Objective:

To examine the longitudinal association of different physical activity patterns, particularly concentrated activity, with the incidence of cardiovascular disease (CVD) among overweight and obese individuals, addressing a critical gap in existing research.

Key Findings:

• Concentrated physical activity patterns were associated with a similar reduction in CVD risk as regularly distributed activity among overweight and obese individuals.
• Approximately three-quarters of adults do not meet recommended physical activity guidelines, with perceived time constraints being a significant barrier.

Interpretation:

The findings suggest that concentrated physical activity may be an effective strategy for reducing CVD risk in high-risk populations, potentially enhancing adherence to physical activity recommendations by fitting into busy lifestyles.

Limitations:

• The study's reliance on a single week of accelerometer data may not capture long-term physical activity patterns, potentially underestimating the variability in activity levels.
• Exclusions based on data quality may limit the generalizability of findings, particularly among diverse populations.

Conclusion:

Promoting concentrated physical activity could be a viable public health strategy to mitigate CVD risk among overweight and obese adults, addressing barriers to regular physical activity adherence and suggesting targeted interventions.
