Regular physical activity significantly lowers high-sensitivity C-reactive protein (CRP) levels, a key marker of inflammation. This effect is comparable or superior to pharmacological interventions for cardiovascular disease risk reduction.

Area of Science:

  • Biomedical science
  • Cardiology
  • Exercise physiology

Background:

  • Cardiovascular disease (CVD) is a major global health concern.
  • Inflammation plays a critical role in atherosclerosis development and progression.
  • Novel inflammatory markers like high-sensitivity C-reactive protein (CRP) aid risk assessment.

Purpose of the Study:

  • To review evidence demonstrating physical activity's role in reducing CRP levels.
  • To examine the dose-response relationship between physical activity and CRP reduction.
  • To explore factors influencing CRP response to exercise.

Main Methods:

  • Systematic review of cross-sectional and longitudinal studies.
  • Analysis of data linking physical activity, cardiorespiratory fitness, and CRP levels.

  • Examination of studies investigating exercise interventions and CRP changes.

    • Main Results:

    • Higher physical activity and cardiorespiratory fitness correlate with 6-35% lower CRP levels.
    • Longitudinal studies show CRP reductions of 16-41% with training.
    • Exercise-induced CRP reduction may be independent of body composition or weight loss.

    Conclusions:

    • Physical activity effectively lowers CRP levels in a dose-dependent manner.
    • The anti-inflammatory effect of exercise on CRP is a significant adjunct to CVD risk reduction.
    • Factors like diet, smoking, and body composition may modulate the exercise-CRP relationship.
