Background: Sensation in the form of pain, edema, and stiffness that increases 24-48 hours after high-intensity training, especially eccentric exercises is called Delayed Onset Muscle Soreness (DOMS). One method to accelerate the recovery process and reduce the pain caused by DOMS is with Branched-Chain Amino Acid (BCAA) supplementation. However, until now, there has been limited research that proves the difference in the effectiveness of supplementation time between before and after exercise. Objectives: The aim of this research was to determine the difference in the effectiveness of BCAA supplementation time on DOMS.Methods: This research was an experimental research. A posttest only control group design approach was carried out to measure the effectiveness of supplementation on DOMS as measured by VAS at 24 hours after exercise. A pre and post control group design approach was carried out to measure the effectiveness of supplementation on the alteration in Range of Motion (ROM) as measured by the modified Lower Extremity Functional Scale (LEFS) questionnaire before exercise and 24 hours after exercise. The subjects were classified into 3 groups, namely the control group, 30 minutes before exercise supplementation, and 1 hour after exercise supplementation. Data were analyzed by one way ANOVA and Kruskall Wallis tests. Results Total sample in this study was 30 people. The result of oneway ANOVA test for differences in the effectiveness of BCAA supplementation on VAS was p<0.001. The result of post hoc test between the control and before and after exercise supplementation group was p<0.001, while between the before and after supplementation group was p=0.113. The result of Kruskall Wallis test to measure the effectiveness of supplementation on the alteration (Δ) in LEFS was p=0.336Conclusion: There was no significant difference in the level of pain between the before and after BCAA supplemented group. However, there were significant differences in the level of pain in both of the before and after supplementation group with the control group. There was no significant differences in the alteration of ROM between the three groups

Abstract. Delayed onset muscle soreness (DOMS) is a symptom of exercise-induced muscle damage that occurs following exercise. Previous research has indicated that branched-chain amino acid (BCAA) supplementation may attenuate exercise-induced muscle damage that causes delayed onset muscle soreness, however the results are inconsistent. The primary aim of this study was to examine the previous literature assessing the effect of BCAA supplementation on DOMS following an acute bout of exercise in adults. This review was conducted in accordance with PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses), and identified peer-reviewed articles comparing a BCAA supplement to a placebo non-BCAA supplement following an acute bout of exercise. An electronic search of three databases (EbscoHost, Web of Science, and SPORTDiscus) yielded 42 articles after duplicates were removed. All studies included in the current analyis were: 1) peer-reviewed publications; 2) available in English; 3) utilized a random control design that compared a BCAA group to a placebo control group following exercise; 4) and assessed soreness of muscle tissue during recovery. DOMS was assessed in 61 participants following ingestion of a BCAA supplement over the course of these interventions. The cumulative results of 37 effects gathered from 8 studies published between 2007 and 2017 indicated that BCAA supplementation reduced DOMS following exercise training (ES = 0.7286, 95% CI: 0.5017 to 0.9555, p < 0.001). A large decrease in DOMS occurs following BCAA supplementation after exercise compared to a placebo supplement.

This study aims to observe the effectiveness of therapy of reflective-intuitive reading of Al-Fatihah in reducing the depression of autoimmune survivors. It used the quasi-experiment with the pre-test-posttest control group design – not non-randomized pretest-posttest control group design. The subjects involved in this study were the female Moslems becoming the survivors of one of the autoimmune diseases. Here, the level of depression of the subject was measured using the Depression Anxiety Stress Scale (DASS) sub-test of depression developed by Lovibond and Lovibond, adapted into the Indonesian language. The implementation of the therapy refers to the module of reflective-intuitive reading of Al-Fatihah developed by the researcher and team by referring to the module owned by Maulana, Subandi and Astuti. Data analysis used the Mann Whitney U-Test to determine the difference in the depression level in the experimental group before and after the intervention compared to the control group. The study results showed that therapy of reflective-intuitive reading of Al-Fatihah effectively reduced the level of depression of autoimmune survivors after passing the changing process taking a particular time.

The authors examined the effect of branched-chain amino acid (BCAA) supplementation on squat-exercise-induced delayed-onset muscle soreness (DOMS) using 12 young, healthy, untrained female participants. The experiment was conducted with a crossover double-blind design. In the morning on the exercise-session day, the participants ingested either BCAA (isoleucine:leucine:valine = 1:2.3:1.2) or dextrin at 100 mg/kg body weight before the squat exercise, which consisted of 7 sets of 20 squats/set with 3-min intervals between sets. DOMS showed a peak on Days 2 and 3 in both trials, but the level of soreness was significantly lower in the BCAA trial than in the placebo. Leg-muscle force during maximal voluntary isometric contractions was measured 2 d after exercise (Day 3), and the BCAA supplementation suppressed the muscle-force decrease (to ~80% of the value recorded under the control conditions) observed in the placebo trial. Plasma BCAA concentrations, which decreased after exercise in the placebo trial, were markedly elevated during the 2 hr postexercise in the BCAA trial. Serum myoglobin concentration was increased by exercise in the placebo but not in the BCAA trial. The concentration of plasma elastase as an index of neutrophil activation appeared to increase after the squat exercise in both trials, but the change in the elastase level was significant only in the placebo trial. These results suggest that muscle damage may be suppressed by BCAA supplementation.

The purpose of this study was to see the comparison between the administration of Massage Counterpressure and the provision of dark chocolate to reduce menstrual pain (dysmenorrhoea). The design uses a quasi-experimental design with two groups of pretest and posttest with control group design. The results showed that in the dark chocolate and anti-pain medication group, massage counterressure and anti-pain medicine obtained ρ value of 0,000. there are significant differences before and after the administration of action. The results of the man whitney test found that there were differences between the 2 groups with a value of ρ value of 0,000. Conclusion, there is a difference of influence between the dark chocolate group and the counterpressure massage group on the intensity of menstrual pain. Giving 100 grams of dark chocolate for 2 days and anti-pain medication is more effective than a 20-minute counterpressure massage for 2 days and anti-pain medication for menstrual pain intensity.   Keywords: Dark Chocolate, Massage counterprssure, Menstrual pain
