Abstract

Reactive Oxygen Species (ROS) are produced by humans as a result of cellular metabolism and environmental factors such as pollutants or cigarette smoke. ROS is a very reactive molecule and has the ability to damage cell structure. Oxidative stress is a condition between oxidants and antioxidants that is not balance, pathophysiologically, oxidative stress can trigger the risk of various diseases including hypertension, atherosclerosis, diabetes, heart failure, stroke and other chronic diseases. Oxidative stress can be overcome by intake of antioxidants. The purpose of this study was to determine the antioxidant activity contained in the meat and shells of a knife scallop (Solen sp.) that lives in Bangkalan waters, Madura. The method used in this study is an analysis of antioxidant activity with the DPPH method. Knife scallop has antioxidant activity which is evident from the IC50 values obtained. IC50 values of the shell and meat extract with ethanol solvent were 489.56 ppm and 748.49 ppm. IC50 values of the shell and meat extract with ethyl acetate solvent were 916.43 ppm and 2045.93 ppm. While the IC50 value of the shell and meat extract with chloroform solvent was 119.37 ppm and 1692.80 ppm. Based on IC50 data of knife scallop shell and meat extracts on the 3 types of solvents, it can be concluded that knife scallop’s shell and meat extract with ethanol solvent has the greatest antioxidant activity compared to ethyl acetate and chloroform solvents.

Abstract

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.

Abstract

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.

Abstract

Physical activity plays an important role in adolescents' mental health. Increased activity can help reduce levels of stress, depression, and anxiety. This study aims to analyse the relationship between physical activity levels and mental health conditions in 220 students of Al-Islam Krian High School with an age range of 17 to 19 years, consisting of 70 male students (30%) and 150 female students (70%). This research design uses quantitative descriptive method through observation. The instruments used were the International Physical Activity Questionnaire Short Form (IPAQ SF) to measure physical activity levels and the Depression Anxiety Stress Scale 21 (DASS 21) to assess stress, depression, and anxiety. The results showed that 10% of students had low physical activity, 59% were moderate, and 31% were high. Data were analysed using SPSS 29 with the significance results of stress (p = -0.067), depression (p = -0.044), and anxiety (p = -0.031). Based on correlational analysis, it was found that there was no significant relationship, but it was negative. This means that the higher the physical activity, the lower the levels of stress, depression, and anxiety. Physical activity does not directly play a role in mental health factors, but has a tendency to reduce stress, depression, and anxiety in adolescents.
