About this study

Official title: Effects of Pilates Training and Protein Supplementation on Body Composition, Performance, and Biochemical Indices

Pilates training, a type of mind and body exercise that focuses on muscle strength and flexibility, has become increasingly popular in recent years. Research has shown that Pilates could be an effective exercise form to improve body composition, particularly in obese individuals, while beneficial effects on flexibility, muscular strength, and muscular endurance have also been observed in young and older adults. It is well documented that protein supplementation can augment the effects of resistance training on body composition and performance. While there is an abundance of studies investigating the effect of protein supplements on adaptations to resistance exercise, there is a knowledge gap regarding their effectiveness in Pilates training.

The aim of this research is to investigate the effects of protein supplementation, compared to placebo (maltodextrin) on body composition, performance, and biochemical indices in healthy young and middle-aged, eumenorrheic (regular menstrual cycle) women who perform Pilates. Participants will be randomly assigned to receive either 0.6 g of whey protein or maltodextrin per kg body weight per day for 10 weeks. Participants will be asked to avoid modifying their dietary habits for the duration of the study to limit the effect of diet on the measured parameters. To check for this, participants will record their diet for 3 days (2 weekdays and one weekend day) on the first, middle, and last weeks of the intervention. Dietary records will then be analyzed. Pilates classes will be performed at least two times per week, while specialized Pilates equipment (Reformer or Cadillac) will be used according to the Pilates principles. The duration of each workout will be set at around 50 min.

Participants will undergo measurements of body composition, core muscle endurance, and joint flexibility at the beginning and end of the study. In addition, hematologic parameters, clinical chemistry parameters, hormones, and plasma amino acids will be measured. All these outcome measures will be compared between the whey protein and maltodextrin groups to determine the effectiveness of protein supplementation in Pilates training.

Questions about this trial

What is this clinical trial studying?

A study testing Whey protein and Maltodextrin in people with Exercise Training and Dietary Supplements, run by Aristotle University Of Thessaloniki at 1 site in Greece.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Greece. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Lean mass and fat mass pre-supplementation (time frame: Within one week before the beginning of supplementation.). The study lists 22 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Mar 2024.
