Isolation Associations of Exercise Intensity on Inflammation: Does Engaging in Moderate or Vigorous Intensity Exercise in Isolation have an Influence on Inflammation? -

Objective: The purpose of this study was to examine whether engaging in certain physical activity intensity levels in isolation (e.g., only vigorous exercise) are associated with C-reactive protein (CRP). Methods: Data were extracted from the 1999-2006 NHANES (7,564 adults; 18-50 yrs). CRP was assessed from a blood sample and participants reported whether or not they engaged in moderate-intensity physical activity (MPA), vigorous-intensity physical activity (VPA), or moderate-to-vigorous physical activity (MVPA). Results: After adjusting for age, gender, race-ethnicity and body mass index, when compared to those who engaged in MVPA, those who engaged in only MPA (βadjusted=0.08; 95% CI: 0.04-0.12; p
