Latar belakang: Taekwondo merupakan bela diri yang banyak menggunakan anggota gerak bawah terutama pergelangan kaki sehingga sering terjadi fungsional ankle instabilitas (FAI). FAI terjadi akibat adanya gangguan dari postural kontrol, keseimbangan dinamis dan fungsi otot. Salah satu latihan yang dapat dipergunakan adalah star excursion balance exercise, namun masih ada kekurangan dalam kontrol postural akibat tidak terjadi aktivasi otot core untuk pembentukan postural stabilisasi. Tujuan: Untuk membuktikan penambahan core stability pada star excursion balance exercise lebih meningkatkan keseimbangan dinamis dan menurunkan fungsional ankle instabilitas daripada star excursion balance exercise pada bela diri taekwondo. Metode: Rancangan penelitian ini adalah randomized pretest-postest control group design, Kelompok 1 mendapatkan star excursion balance exercise dan Kelompok 2 mendapatkan core stability dan star excursion balance exercise. Fungsional ankle instabilitas diukur menggunakan cumberland ankle instability tool (CAIT) dan keseimbangan dinamis menggunakan star excursion balance test (SEBT). Dilakukan 3 kali seminggu selama 6 minggu. Hasil: Peningkatan SEBT sebelum pelatihan pada Kelompok 1 sebesar 86,4±6,3 cm, setelah pelatihan sebesar 92,3±6,7cm dan pada Kelompok 2 sebelum sebesar 86,2±6,1 cm, setelah pelatihan sebesar 96,7±7,9 cm. Penurunan fungsional ankle instabilitas dari peningkatan nilai CAIT sebelum pelatihan pada Kelompok 1 sebesar 20,4±1,8, setelah pelatihan sebesar 23,4±2,1 dan pada Kelompok 2 sebelum sebesar 20,3±2,8, setelah pelatihan sebesar 25,0±1,9. Perbedaan peningkatan keseimbangan dinamis pada Kelompok 1 dan 2 bermakna (p<0,05). Perbedaan penurunan FAI pada Kelompok 1 dan 2 bermakna (p<0,05). Kesimpulan: Penambahan core stability pada star excursion balance exercise lebih meningkatkan keseimbangan dinamis dan menurunkan fungsional ankle instabilitas daripada star excursion balance exercise pada bela diri taekwondo. Kata kunci: fungsional ankle instabilitas, keseimbangan dinamis, star excursion balance exercise, core stability.
Individual that greater use of information and communication technologies such as computer, smartphone, or other media has the tendency failure of body postures. Laptop usage has been associated with adolescent neck pain, with daily use of computers exceeding 2-3 hours as a threshold to forward head posture. Forward head posture can affect the result of reducing cervical alignment and mobility of the neck. There are exercises that intention to improving the cervical alignment and mobility, particularly sling-based manual therapy and stabilization exercise. A sling device provide the research subject with optimal loading of each target segment, in actual neutral position, and an environment for exercise in a closed kinetic chain. Spinal mobilization techniques used in manual spinal treatment activate the descending pathway from the peritubular gray region (PAG) of the midbrain. Moreover, stabilization exercise affect postural control through concurrent contractions of the agonist and antagonist muscles to improving cervical alignment and mobility. Key Words: Sling; Manual Therapy; Stabilization Exercise; Cervical Alignment; Cervical Mobility; Forward Head Posture
Introduction: Kyphosis is generally defined as a disease that occurs in the area of the vertebrae or the human spine which causes a hunched posture. As for some musculoskeletal complaints caused by kyphosis, including changes in body posture that bends forward so that it affects appearance, pain is felt in the spinal area, muscles get tired easily, and tightness in the back area, which in the most severe conditions kyphosis can cause problems in the respiratory tract and other organs. The cause of kyphosis is caused by several factors, namely body mass index, workload, disease scheurman,and birth defects. This study aims to determine whether there is a relationship between Body Mass Index and Physical Activity with the Incidence of Kyphosis in Physiotherapy Students at the Faculty of Medicine, Udayana University. Method: This research is a type of descriptive analytic research approach cross-sectional, using the total sampling technique, the number of subjects was 64 physiotherapy students who met the exclusion and inclusion criteria. Data was taken by measuring body mass index using the BMI formula, using global physical activity questionnaire (GPAQ) to measure physical activity, flexicurve as a measure of the degree of kyphosis.
Introduction: Limited activities will increase the risk of sedentary activity, so that it will become a new problem. Exercise is an effort to reduce sedentary activity and reduce boredom, maintain health, and increase the immune system. The right kind of exercise will have a good and bad impact. Therefore, this study aims to look at exercise with a target heart rate, safety and effectiveness, and reduce sedentary effects during the Covid-19 pandemic. Methods: The data used has been through literature studies obtained from research articles including PubMed, ScienceDirect, and Google Scholar. With keywords, including COVID-19 pandemic, sedentary effects, exercise, target heart rate. The data analysis technique used is argumentative, descriptive analysis. Results: Based on the literature view, the writer found ten related articles. This study provides evidence of the effect of exercise with target heart rate both safety and effectiveness for reducing sedentary effect. This article explained that it knows the exercise heart rate that the heart wants to reach and can be accepted by the heart, reduces lipid, increases the immune response, improves fitness and heart health. Conclusion: Exercises can use the target heart rate to provide an overview of the range of training zones you want to achieve and provide safety and effectiveness in exercising, especially the cardiovascular system.
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.
