The goal of this clinical trial is to examine the effects that functional training may have on the development of fundamental motor skills and to create a systematic functional training program suitable for healthy children aged 6-7 years.

The main question[s] it aims to answer are:

• [To examine the effects of functional training on FMS among children aged 6-7 years.]
• [To compare the effects of functional training on FMS between boys and girls]

This study will include an experimental group and a control group. The experimental group will engage in functional training, while the control group will follow the state-mandated physical education curriculum. Through experiments, we will investigate the effect of functional training on children's fundamental motor skills and assess whether the experimental group's intervention effect is superior to the control group. The samples in this study were normal Chinese children aged 6-7 years. There were 40 people in both the experimental and control groups, including 20 boys and 20 girls

Training intervention information This study will include an experimental group and a control group. The experimental group will engage in functional training, while the control group will follow the state-mandated physical education curriculum. Through experiments, we will investigate the effect of functional training on children's fundamental motor skills and assess whether the experimental group's intervention effect is superior to the control group. The samples in this study were normal Chinese children aged 6-7 years. There were 66 people in both the experimental group and control groups, including 35 boys and 35 girls.

Training Intervention Protocol for experiment group The selection of training items and content and the design of the training plan are based on the training content and principals involved in books such as the physical and motor function training for children, edited by Zhang Xiuli et al. (2018), the physical function training manual for adolescents and children edited by Wang Xiong (2019), and the functional training edited by Santana (2016). Furthermore, based on the literature review, the training frequency for the experiment was two (2) times a week, each lasting 45 minutes, including a 5-minute warm-up phase, a 35-minute main training phase, and a 5-minute relaxation phase, for a total training time of 12 weeks. The content was changed every two (2) weeks, and the intensity of the main phase of training ranged from 60% to 70%.

Training Intervention Protocol for control group The training content of the control group will be selected by the Compulsory Education Physical Education and Health Curriculum Standard in the year 2022. This standard follows the school's physical education teaching plan; the students in the control group will participate in the school's standard physical education curriculum. The specific content will be based on the actual physical education curriculum of the school. The training frequency for the control group was two times (2) a week, each lasting 45 minutes, and for a total training time of 12 weeks.

Inclusion Criteria:

1. Chinese Children in Taiyuan
2. Primary school children are aged 6-7
3. Including both gender boys and girls

Exclusion Criteria:

1. Children cannot normally participate in regular physical education courses.
2. The children have movement disorders.
3. The children have physical or mental diseases.
4. During the training period, the children have to do other sports training.

The procedure for selecting samples will make use of stratified sampling in addition to a random number table.

in order to avoid the Contamination caused by the mutual interference between the experimental group and the control group, blinding was necessary in the study. In this study, a single-blind experiment will be used to blind the participating children. During sample selection and grouping, the participating children will not know the specific grouping situation, and will not be informed of the relevant experimental objectives
