Study summary

This study aims to test the effect of three cognitive strategies to affect individuals' subjective experience of cardiovascular exercise. Participants will be randomly assigned to one of three strategies to use while exercising, both during an in-person session and self-directed two week exercise period.

Inclusion criteria

  1. Between the ages of 18 and 40.
  2. Insufficiently physically active for the past 6-months (i.e., does not meet American College of Sports Medicine [ACSM] guideline for cardiorespiratory exercise). The ACSM guidelines state that all healthy adults should engage in a minimum of 150 minutes per week of moderate intensity cardiorespiratory exercise, or 75 minutes per week of vigorous intensity exercise, or an equivalent combination of the two). On the eligibility screen assessment, we will define moderate and vigorous intensity exercise. Then we will ask individuals to report how many minutes of moderate and vigorous intensity exercise they engage in per week. We will use the ACSM's rule of thumb that 1 minute of moderate intensity exercise is equivalent to 2 minutes of vigorous intensity exercise. This will help to ensure that prospective participants who exercise for less than 150 minutes per week are not actually meeting the ACSM guidelines for cardiorespiratory fitness by engaging in vigorous intensity exercise. Thus, if total minutes of moderate intensity exercise and total minutes of vigorous intensity exercise (multiplied by 2) per week is equal to or greater than 150, callers will not be eligible for study inclusion.
  3. Physically capable of safely engaging in moderate-intensity physical activity (PA)
  4. Able and willing to access the Internet daily for two weeks
  5. Willing to accept random assignment.
  6. Have a smartphone or other mobile device (e.g., iPod Touch) that can play media (important if participants are assigned to the distraction condition)
  7. Willing to engage in an exercise intervention specifically involving walking, jogging, running, or hiking (not other types of exercise)

Exclusion criteria

Exclusion Criteria:

  1. Are diabetic or receiving treatment for a metabolic disorder
  2. Are currently pregnant
  3. Are currently on antipsychotic medications
  4. Have a history of cardiac or respiratory disease
  5. Are receiving treatment for a heart condition or high blood pressure
  6. Experience chest pains during and/or not during physical activity
  7. Have a muscle, bone, or joint problem or injury that limit movement, make exercise painful, or could be made worse by exercising
  8. Have a close family history of an adverse cardiac event before the age of 50.

Study arms

  • Experimental
    Mindfulness

    Participants will use the strategy of mindfulness, i.e., present moment awareness with nonjudgment and acceptance, while exercising.

    Behavioral: Mindfulness

  • Experimental
    Distraction

    Participants will use the strategy of distraction, i.e., directing their attention to something other than exercise (specifically a podcast) while exercising.

    Behavioral: Distraction

  • Active comparator
    Self-Monitoring

    Participants will monitor their internal experience while exercising, without distraction and without being taught mindfulness skills of nonjudgment and acceptance.

    Behavioral: Self-monitoring

Interventions

  • BehavioralMindfulness

    Participants will use mindfulness techniques while exercising

  • BehavioralDistraction

    Participants will distract themselves while exercising

  • BehavioralSelf-monitoring

    Participants will use associative attentional focus while exercising

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Dec 2017 to primary completion in Aug 2018, 8 months.

Of 5,147 non-industry interventional studies with no phase under Motor Activity, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 36. This study's 8 months is below that.

Counting every sponsor, half of 5,207 studies reached it within 17 months; a quarter within 7 and three quarters within 36.

How these figures are worked out, and which studies are left out of them.

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, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
