INTERVENTIONAL
Conditions
Summary
This study has two phases: Phase 1 is to examine blood pressure, microvascular function, and sympathetic nerve activity in mid-life adult binge drinkers vs. alcohol abstainers/moderate drinkers. Phase 2 is to examine the effect of 8-week aerobic exercise training on blood pressure, microvascular function, and sympathetic nerve activity in mid-life adult binge drinkers
Eligibility

- other known traditional cardiovascular disease risks: obesity (BMI≥35 kg/m2), or hyperlipidemia (total cholesterol\>230 mg/dl and/or LDL cholesterol\>160 mg/dl)
- active infection (in the past 2 months)
- a history of seizures, cancer, or inflammatory disease (i.e., gout or rheumatoid)
- unstable body weight (\>5% change during the past 6 months)
- regular aerobic exercise training (i.e., they engage in 30 min of structured aerobic exercise at least 3 times per week)
- current use of hormone replacement therapy (i.e., estrogen, progesterone, and testosterone)

Interventions
Subjects will be asked to perform exercise training (high-intensity interval training) under supervision, 3 times per week for 8 weeks. Each training session will last 40 minutes and will consist of 10-minute warm up at 70% of maximal heart rate (HRmax), four 4-minute intervals at 90% of HRmax with 3-min active recovery at 70% of HRmax and 5-minute cool down at 70% of HRmax.
Subjects will be asked to abstain from alcohol for 8 weeks. Education materials and bi-weekly consultations will be provided.
