Effects of Different Exercise Types on Irisin, Leptin, and Ghrelin Levels in Sedentary Women (ILEX)

September 1, 2026 updated by: Assoc. Prof. Dr. Özgür EKEN, Inonu University

Investigation of the Effects of Different Types of Exercise on Irisin, Leptin, and Ghrelin Levels in Sedentary Women

This interventional study aims to investigate the acute effects of three different exercise modalities-aerobic exercise, anaerobic exercise, and high-intensity interval training (HIIT)-on irisin, leptin, and ghrelin levels in sedentary women. A total of 20 sedentary women will participate in the study. Hormonal responses will be evaluated in relation to the exercise sessions to determine exercise-induced changes in irisin, leptin, and ghrelin and to compare the responses associated with the three exercise modalities.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This interventional study is designed to investigate and compare the acute effects of aerobic exercise, anaerobic exercise, and high-intensity interval training (HIIT) on irisin, leptin, and ghrelin levels in sedentary women. A total of 20 sedentary women will participate in the study.

Participants will complete three different exercise conditions: aerobic exercise, anaerobic exercise, and HIIT. Irisin, leptin, and ghrelin levels will be evaluated in relation to each exercise condition to determine acute exercise-induced hormonal responses. The study will compare changes in these biomarkers across the three exercise modalities to determine whether the hormonal responses differ according to exercise type.

The study is intended to provide a better understanding of the acute endocrine and metabolic responses to exercise modalities with different physiological demands in sedentary women, with particular emphasis on irisin, leptin, and ghrelin.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria: Female participants Sedentary individuals Voluntary participation in the study Ability and willingness to complete the planned exercise sessions

Exclusion Criteria: Inability to participate in the planned exercise sessions Withdrawal of consent or unwillingness to continue participation

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Multiple Exercise Modalities
Participants in this arm will complete three different exercise conditions in separate sessions: aerobic exercise, anaerobic exercise, and high-intensity interval training (HIIT). Irisin, leptin, and ghrelin levels will be assessed in relation to each exercise condition to evaluate and compare acute hormonal responses across the three exercise modalities.
Behavioral: Aerobic Exercise
Participants will complete an aerobic exercise session as one of the three exercise conditions. Irisin, leptin, and ghrelin levels will be assessed in relation to the exercise session to determine the acute hormonal response to aerobic exercise.
Behavioral: Anaerobic Exercise
Participants will complete an anaerobic exercise session as one of the three exercise conditions. Irisin, leptin, and ghrelin levels will be assessed in relation to the exercise session to determine the acute hormonal response to anaerobic exercise.
Behavioral: High-Intensity Interval Training (HIIT)
Participants will complete a high-intensity interval training (HIIT) session as one of the three exercise conditions. Irisin, leptin, and ghrelin levels will be assessed in relation to the exercise session to determine the acute hormonal response to HIIT.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
