Abstract

This study aims to test the administration of ethanol extract of cat's whisker leaves (Orthosiphon stamineus) to reduce cholesterol levels in female Sprague Dawley rats. This type of research is a quasi-experiment design using a one group pre-test and post-test design. The population in this study was 30 female Sprague Dawley rats aged ± 3 months with a body weight of around 150-250 grams. Data were analyzed using the t test statistic at = 5%. The results of the research showed that the highest decrease in cholesterol levels was in female Sprague Dawley rats at a test dose of 1000 mg/kgBW and there was an effect of ethanol extract of cat's whisker leaves (Orthosiphon stamineus) on reducing cholesterol levels in female Sprague Dawley rats

Abstract

Background: Futsal is now one of the most popular sports in the community. This can be seen from the existence of futsal courts in almost every region, whether they meet the standards or not. This achievement sport is well organized, has a planned program, and sets certain targets to reach the peak of achievement. One important component in the physical condition needed in the game of futsal is the explosive power (power) of the leg muscles. Explosive power is defined as the ability of a muscle to face resistance with a very fast contraction. This concept includes a combination of strength and speed of muscle contraction that is dynamic and explosive, where the muscle must release maximum strength in the fastest possible time. Objective: To determine the effect of giving Plyometric Hurdle Jump on lower limb muscle explosiveness in futsal players. Methods: This study uses an experimental type with a quasi-experimental approach pre test and post test design with one group. The sample of this study amounted to 15 people with meetings 2 times a week for 8 meetings. Results: normality test with Shapiro Wilk Test obtained data before and after not normally distributed p <0.05. Based on the analysis using the Wilcoxon test, the p-value = (0.002 <0.05) then Ha is accepted and H0 is rejected. Conclusion: there is an effect of Plyometric Hurdle Jump on the explosive power of the lower leg muscles of futsal players
