Abstract

This study intends to determine the gross motor skills of deaf students at extraordinary schools using a survey method from a learning perspective. This is a quantitative descriptive study. This research was conducted at one of the schools in the city of Makassar, namely Public SLB 1 Makassar. The sample used in this study was 15 students using the Purposive Sample method. The data collection technique involved conducting a motor ability test, which included activities such as walking on a straight line for 5 meters, zigzag running for 15 meters, standing on one foot for 10 seconds, and jumping from a 15 cm block. The quantitative descriptive data analysis technique was employed. The results indicated that the gross motor skills of deaf children fell into the good category for 11 (73%), the sufficient category for 4 (27%), and the less category for 0 (0%). So it can be concluded that the gross motor skills of deaf students at Public SLB 1 Makassar are in the excellent category from a learning perspective, especially the PJOK subject.

Abstract

Abstract This study aims to examine the impact of isometric training on increasing muscle capacity and energy efficiency in soccer athletes. A total of 30 soccer athletes from the Faculty of Sport and Health Sciences, Universitas Negeri Makassar (UNM) were divided into two groups, namely the experimental group that underwent isometric training for 8 weeks and the control group that did not undergo the treatment. The isometric training program was carried out 3 times a week, with a duration of each training session of 30 minutes. The variables measured in this study included muscle strength, energy efficiency, oxygen use, and heart rate. Measurements were taken before and after the intervention in both groups to evaluate the differences that occurred. The results showed that the experimental group experienced a significant increase in muscle strength (from 75.4 ± 6.5 kg to 82.7 ± 5.4 kg) and energy efficiency (from 65.2 ± 4.3% to 70.8 ± 3.7%). In addition, there was a significant decrease in oxygen utilization (from 42.3 ± 3.1 ml/kg/min to 39.8 ± 2.8 ml/kg/min) and heart rate (from 138.5 ± 10.2 bpm to 132.4 ± 9.1 bpm). In contrast, the control group did not show significant changes in these variables. Based on these findings, it can be concluded that isometric training has a positive effect on increasing muscle strength and energy efficiency, as well as decreasing oxygen utilization and heart rate in soccer athletes.
