Die klinische Studie NCT04812314 (LG) ist eine interventionsstudie zur Untersuchung von Fettleibigkeit, Metabolisches Syndrom, Stoffwechselkrankheit, Insulinresistenz, Gewichtsverlust, Gewichtszunahme und hat den Status offene rekrutierung. Die Studie startete am 1. März 2021 und soll 46 Teilnehmer aufnehmen. Durchgeführt von Universität Michigan ist der Abschluss für 1. März 2030 geplant. Die Daten von ClinicalTrials.gov wurden zuletzt am 29. Juni 2025 aktualisiert.
Kurzbeschreibung
Participants will be randomized into one of two different experimental groups: 1) Exercise group and 2) No exercise (control group). Subject participation in the study will involve a series of metabolic tests before and after participants undergo a 10% weight loss program (with or without exercise training depending on group randomization). After completing this weight loss portion of the study, participants will then be required to adhere to a high calorie diet program to regain half of the weight the participant lost - followed by the same series of metabolic tests.
Ausführliche Beschreibung
Exercise is among the first line treatments for obesity and obesity-related diseases, yet it is shocking how little is known about how exercise works to improve health. Expanding the knowledge about novel exercise-induced adaptations in fat tissue of obese individuals and furthering the understanding about mechanisms underlying these adaptations could lead to innovative approaches for preventing and treating insulin resistance and obesity-related diseases.

Overall, the researchers believe that exercise training modifies key processes in subcutaneous fat tissue that may contribute to an increase body fat storage capacity (without increasing fat mass). The research team anticipates that exercise will evoke an even more potent adaptive response when fat tissue is dynamically changing in response to alterations in nutritional status (i.e., weight loss and weight regain).

Participants will be randomized into one of two different experimental groups: 1) Exercise group and 2) No exercise (control group). Subject participation in the study will involve a series of metabolic tests before and after participants undergo a 10% weight loss program (with or without exercise training depending on group randomization). After completing this weight loss portion of the study, participants will then be required to adhere to a high calorie diet program to regain half of the weight the participant lost - followed by the same series of metabolic tests. After the participant completes the study, the study team will help the participant to lose more weight. Total involvement in the study for each participant will likely be about 8-10 months.

ExperimentellExercise
This exercise prescription represents a common or "conventional" form of physical activity (e.g., moderate/brisk walking). If assigned to this group, participants will perform 45 minutes of moderate intensity continuous steady-state exercise at 70% maximal heart rate (HRmax) to expend 250 calories 4 days per week.
Übung
Participants will complete a moderate intensity continuous exercise 4 days/week.
ExperimentellNo exercise
Subjects assigned to this group are to remain sedentary (no planned physical exercise) throughout the duration of the study.
Keine Bewegung
Participants will remain sedentary throughout the duration of the study.
