  • Adult

Study population: trained runners (men and women) who run with a FM strike (self-reported and verified in the laboratory).

Who may be able to join

  • trained runners with a running foot striking style of either initial forefoot or midfoot strike.
  • run on average at least 20 miles/week
  • be able to run for at least 20 minutes at one session
  • free of any orthopedic limitation

  • rear-foot strike running style
  • does not run in a cushioned shoe on any occasion
  • runs on average < 20 miles/week
  • unable to run for 20 minutes or greater
  • presence of any open wound or deformity on the feet which would prevent participant from running barefoot

About this study

Official title: Peak Impact Forces and Metabolic Cost During Mid-Forefoot Striking in Shod Versus Barefoot Runners: A Pilot Study

This experimental study will compare impact forces and metabolic cost in runners (N=20; ages 18-45 years, who already use a forefoot strike running gait) in two treadmill running test sessions (shod vs barefoot running)

Read the detailed description

Specific Aim 1: To identify if differences in metabolic cost exist between barefoot versus cushioned shod FM strikers during an acute bout of running exercise. Hypothesis: The metabolic cost will be higher in the cushioned shod runners with forefoot and midfoot strike compared to the barefoot runners.

Specific Aim 2: To identify if differences in peak impact forces exist between barefoot versus cushioned shod runners in forefoot-midfoot (FM) strikers.

Hypothesis: Peak impact forces will be higher in the barefoot runners with a forefoot and midfoot striking running style compared to the cushioned shod runners with a forefoot and midfoot striking running style.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Metabolic Rate During Barefoot and Shod Running

    This study will measure the metabolic rate when a person runs on the treadmill with shoes (shod) and without shoes.

    Each person will run for 20 minutes on the treadmill on two different days, one with and one day without shoes.

    Measured: Study consists of two visits, approximately 2 hours for each visit

Secondary outcomes (1)
  1. Peak Impact Forces During Barefoot and Shod Running

    This study will be measuring the peak impact forces that a runner produces when running on the treadmill with shoes (shod) and without shoes.

    Each person will run for 20 minutes on the treadmill on two different days, one with and one day without shoes.

    Measured: Study consists of two visits, approximately 2 hours for each visit

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy, run by University of Florida at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 Apr 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Metabolic Rate During Barefoot and Shod Running (time frame: Study consists of two visits, approximately 2 hours for each visit). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Apr 2014.
