Resistance Training and Sex Hormone Concentrations During the Menstrual Cycle
A study testing Resistance Training in people with Women's Health, run by Southern Illinois University Edwardsville at 1 site in United States.
Trial summary
Although there are numerous studies showing effects of aerobic training on sex hormone concentrations, research analyzing the fluctuation of sex hormones in response to resistance training (RT) is lacking. Read more about this study

About this study
Official title: Acute Effects of Resistance Training on Sex Hormone Concentrations on Different Phases of the Menstrual Cycle
Although there are numerous studies showing effects of aerobic training on sex hormone concentrations, research analyzing the fluctuation of sex hormones in response to resistance training (RT) is lacking. The objective of this project is to analyze estradiol (E2) and progesterone (P4) responses to an acute resistance training session throughout different phases of the menstrual cycle. This proposed research has strong implications for exercise prescription and for women in general, but more importantly will allow exercise physiologists, coaches, personal trainers, or nutritionists optimize exercise programming around women's menstrual cycle.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Resistance TrainingBehavioural
Participants will exercise at the mid-point of each menstrual cycle phase (EFP- day 4, LFP- day 11, ELP- day 18 and LLP- day 25 for a 28 day menstrual cycle). Training will consist of a warm up. Intensity will be set at 70% of 1RM, and the circuit training will include 7 strength exercises: leg press, rows, back squat, weighted crunches, deadlifts, bench press, and weighted squat jumps. The participant will perform 3 sets f 10 repetitions with 30 seconds of rest

Where is the study taking place?
The record lists 1 site in United States. 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. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Maria Fernandez del Valle, PhD (6186505905, marfern@siue.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in estrogen concentrations (time frame: through study completion, an average of 5 weeks). The study lists 2 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 18 Feb 2020; AzTrials last refreshed its copy on 7 Nov 2026.
