Abstract

In this study, researchers will find out howeffect of smartphones on gross motor development of children aged 4-6 years in RT 36/ RW 12 Liliba, Oebobo district, Kupang City. The purpose of this study was to determine the effect of smartphones on gross motor development of children aged 4-6 years. The method used in this study is a qualitative descriptive phenomenological approach with data collection techniques in the form of a questionnaire. The subjects of this study were the parents of children aged 4-6 years, totaling 31 respondents. The results of this study are where children in this case do gross motor movements or physical activities that they should do, but the consequences and addiction to playing smartphones are difficultfor children to talk to when they are busy playing their smartphones and difficulty to socialize with friends due to addiction to playing smartphones. The conclusion is that there is an effect of playing smartphones on children aged 4-6 years on gross motor development such as children cannot play outside the house, children become difficult to socialize with their friends, children like to be alone with their smartphones, in the absence of two-way communication.

Abstract

This study aims to examine the musculoskeletal adaptations of indigenous athletes from East Nusa Tenggara (NTT) from a biomechanical perspective. NTT athletes exhibit unique biomechanical characteristics influenced by environmental factors and habitual physical activity from an early age. This study employs a quantitative approach using experimental biomechanics analysis. The research subjects consist of local NTT athletes compared to national athletes in various biomechanical parameters, including bone mineral density (BMD) and ground reaction force (GRF). The results indicate that NTT athletes have higher BMD, particularly in the tibia and femur, demonstrating structural adaptations to repetitive mechanical loading. Additionally, the vertical GRF of NTT athletes is lower during the landing phase, suggesting a more efficient biomechanical strategy for impact absorption. These adaptations contribute to enhanced performance and physical endurance. This study provides new insights into sports biomechanics and can be utilized to design more tailored training programs for athletes in similar regions.
