Abstract :

<p>&nbsp;</p> <p class="MsoBodyText" style="margin-bottom:0in;margin-bottom:.0001pt;text-align:&#10;justify;line-height:200%"><span style="font-size:12.0pt;line-height:200%;&#10;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">Present study was carried out with an objective to find out effects of exercise on aerobic capacity and lipid profile of school-going trained boys in environments differing in air pollution level but with similar climatic characteristics. 40 youngster footballers (14-16 years) of West Bengal volunteered for this study. Two places with similar climatic conditions, but low and high levels of air pollutants were selected. </span><span style="font-size:12.0pt;line-height:200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;;&#10;mso-fareast-font-family:&quot;Times New Roman&quot;">Height, weight were measured. </span><span style="font-size:12.0pt;line-height:200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">Shuttle run test was conducted for assessment of VO_2max in both areas after a one week gap in both zones. </span><span style="font-size:12.0pt;line-height:&#10;200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;;mso-fareast-font-family:&quot;Times New Roman&quot;">Immediately after completion of shuttle run test, venous blood sample was drawn from cubital vein and </span><span style="font-size:12.0pt;line-height:200%;&#10;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">Cholesterol, Triglycerides, HDL-Cholesterol, LDL-Cholesterol, Cholesterol/HDL-Cholesterol ratio</span><span style="font-size:12.0pt;line-height:200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;;&#10;mso-fareast-font-family:&quot;Times New Roman&quot;"> were estimated by standard methods. </span><span style="font-size:12.0pt;line-height:200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">Measured parameters were compared between two areas. A significant decrease in mean VO_2max, HDL-Cholesterol, as well as significant increase in Cholesterol, Triglycerides, LDL-Cholesterol, Cholesterol/HDL-Cholesterol ratio was observed in higher-polluted than in lower-polluted area. Exercise in high-polluted air may affect sports performance level adversely causing a less favourable lipid profile and reduction in aerobic capacity in trained school-going boys.<i style="mso-bidi-font-style:normal"> </i><o:p></o:p></span></p>
