The study purpose was to prove the effectiveness of a plyometric jumping jack, countermovement jump, and tuck jump training in increasing speed, strength, and limb muscle power in adolescent males. Materials and methods. A total of 33 subjects from Santri Pondok Pesantren An-Nur 2 Al-Murtadlo Malang Regency, males, aged 18-22 years voluntarily participated in the study. The subjects were divided into 3 intervention groups, namely PJJ (n = 11, plyometric – jumping jacks), PCJ (n = 11, plyometric – countermovement jump), and PTJ (n= 11, plyometric – tuck jump). Plyometric jumping jacks, countermovement jump, and tuck jump training was conducted for 30 minutes/session, intensity 70-90% 1-RM, frequency 3x/week for 6 weeks. Measuring limb muscle power used the Jump Meter Digital (MD) Test, measuring limb muscle strength used the Back & Leg Dynamometer, and measuring speed used the 30 m running test. The data analysis technique used the Paired Sample T-Test with a significance level of 5%. Results. The results obtained were as follows: mean speed between pretest and posttest on PJJ (4.56±0.16 vs. 4.36±0.15 second, (p ≤ 0.001)), PCJ (4.61±0.15 vs. 4.54±0.14 second, (p ≤ 0.001)), PTJ (4.55±0.19 vs. 4.48±0.18 second, (p ≤ 0.001)), limb muscle strength between pretest and posttest in PJJ (111.45±18.94 vs. 139.27±20.23 kg, (p ≤ 0.001)), PCJ (117.73±21.03 vs. 129.55±19.24 kg, (p ≤ 0.001)), PTJ (115.46±17.66 vs. 125.91±18.62 kg, (p ≤ 0.001)), limb muscle power between pretest and posttest in PJJ (422.86±34.61 vs. 493.12±49.24 joule, (p ≤ 0.001)), PCJ (410.70±38.25 vs. 462.20±38.55 joule, (p ≤ 0.001)), PTJ (404.20±45.63 vs. 441.78±46.90 joule, (p ≤ 0.001)). Conclusions. Based on the results of the study, it was concluded that plyometric jumping jacks, countermovement jumps, and tuck jumps performed for 30 minutes/session, with an intensity of 70-90% 1-RM, frequency 3x/week for 6 weeks are effective in increasing limb muscle power, strength and speed.

The study purpose was to prove the effectiveness of zumba exercise on VO₂max, agility, and muscle power in students at Universitas Nusantara PGRI Kediri, East Java, Indonesia. Materials and methods. This research is a pre-experimental research design with One group Pretest-Posttest Design. A total of 15 female students from the Student Activity Unit aerobic dance exercise at Universitas Nusantara PGRI Kediri, East Java, Indonesia, aged 19–24 years, body mass index (BMI) 19.0–24.0 kg/m², normal blood pressure, resting heart rate normal, normal oxygen saturation (SpO₂), voluntarily participated in the study. Zumba exercise was carried out for 30 minutes/session with an intensity of 80% HRmax with a frequency of 3x/week for 8 weeks. The measurement of maximum oxygen volume (VO₂max) used the Multi-Stage 20-m Shuttle Run Fitness Test. The measurement of leg muscle power used the vertical jump test, while the arm muscle power was evaluated using the medicine ball throw test. Data analysis used Paired Sample t-Test with a significance level of 5%. Results. The results obtained: mean VO₂max between pretest vs post-test (26.64±4.25 vs. 30.76±4.20 mL/kg/min; p ≤ 0.001), average agility between pretest and post-test (15.76±1.24 vs. 14.55±1.27 seconds; p ≤ 0.001), average limb muscle power between pretest vs posttest (394.21±66.36 vs. 411.09±67.45 joule; p ≤ 0.001), and the average arm muscle power between pretest vs posttest (123.45±17.12 vs. 138.21±13.92 joule; p ≤ 0.001). Conclusions. Based on the results of the study, it was concluded that Zumba exercise carried out for 30 minutes/training session, with an intensity of 80% HRmax, frequency 3x/week for 8 weeks increased VO₂max, agility, and muscle power in students at Universitas Nusantara PGRI Kediri, East Java, Indonesia.

The study purpose was to prove the effectiveness of a plyometric training program in increasing explosive power and agility in professional athletes of East Java. Materials and methods. This study is a pre-experiment with a research design of One Group Pretest-Posttest. A total of 15 male athletes from athletics and swimming at the Pusat Pendidikan dan Pelatihan Olahraga Pelajar (PPLP) East Java, Indonesia, aged 15–17 years, body mass index (BMI) 18.5–24.0 kg/m², normal blood pressure, normal resting heart rate, voluntarily participated in the study. The plyometric training program (hurdle-box jumps) was carried out for 30 minutes/training session with an intensity of 80-90% HRmax with a frequency of 3x/week for six weeks. Measuring the explosive power of the horizontal leg muscles used the Standing Broad Jump Test, while measurement of the explosive power of the vertical leg muscles used the Digital Jump Meter Test. Measurement of agility used Shuttle Run Test, and explosive power and agility were measured during pre-training and six weeks post-training. Data analysis used the Paired Sample T-Test with a significance level of 5% using the Statistical Package for Social Science (SPSS) version 21 software. Results. The results of the study showed that there was a significant difference in the average increase in explosive power horizontally, vertically, and agility between pre-training vs. post-training (p ≤ 0.001). Conclusions. In general, it can be concluded that the plyometric training program (hurdle-box jumps) carried out 3x/week for six weeks effectively increases the explosive power of the horizontal leg muscles, the explosive power of the vertical leg muscles, and increases agility.
