Effects of Regular Activity on Physiology Between Recreational Athletes of Different Body Fatness
NCT05154422 · View on ClinicalTrials.gov ↗
Study Summary
The popularity of marathons and endurance events has increased over the last few decades and, interestingly, the demographics of participants have also changed. From 1980 to 2002 the average race time to complete the marathon lengthened from \~3.5 hours to \~4.5 hours. Likewise, many endurance races include "Clydesdale" and "Athena" divisions for heavier weight male and female runners, respectively. As such, there has been an increase of overweight and obese participants in these races. For example, one study consisting of 250 runners determined, according to BMI, that approximately 15% and 31% of the female and male participants, respectively, were classified as overweight, with 31% and 33% classified as obese. Therefore, many recreational endurance athletes are overweight despite their high level of activity. On one hand, these data are positive as regular exercise reduces cardiovascular disease and all-cause mortality in overweight and obese populations. Yet, it is well documented in sedentary obese individuals that excess adiposity can lead to disturbances in adipocyte lipolysis and altered substrate utilization at rest and during exercise, and can decrease muscle quality. However, it is unknown if overweight individuals that exercise regularly have disrupted fat metabolism, circulating hormones, or muscle quality. No study has directly determined if differences exist in fat metabolism, circulating hormones, and muscle quality between overweight recreational female athletes and their lean counterparts when training status is equivalent. Therefore, the purpose of this investigation is to determine if differences in pre and post-exercise fat metabolism, circulating insulin and growth hormone, and muscle quality exist between active overweight individuals compared to active lean individuals with similar training history and who have regularly trained for and participated in endurance events within the last few years.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05154422
The ClinicalTrials.gov registry entry for NCT05154422 describes a study currently listed as completed. It is categorized as an unspecified phase, 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 15 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Florida State University, which has 291 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Obesity appearing as the primary indexed condition, and to 0 interventions. 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: NCT05154422 reports 1 study location spanning 1 distinct geographic area — top geographies include Florida. 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.
