Abstract

Telah terjadi krisis identitas di dalam mata pelajaran pendidikan jasmani (penjas) di beberapa negara di dunia, termasuk Indonesia. Banyak sekolah-sekolah yang ketika mendekati masa ujian akhir mengambil kebijakan untuk meniadakan pendidikan jasmani dan menggantinya dengan mata pelajaran IPA atau Matematika tambahan. Banyak pula guru-guru penjas yang kemudian merasa kurang percaya diri, kurang yakin apakah mata pelajaran yang diampunya betul-betul bermanfaat. Padahal banyak penelitian menunjukkan bahwa penjas adalah mata pelajaran yang penting dan amat bermanfaat bagi siswa, baik secara fisiologis maupun psikologis. Manfaat-manfaat psikologis dapat dijelaskan melalui teori Neurosains maupun teori Kognitif Sosial. Bila guru-guru penjas memahami dan menyadari manfaat-manfaat penjas selain menguasai ketrampilan-ketrampilan gerak yang akan diajarkan, guru-guru tersebut akan merasa lebih percaya diri dalam mengajar penjas. Guru penjas  selain mengajarkan ketrampilan fisik juga dapat menjelaskan manfaat-manfaat ini kepada siswa, serta membina suasana yang menyenangkan dalam pendidikan jasmani. Dengan demikian para guru penjas tidak usah merasa rendah diri, dan bahkan dapat mensejajarkan diri dengan teman-teman sejawat yang mengampu mata pelajaran lain.Kata Kunci:  neurosains; teori kognitif sosialAbstract Some countries in the world including Indonesia, have been suffering from identity crisis in physical education (PE). There are many schools make absence of physical education and extend Mathematics and Physics Science. There are also many physical education teachers who are not convinced whether physical education is beneficial for their students or not. Actually, there are many research results showed that physical education is an important subject and very useful for students, physically and psychologically. Psychological benefits of physical education can be explained through Neuroscience approach or Social Cognitive approach. If the PE teachers understand and realize those benefits, beside mastering the motoric skills needed, they will be more confident in teaching their subject. They will perceive that their position is on the same level as their colleagues, who teach another subjects. They can explain those benefits to their students while teaching, and create a good climate to make their students feel happy.Keywords: neuroscience; social cognitive theory

