Resistance training and total and site-specific cancer risk: a prospective cohort study of 33,787 US men.

ABSTRACT:

Background

Muscle-strengthening activities have been recommended for health benefits. However, it is unclear whether resistance training is associated with cancer risk, independent of total physical activity.

Methods

A prospective cohort study followed 33,787 men from the Health Professionals Follow-up Study (1992-2014). Cumulative average of resistance training (hours/week) was assessed through biennial questionnaires up to 2 years before cancer diagnosis. Cox regression model was used to estimate the hazard ratio (HR) and 95% confidence intervals (CI).

Results

During 521,221 person-years of follow-up, we documented 5,158 cancer cases. Resistance training was not associated with total cancer risk (HR per 1-h/week increase: 1.01; 95% CI 0.97, 1.05). We found an invers
