Aerobic anaerobic transition level of indian middle and long distance runners

Aerobic anaerobic transition level of indian middle and long distance runners

Indian Journal of Medical Research 88(OCT): 371-375

A study was carried out on 23 elite Indian runners (12 middle distance and 11 long distance runners) to assess the aerobic-anaerobic threshold level and also to compare them with international counterparts to enable the coaches and sports medicine specialists in using the anaerobic threshold (AT) concept more efficiently as a training tool in endurance events. The cardiorespiratory variables at maximum effort were determined during a graded protocol of running in treadmill, starting from 10 km/h and increasing every 2 min at the rate of 2 km/h till exhaustion. The AT was considered from the ventilatory threshold (VT) measured by non-invasive gas exchange method. The maximum aerobic capacity of Indian middle and long distance runners found to be 62.0 and 68.1 ml/kg/min, respectively, were significantly lower than those of their international counterparts. The mean VO2 of the Indian middle distance runners at AT level was 49.9 ml/kg/min as compared to 48.0 ml/kg/min of the world class runners. The long distance runners also exhibited a lower VO2 at AT level as compared to international runners. It is concluded that, as the AT level is a well established determinant in distance running performance and a significant improvement of maximum aerobic capacity (VO2 max) may not be possible if the runners reach a plateau, more emphasis should be given to improve the AT level of Indian distance runners.
