Kecepatan lari dalam olahraga basket sangat dibutuhkan, karena pemain harus memiliki kecepatan dribblingatau menggiring bola yang cepat serta dapat membelokkan arah bola dengan cepat. Permasalahan dalam strukturdan fungsi tubuh seperti genu valgum akan memberikan pengaruh pada kecepatan lari pada atlet yang dapatmempengaruhi performa dan prestari atlet. Penelitian ini bertujuan untuk mengetahui perbedaan kecepatan lari padapemain basket putri dengan genu valgum normal dan abnormal. Desain penelitian ini yaitu analitik denganpendekatan potong lintang. Jumlah sampel sebanyak 46 pemain basket putri berusia 16 – 19 tahun. Variabel bebasyang diukur adalah genu valgum normal dan abnormal sedangkan variabel terikatnya yaitu kecepatan lari. Hasilpenelitian menunjukkan nilai p = 0,000 (p< 0,05) dengan nilai rerata kecepatan lari pada kelompok genu valgumnormal dan abnormal masing masing 10,83 ± 0,61 detik dan 12,13 ± 1,02 detik. Kesimpulan dari penelitian ini yaituterdapat perbedaan kecepatan lari yang signifikan pada pemain basket putri dengan genu valgum normal danabnormal, dimana kecepatan lari pada kelompok genu valgum abnormal lebih rendah sebesar 11,32% dibandingkandengan kelompok genu valgum normal.Kata Kunci: Genu valgum, Kecepatan Lari, Q-Angle, Pemain Basket
Abstrak: Pada tahun 2010, prevalensi kanker leher rahim di Provinsi Bali terus meningkat hingga mencapai 43/100.000, dan di Kota Denpasar mencapai 25/100.000. Lesi prakanker dapat diketahui dengan metode inspeksi visual asam asetat (IVA) dan kejadiannya diperkirakan delapan kali jumlah kanker leher rahim yaitu 184/100.000. Penelitian kasus kontrol ini bertujuan untuk mengetahui risiko terkait meliputi hubungan seksual, merokok dan higiene diri terhadap lesi prakanker. Penelitian melibatkan 60 kasus (IVA positif) dan 60 kontrol (IVA negatif) yang diambil dari register kunjungan IVA Agustus 2010-Desember 2011. Penelitian dilakukan di dua puskesmas yang melayani IVA di Denpasar. Sampel didatangi ke rumah masing-masing dan diwawancara dengan kuesioner See and Treat yang dimodifikasi. Higiene diri diukur dari frekuensi mandi, cara cebok, pemakaian sabun/pengharum, cebok setelah hubungan seksual, frekuensi ganti pembalut, frekuensi cuci vagina, pemakaian toilet dan pemakaian pentiliner. Analisis data dilakukan secara univariat, bivariat dengan uji chi square dan multivariat dengan regresi logistik untuk mengetahui faktor risiko yang paling dominan. Umur responden adalah 24-56 tahun (mean 41,76). Sebagian besar responden berpendidikan ≥SMA (87,5%), pekerjaan swasta (47,5%), umur menikah pertama kali >20-25 tahun (41,7%), paritas 2 (42,5%) serta tidak memiliki riwayat kanker pada keluarga (83,3%). Higiene diri kurang baik meningkatkan kejadian lesi prakanker leher rahim sebesar 29 kali [OR=29,57; 95%CI 10,51-83,17]. Dari delapan indikator higiene diri, OR tertinggi adalah frekuensi mengganti pembalut (16,44). Paparan asap rokok >4 jam perhari meningkatkan kejadian lesi prakanker leher rahim sebesar 4 kali [OR=4,75; 95%CI 2,19-10,33]. Hasil analisis regresi logistik menemukan bahwa faktor risiko yang lebih dominan adalah higiene diri. Disarankan agar wanita lebih memperhatikan frekuensi mengganti pembalut pada saat menstruasi minimal tiga kali sehari.
Background: Short-term memory plays a role in all children's cognitive processes both in understanding the language, working on the task and problem-solving process. The speed of cognitive processes in children depend on the degree of activation of short-term memory. With stimulation that given in the form of brain-activating movements is expected to integrate short-term memory and long-term memory to generate new knowledge or expand the existing load in long-term memory. Cognitive function and academic achievement can also be influenced by the level of physical fitness. Physical fitness is very useful to support the physical capacity of children who in the end expected to improve his performance. Objective: This research was conducted to find out how big increase of short-term memory and physical fitness at the addition of Brain Gym in SSAI program at elementary school student of Inpres Pondang. Method: This research is true experimental, using two group pre and post test control group design. This research was conducted at SD Inpres Pondang, 3 times weekly for 6 weeks, at January 22, 2018 - March 05, 2018. The sample of research is 42 people divided into two groups. The Control Group in the form of SSAI program and the Treatment Group was given the addition of Brain Gym in the SSAI program. The measuring instrument used to memory span to measure short-term memory and TKJI to measure physical fitness. Results: The results of hypothesis testing using Wilcoxon test and Mann Whitney test. Wilcoxon test results showed short-term memory improvement in the treatment group significantly (p<0.05), the control group showed significant short-term memory increase (p<0.05). The result of hypothesis test shows the value of increase of physical fitness index in the treatment group significantly (p<0.05). The increase value of physical fitness index in control group significantly (p<0.05). Mann Whitney test results showed the value of span digits in the treatment group and control group with p=0.005 (p<0.05). Physical fitness value in treatment group and control group with p value = 0.091 (p>0.05). Conclusion: Statistically there is a difference in the addition of brain gymnastics to SSAI in increasing short-term memory of elementary students. Statistically there is no difference in the addition of brain gymnastics in SSAI in improving physical fitness in elementary school students.Keywords: Short term memory, physical fitness, memory span, Indonesian physical fitness test, brain gym, healthy gymnastics Indonesian children.
One of the manual matrial handling jobs is the derivative work from the top of the truck. In working the workers use a tool that enggrong which is a short-handed shovel. Due to the use of employee enggrong work with stooped posture. This work posture raises the potential for low back pain in workers. This study is a cross sectional study with a sample of 9 participants. The purpose of research is to find potential risks of low back pain based on angle trunk when workers work sent down the sand by enggrong. Angle trunk which is predicted covering: 1 angle trunk flexion, 2) angle trunk bending, and 3) angle trunk twisting. Work posture data was taken using Microsoft KinectTM 3D camera and analyzed by using Siemen Jack 3D Static Strength Prediction Program (3DSSPP) software to predict angle trunk. The result of the analysis of the 6 work postures showed that worker's frequently employed posture had the average angle trunk flexion of 61.10 ± 10.090, angle trunk bending of 19.80 ± 6.740 and angle trunk twisting of 20.00 ± 9.030. The average angle trunk flexion at 87.28% of maximal angle is a major cause risk low back pain. So that it can be summed up the potential for low back pain on sand workers. Intervention ergonomics need to prevent and reduce potential risks happened low back pain on sand workers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
