Circuit Training for Postmenopausal Women

This study is looking at whether short-term circuit training can improve muscle mass and quality of life in women who have gone through menopause (postmenopausal) and are currently not very active. Researchers want to see if this type of exercise can help with physical and mental well-being. You could be eligible if you are a woman between 50 and 75 years old, have been postmenopausal for at least 12 months, and haven't regularly exercised in the past six months. The study will measure changes in sleep quality and a marker of inflammation called IL-6 after eight weeks to see if the exercise is successful. The current status of this study is unclear, and it plans to enroll 46 participants.

Study design
This is a randomized controlled trial, meaning participants will be randomly assigned to either an exercise group or a group that maintains their current activity level. The study plans to enroll 46 participants.
What's involved
If you join, you would either participate in a circuit training program for 10 weeks, including warm-up, cool-down, and two 12-minute high-intensity exercise sets, or maintain your usual sedentary lifestyle. You will have initial and final data collection appointments, which include various physical tests, questionnaires, and blood tests.
Compensation
Not stated in the trial record.
Follow-up
The primary outcomes, such as sleep quality and IL-6 levels, will be measured at eight weeks after the start of the study.

Eligibility criteria

Inclusion

Females aged between 50 and 75 years.
Self-reported postmenopausal status (i.e., cessation of menstruation for a minimum of 12 months).
Physically capable of participating in an exercise intervention.
No engagement in structured resistance or aerobic training programs in the six months preceding the study.

Exclusion

Classification as moderate and highly active on the International Physical Activity Questionnaire (IPAQ) (600-3000 MET-minutes/week for "moderate" and higher than 3000 MET-minutes/week for "high" score)
Diagnosis of any health condition that constitutes a contraindication to physical exercise (e.g., significant cardiovascular disease, orthopedic or neuromuscular restrictions impacting exercise performance or safety).
Regular use of medication with the potential to affect study outcomes (e.g., corticosteroids, immunosuppressants).

What this trial measures

  • sleep qualitychange between baseline and eight weeks

    The Pittsburgh Sleep Quality Index will be used to measure any trouble sleeping.

  • IL-6 Biomarkerchange between baseline and eight weeks

    Inflammatory biomarker IL-6 will be tested using a blood draw.
