Meta-Analysis Results on Green Exercise and Mental Health from 51 Studies

51 studies from PubMed, Web of Science, and other databases were synthesized to quantify the mental health benefits of green exercise. The meta-analysis, authored by Xinyi Liu and published in 2026, reports standardized mean differences for well-being, positive affect, and negative affect compared to indoor, built-up, and non-exercise groups. The full results are available in a 1.1 MB PDF file.

Use Cases

• Benchmarking the effect size of green exercise on well-being based on reported standardized mean differences.
• Comparing the impact of green versus indoor exercise on positive and negative affect based on the meta-analysis results.
• Informing the design of future studies on long-term effects and optimal conditions for green exercise.

Strengths

• Results are derived from a systematic review of 51 relevant studies.
• Quantitative effect sizes (Standardized Mean Differences) are provided for three mental health outcomes.
• Comparisons are made against three distinct control groups: non-exercise, indoor exercise, and built-up exercise.

Limitations

• The dataset is a PDF report; the underlying raw study data or column-level documentation is not provided.
• Row count and tabular structure are unknown, limiting suitability for direct computational analysis.
• The 1.1 MB file size indicates a small-scale document rather than a large primary data collection.