Abstract

Penurunan aliran darah ke sel jantung, paru, otot rangka akan mengganggu dalam proses metabolisme untuk menyediakan energi yang diperlukan dalam aktifitas. Penurunan ketersediaan ATP berdampak pada penurunan kemampuan otot jantung dan otot skeletal untuk kontraksi. ATP yang menurun menyebabkan penurunan kemampuan fisik seseorang dalam melakukan kegiatan olahraga. Superoksida Dismutase sebagai antioksidan tubuh tidak mampu lagi mengimbangi jumlah radikal bebas yang ditimbulkan oleh metabolisme atau dari polutan lingkungan. Ketidakseimbangan tersebut dapat diatasi dengan antioksidan dari luar tubuh. Rosella merupakan salah satu sumber antioksidan eksogen yang diharapkan dapat mencegah aterosklerosis dan vasokonstriksi serta menyediakan nutrisi yang cukup pada proses metabolisme sel. Tujuan penelitian ini mengkaji perbedaan kemampuan fisik berenang pada tikus yang diberi teh Rosella dengan yang tidak diberi teh Rosella. Desain penelitian  pre-post test control group design. Variabel bebas dalam penelitian ini yaitu teh rosella, variabel terikat yaitu kemampuan fisik berenang. Jumlah total sampel 30 mencit. Kelompok kontrol 15 dan kelompok perlakuan 15. Bahan yang digunakan; mencit usia 1 bulan, BB minimal 10 gr, bunga rosella yang dibuat menjadi minuman teh, pakan jenis BR II. Alat yang digunakan; kandang pemeliharaan hewan coba, timbangan hewan, ember pengukur daya tahan berenang, dan alat pencatat waktu (stop watch). Analisis data menggunakan analisis varian (Anova) untuk menguji perbedaan secara keseluruhan rerata perubahan kemampuan fisik sebelum perlakuan, hari ke 7, hari ke 14, hari ke 21, hari ke 28 perlakuan dan antara kelompok kontrol dengan kelompok perlakuan. Data diolah menggunakan alat bantu komputer yaitu program  SPSS for windows version 16.00. Hasil penelitian yaitu pemberian minuman teh rosella pada mencit belum memberikan pengaruh yang nyata terhadap kemampuan fisik berenang sampai pada minggu ke-3 (p value > 0,05), tetapi memberikan kontribusi yang nyata terhadap peningkatan kemampuan fisik mencit setelah diberikan secara kontinyu sampai pada minggu ke-4 (p value = 0,029 < 0,05). Kelompok mencit tanpa perlakuan teh rosella mengalami penurunan daya tahan fisik berenang setelah minggu ke-empat. Saran dari hasil penelitian yaitu hendaknya minuman teh rosella dapat dijadikan sebagai salah satu minuman untuk meningkatkan kemampuan fisik. Untuk menyempurnakan penelitian, perlu dilakukan penelitian lanjutan tentang efek minuman  rosella dengan kajian tingkat molekul dan organela sel. Kata Kunci: metabolisme; antioksidan; teh rosella; kemampuan fisikAbstractDecreased blood flow to the heart cells, lung, skeletal muscle will interfere in the  metabolism process to provide energy required in the activity. Decreased availability of ATP impact the reduction ability of the heart muscle and skeletal muscles to contraction. ATP reduction causes a decrease in a person’s physical abilities in performing sports activities. Superoxide Dismutase as an antioxidant of the body no longer able to compensate the amount of free radicals generated by metabolism or from environmental pollutants. The imbalance can be mitigated by antioxidants from outside the body. Rosella is one source of exogenous antioxidants is expected to prevent atherosclerosis and vasoconstriction as well as providing adequate nutrition in the process of cell metabolism. The purpose of this study examines differences in physical ability to swim in rats fed with tea Rosella with those are not given. The study design pre-post test control group design. The independent variable in this research is rosella tea, the dependent variable is the physical ability to swim. Total sample is 30 mice. The control group are 15 and 15 are treatment groups. Materials used: mice aged 1 month, Body Weight least 10 grams, rosella flowers are made ​​into tea, feed type BR II. The tools used; maintenance animal cages, animal weighing, measuring bucket endurance swimming, and time recording devices (stop watch). Data analysis using analysis of variance (ANOVA) to examine differences in overall rates of change in physical ability before treatment, day 7, day 14, day 21, day 28 between treatment and control groups with treatment groups. Data processed using computer tools that SPSS for windows version 16:00. The results of rosella tea beverage delivery in mice not given a noticeable effect on the physical ability to swim up in week 3 (p value> 0.05), but provide a real contribution to improving the physical ability of mice when administered continuously until the week 4th (p value = 0.029 <0.05). Group of mice without treatment rosella tea decreased physical endurance to swim after four week. Suggestions from the research results is rosella tea beverages should be used as a beverage to enhance physical abilities. To improve research, need to do further research on the effects of rosella drinks with studies on the molecular level and cell organelles.Keywords: metabolism; antioxidant; rosella tea; physical capabilities

Abstract

Wheelchair athletes need to engage into physical activity and sports in order to keep their body functioning for activity for daily living (ADL) or for sporting actions. Sports also are a part of the rehabilitation program since it been introduced by Sir Ludwig Gutmann in England late 1940s. With the growth of sport activity in daily lives of persons with disabilities, it has been rightly perceived that disabled persons could obtain the same physical and emotional benefits from sport as their able-bodied counterparts, leading to an increased need to overcome limitations, opponents and records. The introduction of sports therapy in rehabilitation, as well as further involvement in sports depends on the severity of the injury, might lead a disabled person to either become a non-competitive athlete or a paralympic athlete. Athletes with Spinal cord injury facing problems with their thermoregulatory response. In relation to that, during exercise in the heat, paraplegic athletes demonstrates similar increase in core temperature compared with able-bodied athletes, but at a much lower metabolic rate, reflecting the decreased heat dissipation. Individuals who use wheelchairs vary widely in their level of cardiorespiratory fitness, some being seriously unfit and others are achieving levels that compare closely with those of fit able-bodied athletes. Wheelchair users also should be encouraged to use a hand-propelled rather than a motorized chair in daily life and to eat a diet that is well regulated to avoid accumulation of excess body fat.
