Abstract

This study aims to analyze the effect of the High-Intensity Interval Training (HIIT) program on improving VO₂Max in students participating in the basketball extracurricular activity at SMA Negeri 5 Malang. The training program was designed to enhance cardiorespiratory endurance, which is a crucial component in athletic performance. The study was conducted over six weeks, with a training frequency of three times a week on Mondays, Wednesdays, and Fridays, starting from October 7 to November 18, 2024. The research subjects consisted of 25 students in the experimental group. Data were collected through the Multi-Stage Fitness Test (MSFT) conducted before (pretest) and after (posttest) the training program.The results showed a significant improvement in the students' VO₂Maxafter participating in the HIIT program. The average VO₂Max value increased from 42 in the pretest to 42.7 in the posttest, with an average increase of 0.7 or equivalent to 1.66%. The median value increased from 41 to 42, while the mode value showed a significant change from 37.1 in the pretest to 51.6 in the posttest. Additionally, the standard deviation decreased from 6.43 to 6.39, indicating a more homogeneous data distribution.The paired sample t-test showed a t-value of 16.4, which is much greater than the t-table value of 1.71, with a significance value of <0.001. This proves a significant difference between the pretest and posttest results. Thus, it can be concluded that the HIIT program has a significant impact on increasing VO₂Max.This study demonstrates that HIIT is an effective and efficient training method that can be widely applied to improve cardiorespiratory endurance, particularly in young athletes. These findings provide scientific contributions to the field of sports science and can serve as a reference for sports coaches in designing evidence-based training programs. The HIIT program is not only relevant for basketball but also for other sports that require high cardiorespiratory endurance.

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.

Abstract

This study aims to investigate the effect of resistance punch training on arm muscle power, examine the effect of dumbbell punch training on arm muscle power, and determine whether there is a significant difference between the two training methods in developing arm power among kyorugi athletes of Ocean Taekwondo Club, Magelang Regency. This research employed a quantitative experimental approach using a two-group pretest–posttest design. A total of 20 athletes were selected through purposive sampling based on inclusion criteria such as training experience, belt rank, and age suitability. The participants were divided into two equal groups: a resistance punch training group and a dumbbell punch training group. Both groups underwent 16 training sessions, and arm muscle power was assessed using the medicine ball chest pass test. The results of the paired sample t-test revealed that resistance punch training had a significant effect on enhancing arm muscle power, indicated by a significance value of 0.03 (<0.05) with an improvement of 0.47%. Dumbbell punch training also produced a significant effect, with a significance value of 0.01 (<0.05) and an improvement of 0.58%. However, the independent sample t-test indicated no significant difference between the two training methods, with a significance value of 0.732 (>0.05). These results demonstrate that both training variations are effective in increasing arm muscle power, but neither method is superior. Overall, the study suggests that coaches may implement either resistance punch or dumbbell punch training as both are capable of improving arm muscle explosiveness essential for kyorugi performance. The findings may serve as a reference for designing upper-body power development programs tailored to combat sport athletes.

Abstract

Excessive body fat buildup brought on by an imbalance between energy intake and expenditure is the hallmark of obesity, which raises a number of metabolic and cardiovascular risks. The effectiveness of aerobic exercise, resistance training, and High-Intensity Interval Training (HIIT) in the management of obesity is the main emphasis of this study, which employs a literature review strategy by looking at papers from PubMed and Google Scholar published between 2015 and 2025. The analysis's findings demonstrate the effectiveness of aerobic exercise in lowering waist circumference, body fat percentage, and body weight. Resistance training is crucial for lowering visceral fat, maintaining basal metabolism, and gaining lean mass. While HIIT offers a more effective training period, it significantly reduces body fat and improves VO2peak. All things considered, the three forms of exercise have complimentary advantages and work best when combined in a planned, activity-based obesity control program.

Abstract

Long-term functional impairment following a stroke often impairs a patient's ability to do Activities of Daily Living (ADLs). In the acute and chronic stages of stroke, exercise mobilization has been widely advised as a rehabilitation technique to maximize motor recovery and avoid problems connected to immobility. The purpose of this review of the literature is to examine the data pertaining to the efficacy of exercise-based mobilization therapies in enhancing ADL independence in stroke patients. Articles with an emphasis on original research published in authorized or indexed national and international journals between 2015 and 2025 were gathered from the PubMed and Google Scholar databases. A few studies looked at mobilization exercise regimens that were started under expert supervision, including sitting, standing, transfer training, progressive gait exercise, and active or passive range of motion (ROM). Exercise mobilization significantly improves patient independence, as evidenced by higher Barthel Index values, improved mobility performance, and decreased reliance on self-care activities, according to the evaluated evidence. Early organized mobilization was also linked to shorter hospital stays, less problems such muscular weakness and joint stiffness, and better overall rehabilitation results. Excessive mobilization in unstable patients should be avoided, nevertheless, as differences in stroke severity, intervention timing, and training intensity may affect individual therapy outcomes. To sum up, exercise mobilization is a crucial and successful part of stroke rehabilitation that helps restore functional ability and boost independence in ADL. To maximize healing and improve quality of life after a stroke, a progressive exercise program administered early and safely by trained rehabilitation professionals is advised.
