Abstract

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.

Abstract

ABSTRACT The purpose of this research is to describe the physical condition differences between female athletes indoor hockey of East Java Team and National Team. Data sampling is taken from 12 female athletes indoor hockey of PON 2016 with age range 17-28 years old and 12 athletes of indoor hockey of Indonesia's National Team at SEA Games 2017 with age range 19-28 years old for comparison. Physical condition that measured is VO2max to represent endurance, abdominal muscle strength, speed and flexibility. Obtained data is then analyzed using SPSS. VO2max of East Java Team is (39.54±4.18) ml/kg/minute and for National Team is (43.43±7.59) ml/kg/minute (ρ=0.14). For abdominal muscle strength, East Java Team has (41.50±7.01) kg and National Team has (51.83±3.32) kg (ρ=0.00). For Speed, East Java Team has (3.59±0.30) second and National Team has (3.94±0.38) second (ρ=0.51). For Flexibility, East Java Team has (23.75±5.10) cm and National Team has (29.50±4.91) cm (ρ=0.01). From these data we can conclude that East Java Team physical condition is under National Team and it has significant differences at flexibility and abdominal muscle strength. Furthermore, optimal interventions are needed to improve both of those physical conditions. Keywords: hockey, endurance, flexibility, strength, speed

Abstract

The sprint start is a critical determaint of performance because it strongly influences an athlete’s ability to generate rapid acceleration during the initial phase of a sprint. This study aimed to evaluate the sprint start technique of adolescent athletes from the Golden Athletics Club, Surabaya, through video-based biomechanical analysis. A descriptive quantitative design with an observational approach was employed. Ten active 100-meter sprinters aged 15–16 years, consisting of eight males and two females, were recruited using total sampling. Kinematic analysis was conducted using the Kinovea software to assess four variables: anterior knee angle, posterior knee angle, trunk inclination, and first-step length. Intra-rater reliability demonstrated percentage errors below 5% for all variables, indicating excellent measurement consistency. The findings showed that most athletes demonstrated anterior knee angles within the fair-to-good range, whereas posterior knee angles generally remained below the recommended biomechanical range. Excessive trunk inclination was observed in most participants, suggesting suboptimal body positioning during block clearance. First-step length ranged from 81.0 to 102.5 cm, with most athletes demonstrating acceptable performance. Overall technique scores ranged from 43.75% to 75.00%; one athlete was classified as good, four as fair, and five as poor. These findings indicate that sprint start technique among the participating athletes requires further improvement, particularly in lower-limb positioning and trunk alignment, to enhance horizontal force production during the acceleration phase. Kinovea-based video analysis provides a practical and accessible method for evaluating sprint start mechanics in field-based training settings. Nevertheless, because this study involved a small sample from a single athletics club and did not include sprint performance outcomes, the findings should be interpreted within the context of the study and should not be generalized to broader athlete populations.
