Taekwondo is a martial sport that relies on kicks. For a taekwondo athlete to kick, it is necessary to support the explosive power of the leg muscles. This study aims to analyze the relationship between age, sex, body mass index, length of exercise with leg muscle explosive power in taekwondo athletes. Subjects and Methods: This analytic descriptive study used a cross sectional design. The subjects of the study were taekwondo members at Sangkuriang Sports Hall and Lions Gymnasium in Cimahi City, West Java Province, totaling 95 people. The dependent variable is leg muscle explosive power. The independent variables were age, gender, body mass index and duration of exercise. The instruments used are questionnaires and vertical jump measuring instruments. Data were analyzed bivariately using OR and chi square test. The explosive power of the limbs increased with increasing age (OR= 2.89; 95% CI= 1.23 to 5.77; p= 0.010) and duration of exercise (OR= 7.44; 95% CI= 2.96 to 18.67; p <0.001). Leg explosive power decreased with body mass index but not statistically significant (OR= 0.72; 95% CI= 0.30 to 1.18; p= 0.600). Gender increased limb explosive power, but not statistically significant (OR= 1.14; 95% CI= 0.51 to 2.56; p= 0.900). The explosive power of the limbs increases with age and duration of exercise. The relationship between limb explosive power and sex and body mass index was not statistically significant

Background: Pregnancy causes physiological changes that affect the musculoskeletal system and usually poses a risk of low back pain. This study aims to analyze the effect of kinesiotaping on reducing low back pain in pregnant women based on the results of a number of previous primary studies. Subjects and Method:This study uses a meta-analysis method with articles searched using the search keywords "Low back pain" OR "pelvic girdle pain" AND "pregnancy" OR "kinesiotaping" OR "kinesio tape" AND "pain reduction" OR "VAS" AND " Randomized Controlled Trial" OR "RCT" from PubMed, google scholar and science direct and processed using RevMan 5.3. The independent variable is kinesiotaping and the dependent variable is low back pain. Results: 9 RCT articles that fit into the inclusion criteria, with a total of 572 samples. Pregnant women with low back pain who received kinesiotaping had an average VAS score of 1.23 units lower than those without kinesiotaping, and the effect was statistically significant (SMD= -1.23; 95% CI -2.30 to -0.16; p= 0.02). In other words, kinesiotaping is effective in reducing low back pain in pregnant women. Conclusion: Kinesio Taping has an effect on reducing low back pain in pregnant women.

Background:The COVID-19 outbreak rapidly spread worldwide, with a significant number of cases and deaths causing anxiety, especially among the sufferers. Biologically, males and females show different psychological responses to the events at hand. This study aimed to examine the association between gender and anxiety among COVID-19 patients. Subjects and Method: This study was a meta-analysis. The articles were obtained from databases PubMed and Scopus using keywords "Anxiety" OR "anxiety disorder" AND "COVID-19 Patients" OR "Patients with COVID-19" OR "Hospitalized" AND "Risk factors" OR "determinants" OR "Gender" OR "Factors associated". The articles included in this study were full-text with a cross-sectional design, discussed the association between gender and anxiety among COVID-19 patients, published in English, studies located in Asia. The final results were presented in Adjust Odds Ratio (aOR) or Standardized Mean Difference (SMD). Data analysis was performed using Revman 5.3 software, with generic inverse variance data type for categorical outcome group (CtOG) articles and continuous data type for continue outcome group (CnOG). Results: 9 articles were analyzed, including 4 articles CtOG and 5 articles CnOG. The forest plot of both categorical and continue outcomes showed consistent result that among COVID-19 patients who hospitalized with mild to severe symptoms. Female patients significantly had higher anxiety event (aOR= 2.19; 95% CI= 1.60 to 2.99; p<0.001; I 2 = 0% and SMD= 0.35; 95% CI= 0.21 to 0.49; p<0.001; I 2 = 12%). Conclusion: Among COVID-19 patients, the female gender has a significantly higher risk of suffering from anxiety than the male gender.
