Subyek dalam penelitian ini adalah siswa putra peserta extrakurikuler bola voli SMP Negeri 2 Gianyar tahun ajaran 2016/2017 sebanyak 30 orang, dibagi menjadi 2 kelompok dengan menggunakan teknik ordinal pairing, yaitu kelompok perlakuan berjumlah 15 orang dan kelompok kontrol berjumlah 15 orang. Untuk variabel daya ledak otot tungkai diukur dengan menggunakan tes vertical jump sedangkan variabel kelincahan diukur dengan tes Illinois agilty, selanjutnya data dianalisis dengan uji-t independent pada taraf signifikansi 95%, α= 0,05 dengan bantuan program SPSS 16,0. Hasil analisis daya ledak otot tungkai didapatkan nilai signifikansi 0,000 < taraf signifikansi 0,05, sehingga hipotesis loncat rintang berpengaruh terhadap daya ledak otot tungkai dapat diterima. Untuk hasil analisis kelincahan didapat nilai signifikansi 0,008 < taraf signifikansi 0,05, sehingga hipotesis loncat rintang berpengaruh terhadap kelincahan dapat diterima. Dengan demikian dapat disimpulkan bahwa loncat rintang berpengaruh terhadap peningkatan daya ledak otot tungkai dan kelincahan pada siswa putra peserta ekstrakurikuler bola voli SMP Negeri 2 Gianyar Tahun Ajaran 2016/2017. Kata Kunci : Kata kunci : Loncat rintang, daya ledak otot tungkai, kelincahan. The aim of this study is to determine the effect of hurdles jump exercise to the leg muscle explosive power and agility, this type of research is quasi experiment with the non randomized control group pretest posttest design. The subject of this study is the male students of volley ball extracurricular at SMP Negeri 2 Gianyar year 2016/2017, as many as 30 students which is divided into two groups using ordinal pairing technique, which is 15 Students as treatment group and another 15 Students as control group. As the variable of the leg muscle explosive power is measured by vertical jump test while agility variable is measured by Illinois agility test, then the data is analyzed by independent test-t at the level of significant α = 0.05 using SPSS16.0 Application. The analysis result of the leg muscle explosive power got significant value 0.000 < significant level 0.05, so the hurdles jump hypothesis has an effect to the leg muscle explosive power is acceptable. For the result of agility got significant value 0.008 < significant level 0.05, so hurdles jump hypothesis has an effect to agility is acceptable. Thus it can be concluded that hurdles jump has an effect of an increase on leg muscle explosive power and agility to the male students of volley ball extracurricular at SMP Negeri 2 Gianyar year 2016/2017 keyword : Key words: Hurdles jump, Leg muscle explosive power, Agility.

The problem in this study is that volleyball extracurricular students at SMP Negeri 6 Lubuklinggau City still have jumps and punches in the weak category, this is due to the weak power of the students' leg muscles which causes the smash to be performed less than optimal. The research objective was to determine whether there was a relationship between the explosive power of the leg muscles and the smash ability of volleyball players at SMP Negeri 6 Lubuklinggau City. The variables of this study were the leg muscle explosive power as the independent variable, and the smash ability was the dependent variable. This type of research is correlational research. This research was conducted on 14 male volleyball extracurricular students at SMP Negeri 6 Lubuklinggau City. The instrument for collecting the explosive power of the leg muscles used the vertical jump test and the smash used the smash ability test. The data analysis technique used the product moment correlation formula. The results of the study showed that there was a relationship between the leg muscle explosive power (x) and the volleyball smash ability (y), the calculation result was rxy = 0.55 from this value can be categorized as moderate. The results stated that there was a significant relationship between the explosive power of leg muscles on the smash ability of volleyball extracurricular students at SMP Negeri 6 Lubuklinggau City, this was stated based on hypothesis testing where t hit = 2.280 > t tab = 2.178.

The problem in this research is that there is still a lack of smash accuracy on male volleyball players at SMA N 8 Padang. This study aims to determine the contribution between the explosive power of the leg muscles and the flexibility of the waist muscles on the smash accuracy of male volleyball players at SMA N 8 Padang. This research is a correlational type, with a population of this study as many as 20 male players. Sampling was done by saturated sampling, so the sample in this study were 20 male volleyball players at SMA N 8 Padang. The explosive power of the leg muscles was measured by the vertical jump test and the flexibility of the waist muscles by the bridge test, then the accuracy of the volleyball smash was measured by a normal smash. The data analysis technique used was simple correlation analysis and multiple correlation. Results: There was a contribution of the leg muscle explosive power to the accuracy of the volleyball smash of 50.27%. There is a contribution of waist muscle flexibility to the accuracy of the volleyball smash of 43.43%. Then, the leg muscle explosive power and the flexibility of the waist muscles simultaneously contributed to the accuracy of the volleyball smash by 72.93%. Thus, it can be concluded that the leg muscle explosive power and flexibility of the waist contribute to the accuracy of the volleyball smash.

Background: High-physical activity, including aerobic capacity and leg muscle explosive power, can cause stress oxidative and decrease the performance of athletes. Whey protein contains essential amino acids that were beneficial to decreased malondialdehyde (MDA) levels.Objective: To analyze the effect of whey protein on MDA level, aerobic capacity, and leg muscle explosive power in basketball athletes.Materials and Methods: Randomized controlled trial using pre- and post-test design was conducted on 12 male athletes aged 16-18 years at PPLOP Central Java Basketball Club. The treatment group received 30 grams of whey protein, and the control group received 30 grams of chocolate powder as a placebo for 28 days. MDA levels were measured through Elisa methods. Aerobic capacity was measured by 20 meters sprint. Leg muscle explosive power was measured by vertical jump. Data were analyzed by an independent t-test.Results: The mean MDA levels before intervention in the whey protein group were 182.36 (±59.05), and the mean after the intervention was 171.83 (±5.46). The mean before the aerobic intervention capacity was 36.95 (±5.84), and the mean after the intervention was 49.75 (±3.53). The mean leg muscle explosive was 83.50 (±21.58), and the mean after the intervention was 87.33 (±16.68). There were no effect of whey protein on MDA levels (p>0,05), aerobic capacity (p>0,05) and leg muscle explosive power (p>0,05).Conclusion: Whey protein for 28 days had no effect on MDA levels, aerobic capacity, and leg muscle explosive power

The problem in this study is the ability to smash the volleyball athletes of SMA Negeri 1 Linggo Sari Baganti not so well. This study aims to determine the contribution of leg muscle explosive power and eye-hand coordination to the volleyball smash ability at SMA Negeri 1 Linggo Sari Baganti. The type of this research is correlational. The population in this research is all male students of class 1 and 2 of SMA Negeri 1 Linggo Sari Baganti. The sampling technique used purposive sampling. Thus the number of samples in this study was 30 people. Data were collected using measurements of all three variables. Leg muscle explosive power variables used a vertical jump test and eye-hand coordination using ball werfen unchanged, while the smash ability used the smash ability test. Data were analyzed with product correlation and followed by multiple correlation. The results showed that the explosive power of the limbs had a significant relationship with the ability to smash because it was found to count 0.576> r table 0.361. Hand-eye coordination has a significant relationship with the ability to smash because it was found to be 0.466 table 0.361. Furthermore, the explosive power of the limbs and eye-hand coordination together have a significant relationship with the ability to smash and are empirically accepted, because it is found that r count = 0.677> r table = 0.361.
