The present study was carried out with the objective to examine whether environmental air pollutants have any effect on selected physical fitness components of trained and untrained boys, age ranging between 14 and 16 years, of West Bengal, India. The parameters included maximum oxygen uptake (VO2max), agility, leg muscle power and handgrip strength. The sample consisted of 60 footballers (trained boys) (30 from Kolkata and 30 from Sonarpur) and 70 untrained boys (35 from Kolkata and 35 from Sonarpur) of West Bengal. Ambient air quality of the two zones was monitored. Air pollutants` levels were higher in Kolkata than Sonarpur. Standard techniques and procedures were followed for all the physical fitness tests. Results were expressed as mean ± standard deviations. Independent samples T test and general linear model (GLM) univariate procedure were conducted to compare the groups. Results of the study revealed that there was no significant difference in physical parameters of the groups between the zones. But VO2max, agility, leg muscle power, and handgrip strength of footballers (trained boys) in Sonarpur (VO2max = 53.82±4.40ml/kg/min, Agility=9.69±0.16 sec, Leg muscle power=37.37±5.61 cm, Handgrip=33.87±6.15 kg) were significantly higher than Kolkata (VO2max=51.07±5.83ml/kg/min, Agility= 9.95±0.54 sec, Leg muscle power=32.54±5.36 cm, Hand grip=24.15±5.68 kg) (p<0.05, p<0.05, p<0.05, p<0.01 respectively). In the case of the untrained boys, VO2max, agility, leg muscle power, handgrip strength were also significantly higher in the Sonarpur (VO2max =45.23.±4.72 ml/kg/min, Agility=10.01±0.50 sec, Leg muscle power=38.06±5.47 cm, Handgrip=36.97±6.32 kg) region than Kolkata (VO2max = 42.83 ± 4.79 ml/kg/min, Agility= 10.47±0.79 sec, Leg muscle power=32.56±6.4 cm, Handgrip=26.80±6.97 kg) (p<0.05, p<0.05, p<0.01, p<0.01 respectively). Training had no impact on changing the physical fitness components of footballers between the two zones. It was concluded that environmental air pollutants had adverse effects on physical fitness components.

A Regression Equation for the Estimation of Maximum Oxygen Uptake in Indian Male University Students
( Pinaki Chatterjee ),( Alok K. Banerjee ),( Parimal Debnath ),( Paulomi Das ),( Pratima Chatterjee ) 한국스포츠정책과학원(구 한국스포츠개발원) 2008 International Journal of Applied Sports Sciences Vol.20 No.1
The purpose of the study was to validate the applicability of 20-meter multi stage shuttle run test in Indian male university students. 31 Indian male university students (age range 20.42 ~ 24.92 years) from three different universities of West Bengal, India were recruited for the study. Direct estimation of cardiorespiratory endurance (VO2max) comprised treadmill exercise followed by expired gas analysis by scholander micro-gas analyzer whereas VO2max was indirectly predicted by the 20-meter multistage shuttle run test. The difference between the mean (standard deviation) VO2max values of direct measurement (VO2max = 39.60+/-1.86 ml/kg/min) and 20-meter multi stage shuttle run test (SPVO2max = 39.20+/-2.28 ml/kg/min) was statistically insignificant (p = 0.1, confidence level p ≤0.05). Limits of agreement analysis also suggest that the 20-m multistage shuttle run test can be applied for use with the studied population. The results suggest that the application of the present form of 20-meter multistage shuttle run test be justified in the studied population. For better prediction of VO2max a new equation has been developed based on present data for male university students of India.

A Regression Equation to Predict VO2 Max of Young Football Players of Nepal
Pinaki Chatterjee,Alok K. Banerjee,Paulomi Das,Parimal Debnath 체육과학연구원 2009 International Journal of Applied Sports Sciences Vol.21 No.2
The purpose of the study was to validate the applicability of the 20-m Multi Stage Shuttle Run Test (20-m MST) in young football players of Banke district, Nepal. For application of direct method "cross-over design" (random sequencing) was followed. For validity of the results, repeatability was investigated where 22 subjects performed the test (20-m MST) twice. Thirty five young football players (age range 14~16 years, sex- male) from different sports academies of Banke district, Nepal were recruited for the study. Direct estimation of Maximal oxygen consumption (VO2 max) comprised of treadmill exercise followed by expired gas analysis by scholander micro-gas analyzer, whereas VO2 max was indirectly predicted by 20-m MST. The difference between the mean (± standard deviation) VO2 max values of direct measurement (VO2 max=51.68±5.25 ml/kg/min) and the 20-m MST [Shuttle predicted VO2 max (SPVO2 max)=51.36±5.36 ml/kg/min] was statistically insignificant. The results suggest that the application of the present form of 20-m MST may be justified in the studied population. However, to better predict VO2 max, a new equation has been developed based on present data. The new equation is recommended to be used for the studied population.
