Speed and power are the most important physical components in badminton with the current rally point system. The purpose of this study was to determine the effect of badminton shadow training on power and speed. This research used experimental research with randomized group pre-test and post-test design. The subjects of this study were male students IKOR unesa 2018 class which were randomly divided into experimental group 1 (K1) and experimental group 2 (K2) consisting of 10 people per group. K1 group was given badminton shadow training with 1: 1 interval training method and K2 group with 1: ½ interval training method with 15 seconds training time. The power test is performed using jump MD and the speed test is carried out with a 30 Meter sprint test. Paired t test results were significant (p <0.05) on power (p = 0.035) and speed (p = 0.006) at K1, whereas at K2 were also significant at power (p = 0,000) and speed (p = 0.014). Independent sample t test results were not significant at the power (p = 0.190), while the speed was also not significant (p = 0.165). In conclusion, badminton shadow training can increase power and speed with both 1:1 or 1: ½ interval training ratios. Shadow badminton training with 1: ½ interval training is more to increase power and speed because on average the results are better than shadow badminton training with 1:1 interval training.
Olahraga dapat meningkatkan imun tubuh dan mengurangi resiko infeksi terhadap penyakit. Dengan meningkatnya imun tubuh, maka efek kesehatan akibat penyakit yang menyerang dapat dikurangi. Penelitian ini bertujuan untuk menghasilkan buku saku pencegahan infeksi Covid-19 melalui olahraga. Model penelitian pengembangan ini menggunakan (Research and Development) Analysis, Design, Development, Implementasi, Evaluation (ADDIE). Instrument penelitian menggunakan angket dan wawancara ahli materi (olahraga dan kesehatan) dan ahli bahasa. Hasil penelitian menunjukkan bahwa buku saku yang dikembangkan layak digunakan berdasarkan penilaian 6 orang ahli terhadap komponen materi, bahasa dan tampilan. Rata-rata ahli memberikan nilai sangat baik pada komponen isi (3,60) dan Bahasa (3,75), sedangkan pada komponen tampilan rata-rata nilainya baik (3,52). Pada respon mahasiswa didapatkan nilai persentase jawaban “Ya” sebesar 91,72% dengan kategori baik sehingga buku saku layak untuk digunakan.
This study aims to determine the kinematics of the men's 50 and 100 meter freestyle swimming athletes. Research method uses quantitative descriptive with 50 meter swimmers and 100 meter freestyle men at the 2019 IOAC championship. Instrument used was a Sony Rx-10Mark IV camera placed in the highest stands at a distance of 25 m in a 50-meter pool. Video results analyzed using the Kinovea 0.8.27 software by calculating the SF,SV,SR, and SL. The results showed that the average number of a 50meter had an SF of 13.06,SV of 1.89 m.s-1,SR of 59.08 cycles.min-1, and SL of 1.92 m.cycle-1. The 100 meter number, the average SF value is 11.8 at a distance of 50-meter and 12.08 at 100 meter. In comparison, the SV average is 1.73 m.s-1 at a distance of 50 and 1.72 m.s-1 at a distance of 100-meter. SR the average is 46.35 cycles.min-1 distance of 50 meter and 50, 2 100 m distance. SL the average is 2.25 m.cycle-1 distance of 50-meter and 2.08 distance of 100-meter. Conclusion, are differences in kinematics of swimming between the men's 50 meter and 100 meter freestyle in SV and SR,while those in SF and SL tend to be the same.
Tujuan dari penelitian ini adalah untuk mengetahui efek pemberian jus semangka kuning terhadap penurunan tekanan darah, kadar asam laktat dan peningkatan daya tahan anaerobic setelah aktivitas anaerobik. Jenis penelitian ini adalah penelitian eksperimen dengan desain randomized group pretest and posttest design. Subyek penelitian menggunakan atlet bulutangkis putra PBSI Jombang yang dibagi secara acak ke dalam kelompok control (K1) dan kelompok perlakuan (K2) yang masing- masing terdiri dari 18 orang coba. Kelompok kontrol diberikan sirup tanpa gula sebanyak 350 ml, sedangkan kelompok perlakuan diberikan jus semangka sebanyak 350 ml. Aktivitas anaerobic dilakukan dengan lari sprint 300 meter. Pengukuran tekanan darah, asam laktat dan daya tahan dilakukan 3 kali (pre, post1 dan post 2). Hasil uji t 2 sampel bebas menunjukkan terdapat perbedaan yang signifikan pada variable tekanan darah sistole (TDS) nilai p = 0,023 dengan rerata K1 129,11±6,55 Mm/Hg dan K2 125,67±4,77 Mm/Hg, tekanan darah diastole (TDD) nilai p = 0,019 dengan rerata K1 78,72±4,61 Mm/Hg dan K2 76,22±4,86 Mm/Hg, kadar asam laktat nilai p = 0,006 dengan rerata K1 4,59±0,97 mMol/L dan K2 2,81±0,73 mMol/L serta daya tahan anaerobic nilai p = 0,012 dengan rerata K1 7,13±0,74 watt/sec dan K2 6,08±0,80 watt/sec. Hasil tersebut dapat disimpulkan bahwa pemberian jus semangka kuning (citrullus vulgaris schard) dapat menurunkan tekanan darah dan kadar asam laktat serta meningkatkan daya tahan anaerobik setelah aktivitas anaerobik.
The purpose of this study is to analyze the effects of cardio exercise and tabata method on body weight, body fat, and physical fitness. This study applied experimental design with pretest and posttest. A total of 27 respondents were all males and had BMI over 25.0 (overweight and obese). They were then divided into 3 groups: control (K1), cardio group (K2) and Tabata group (K3), each consisting of 9 individuals. K1 did not receive any intervention. While K2 and K3 were received six-weeks interventions, three times per week. K2 performed jogging and skipping training at 55% -70% HRmax during 40-minutes. While K3 performed squat trust and skipping 8 sets at 90%-95% HRmax. There were significant differences between groups for all body composition measures. In conclusion, Tabata method represents an effective way in reducing body weight and body fat, but it is no better than cardio exercise in improving physical fitness.
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.
