Figure 1.

Hazard ratios of metabolic syndrome by the combination of weekly frequency (1–2 vs ≥3 times/week) and minutes of resistance exercise (0, 1–59, 60–119, 120–179 and ≥180 min/week). The dots indicate hazard ratios and the lines present 95% confidence intervals. The model was adjusted for age (years), gender, examination year (year), body mass index (kg/m²), current smoking (yes/no), heavy alcohol drinking (yes/no), abnormal electrocardiography (yes/no), parental history of cardiovascular, hypertension, diabetes (yes/no for each), and aerobic exercise (inactive, insufficient, medium and high). Analysis in the category of ≥180 minutes in 1–2 sessions resistance exercise per week was not applicable (NA).
