The purpose of this study was to observe the relationship between effects of different workload and load volume (i.e. 3 RM, 6 RM, 9 RM) of power clean on blood lactate production in female weight lifters. A total of six weight lifters with mean age, height and weight of 20.5 ±2.8 years, 161± 6.5cm and 70±7.4Kg respectively volunteered to participate in this study. Each subject‘s blood lactate was measured at rest and after 3RM, 6RM & 9RM with the help of a digital portable lactate analyzer (Lactate Scout) and the data were analyzed using Mean ±SD, T-test and correlation (Pearson).The maximum mean of relative absolute and %percent increase of blood lactate was 8.7±2.3mmol and 370.0±109.3% (3RM) followed by 7.4±2.0mmol & 349.8±112.0% (6RM) and 5.33±1.96mmol &33.3±81.3% (9RM).The difference in blood lactate at rest and after the execution of different work load volume was statistical significantly (p < .05). Insignificant correlation was found between the load lifted, load volume and posttest blood lactate in 3 RM, 6 RM and 9 RM. But when the data of different work load volume pattern was pooled together, there was a statistical significant negative correlation between load volume, posttest blood lactate (r = -0.63, p<.01), relative absolute (r = -0.61 p<.01) and percent increase in blood lactate (r = -0.57, p<.05). It was concluded that the blood lactate response depends upon the maximum absolute load lifted by the weight lifters as compared to the volume of load lifted. In other words, we can say that blood lactate production was largely dependent on the percentage of 1RM lifted.
