Penelitian ini bertujuan untuk mengetahui pengaruh latihan aerobik terhadap penurunan indeks massa tubuh dan penurunan ketebalan lemak subkutan.Penelitian ini adalah penelitian Experiment yang hanya menggunakan satu kelompok perlakuan tanpa menggunakan kelompok kontrol. Penelitian dilakukan selama 12 minggu dengan frekuensi latihan 3 kali seminggu dengan durasi latihan 30 menit. Adapun latihan aerobik yang diberikan adalah jogging. dengan standar training zone 60% - 80% kali denyut nadi maksimal (DNM). Desain penelitian menggunakan one group pretest-postest dan menunjukkan hasil yang signifikan dengan aktifitas latihan aerobik. Pengambilan data dilakukan sebelum dan sesudah latihan.Populasi dalam penelitian ini adalah remaja putra atau siswa SMAN 3 Takalar, sedangkan sampel dalam penelitian ini berjumlah 25 orang yang ditentukan dengan menggunakan teknik purposive sampling.Berdasarkan hasil penelitian dan pembahasan, dapat ditarik kesimpulan bahwa terdapat pengaruh yang signifikan latihan aerobik terhadap penurunan indeks massa tubuh dan ketebalan lemak subkutan. Indeks massa tubuh diperoleh thitung sebesar 13,981 dan nilal p=0.000 (p< 0,05). Sementara lemak tubuh diperoleh thitung sebesar 13,063 dan nilai p= 0,000 (p<0,05). Ini membuktikan bahwa ada pengaruh yang signifikan latihan aerobik terhadap penurunan indeks massa tubuh dan penurunan ketebalan lemak subkutan.
The appropriate genetic potential of an athlete or prospective athlete determines the development of their future performance and achievement and reduces the risk of pathological conditions such as overtraining. This study aimed to determine the genotype variation thought to play a role in differences in exercise results and explosive power performance, namely the ACE gene. The research method used a cross-sectional design to describe the relationship between a factor and its effects on how genetic mutation variations play a role in an athlete's physical performance by involving 54 male and female badminton athletes with an average age of 18 years. The study was conducted by analysing the development of badminton skills with the same exercise routine, then being given an explosive power test in the form of a vertical jump through the Lewis nomogram assessment. The initial test was in the first month, and the second test was after six months. The results showed significant differences between the groups with variation II, ID and DD genotypes of the ACE gene. The DD genotype group showed better training adaptation in the explosive power test than genotype II and ID with a significant value (P<0.05). This study concludes that athletes with genotype DD variations adapt better to explosive power training than athletes with genotype II and ID. Athletes with genetic mutations II and ID in the ACE gene are more suitable for badminton sports requiring complex movement abilities and skills, which require good anaerobic and aerobic abilities.
Ada tiga pondasi utama yang penting dan wajib dipedomani untuk mencapai target prestasi atlet yaitu, potensi genetik, kecukupan nutrisi dan latihan terprogram. Nutrisi yang tepat akan sangat membantu penampilan optimal atlet saat bertanding. Selain itu nutrisi ini dibutuhkan pula pada kerja biologik tubuh, untuk penyediaan energi tubuh pada saat seorang atlet melakukan berbagai aktivitas fisik, misalnya pada saat latihan, bertanding dan saat pemulihan. Nutrisi juga dibutuhkan untuk memperbaiki atau mengganti sel tubuh yang rusak. Banyak pelatih atau atlet yang menganggap bahwa asupan nutrisi pada atlet sama saja dengan yang bukan atlet. Kenyataannya tidak demikian, asupan nutrisi pada atlet disiapkan berdasarkan pengetahuan tentang dominasi energi yang akan digunakan, peran sumber nutrisi tertentu pada proses penyediaan energi. Dalam hal ini termasuk pula tentang pemberian suplemen dan usaha khusus berupa modifikasi yang dilakukan terhadap asupan nutrisi pada waktu tertentu, dalam upaya meningkatkan kinerja atlet. dari workshop yang telah dilaksanakan ini para atlet bisa mencapai prestasi maksimal melalui pengaturan makan yang tepat dan variatif.
The main problem is the decreased level of fitness and concentration. The reason is technological advances so that a person does not need the energy to carry out his activities and can be recorded and stored in an online database. The author provides a community service solution with low-impact aerobic dance to increase cardiovascular endurance and concentration in 36 female students aged 18-20 years. The pretest at the first meeting, low-impact aerobic dance material is 30 minutes long, 3 times per week is carried out for 6 weeks, and ends with a posttest. The pretest and posttests used the Multi-Stage 20m Shuttle Run Fitness Test for cardiovascular endurance and the Grid Concentration Test for concentration. There was an average increase in cardiovascular endurance of 3.34 and concentration of 2.11. This dedication is necessary for increasing cardiovascular endurance and concentration so that daily activities do not experience fatigue and still have energy reserves to carry out other activities and be more focused.
