The coronavirus disease 2019 that becomes a global pandemic has set Indonesian government on high alert. This large-scale issue imposed enormous pressure on the government that leads to the issuance of nationwide distancing policy. The continuous spread of virus, quarantine, and stay-at-home orders for the long period of time contributing to adverse psychological impacts to society. This study investigated the mental health condition during COVID-19 pandemic in adults. This was a cross sectional study that collected demographic data and mental health measurements from April to June 2020. A total of 72 respondents consisted of physically trained and non-trained adults completed a selfadministered online-based survey and Depression, Anxiety, Stress Scale 42 (DASS 42) questionnaire. Independent T-Test and Anova one way were performed to compare the psychological state between groups. The results showed that non-trained groups had higher level of stress (p-value 0,009 < 0,05) and anxiety (p-value 0,009 < 0,05). Findings highlight the importance of exercise to alleviate stress and anxiety. Further interventions and strategies should be done in order to mitigate the pandemic impacts on mental health.
It is well established that regular exercise has many positive benefits on health. Exercise at the appropriate intensity and level has been shown to improve lipid profile and reduce the risk of cardiovascular disease. This study investigates the effect of swimming training on total cholesterol levels and body weight in male Wistar rats. Thirty rats weighing 150-200 grams were randomly divided into one control (C) and two treatment groups (ST=swimming training, SED=sedentary activity). Rats in control (C) group were fed a standard diet, while rats in both treatment groups were fed high-fat diet-induced hypercholesterolemia for three weeks. Rats in ST were then swim-trained at moderate intensity for 30 minutes/day, six days a week for three weeks, and rats in SED were left without exercise stimuli. Body weight was measured weekly. At the end of the experimental period, intracardiac blood samples were drawn to measure the total cholesterol level. Findings revealed that rats’ bodyweight (p=0,045) and blood cholesterol (p=0,034) in ST group were significantly lower compared to SED. It indicates that swimming exercise is shown to be effective in weight loss and reducing blood cholesterol level in hypercholesterolemic rats.
Anemia is still considered as a serious health problem worldwide that requires large attention. Anemia does not only have an impact on health but also affect student achievement. This study aims to identify the prevalence of anemia among female university students in Surabaya and its relationship to academic achievement. This is an observational analytic study with cross-sectional design, involving 92 respondents who were selected using a consecutive sampling method. Data collected by using a questionnaire to obtain respondent characteristics, grade point average (GPA), and menstrual patterns. The measurement of hemoglobin levels carried out using the cyanmethemoglobin method. The results showed that the prevalence of anemia among female students was still quite high and there was a significant relationship between the incidence of anemia and students’ academic achievement measured by grade point average. Female students are one of the groups that are susceptible to anemia, so it is essential to make various efforts to improve Hb levels by increasing the intake of foods high in iron.
This study aims to investigate the effect of imagery training and concentration on the reaction time of students taking fencing extracurricular activities. It was a quasi-experimental research using quantitative approach. A total of 15 respondents were classified into 3 groups, which were control (K) and two experimental groups. Students in experimental groups were given imagery training (E1) and concentration training (E2) for six weeks and reaction times were measured using Electronic Fencing Target-1 (EFT-1) before and after the exercise was given. Data were analyzed using descriptive and inferential statistic using paired t-test and Anova one way, and significance level was set at p=0.05. The results found that the imagery and concentration training had a positive impact on the decrease of reaction time, with significance values of 0.008 and 0.005, respectively. From these results it can be concluded that imagery and concentration exercises can help players to improve their reaction time, so that fencers can react quickly to every movement. OPTIMALISASI WAKTU REAKSI MELALUI LATIHAN IMAGERY DAN KONSENTRASI DALAM OLAHRAGA ANGGAR AbstrakPenelitian ini bertujuan untuk mengetahui pengaruh latihan imagery dan konsentrasi terhadap kecepatan waktu reaksi pada siswa yang mengikuti ekstrakulikuler anggar. Penelitian ini merupakan penelitian eksperimen semu yang menggunakan pendekatan kuantitatif. Sebanyak 15 orang responden dikelompokkan menjadi 3 kelompok, yaitu satu kelompok kontrol (K) dan dua kelompok eksperimen yang diberi latihan imagery (E1) dan latihan konsentrasi (E2). Latihan dilakukan selama enam minggu dan waktu reaksi diukur sebelum dan sesudah latihan diberikan menggunakan Electronic Fencing Target-1 (EFT-1). Analisis data dilakukan secara deskriptif dan inferensial menggunakan uji paired t-test dan Anova one way, dengan nilai signifikan ditetapkan sebesar 0.05. Hasil analisis didapatkan bahwa latihan imagery dan konsentrasi yang diberikan kepada responden memberikan dampak positif terhadap penurunan waktu reaksi, dengan nilai signifikansi secara berturut-turut sebesar 0.008 dan 0.005. Dari hasil ini dapat disimpulkan bahwa latihan imagery dan konsentrasi dapat membantu pemain untuk meningkatkan kemampuan reaksi, sehingga pemain anggar dapat bereaksi dengan cepat terhadap setiap gerakan.
