'Make exercise the elixir across an economic divide': A message to COVID-19 decision makers

Area of Science:

• Immunology
• Public Health
• Exercise Science

Background:

• COVID-19 pandemic necessitated population movement restrictions, including limitations on physical activity.
• Exercise offers significant, well-documented health benefits, particularly for immune function.
• South Africa implemented lockdown measures impacting citizens' ability to exercise.

Purpose of the Study:

• To emphasize the immune-boosting benefits of exercise.
• To highlight exercise's importance for individuals vulnerable to SARS-CoV-2.
• To propose strategies for enhancing exercise accessibility in diverse South African communities.

Main Methods:

• Literature review on exercise and immune function.
• Analysis of lockdown impacts on physical activity in South Africa.
• Development of policy recommendations for accessible exercise programs.

Main Results:

• Exercise demonstrably enhances immune system resilience.
• Vulnerable populations particularly benefit from exercise in mitigating COVID-19 risks.
• Current exercise access is inequitable across South Africa's demographic and economic spectrum.

Conclusions:

• Maintaining exercise is crucial for public health during pandemics.
• Targeted interventions are needed to ensure equitable exercise access.
• Promoting exercise can bolster population immunity against viral threats like COVID-19.
