Abstract

This study aims to determine the effect of the handle on the short-service ability of badminton games in Penjaskesrek students. This research is a pre-experiment, namely two Group pretest-posttest design, the population in the study were 40 students of Physical Education Class 2022, Makassar State University. The data collection technique uses a short service test instrument, namely the forehand grip service test grip. Based on the data analysis, the results obtained from the pretest average value of the forehand grip ability of 32.3500, the average posttest value of the forehand grip of 52.6000, the value of t count> is 7.818, the significance value of the probability is 0.000, and the t table is 2.818. and the mean value of the backhand grip pre-test ability of 32.1500, the average value of, the significance value of the probability of 0.000, and the t table of 2.746. the value of t table 0.050 is greater than t count 0.025 and the value of sig <a (0.000 <0.05), so it can be seen that Ho is accepted and H1 is accepted. This means that there is a significant effect of the effect of the forehand grip of badminton on students by 95%.

Abstract

Pain is a mechanism that occurs due to stimulation of nociceptors as pain receptors that cause ongoing or future tissue damage. Analgesic drugs that are usually used are COX-2 inhibitor drugs that can inhibit the activity of the COX-2 enzyme in synthesizing Prostaglandins (PG) which respond to pain and inflammation. Specific research on active compounds such as corypalmine and panasenoside related to their effects as analgesics has not been widely carried out, so it is necessary to predict the effects of both compounds by analyzing their activity on the COX-2 protein through in silico docking studies. This study aims to see the analgesic activity between the two compounds as COX-2 inhibitors. Testing was carried out through the stages of protein and ligand preparation, method validation, molecular docking of corypalmine and panasenoside compounds with COX-2 and visualization of bonds using Ligplot+. The results showed that the corypalmine docking score was more negative than panasenoside on COX-2, respectively -60.33 and -42.02. It can be concluded that the corypalmine compound is able to bind more strongly to COOX-2 and predicted to have a strong and more stable analgesic effect than panacea.
