This study will be a randomized controlled trial involving 30 participants, with data collected from the Sanai school system in Sargodha. The study will include school-aged children with normal weight between the ages of 10 and 14. Children with any cardiorespiratory conditions, hemophilia, muscular dystrophy, or a history of cardiovascular events will be excluded. The sample of 30 will be divided into two groups of 15 participants each. Group A will participate in tai chi exercises across three levels, while Group B will engage only in basic arts and crafts activities. The interventions will consist of 10 sessions, conducted at a rate of 5 sessions per week over 2 weeks. To assess the respiratory fitness of the children, data will be collected using the 6-minute walk test and the Timed Up and Go test. Data analysis will be performed using SPSS version 26.0.
