Abstract: Physical condition is an important role in football because with good physical condition, it will be more likely to achieve. This study aims to determine the level of physical condition of Arema players aged 16 years in Malang City in 2021. The method used in this study is descriptive quantitative which aims to provide a real picture in accordance with what is in the field about the physical condition of Arema Football Academy football players aged 16 years old in Malang in 2021. The results on leg muscle strength have an average of 44.24, speed has an average of 7.73, agility has an average of 9.91, flexibility has an average of 16.60, muscle power limbs have an average of 55.88, endurance has an average of 45.98. It can be concluded that strength (leg muscles) is in sufficient category, speed is in good category, agility is in very good category, flexibility is in very good category, leg muscle power is in good category and endurance is in good category. And the overall physical condition is in the sufficient category. Abstrak: Kondisi fisik merupakan peranan yang penting dalam sepak bola karena dengan kondisi fisik yang baik maka akan lebih berpeluang untuk berprestasi. Penelitian ini bertujuan untuk mengetahui tingkat kondisi fisik pemain arema usia 16 tahun di Kota Malang tahun 2021. Metode yang digunakan dalam penelitian ini merupakan kuantitatif deskriptif yang bertujuan untuk memberikan gambaran nyata sesuai dengan yang ada di lapangan tentang kondisi fisik pemain sepak bola Arema Football Academy umur 16 tahun di Kota Malang tahun 2021. Hasil pada kekuatan otot tungkai memiliki rata-rata 44,24, kecepatan memiliki rata-rata 7,73, kelincahan memiliki rata-rata 9,91, kelentukan memiliki rata-rata 16,60, power otot tungkai memiliki rata-rata 55,88, daya tahan memiliki rata-rata 45,98. Dapat disimpulkan bahwa kekuatan (otot tungkai) masuk kategori cukup, kecepatan masuk kategori baik, kelincahan masuk kategori baik sekali, kelentukan masuk kategori baik sekali, power otot tungkai masuk kategori baik dan daya tahan masuk kategori baik. Dan pada kondisi fisik secara keseluruhan masuk dalam kategori cukup.

Leg Muscle Power

Muscle power was defined as the combination between speed and strenght of muscle contraction and enters in the fitness components. Plyometrics exercises can be used to improve the skills of volleyball players. This study was an experimental study using research designs pre test and post test control group design. The sampling technique inthis study with a simple random sampling. The total sample of 20 person so in one group consisted of 10 person. The first group was given additional ballistic stretching on knee tuck jump exercise. The second group was given knee tuck jump exercise. Measurements of leg muscle power using vertical jump test. Normality test p > 0.05 and homogeneitytest p > 0.05. The results showed an increase in leg muscle power in first group amounted to 14.30 cm and in second group an increase of 7.70 cm. Paired samples t-test p value = 0.000 (p <0.05) in first group and p = 0.000 (p < 0.05) in second group. Test increase explosive power leg muscle after exercise in both groups using independent sample t-test obtained first group and second group where p = 0.000 (p <0.05) with an increase in the percentage of 30.95% in the first group and 16.73% in the second group. From the research done can be concluded that the addition of ballisticstretching on knee tuck jump exercise is more effective than knee tuck jump exercise in increasing explosive power leg muscle in male volleyball players Medical Faculty Of Udayana University. Keywords: muscle power, ballistic stretching, knee tuck jump, vertical jump test.

Leg Muscle Power

Background: Walking speed decreases in old age. Even though old adults regularly participate in exercise interventions, we do not know how the intervention-induced changes in physical abilities produce faster walking. The Potsdam Gait Study (POGS) will examine the effects of 10 weeks of power training and detraining on leg muscle power and, for the first time, on complete gait biomechanics, including joint kinematics, kinetics, and muscle activation in old adults with moderate mobility disability. Methods/Design: POGS is a randomized controlled trial with two arms, each crossed over, without blinding. Arm 1 starts with a 10-week control period to assess the reliability of the tests and is then crossed over to complete 25-30 training sessions over 10 weeks. Arm 2 completes 25-30 exercise sessions over 10 weeks, followed by a 10-week follow-up (detraining) period. The exercise program is designed to improve lower extremity muscle power. Main outcome measures are: muscle power, gait speed, and gait biomechanics measured at baseline and after 10 weeks of training and 10 weeks of detraining. Discussion: It is expected that power training will increase leg muscle power measured by the weight lifted and by dynamometry, and these increased abilities become expressed in joint powers measured during gait. Such favorably modified powers will underlie the increase in step length, leading ultimately to a faster walking speed. POGS will increase our basic understanding of the biomechanical mechanisms of how power training improves gait speed in old adults with moderate levels of mobility disabilities.
