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.

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.

Experimental: Reformer Pilates
reformer pilates- 46-60 age
Other: Reformer Pilates
Reformer Pilates is a low-impact exercise method performed using spring-based equipment that aims to improve muscle strength, flexibility, core stability, and postural control in women aged 18-46 through controlled and precise movements.

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
Time Frame
Flexibility Assessment
Time Frame: 5 weeks
Flexibility was assessed using the Sit-and-Reach Test
5 weeks
Sørensen Test
Time Frame: 5 weeks
This test is a widely used and reliable method for assessing the isometric endurance of the erector spinae muscles
5 weeks
Trunk Flexor Endurance Test
Time Frame: 5 weeks
Participants were positioned in a seated posture with the trunk inclined at 60°, the knees flexed at 90°, and the arms placed either across the chest or behind the head. Participants were instructed to maintain their trunk at this angle for as long as possible, and the endurance time was recorded in seconds using a stopwatch. This test was conducted to assess the isometric endurance of the trunk flexor muscles, particularly the rectus abdominis and iliopsoas muscles
5 weeks
Lateral Bridge (Side Bridge) Test
Time Frame: 5 weeks
Participants were positioned in a side-lying posture, supporting their body on the lower arm and the lateral aspect of the feet, maintaining the trunk in a straight line. The upper arm was placed on the hip, and participants were instructed to hold this position for as long as possible. The endurance time was recorded in seconds using a stopwatch. This test is a commonly used method to assess the isometric endurance of the oblique muscle groups and the quadratus lumborum muscles
5 weeks
Muscle Strength and Body Composition Assessments
Time Frame: 5 weeks
In this study, the Visbody 3D body analysis system was used to evaluate participants' body composition and postural characteristics through millimetric three-dimensional scanning. The system provided segmental muscle mass analysis for the upper extremities, lower extremities, and trunk, enabling a detailed assessment of the relationship between muscle distribution and strength and endurance outcomes. In addition to body composition parameters such as body fat, fat-free mass, BMI, and visceral fat, postural variables including spinal alignment, shoulder and pelvic symmetry, pelvic tilt, and shoulder joint angles (abduction and flexion) were assessed. Overall, Visbody supplied comprehensive, multidimensional data that supported functional test results and enhanced measurement reliability.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 6, 2025

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
