Abstract

Glucose transporter4 (GLUT4) is the main glucose transporter in skeletal muscle. Impaired GLUT4 expression plays a role in the disorders of glycemic homeostasis such as Type- 2 Diabetes Mellitus (T2DM). Exercise can increase the GLUT4 expression in skeletal muscles so that glucose can get into the cells faster. The intensity of exercise is an important factor in reducing blood glucose levels in patients with T2DM. This study used stored biological material of gastrocnemius muscle from 15 T2DM models of Wistar rats. Rats were divided into three treatment groups namely P0 (no exercise, control), P1 (moderate-intensity continuous exercise), and P2 (vigorous-intensity continuous exercise), and treated for 8 weeks. Glut4 expression was determined by real time-PCR. The relative expression of the Glut4 gene was calculated using the Livak formula. Moderate-intensity exercise increased Glut4 expression by 2.39 times while vigorous-intensity exercise increased Glut4 expression 2.56 times compared to control. The vigorous-intensity continuous exercise expressed higher Glut4 expression than the moderate- intensity continuous one.

Abstract

Background: Neck muscle stiffness is the most common finding of neck pain. The effect of physical activity on neck muscle stiffness is still showing various results. Currently, working from home as the result of COVID-19 pandemic had changed the daily physical activity of each person, including medical students. Objective: This study aims to determine the relationship between physical activity intensity along with total modes of activity and frequency of neck muscle stiffness events. Methods: This is an observational study with cross-sectional study design. Simple randomized sampling was used in this study. Data collection utilized modified EPIC-PAQ2. Data calculated and converted to MET-hour/week and units to assess physical activity intensity and total modes. Results: Physical activity intensity and total modes of activities showed no statistically significant relationship with the frequency of neck muscle stiffness in preclinical medical students in Faculty of Medicine, University of Sumatera Utara. Sex parameter showed significant relationship. Male category showed odd ratio of 0.358 (OR = 0.358, 95% CI) for developing more frequent neck muscle stiffness. Conclusion: More accurate studies have to be conducted to adjust confounding factors on the incidence of neck muscle stiffness.

Abstract

The prevalence of hypertension increases with age, more than 1 in every two elderly has hypertension, dominated by women. The primary prevention of hypertension is a worldwide public health concern. Salat dhuha is a moderate-intensity physical activity. Salat 2 movement cycles demonstrated improved systolic and diastolic blood pressure in adults. Our study purpose was to assess the effect of 2 and 8 movement cycles (rakaat) of salat dhuha to improve systolic and diastolic blood pressure in healthy Muslim elderly women. Muslim elderly women in a government senior residence (aged 60-74 years) participated in a 6 weeks controlled trial. We completed formal physical, clinical, and blood assessments before admission. Participants with hypertension history were excluded. The participants were randomized into 2 groups. The intervention group performed 8 rakaat of salat dhuha (n=13) and the control group performed 2 rakaat of salat dhuha (n=13). Two participants were dropped out of this study. At baseline and at the end of 6 weeks, a blood pressure examination is recorded. Parametric and nonparametric methods were used to analyze the data. The baseline characteristics of the two groups of participants were homogeneous. Compared to the control, the 8 rakaat of salat dhuha achieved a significant reduction in systolic and diastolic blood pressure (P0.05) at the end of the 6-weeks period. The findings show that salat dhuha has significant potential to improve blood pressure.

Abstract

Soccer is the most well known and a phenomenal sport in the world, with around 270 million players registered to this game (FIFA, 2015). Soccer has already attracted attention either sport scientist and government from many countries to promote the benefit of active physical activity and also maintained people’s health, including the minorities and poorest. (Hammami et al, 2016; Milanovic et al., 2015; Parnell et al., 2016). Furthermore, this sport can be used to support the health public program in order to prevent chronic diseases due to cause lack of physical activity (Krustrup et al., 2010).Quality food choices and adequate nutrition nutrient are important for supporting training program and enhancing the physical performance of professional athletes. Macronutrients provide the metabolic substrates necessary for producing the chemical energy required for skeletal muscle contraction and cardiovascular physiology, while the micronutrients help the metabolic reactions involved in energy production and gas transport in the circulation. Soccer is a sport requiring for both aerobic dominant and also anaerobic energy. It needs the players to exercise repetitively at high intensities using large muscle groups for periods of several seconds to several minutes for the full match (90 min) plus added time. Metabolically, athletes depend to a certain extent on their endogenous glycogen stores in the liver and skeletal muscles. Besides from genetic factor, talent and the effort of training, it has been acknowledged that no single factor plays a bigger role in maximaxing physical performance than dietary plan.This Review article was made to show the important role of carbohydrate and dietary fiber in the aspect of soccer game, resumed from scientific articles especially from Europe/USA where soccer was more advanced there. The writer hoped that this article written and published at Indonesia can be used to developed sport science and sport medicine for his beloved country.

Abstract

Melatih teknik bertarung (kumite) dengan cara berhadapan one bye one ditingkat anak usia dini tidaklah mudah secara psikologi anak, sehingga dibutuhkan metode khusus dalam melatih teknik kumite. Penelitian ini bertujuan untuk mengetahui pengaruh model latihan Crazy Ball Game dalam upaya meningkatkan minat dan motivasi anak berlatih kumite di lingkungan Pengkab FORKI Buleleng. Metode penelitian ini eksperimen dengan desain penelitian one group pretest-posttest design. Subjek penelitian adalah anak kategori usia dini (7 s/d 9 tahun) yang terdaftar di aliran/perguruan di bawah naungan FORKI Buleleng sebanyak 50 orang. Berdasarkan hasil analisis dan penelitian yang sesuai dengan penelitian ini, dapat disimpulkan bahwa Model Latihan Crazy Ball Game sangat berpengaruh terhadap minat dan motivasi anak-anak berlatih kumite. Berdasarkan hasil uji hipotesis kedua dalam penelitian (F = 4.614, p = 0,05). Jika ditetapkan taraf signifikansi p = 0,05 maka nilai signifikansi uji hipotesis kedua jauh lebih kecil daripada p, sehingga F signifikan. Maka hipotesis kedua diterima yang artinya terdapat perbedaan yang signifikan terhadap sikap sosial antara siswa yang mengikuti Model Latihan Crazy Ball Game dengan siswa yang mengikuti Latihan konvensional.Practicing fighting techniques (kumite) by dealing with one bye one at the level of early childhood is not easy psychologically for children, so special methods are needed in training the kumite technique. This study to determine the effect of Crazy Ball Game training models in an effort to increase the interest and motivation of children practicing kumite in the FORKI Buleleng regency. The research methods is an experimental research design with one group pretest-posttest design. The subject were fifty childrens of the early age category (7 to 9 years) who were registered in the school of Karate under the auspices of FORKI Buleleng. The result showed that Crazy Ball Game Exercise Model significantly to increase the interests and motivation of children to practice Kumite (F = 4.614, p = 0.05). If the significant level is set p = 005, the significance value of the second hypothesis test is much smaller than p, so F is significant. The the second hypothesis is accepted, which means that there are significant differences in social attitudes between students who take the Crazy Ball Game Exercise Model and students who take conventional exercises.
