Preschool Fitness Trial Data Comparing Integrated and Conventional Training

Chunmei Zheng's dataset contains results from a 14-week randomized controlled trial with 60 preschool children. The study compares improvements in health-related physical fitness between an integrated functional training group and a conventional physical education group. It includes primary and secondary outcome measures such as grip strength, standing long jump, and 15-m obstacle run times.

Use Cases

• Analyze between-group differences in National Physical Fitness Standard composite scores for the IFT and Conventional PE groups.
• Model the relationship between intervention type and secondary outcomes like grip strength, standing long jump, and sit-and-reach performance.
• Calculate effect sizes (Cohen's d) for improvements across outcomes such as balance beam and two-foot hop results.

Strengths

• Data originates from a dose-matched, assessor-blinded randomized controlled trial, a rigorous study design.
• Includes results for 60 participants with high intervention adherence, exceeding 80% attendance in both groups.
• Reports large, statistically significant effect sizes (Cohen’s d = 1.4–1.9) for all measured fitness outcomes.

Limitations

• The dataset is very small in file size (18.4 KB), indicating limited scope and likely summary-level data rather than raw participant records.
• Sample size is limited to 60 participants from a single-center trial, reducing generalizability.
• The underlying column structure and raw data rows are not specified, limiting direct analytical utility.
