BACKGROUND: Delayed Onset Muscle Soreness (DOMS) is a common injury resulting from abnormal intensive training in athletes, mainly the result of training involving eccentric contractions. AIM: The aim of this study was to determine the correlation between the incidence of DOMS and HMGB1 as a marker of the occurrence of inflammation post Exercise Induces Muscle Damaged. METHOD: 28 male recreational students of Sports Science Department, Universitas Negeri Surabaya who met all inclusion and exclusion criteria participated in this study. Participants completed a muscle damaging exercise which consists of a 10x10 drop jump (DRP) and a bout of 40×15 m sprints with a 5 m deceleration zone (SPR) to obtain a muscle damage effect. In this study, the stretching in the exercise session was not given, this was done to get the DOMS effect after exercise. DOMS and HMGB1 was carry out 1 hour before the exercise, 12 hours after the exercise, 24 hours after the exercise and 48 hours after the exercise. RESULT: The result showed that there was a significant correlation (r=0.935, p<0.05) between DOMS and HMGB1 as a predictor of inflammation. The participants that were given EIMD eccentric exercise (DRP and SPR) showed the occurrence of DOMS and increasing of HMGB1. The result also showed that there was a correlation between DOMS and HMGB1. CONCLUSION: This study concluded that there was a correlation between DOMS and HMGB1 as a marker of inflammation as the result of the eccentric exercise of the exercise Induced Muscle Damage (EIMD).

Background: intense exercise causing an increase in substrate utilization by the working muscles, resulting in an increased use of oxygen. Increased oxygen consumption associated with activation of specific metabolic pathways due to exercise activity then triggers increased Reactive Oxygen Species (ROS) production. The increase in free radicals (ROS) can further cause cell damage. Kencur (kaempferia galanga) is a plant that is believed to have bioactive compounds, including phenolic compounds that have antioxidant activity. Objectives: The aim of this study was to determine the effectiveness of 15-days supplementation kencur (kaempferia galanga linn) on plasma MDA and IL-6 post aerobic exercise activity. Methods: This study was quasy experimental study, with a pretest - Post Test Control Group Design. A total of 30 Sports Science students of Universitas Negeri Surabaya who met the inclusion and exclusion criteria participated in this study. The participants divided into 2 groups, the kencur extract group (KG) of 200 mg/day and the placebo group (Pl). The supplementation was carried out for 15 days (14 days before and 1 day after aerobic exercise). Participants completed aerobic exercise (AE) consisting of 2x800 m with 2-minute intervals. Measurements of plasma MDA and IL-6 were 24 hours after AE. The difference test used repeated measures ANOVA with a significance level of P<0.05. Results: there was a significant difference in the plasma MDA and IL-6 between each group with the significance value of MDA was p = 0.000 and the significance value of Il-6 was p<0,001 Conclusions: Supplementation of kencur extract (Kaempferia Galanga Linn) for 15 days was effective to reduce the increase of oxidative stress (MDA) and the increase in pro-inflammatory cytokines (IL-6) after the implementation of aerobic exercise activities.

BACKGROUND: Pencak Silat is a self-defense exercise originated from Indonesia and categorized as a high-intensity exercise. AIM: This research was intended to identify the acute response of Pencak Silat basic exercise toward interleukin-6 (IL-6) as an immune system biomarker on students of Perguruan Pencak Silat Perisai Diri Tulungrejo, Bojonegoro. METHODS: A number of 26 students (10 boys and 16 girls) of Perguruan Pencak Silat Tulungrejo, Bojonegoro, were participated in this study. The students did the 2 h Perguruan Pencak Silat Perisai Diri, Bojonegoro, training program with 75–85% intensity. The IL-6 serum was measured using ELISA method. RESULTS: The result of this study showed that the IL-6 serum level in post-2 (12 h after training) (6.2981 pg/mL) was higher compared with the IL-6 serum level in post-1 (shortly after training) (6.11981 pg/mL) and before training (4.5146 pg/mL). The result also showed that there was a significant difference of IL-6 levels between pre-training and after training. CONCLUSION: This study concluded that the basic exercise performed by the new students of Perguruan Pencak Silat Perisai Diri increased IL-6 serum level.

The prevalence of obesity of adult women in Indonesia has increased recently. Obesity among adult women will lead to health problems such as diabetes until coronary heart disease. The aim of this quasy experimental study was to determine the effectiveness of the 8-week exercise program combining low impact aerobics and yoga on the percentage of body fat in women in 2017. The subjects of this study were 12 Unesa female studentss with criteria to have Body Mass Index (BMI) obese category with age 19-24 years. The effectiveness of the 8-week low-impact exercise program of aerobics and yoga on the percentage of body fat was measured using anthropometric methods with skinfold caliper techniques measured before and after the treatment of training programs. Based on the results of calculations using t test on the percentage of body fat then 8-week exercise program combination of low impact aerobics and yoga effective in reducing body fat with an average percentage decreased of 10.56%.

Delayed Onset Muscle Soreness (DOMS) is a pain that occurs after uncustomized eccentric exercise and can happen to anyone, both those who are athletes and other individuals. DOMS is usually felt 24-72 hours after exercise or activities that use eccentric movements, which interfere with the athlete’s training activities and other individuals’ daily activities. This study aimed to determine the effectiveness of kencur extract supplementation (kaempferia galanga linn) on DOMS and creatine kinase (CK) plasma levels after eccentric exercise. This research is quasi-experimental, using a randomized control group design as the design in this study. Research subjects (n = 28) were randomly divided into 2 groups, namely the kencur extract group (200 mg/day) and the placebo group (corn flour). The supplementation process in both groups was carried out for 5 days (3 days before and 2 days after) the eccentric exercise. DOMS pain (VAS) and blood samples (CK plasma) were taken 24 hours (pre) and 48 hours (post) after eccentric exercise. The destructive drill uses the 5 x 20 Eccentric depth jump drill. The data obtained in the form of changes in DOMS pain and CK plasma were then analyzed using ANOVA with sig. 0.005. Supplementation of galingale extract was effective in reducing DOMS pain with p = 0.008 (0.05) and CK plasma value p = 0.000 (0.05) compared to placebo after eccentric exercise. Supplementation of galingale extract (Kaempferia Galanga Linn) for 5 days is effective as an effort to reduce the risk of DOMS pain sensation and reduce the increase in muscle damage with CK as a marker after eccentric exercise.
