BACKGROUND: Memory function disorder is a major health problem in geriatric patients. Physical exercise has the potency to decrease the incidence of many degenerative and chronic health problem, related to cognitive deterioration (dementia). AIM: This research aimed to observe the effect of physical exercise in various doses and duration on memory function by analysing the role of Brain-Derived Neurotrophic Factor (BDNF) as a regulatory protein affected by exercise. METHODS: This was an analytical observational study with a cohort design. Thirty participants were included in each group, classified as exercise and non-exercise group. The exercise was in the form of jogging for at least fifteen minutes every day. The observation was done for sixty days. Cognitive function assessment was done by using the Mini-Mental State Examination (MMSE) questionnaire. Meanwhile, the BDNF level was assessed by ELISA. Statistical analysis was done using Independent T-test. RESULTS: Exercise group showed better MMSE score (28.56 ± 1.76), and a higher concentration of BDNF (235.34 ± 12.56 pg/mL), both were statistically significant. CONCLUSION: Physical exercise was able to maintain geriatric cognitive function performance by BDNF protein regulation.
BACKGROUND: Depression is very common in the elderly population. Physical exercise is one of the non-pharmacological procedures that promise to be a solution to improve the severity of depression. Brain-Derived Neurotrophic Factor (BDNF) plays a role in maintaining the survival of neuronal cells and in the regulation of synapse plasticity, affecting serotonin production in the hippocampus and thus the depressive symptoms. AIM: This study aimed to assess the role of physical exercise in affecting BDNF levels in elderly with depression. METHODS: Thirty-five elderly women (age ≥ 50 years) with depressive episodes based on Diagnostic and Statistical Manual of Mental Disorders (DSM)-V criteria were enrolled as treatment group, and 35 elderly women without depressive episodes were enrolled as control group, and underwent physical exercise in the form of treadmill with a speed of 6 km/h for 15 minutes. Physical exercise was carried out once a day for 28 days. As much as 1 ml of blood from the study, subjects were obtained from the cubital vein before the exercise commenced. Brain-Derived Neurotrophic Factor (BDNF) serum level was assessed by Enzyme-Linked Immunosorbent Assay (ELISA). Data were presented in the form of mean ± SD. An independent T-test was used to test levels after exercise in the depression group compared to the non-depression group. RESULTS: Pre-exercise BDNF levels in the depression group were lower than the group of elderly without depression. Physical exercise increased BDNF production in both elderly groups with and without depression. In the depression group, the increasing percentage of BDNF level was higher compared to non-depressive elderly. CONCLUSION: The increasing percentage of BDNF level was found to be higher in depressive elderly performing physical exercise. Physical exercise may be beneficial in supporting the therapy of elderly with depression.
This study aims to determine the effect of various push up exercises on the results of passing over in extracurricular volleyball activities for male students of class VIII Muhammadiyah Junior High School Megang Sakti, Musi Rawas. This type of research is a quasy experiment with a pretest-posttest one group design. The sample in this study amounted to 30 people. The instrument used was a passing test on the wall. The treatment in this study was in the form of various push-up training methods, after being given exercise for 6 weeks with a frequency of training 3 times a week. Based on the results of research and data analysis with statistical t test with a significant level of α = 0.05, it was obtained tcount (0.10) while ttable (1.70), then tcount> ttable, then Ha was accepted and Ho was rejected. Thus Ha can be submitted it can be accepted, that the push up exercise varies with the results overhead pass in the volleyball extracurricular activities of male students class VIII Junior High School Muhammadiyah Megang Sakti Musi Rawas. The findings in this study are the results of training methods of variation push up that can be used to improve the ability overhead pass volleyball. The implication of this research is that various push up exercises can be used as a type of exercise to improve of the volleyball overhead pass ability. This research was conducted in junior high schools and the samples were students who took volleyball extracurricular activities, so this study was aimed at novice athletes or new to volleyball, so this research is suitable for beginners.
Penelitian ini bertujuan untuk mengetahui hubungan antara kekuatan otot lengan dan kelentukan togok dengan hasil servis atas bola voli. Penelitian ini dilaksanakan selama 1 minggu di lapangan bola voli SMK Negeri 2 Palembang. Metode yang digunakan adalah metode korelasi dengan instrumen tes dan pengukuran, dengan bentuk tesnya yaitu melakukan pull up, sit and reach. Populasi penelitian adalah siswa putra yang mengikuti ekstrakurikuler bola voli berjumlah 30 orang. Hasil pengolahan dan analisis data menunjukkan hubungan kekuatan otot lengan terhadap hasil servis atas bola voli sebesar 0,61 dengan sumbangan efektif sebesar 8,96 %, hubungan kelentukan togok terhadap hasil servis atas sebesar 0,42 dengan sumbangan efektif 24% dan hubungan kekuatan otot lengan dan kelentukan togok terhadap hasil servis atas bola voli sebesar 0,45 dengan koefisien determinasi 50%. Penelitian ini dilakukan dengan cara melakukan servis atas menyebrangi net lawan yang diberi nilai-nilai dengan 6 kali percobaan. Dengan hasil analisis regresi ganda kekuatan otot lengan dan kelentukan togok dengan hasil servis atas F.hitung 13,5, F.tabel 5,49. Berdasarkan hasil penelitian tersebut, maka dapat disimpulkan bahwa terdapat hubungan yang cukup signifikan pada kekuatan otot lengan dan kelentukan togok dengan hasil servis atas bola voli SMK Negeri 2 Palembang.
Hospital as one of health public services institution on delivering health services supported by multidiscipline professions that have diversity of personality. Personality is one of factor contributed in triggering interpersonal conflict at workplace. There are five interpersonal conflict managements commonly used, namely ; integrating, obliging, dominating, avoiding dan compromising. Research was conducted on March 2015 at Eye Specialist Hospital South Sumatera Province which 75 respondens as samples of the reaserch. The objectives of this reaserch to explore differences among type A and B personality toward interpersonal conflict management in the hospital. Cross Sectional Study as design of the reaserch with Manova and Post Hoc test analyisis. From this reaserch found that type A personality is dominant personality of employee, and dominant interpersonal conflict management is integrating style. Based on the risult of Post Hoc analysis shown that significant difference between type A and B personality towrad management conflict of interpersonal found on obliging style with P value 0,000 < 0,05, for other management conflict style was not found.
Technology and education development are expected to make teachers easier to create and produce learning media used practically and efficiently. This study used the research development (R&D) method proposed by Borg and Gall, consisting of ten research steps. It aimed to develop a preliminary product design for a digital-based flexibility test measuring instrument. This research produces a body flexibility measurement tool for physical education subjects, particularly physical fitness. The participants of this study were Tanjung Lago 1 Public Middle School students validated, revised, and tested on small and large scales. Three experts validated this research through a questionnaire of various kinds of questions, i.e.1) an expert in sports tests and measurements, namely a lecturer at PGRI Palembang University (94% in the very compatible category), 2) an expert in electrical media from C.V. Cometronica Palembang (82% very appropriate category), and 3) the teacher of Physical education from SMPN 1 Tanjung Lago (97% very proper category). The three experts reveal that an average of 91% of the digital-based sit and reach box applied to measure flexibility tests is worthy. It is supported by the statistical results of small-scale trials with normality tests of 0.200, homogeneity tests of 0.785, and paired sample t-tests of 0.785, statistical results of large-scale trials with normality tests of 0.200, homogeneity tests of 0.64, and paired sample t-test of 0.299. This study indicates that the digital-based sit and reach box tool developed and tested for meeting validity and effectiveness can be implemented in teaching and learning activities. Key words: development, flexibility, digital.
