Abstract

Jumping ability is one of the main components in a volleyball game, especially during smash, block, and serve. Optimal jump height provides a competitive advantage, both in attack and defense. This study aims to determine the effect of pliometric depth jump training on the jump height of volleyball extracurricular participants at SMAN 5 Malang in the 2024/2025 school year. Pliometric depth jump training was chosen because it was proven to have an effect in increasing leg muscle strength, and explosive power. This study used an experimental method with a one group pre-test-post-test design. The population in this study were 10th grade students who were members of volleyball extracurricular activities at SMAN 5 Malang, with a total sample of 25 students. The training program was carried out for six weeks with a frequency of three times per week on Monday, Wednesday, Friday. The vertical jump test was used to measure jump height before and after the training program. The data obtained were analyzed using paired sample t-test with the help of SPSS software. The results showed an increase in jump height after the subject received treatment in the form of pliometric depth jump training. The average increase in jump height was 3-5 cm. The statistical test resulted in a significance value of <0.001, which indicates the effect of pliometric depth jump training on the vertical jump ability of volleyball extracurricular participants of SMAN 5 Malang. In addition, the results of this study indicate that pliometric depth jump training can also improve athletes' body coordination, balance, and reaction time, which are important elements in volleyball. Based on the results of the study, it can be concluded that the depth jump pliometric training program is effective for increasing the jump height of volleyball extracurricular participants of SMAN 5 Malang.

Abstract

High inflammation in obesity is a serious problem for improving the quality of human resources. High inflammation in obesity conditions will interfere with health metabolism, thus having an impact on the occurrence of complications in obesity. Regular physical exercise is believed to be a strategic method for individuals who are obese. The purpose of this study is to prove the combination exercise on reducing inflammation in obesity. A total of 20 obese women with a BMI of ≥25 kg/m2 were divided into 2 groups, namely the control group (K1; n = 10), the combination exercise intervention group (K2; n = 10). Exercise is done at moderate intensity (aerobic exercise 60-70% HRmax and strength training 60-70% 1-RM), on aerobic exercise for 40 minutes and strength training as many as 4-6 sets, 10-15 reps, with a frequency of 5x/week, for 4 weeks. Inflammatory levels use the biomarker IL-1β. Inflammatory levels were measured at the time of pretest and posttest using the ELIS method. The Paired Sample T-Test showed no difference in the average inflammatory level between the pretest and the posttest in K1 (22.45 ± 7.15 vs 22.72 ± 6.87 ng/mL; p= 0.867), and in K2 there was a significant difference (23.86 ± 10.18 vs 16.27 ± 3.60 ng/mL; p= 0.037). It can be concluded that with 4 weeks of moderate-intensity combination exercise, it is proven to reduce inflammation levels in obese women.

Abstract

Training is aimed at improving an athlete's abilities in a methodical and consistent manner to demonstrate their peak performance. This specifically refers to training focused on passing. Small Sided Games serve as a training technique used in futsal that closely mimics a real match scenario, with modifications in aspects such as rules, playing area, and number of participants. These games revolve around skill development and conditioning, serving as game-oriented drills. They offer an efficient way to train that addresses technique, strategy, and physical endurance all at once. The method used in this study was a quasi-experimental study with two groups, namely, experimental group 1 which was given small-sided games training and experimental group 2 which was given rondo training which was selected randomly. The population was studied 25 players with 22 players selected as research samples through purposive sampling techniques. This study shows that there are changes resulting from both exercises on the passing accuracy of the players. The conclusion is that small sided games and rondo training both have an influence on passing in each group.

Abstract

This study aims to analyze the effect of short-term combination training for 4 weeks in reducing leptin levels in obese women. The method used is a true experimental with a randomized pretest-posttest control group design, involving 14 obese female subjects who were divided into two groups: control (K1) and combination training (K2). The combination training consisted of endurance training (treadmill) and resistance with moderate intensity (60-70% 1-RM) which was done 5 times per week for 4 weeks. The results showed a significant decrease in leptin levels in the K2 group compared to K1, which actually showed a slight increase in leptin. The decrease in leptin levels in K2 was associated with a decrease in fat mass and body mass index (BMI), accompanied by an increase in muscle mass. Combination training has a significant effect on reducing leptin through increased energy expenditure and reduced adiposity. Although this study showed positive results, there are still limitations in controlling external factors such as stress levels that may affect leptin levels. Further research is recommended to consider these variables so that the results are more comprehensive.

Abstract

Obesity is closely associated with chronic low-grade inflammation, which plays an important role in the development of various comorbidities and its prevalence continues to increase year by year. In obese individuals, IL-10 levels tend to be lower which is associated with increased insulin resistance, hyperinsulinemia, and increased risk of metabolic dysfunction, including type 2 diabetes, exacerbated by obstructive sleep apnea, contributing to systemic inflammation and cardiovascular risk. Physical exercise is believed to have beneficial effects on obesity and suppress inflammation followed by a decrease in fat mass and an increase in muscle mass. The aim of this study was to prove that combined aerobic and resistance training with moderate intensity increases anti-inflammatory cytokine production in obese women. This study used a true experimental method with a pretest-posttest control group design. 16 obese women aged between 20 and 30 years were divided into two groups: control group (K1; n=8), and combination exercise group (K2; n=8). The exercise intervention was moderate intensity combination exercise (60%-70% Hrmax; 60-70% 1-RM), with a frequency of 5x/week for 8 weeks. With a detection range of 0.78-50 pg/mL and sensitivity level of 0.49 pg/mL, inflammation levels were measured both at pretest and posttest using ELISA kit method. Data with a significant level (p>0.05) were evaluated with the Paired Samples T-test. The results of the analysis of IL-10 levels between pretest and posttest in K1 (1.74 ± 0.13 vs 1.75 ± 0.19 ng/mL; p = 0.951), and K2 (1.75 ± 0.19 vs 2.41 ± 0.72 ng/mL; p = 0.016). This study showed that obese women had higher levels of IL-10 after 8 weeks of combined exercise.
