Study summary

This project is prompted by the urgent public health need to identify novel strategies to prevent and treat tobacco-related cardiovascular disease (CVD) and by compelling pilot data that suggests cessation of smoking results in rapid amelioration of endothelial function. The higher prevalence of CVD and metabolic syndrome in smokers have become major health care concerns. Therefore, finding optimal intervention strategies to combat these growing epidemics is imperative. We are investigating the efficacy of resistance training to ameliorate endothelial dysfunction, oxidative stress, inflammation, and insulin resistance in four groups: presence or absence of resistance training with or without cessation treatment + nicotine replacement.

The investigators hypothesize that resistance training will improve cardiovascular function in smokers; however, the responses will be better in those who also stop smoking. In addition, resistance training will decrease smoking, however, the effects of counseling and nicotine replacement alone or counseling and nicotine replacement in conjunction with resistance training will be better than resistance training alone.

Read the detailed description

The investigators are conducting a 12-week randomized-controlled trial of 100 young adult smokers.

At week 0, participants attend three outpatient visits at baseline. Each participant is randomized to one of four groups: Resistance Training(RT)/Nicotine Replacement Therapy (NRT), RT/No NRT, No RT/NRT, and No RT/No NRT. Those receiving RT work with a certified personal trainer 3 times per week for 12 weeks at 60 minutes each session. Those receiving NRT use the nicotine patch daily for 12 weeks and call the California Smoker's Helpline for smoking cessation counseling. Those in the control group do not receive any intervention and maintain their current lifestyle and habits.

At week 13, participants return for three post-intervention assessments.

At week 26, survey data is collected to assess changes in lifestyle habits.

Inclusion criteria

  • Young Adults (18-35 yrs.)
  • Male and female smokers
  • Smokers (smoked at least one cigarette a day for 15 or more days in the last month and has smoked 100 cigarettes in life)
  • 1-3 years experience consistently exercising/training at ≤2 days/wk of RT and ≤1 day/wk of aerobic exercise
  • Capable of providing informed consent
  • UCLA students/staff and Non UCLA student/staff
  • Participant in good health as determined by baseline visit

Exclusion criteria

Exclusion Criteria:

  • Documented CAD
  • Has had cardiac surgery
  • Currently in weight loss or exercise program in the 6 months prior to participation.
  • Use of medications that influence CV function or preclude the ability to train
  • Syndromes or prescribed medications that may influence CVD, body composition, or insulin action (e.g. prednisone, Ritalin, Adderall, GH)
  • Unable to exercise
  • Diagnosed with syndromes or diseases that may influence body composition and CV risk (e.g. Cushing syndrome).
  • Known heart arrhythmia and/or abnormalities found in electrocardiogram (ECG) reading that would prevent someone from performing the exercise intervention. If the subject demonstrates abnormal ECG during their pre-intervention visit (or any follow-up visit) the subject's ECG will be reviewed (for approval) by a cardiologist to continue in the study.
  • Pregnant
  • Use of hormonal contraceptives
  • Currently in a smoking cessation program including use of NRT within the month of participation

What researchers measure

Primary outcomes

  1. Endothelial function as determined by brachial artery Flow-Mediated Dilation (FMD)

    Time frame: 12 weeks

Secondary outcomes

  1. Smoking cessation percentage

    Time frame: 12 weeks

  2. Arterial stiffness (including PWV and AIx)

    Time frame: 12 weeks

  3. Number of cigarettes smoked

    Time frame: 12 weeks

Other outcomes

  1. Endothelial Progenitor Cells (EPC) count

    EPC count is measured using a novel flow cytometry protocol.

    Time frame: 12 Weeks

  3. Plasma biomarkers inflammation/oxidative stress (oxidized low density lipoprotein (OxLDL), CRP)

    Time frame: 12 Weeks

  4. Body Composition

    Lean mass and fat mass are measured by the Dual Energy X-ray Absorptiometry (DEXA) Scan.

    Time frame: 12 Weeks

  5. Muscle Strength

    Muscle strength is evaluated by a one-Repetition Maximum (1RM) protocol and VO2 peak is assessed by a maximal incremental cardiopulmonary exercise test.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 12, 2012, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
