Hypertension in master endurance athletes

Area of Science:

• Exercise Physiology
• Cardiovascular Health
• Preventive Medicine

Background:

• Hypertension is a major global health concern.
• The role of intense, long-term exercise in preventing hypertension requires further investigation.
• Master athletes represent a unique cohort for studying the long-term effects of vigorous physical activity.

Purpose of the Study:

• To investigate whether sustained, high-intensity endurance training can prevent the development of hypertension.
• To compare hypertension prevalence in elite master orienteering runners versus a healthy control group.

Main Methods:

• A cohort study design was employed in Finland.
• 264 male master orienteering runners (top-ranked in 1984) and 388 age-matched healthy male controls (healthy at age 20 in 1985) completed a health questionnaire in 1995.
• Hypertension was assessed via self-reported medication use.

Main Results:

• The prevalence of hypertension medication use was significantly lower in the endurance athlete group (8.7%) compared to the control group (27.8%).
• After adjusting for age and body mass index, the odds ratio for hypertension in athletes was 0.43 (95% CI, 0.25-0.76), indicating a protective effect.
• The findings suggest a substantial reduction in hypertension risk associated with long-term vigorous endurance training.

Conclusions:

• Long-term, vigorous endurance training is associated with a considerably lower prevalence of hypertension.
• While reduced body mass contributes, exercise appears to offer additional protective mechanisms against hypertension independent of weight loss.
• These findings support the recommendation of intense endurance exercise for hypertension prevention.
