Abstract

This study aims to analyze the effect of Body Mass Index (BMI) on the physical condition of karate athletes at the Riau Province Special Sports School. The physical conditions measured include arm and abdominal muscle strength, endurance, agility, flexibility, and leg muscle power. The research method used a quantitative approach with a correlational design. The sample consisted of 9 active karate athletes (5 female and 4 male) selected through purposive sampling. Data were collected through BMI measurements and a series of physical fitness tests such as push-ups, sit-ups, beep tests, Illinois Agility Runs, sit and reach tests, and standing board jumps. Descriptive analysis results showed that 89% of athletes had a normal BMI, while 11% were underweight, with no overweight or obese athletes. There was a significant relationship between BMI and flexibility (p=0.032; r=0.711), indicating that athletes with normal BMI had better flexibility than underweight athletes. Agility showed a positive but insignificant relationship with BMI (p=0.429; r=0.303). Endurance, arm and abdominal muscle strength, and leg muscle power did not show a significant relationship with BMI. In conclusion, BMI is an important indicator in supporting athletes' flexibility, but it does not directly affect other aspects of physical fitness. Monitoring BMI and holistic training programs are recommended for optimizing karate athletes' performance.

Abstract

Penelitian ini bertujuan menganalisis pengaruh latihan swim band danpush-up terhadap peningkatan kekuatan otot lengan serta kecepatanrenang 50 meter gaya dada pada perenang pemula. Metode yang digunakan adalah eksperimen semu dengan desain pretest-posttest control group. Sampel terdiri atas 20 perenang pemula berusia 13–16 tahun yang dipilih secara purposive sampling dan dibagi menjadi kelompok eksperimen(latihan swim band dan push-up) serta kelompok kontrol (latihan rutin). Program latihan dilaksanakan selama 6 minggu, 3 kali per minggu. Pengukuran kekuatan otot lengan menggunakan tes push-up 1 menit, sedangkan kecepatan renang diukur melalui uji waktu 50 meter gaya dada. Analisis data menggunakan uji t berpasangan dan uji t independen padataraf signifikansi p < 0,05. Hasil menunjukkan adanya peningkatansignifikan kekuatan otot lengan dan kecepatan renang pada kelompokeksperimen dibandingkan kontrol. Dengan demikian, latihan swim band danpush-up terbukti efektif meningkatkan kekuatan otot lengan dan performarenang gaya dada perenang pemula.

Abstract

In the Handball course for the 2021 cohort, students were found to have suboptimal performance, particularly in basic skills such as dribbling. This study aims to examine the effect of dribbling training (X) on handball basic skills (Y). The research employed an experimental method with a one-group pretest–posttest design. The population consisted of 43 PORKES students from the 2021 class, and purposive sampling was applied to include only male participants, resulting in a sample of 12 students. The research instrument used a 40-meter dribbling test developed by Susanto. Data analysis used an independent t-test with a significance level of α = 0.05. The results indicated a significant improvement in students’ dribbling performance, with an average time reduction of 7.19 seconds, from 19.27 seconds in the pre-test to 12.08 seconds in the post-test. Statistical analysis showed tcount = 24.623 > ttable = 1.796, confirming a significant effect of the dribbling training. It can be concluded that dribbling training has a positive and significant effect on improving basic handball skills among Sports and Health Education students at Pasir Pengaraian University.
