Relationship between blood lactate and pain levels during and after maximum resistance exercises
Abstract
The aim of the present study was to examine the relation between lactate concentration and pain during maximum resistance exercises. 14 healthy and non-trained women 39.8 ± 3.9 years, 60.6 ± 6.6 kg and 163.6 ± 6.6 cm were submitted to one maximum repetition test (1-RM) in leg press 45° (LP) and bench press (BP). Fatigue tests (FT) were performed in the same activity apparatus with 48 hours of interval before and after the 26 training sessions. The FT consisted of 3 exercise maximum bouts with 1 minute of interval and 50% of 1-RM. The measurements analyzed were lactate (LAC), lactate/kg of muscle mass (MM), and pain scale at rest, immediately after the 1st, 2nd and 3rd bouts and 5 minutes after the whole exercise. LAC, LAC/kg MM and pain increased during the FT as compared with rest. It was observed a significant increase in the LAC and LAC/kg MM values at rest and after bouts 1 and 2 in LP and BP before and after training. The pain level was not different in the 5 moments of the FT pre and post-training. Furthermore, there was a weak correlation between lactate and pain in LP and BP pre and post-training. In conclusion, the employed FT was capable to increase the lactate response. However, there was not any change in the pain levels, suggesting that the lactate is not a main factor that promotes increased pain during the tests.
