Brief Summary

With the advancement of technology and changes in lifestyle, the physical activity levels of modern children have gradually decreased. This affects their physical health, psychological development, and social skills, and may increase the risk of nearsightedness. Therefore, it is essential to implement muscle training and outdoor activities in schools, travel agencies, and kindergartens. This project aims to promote the comprehensive development of children through systematic muscle training and enhanced outdoor activities, integrating college students from early childhood education programs, travel agencies, and kindergartens to establish habits that prevent nearsightedness.

In the kindergarten setting, 60 children in the senior class will serve as the control group, while another 60 will be in the intervention group. The intervention group will participate in 10 weeks of muscle training and outdoor activities, including core exercises 3 times a week for 60 minutes each session from 4pm to 6pm. Additionally, there will be subsidized a total of 2 outdoor activities on weekends. This approach will not only improve the children's coordination and flexibility but also enhance their physical fitness. Regarding travel agencies, tailored outdoor activities specifically designed for young children can be created, such as ecological explorations and wilderness survival training, allowing children to enjoy the fun of movement and learning in a safe environment. Travel agencies should collaborate with educational institutions to provide professional guidance and safety assurances, giving parents peace of mind. For kindergartens, a comprehensive outdoor activity plan should be established, regularly organizing sports days and group competitions to encourage children to participate in team sports like soccer and relay races. This not only helps improve the children's muscle strength but also fosters their spirit of cooperation and social skills. Through these methods, we aim to effectively increase children's activity levels, promote their overall development, and reduce the risk of nearsightedness.

Detailed Description

Body composition includes Metabolic age, body fat percentage, BMI, total body water (%), BMR (Basal Metabolic Rate), Visceral Fat, physique ratings, muscle quality, muscle mass. Body composition was examined by the TANITA RD-545 (Tanita Corporation, Tokyo-Japonya). Tanita Home Page. Available online: https://tanita.eu/understanding-your-measurements (accessed on 13 August 2022). The FSM is a standardized, norm-referenced test of functional strength for children aged 4-10 years (Smits-Engelsman, 2012).

The FSM consists of eight items that measure anaerobic muscular endurance (30-second sit-to-stand times, lateral up-and-down, box lift, and stair test) and muscular strength (overhand throw, underhand throw, chest throw, and standing long jump). For anaerobic muscular endurance items, the number of repetitions in a 30-second period is counted; for muscular strength items, the distance covered is measured in centimeters.

The Visual_Fatigue_Questionnaire is based on the subjective feelings of the subjects and contains 6 questions using a 5-point Likert scale. The subjects are required to circle the score that best describes their current state (1 represents not at all, 2 represents almost not, 3 represents average, 4 represents somewhat severe, and 5 represents very severe) among the following 6 questions.
