Abstract

Pukulan smash merupakan salah satu teknik pukulan menyerang dalam permainan bulutangkis. Latihan pengulangan seperti bayangan, drilling dan strokes dapat meningkatkan kecepatan dan koordinasi gerakan. Namun, latihan kombinasi bayangan dengan drilling dan strokes dalam meningkatkan kecepatan reaksi dan ketepatan smash masih belum pernah dijelaskan. Tujuan penelitian ini untuk membuktikan latihan kombinasi bayangan dengan drilling (P1) lebih meningkatkan kecepatan reaksi dan ketepatan smash dibandingkan latihan kombinasi bayangan dengan strokes (P2). Penelitian ini termasuk eksperimental lapangan, subjek 18 orang dibagi secara random menjadi dua kelompok. Kedua kelompok diberi perlakuan 6 minggu dengan frekuensi latihan 4 kali seminggu. Tes kecepatan reaksi menggunakan alat whole body reaction dan tes ketepatan smash menggunakan tes kemampuan ketepatan smash. Hasil uji t berpasangan pada kecepatan reaksi P1 0,277±0,08 dan P2 0,270±0,629, ketepatan smash P1 11,25±3,732 dan P2 8,625±2,446, menunjukkan adanya peningkatan kemampuan kecepatan reaksi dan ketepatan smash yang signifikan. Hasil uji t independent perubahan pretest ke posttest pada P1 dan P2 adalah 0,832 dan 0,118, maka terdapat perbedaan perubahan peningkatan kemampuan yang tidak signifikan. Kesimpulan penelitian ini adalah latihan kombinasi bayangan dengan drilling dan latihan kombinasi bayangan dengan strokes keduanya dapat meningkatkan kemampuan kecepatan reaksi dan ketepatan smash bulutangkis.

Abstract

Lari sprint atau lari jarak pendek adalah salah satu nomor dalam atletik yang paling bergengsi, pelarinya disebut Sprinter. NMT adalah tehnik aplikasi yang menggunakan elastic adhesif tape yang memberikan kemampuan peningkatan fungsional otot, dan stimulasi sistem saraf. Tujuan penelitian ini, untuk mengetahui pengaruh neuromuscular taping terhadap kekuatan otot, fleksibilitas otot dan waktu tempuh sprinter 100 meter. Penelitian ini menggunakan metode pre test-post test with control grup design dengan total sampel berjumlah 13 orang dengan rentang usia atlet 15-19 tahun, pada tanggal 4-5 Agustus 2016 di GOR Gresik. Metode 1 kelompok dengan 2 perlakuan yaitu perlakuan I sebelum pemberian NMT dilakukan pengukuran kekuatan otot, fleksibilitas otot, dan waktu tempuh berlari 100 meter dan sesudah pemberian NMT dilakukan pengukuran kembali, perlakuan 2 sebagai kelompok kontrol dilakukan tanpa pemberian NMT dilakukan pengukuran kekuatan otot, fleksibilitas otot, dan waktu tempuh berlari 100 meter. Hasil penelitian menunjukkan pada perlakuan 1 kekuatan otot gastrocnemius dengan peningkatan rerata 11,38±7,83kg, nilai p=0,000, fleksibilitas nilai p=0,003 (dorsofleksi), p=0,013 (plantarfleksi) dengan peningkatan rerata 3,46±4,27 derajat, dan pemendekan waktu tempuh dengan nilai p=0-001, pada perlakuan 2 kekuatan otot gastrocnemius dengan penurunan rerata 2,12±2,43kg, nilai p=0,009, fleksibilitas nilai p=1,000 (dorsofleksi), p=0,165 (plantarfleksi) dengan peningkatan rerata 0,77±1,88 derajat, dan waktu tempuh terjadi perpanjangan waktu dengan nilai p=0-001 . Pemberian NMT pada sprinter memberikan hasil yang lebih baik dalam peningkatan kekuatan otot, fleksibilitas otot dan memperpendek waktu tempuh.

Abstract

An achievement in sport is one of the benchmarks of success of every athlete. One of the causes of the performance degradation is fatigue due to the formation of lactic acid. Supplements are proved to improve the performance in athletes. The purpose of this study was to determine the effect of citrulline supplementation on lactic acid levels and oxygen saturation on submaximal physical activity. Fatigue can be seen from lactic acid levels in subjects who have performed physical activity. This research method used randomized group pretest postest group design. The subjects used were male students of pencak silat airlangga university, and divided into two groups. The first group was given placebo and the second group was given citrulline. Each group was given the same treatment of three minutes of submaximal physical activity using an ergocycle. Before and after doing the activity the blood lactic acid and oxygen saturation of the subject was checked. The result of the data showed that lactic acid and oxygen saturation in both groups had p<0,05. Citrulline supplementation had effect on lactic acid and oxygen saturation. The results of the research showed that the group given with citrulline had significant effect on lactic acid and oxygen saturation before and after treatment.

Abstract

The eccentric contraction has been proven to improve Glut-1 expression in muscle and fasting glucose levels in mice. The same eccentric contraction occurs in human being when walking or running while wearing high heels. Innovation on the eccentric contraction with high heels can be done by using a specific shoe insole. The design of the rear insole is made thicker than the front. The purpose of this study was to determine the effects of insole use specified for eccentric activities on daily work shoes on the skeletal muscle damage after wearing the specified insole. Skeletal muscle damage was measured based on sTnI level. This was experimental study with pretest-posttest design. The subjects involved were non-diabetic woman workers in Faculty of Medicine of Universitas Airlangga, and were divided into two groups. Each group represented group members who wore 5-degree and 10-degree insoles respectively. The angle used for the shoe insoles were 5° and 10° respectively. These insoles were worn on weekdays for one week. Blood was taken one day after the subjects stop wearing the insoles. Data results showed that the levels of fasting blood glucose (FBG) of subjects who wore the 10-degree insole had a value of p<0.05. The use of insole lead to decreased levels of fasting blood glucose (FBG). This study found that the sTnI levels in the 5-degree and 10-degree insole groups had no significant effect on troponin I skeletal muscle levels before and after treatment.

Abstract

Diabetes is a metabolic syndrome which characterized with insulin insensitivity, lack of GLUT-4 membrane presentation and ATP deficiency. ATP is needed for substrate phosphorylation, signalling pathways, protein translation and cellular survival. Since GLUT-1 was discovered as alternative glucose transporter on muscle membrane, some studies started to investigate it more. This study aimed to investigate GLUT-1 presentation on diabetes muscle membrane of rat model in time. Diabetes was obtained from a 50 mg/kg B.W of streptozotocin intra peritoneal injection on rat. We found that GLUT-1 presentation increased significantly in time of diabetic stages. It correlated negatively with GLUT-4 presentation and mortality. Eccentric downhill running on diabetic rat model improved GLUT-1 presentation and blood glucose level. It was promising for diabetes management therapy at the future.
