Background and Objective: Life style with Low activity and overweight increased the risk of cardiovascular diseases. This study was done to evaluate the effect of ginger supplementation on Lactate dehydrogenase (LDH) changes and delayed muscle soreness following exhaustive eccentric exercise on overweight girls.
Methods: In this randomized clinical trial study, 22 overweight girls were randomly divided into the two groups including intervention (n=12) and control (n=10) groups. For subjects in interventional group were used a daily supplement of 2 grams of ginger powder, each serving a capsule, containing one gram of ginger powder  and subjects in control group were received  daily two capsules containing starch, for two weeks. Physical activity was performed consisting of two sessions of exhausting activity (negative tilt on treadmill, one session before supplementation and one session after two weeks of supplementation). Blood samples were measured in order to measure changes in LDH in four stages and the use of the pain questionnaire for evaluation of delayed muscular brittleness in both pre and post gingival supplementation. Pain scale (visual analogue scale: VAS) was used to measure the delay fatigue.
Results: The results showed that extrinsic exercise increased LDH and delayed muscle soreness after exercise (P<0.05). Also, taking two weeks of ginger supplementation significantly reduced LDH and delayed muscle soreness in the supplement group in comparison with controls (P<0.05).
Conclusion: Ginger can reduces the muscle gain and delayed onset muscle soreness resulting from eccentric exercise in overweight girls.
