Penelitian ini bertujuan untuk mengetahui pengaruh pelatihan medicine ball sit-up throw terhadap kekuatan otot lengan dan otot punggung. Jenis penelitian ini adalah eksperimen sungguhan dengan rancangan the randomized conrol group pretest posttest design. Sampel dalam penelitian ini adalah siswa putra SMP Negeri 4 Singaraja sebanyak 44 orang. Untuk variabel kekuatan otot lengan diukur dengan menggunakan tes push-up 60 detik sedangkan variabel kekuatan otot punggung diukur dengan instrumen tes back and leg dynamometer. Selanjutnya data dianalisis dengan uji-t independent pada taraf signifikansi lebih kecil (α) 0,05 dengan bantuan program SPSS 16,0. Berdasarkan hasil uji-t independent didapatkan hasil; (1) variabel kekuatan otot lengan dengan nilai signifikansi 0,000. (2) variabel kekuatan otot punggung dengan nilai signifikansi 0,010. Nilai signifikansi hitung lebih kecil dari nilai α (0,05), dengan demikian hipotesis penelitian “pelatihan medicine ball sit-up throw berpengaruh terhadap kekuatan otot lengan dan kekuatan otot punggung” diterima. Dengan demikian dapat disimpulkan bahwa pelatihan medicine ball sit-up throw berpengaruh signifikan terhadap kekuatan otot lengan dan kekuatan otot punggung pada siswa putra SMP Negeri 4 Singaraja tahun pelajaran 2015/2016. Disarankan bagi guru olahraga, pelatih, pembina serta atlet untuk menggunakan pelatihan medicine ball sit-up throw sebagai salah satu alternatif dalam meningkatkan kekuatan otot lengan dan kekuatan otot punggung.Kata Kunci : medicine ball sit-up throw, kekuatan otot lengan, kekuatan otot punggung This study aims to determine the effect of medicine ball sit-up throw training to arm muscle power and back muscle power. The research is quasi-experimentally in which the randomized pre-test post-test control group design. Sample were male students SMP N 4 Singaraja numbered 44 people. The instrument used for research testing arm muscle power is push-up 60 second while the instrument to test the back muscle power is back and leg dynamometer. Furthermore the data were analyzed by independent t-test at a significance level of less (α) of 0,05 with SPSS 16.0. Based on the results of independent t-test showed; (1) variable arm muscle power with significance value 0,000, (2) variable back muscle power with significance value 0,010. The significance value calculated is less than the value of α (0,05), so the hypothesis research ”medicine ball sit-up throw effect on arm muscle power and back muscle power” accepted. It can be concluded that the training medicine ball sit-up throw significant effect on the increase in arm muscle power and back muscle power on male students SMP N 4 Singaraja in the academic year of 2015/2016. For sports teachers, trainers, coaches and athletes are advised to use alternate training as medicine ball sit-up throw alternative way to increase arm muscle power and back muscle power.keyword : medicine ball sit-up throw, arm muscle power, back muscle power.

This study is correlational research that aims to find the contribution of leg muscleexplosive power to yield long jump squat style. The student sample was the son of varsity sportscoaching education Riau semester totaling 42 people. As the independent variable is theexplosive power leg muscle while dependent variable is the result of the long jump jongok style.Data (x) obtained from the test results without the leading long jump (standing board jump) toassess leg muscle explosive power while data (y) obtained from testing the long jump squat styleusing the prefix. Data were analyzed with statistical normality test is a test last lilifors alsoanalyzed the data to look for the correlation coefficient, and then proceed to test "t" after itsought the contribution. From the results of data processing for the normal distribution of dataobtained for the provision of data (x) and abnormally distributed in terms of data (y). r = 0.32,then through the test "t", t_ (count>) ttabel then there is a significant relationship between theexplosive muscle power with the outcome long jump squat style, via analysis of leg muscleexplosive power of determination have contributed 10.24% and 89 , 76% was contributed byother factors.

Metabolic Indices

The question of the proper size denominator for metabolic indices is addressed. Metabolic rate among different species is proportional to the 3/4 power of body weight, not surface area. Muscle power also varies with the 3/4 power of weight, suggesting that metabolic rate is determined mainly by muscle power. Power-to-weight ratio, specific metabolic rate, and a number of metabolic periods, including heart rate, all vary inversely with the 1/4 power of body weight. Thus the relative times required for physiological and pathological processes in different species may be estimated from the average resting heart rate for the species. There are not many small humans among athletic record holders in events involving acceleration and hill climbing, as would be expected if they had higher power-to-weight ratios. Thus the relationship between size and metabolic rate in different species should not be applied within the single species of humans. Evidence is reviewed showing that basal metabolic rate in humans is determined mainly by lean body mass.
