摘要：The purpose of the study was to present an analytical overview of the lactate response and recovery pattern in long distance running. The study was further delimited to long distance runners. viz. 5,000mts and 10,000mts.The Recovery patterns were investigated by Blood Lactate. It was hypothesized that there will be significant recovery in Blood Lactate as a result of different duration of recovery among 5,000 mts and 10,000 mts runners. For the purpose of this study 20 male Junior National level Long distance runners ( 10 athletes each of 5,000mts and 10,000mts) from Tata Athletics Academy, Jamshedpur (Jharkhand) were selected. The age of the subjects ranged between 16-20 years. The blood lactate was measured by lactate scout analyzer and reading was recorded in mmol/liters. The subjects were then asked to run exact distance of their event like a competition in a trial run. Immediately after the finish of the respective races their data was collected on blood lactate. Then the athletes were subjected to active recovery for 15 minutes and the data were again collected on the same variable. The data on biochemical variable i.e. blood lactate was taken in similar fashion subsequently at recovery of 30 minutes and 45 minutes from the finish of the race. The mode of the recovery followed by the athletes was active. In order to analyze and compare the blood lactate recovery pattern of long distance runners of 5,000mts and 10,000 mts , Two way Analysis of variance was used .LSD Post Hoc Mean comparison was applied for the significant F- values. The level of significance was set at 0.05. The long distance running events like 5000mts and 10,000mts are not absolutely aerobic event. The anaerobic proportion of Long distance running 5000mts and 10,000mts is of significant level and fatigue caused in these events are due to anaerobic glycolysis and lactate accumulation is also in significant proportion along with aerobic part of the activity. Lactate response in terms of recovery from the effect of 5000mts and 10,000mts event is directly proportional to duration of rest and recovery period. This signifies more the duration of rest period better will be the lactate recovery. The 15 minutes duration of rest after the event provides significant recovery from fatigue in terms of Blood lactate.
