[Effect of ginger root powder on inflammatory and anti-inflammatory responses induced by resistance training Delrome style in male volleyball players]

Background and Aim: the aim of this study was to evaluate the effect of ginger root powder on inflammatory and anti-inflammatory responses induced by resistance training Delrome style in male volleyball players

Materials and Methods: 20 male volleyball players were randomly assigned to experimental [n=10] and placebo [n=10] groups. The first set of light to heavy training programs was performed at 50% of 1RM, the second set at 75%, and finally at 100% of 1RM. Ginger supplement capsules were consumed three times a day for a week [total dose of 3 g]. Blood samples were collected from the subjects after 12 hours of fasting at the baseline and after each set of exercise. Data were analyzed by dependent t-test and ANOVA repeated measures. P<0.05 was considered significant

Results: the results showed that the levels of cortisol increased at rest and immediately after exercise in the experimental group compared to the cortisol levels in the placebo group. However, it reduced 24 hours after training, but this reduction was not significant. IL-10 levels reduced significantly immediately after exercise in the experimental group [P=0.01]. Also, the levels of TNF-alpha before and after supplementation reduced significantly in the experimental group [P=0.018]

Conclusion: although Delrome style training increases inflammation, use of ginger before training can lead to more beneficial effect on exercise induced Inflammation

[Effects of active recoveries with and without creatine on inflammatory markers and physical performance in young women after bouts of maximum swimming]

Background and Aim: the aim of this study was to evaluate the effects of active recoveries in and out of the water with and without creatine monohydrate consumption on some inflammatory markers and physical performance after six bouts of maximum intermittent swimming in young women

Materials and Methods: sixteen healthy non-elite swimmers in a semi-experimental study were randomly assigned to 2 groups of in and out of the water active recoveries. They performed six repeated sprints swimming bouts of 50-m in and out of water, with rest intervals of 120 seconds. The subjects received supplementation 4 times a day for 6 days. Data were analyzed using ANOVA, Bonferroni test and also independent t-test. P<0.05 was considered significant

Results: the results showed that there was no significant difference between the effect of in and out of the water recovery on the level of IL-6 [P=0.110] and the VCAM1 [P=0.012] following frequent maximum intermittent swimming. There were significant differences within each group in the levels of IL-6 [P=0.042] and VCAM1 [P=0.012] after creatine supplementation. The percent of speed reduction changes as a fatigue indicator in the water recovery groups showed significant difference between before and after creatine supplementation [P=0.005]. There was no significant difference between before and after creatine supplementation in the out of water recovery group [P=0.155]

Conclusion: recovery, in particular, in water [IN] type, following short-term creatine supplementation modulates systemic inflammation and improves physical performance after high-intensity interval training
