Analysis of Changes in Malondialdehyde (MDA) and Lactate Dehydrogenase (LDH) Levels After a 30 km Cycling Event in The Makassar Cycling Community

This study looks at the changes in MDA and LDH levels after a 30 km cycling event Makassar community. research is pre-experimental with one-group pretest-posttest design on male cyclists aged 30-60 years. The pre-test was carried out day before event, then post-test 2 hours event. Blood samples were tested using ELISA Kit. Data analyzed Wilcoxon test to see effect of levels. Spearman correlation between LDH. results found that had significant due lipid peroxidation (p<0.05) increased lactate secretion (p<0.05). There no (p=0.60) negative correlation, which means more change levels, lower level.
