This study aims to demonstrate the effect of a running and jumping game model in improving physical motor impairments in children with intellectual disabilities. A pre-experimental design method was used, involving 15 male children aged 11-12 years with intellectual disabilities, who were selected through purposive sampling. The running and jumping game model was conducted for 30 minutes per session, with moderate intensity (60-70% HRmax), three times a week for four weeks. Data collection involved measuring motor skill development, namely running speed and jump height, between pretest and posttest using a 40-meter run test and vertical jump test. Data analysis was conducted using a paired sample t-test with a 5% confidence level. The results showed a significant difference in running speed between pretest and posttest (8.98±0.07 vs. 7.66±0.09 seconds; p=0.001). Similarly, jump height analysis showed a significant difference between the pretest and posttest (21.57±0.98 vs. 31.43±1.72 cm; p=0.001). This proves that the running and jumping game model effectively improves motor skills impairments in children with intellectual disabilities.

Objectives. This study aimed to analyze the effect of a four-week moderate-intensity exercise regimen on increasing growth hormone (GH) levels in individuals with obesity. Materials and methods. A total of 25 female individuals aged 20-25 years, with a body mass index (BMI) of 27.50-37.00 kg/m², were involved in the study and randomly divided into two groups, namely the control group (CON; n = 12) and the moderate-intensity exercise group (MIE; n = 13). The moderate-intensity exercise regimen (treadmill exercise for 30 minutes at 60-70% of HRmax, and resistance exercise for 30 minutes at 60-70% of 1RM) was conducted 3 times per week for a period of 4 weeks. Blood samples from participants were collected pre- and post-exercise sessions, and GH levels were analyzed using the Enzyme-Linked Immunosorbent Assay method. Data analysis techniques used the paired sample t-test with a significance level of 5 %. Results. The paired sample t-test results of GH levels between the pre-exercise and post-exercise sessions in the CON group showed a change from (1291.79 ± 383.76 to 1151.53 ± 484.80 pg/mL; p = 0.694), while the MIE group demonstrated the following dynamics of change — from (1161.79 ± 133.72 to 2103.83 ± 357.09 pg/mL; p = 0.006). Conclusions. The main findings of this study revealed that after implementing a four-week moderate-intensity exercise intervention, a significant increase in GH levels was observed in obese females.

This study aimed to determine the effect of cardio and tabata training on reducing body fat and increasing aerobic capacity. This research is an experimental research with a pre and post-control group design. The research sample was split into three groups, each with 9 participants: control group (K1), cardio group (K2), and Tabata group (K3), group division was carried out randomly on research subjects. K1 without any exercise, whereas K2 (cardio) is running and skipping at an intensity of 55% and 70% of one's maximum heart rate. K3 (Tabata) performs burpees and jogging with a 90% – 95% HR maximum intensity. A skinfold calliper was used to quantify body fat, and a 12-minute Cooper test was used to gauge aerobic capacity. The Manova test was employed for data analysis, and a significance threshold 0.05 was used. The result of this study is that K3 had significantly less body fat than K1 and K2, and K2 had significantly less body fat than K1 (p 0.05). Comparing K3 and K2 to K1, aerobic capacity was substantially improved (p 0.05). In conclusion, six weeks of cardio and Tabata training impacted lowering body fat and raising maximum aerobic capacity.
