Abstract

Purpose: Intermittent Fasting is currently a supporting strategy for weight loss that is widely used because indirectly energy needs are obtained from burning fat in the body. The purpose of this study was to evaluate the effect of the combination of Intermittent Fasting with physical activity, researchers used the type of brisk walk exercise in the weight loss program and changes in body composition in each individual. Materials and Methods: The research method was carried out by conducting an exercise program for 12 periods with measurements of body weight, body mass index, body fat, body water, and visceral fat as the main parameters. Result: The results showed that the combination of Intermittent Fasting with physical activity, especially brisk walking, had a significant positive impact on weight loss and body composition regulation. Conclusion: It can be concluded in this study that the combination method of Intermittent Fasting with physical activity is quite good in reducing body weight, body mass index, body fat, body water, and visceral fat.

Abstract

Purpose: This study aims to analyze the effect of speed-endurance training on increasing aerobic capacity (VO₂max) among students participating in extracurricular futsal activities. Materials and Methods: This study involved 35 male futsal extracurricular students divided into an experimental group (n = 20; age 14.70 ± 0.47 years, height 159.20 ± 7.57 cm, weight 53.25 ± 7.61 kg, BMI 20.02 ± 1.59) and a control group (n = 15; age 14.60 ± 0.51 years, height 160.20 ± 2.43 cm, weight 53.80 ± 5.24 kg, BMI 20.93 ± 1.56). The experimental group underwent four weeks of Speed Endurance Soccer Training (SEST), while the control group participated in regular futsal training. Aerobic endurance (VO₂max) was measured using the beep test during pretest and posttest. Statistical analysis using SPSS 27 revealed normally distributed residuals (Shapiro–Wilk p = 0.053) but unequal variances (Levene's test p < 0.001); therefore, Quade's nonparametric ANCOVA with the pretest as a covariate was applied, followed by pairwise comparisons. Significance was set at p < .05. Result: All variables were normally distributed (Shapiro–Wilk p = 0.053), but the homogeneity assumption was violated (Levene’s test p < .001). Therefore, the data were analyzed using Quade’s nonparametric ANCOVA, which showed a significant group effect after controlling for the pretest scores (F(1,33) = 46.70, p < .001). Pairwise comparison confirmed that the experimental group achieved significantly higher posttest VO₂max scores than the control group (t(33) = −6.83, p < .001). Conclusion: Speed-endurance training effectively improved students' aerobic capacity and proved to be a practical, efficient method that can be readily implemented in school-based futsal training programs.
