Trial summary
The objective was to determine the effect of six running sessions of high intensity interval training (HIIT) at 1% and 10% incline on VO2max, peak of velocity (VPeak), and time limit of 1% (TLim1%) and 10% (TLim10%) of inclination, as well as the influence of the specificity of training on performance in the different… Read more about this study

About this study
Official title: Effect of Six Running Sessions of High Intensity Interval Training in Different Slopes on Aerobic Performance: a Randomized Controlled Trial
The objective was to determine the effect of six running sessions of high intensity interval training (HIIT) at 1% and 10% incline on VO2max, peak of velocity (VPeak), and time limit of 1% (TLim1%) and 10% (TLim10%) of inclination, as well as the influence of the specificity of training on performance in the different inclines.
Read the detailed description
Our study is assuming greater activation / muscle overload coming from the uphill running. Accordingly, we believe that in a parallel-group design (1% or 10% gradient) established in controlled and randomized way we could answer the hypothesis that muscle overload provide superior gains to VO2max and aerobic performance. Moreover, considering the first hyphotesis, such developments on the running at 10% slope also promote significant gains in climb performance and also in the plan. Unlike the speculate that the gains from the 1% training does not help performance a 10% incline.

Questions about this trial
What is this clinical trial studying?
A study testing Interval Training at 1% Incline and Interval Training at 10% Incline in people with Healthy, run by Universidade Federal do Rio de Janeiro.
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 2 inclusion and 3 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 30 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Maximal oxygen uptake (VO2Max) (time frame: 0 week - 3 week (2 sessions for week)). 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 30 Jul 2015; AzTrials last refreshed its copy on 29 Oct 2026.
