PURPOSE: Regularly recreational races (RR) can be motivating and help modify social norms regarding participation in regular physical activity (PA). However, the acute physical exertion occurring in RR may trigger cardiac events, especially in high risk individuals. We aim to describe, among RR runners, the prevalence of risk factors for race-associated cardiac events (RFCE) including elevated pre-race blood pressure (PR-BP), positive items in the PA readiness questionnaire (PAR-Q) and non-compliance with PA recommendations (PAR).

METHODS: In September 2010, 3000 runners participated in the "POLAR 10K VIVA"

RR in Bogota, Colombia. Before the run, 445 volunteers completed an on-line survey that included the IPAQ and PAR-Q. Race age categories were youth (<18 y), open (18 to 44 y) and veterans (≥ 45 y). Compliance with the 2008 PAR was calculated for vigorous (VPA ≥ 75 min/week) and moderate-to-vigorous PA (MVPA ≥ 150 or ≥ 300 min/week). A +PAR-Q was coded as 1+ affirmative answers. Pre-race BP was measured by trained personnel among 292 volunteers. Automated sphygmomanometers were placed in participant's left arm after a 5 min standing resting period. PR-BP levels were categorized according to international criteria: stage 1 hypertension (S1HTN): 140-160/90 -100 and stage 2 HTN (S2HTN): 160+/100+. Means and proportions were calculated and significant differences obtained via t-tests and chi-squares.

RESULTS: Overall, 75.1% of survey responders were male, mean age was 37.7 (10.1) y and 16.2% had a +PAR-Q. A total of 18.4% reported non-compliance with the 75+ VPA; 6.4% with the 150+ and 24.7% with the 300+ MVPA PAR. For the pre-race BP sample, 69.5% were male and mean age was 36.9 (13.9) y. Overall, 20.2% had PR-BP at S1HTN levels and 5.8% at S2HTN levels with higher values among males (23.9% vs. 9.1% at S1HTN and 6.5% vs.3.4% at S2HTN levels; all p <0.01). The prevalence of PR-BP at S1HTN and S2HTN levels was highest in the veterans (23.9% and 13.4 %) followed by the open (18.6% and 1.6%) and youth categories (17.9% and 7.1%).

CONCLUSIONS: A troubling large proportion of RR runners convenience sample exhibit RFCE including +PAR-Q, elevated PR-BP levels and non-compliance with PAR. Simple screening protocols can help health professionals identify high risk participants in need of pre-participation medical clearance and follow-up.
