Adaptations to 4-s Sprint Interval Training at Different Intensities
NCT06906393 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of this study is to investigate the chronic effects (i.e., 8 weeks, 3 times per week) of training at 50% and 75% of maximal power with 4-s sprint interval training on physiological adaptations. We previously examined the effect of training with an all-out intensity (i.e., 100% of maximal power) and reported increases in cardiorespiratory fitness. Now, we propose to examine the effects of a lower exercise intensity domains on cardiovascular fitness and its ability to stimulate the cardiorespiratory system. We hypothesize that training at 50% and 75% of maximal power will improve cardiorespiratory fitness similar to our previous findings while reducing the rate of perceived exertion during the exercise session. It is anticipated that the group engaged in training at 75% of maximal power will experience greater improvements in comparison to the group training at 50%.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06906393
The ClinicalTrials.gov registry entry for NCT06906393 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 24 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Texas at Austin, which has 225 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Cardiovascular Fitness appearing as the primary indexed condition, and to 1 intervention — of which Preventive treatment is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06906393 reports 1 study location spanning 1 distinct geographic area — top geographies include Texas. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
