kathmandu University, 2015) Chatterjee, P; Das, PABSTRACT Background Kolkata is one of the polluted metropolitan cities in India where health effects of air pollution are raising serious concern. Objectives Purpose of the present study was to analyze association between levels of air pollutants and pulmonary function of adult males living in two different air pollutant zones of Kolkata. Methods Air pollution data of two ambient air quality monitoring stations located at Rabindrabharati and Victoria Memorial was collected from West Bengal Pollution Control Board, Kolkata for the period from January to March 2012. Study was conducted on 200 males (17-22 yrs), subdivided into two groups from living within 3 km radius of that two monitoring stations. They were investigated for their spirometric lung functions following method and technique recommended by American Thoracic Society. Results were expressed as mean ± SD and independent samples T test was conducted to compare between groups. Results PM10, SO2 concentrations were significantly higher in Rabindrabharati zone, whereas no significant differences were noted in NO2 and CO concentrations though values were higher at Rabindrabharati than Victoria Memorial. FVC, FEV1, FEF25-75%, MVV were significantly lower in males of Rabindrabharati zone. Conclusion Exposure to high air pollutant concentration might be associated with reduced pulmonary function in adult males. KEY WORDS Air pollution, FVC, FEV1, FEF25-75%, MVVPublication Energy expenditure in women boxing(Kathmandu University, 2006) Chatterjee, P; Banerjee, AK; Majumdar, P; Chatterjee, PObjectives: Women boxing have got recognition recently and so far no work has been reported on energy expenditure of national women boxers in India. This study was aimed to estimate the energy expenditure in Indian female boxers during sparring. Methods: A total of 20 female boxers were subjected. Energy expenditure was estimated using the same individual’s HR-VO 2 regression equation. Heart rate was recorded through radiotelemetry. Results: Results reveal that average and maximum energy expenditure considering the total duration of boxing are12.7 +/- 1.3 and 14.4 +/- 1.6 kcal/min. Conclusions: It is concluded that depending on the severity of energy expenditure female boxing comes under heavy category and as it is a pioneer attempt in India, further studies in this aspect are really required which will guide the coaches regarding the energy expenditure pattern in women boxing. Key words: Female boxing, Combat sports, India, Energy costPublication Validity of 20 meter multi stage shuttle run test for prediction of maximum oxygen uptake in Indian female university students(Kathmandu University, 2008) Chatterjee, P; Banerjee, AK; Das, P; Debnath, P; Chatterjee, PAbstract Background: The 20-meter multi stage shuttle run test (20-m MST) has not yet been used by Indian scientists and validity of the test has not been studied for use with any of the Indian population. Aims: The purpose of this study was to validate the applicability of the 20-m MST in Indian adult female. Materials and methods: For application of direct method cross over design was followed. For validity of the results repeatability was used. Methods and Material: 32 female university students (age range 20.4 ~24.8 years) from three different universities of West Bengal, India were recruited for the study. Direct estimation of VO2 max comprised treadmill exercise followed by expired gas analysis by scholander micro-gas analyzer whereas VO2 max was indirectly predicted by the 20-m MST. Statistical Analysis: Paired t-test, Pearson’s product moment correlation, linear regression statistics and Bland and Altman approach for limit of agreement were adopted for statistical analysis of the data. Results: The difference between the mean (SD) VO2 max values of direct measurement (VO2 max = 32.84 ± 2.92 ml/ kg/min) and the 20-m MST (SPVO2 max = 32.60 ± 3.40 ml/kg/min) was statistically insignificant (p>0.10). Limits of agreement analysis also suggest that the 20-m MST can be applied for use with the studied population. Conclusions: The results suggest that the application of the present form of the 20-m MST be justified in the studied population. For better prediction of VO2 max a new equation has been computed based on present data for use with Indian female university students. Key words: VO2 max, Cardiovascular fitness, Sedentary, Female.
