Walking Training Improves Thyroid and Cardiometabolic Markers in Postmenopausal Obesity

Moderate Intensity Intermittent Walking Training (MIWT) Improves Thyroid Function and Cardiometabolic Risk Factors in Obese Postmenopausal Women

The goal of this clinical trial is to investigate the impact of a 10-week MIWT program on thyroid hormone levels and key cardiometabolic markers in obese postmenopausal women. The main question it aims to answer is:

Does MIWT enhance thyroid function and reduce cardiometabolic risk factors in this population? Researchers will compare MIWT (designed to MIWT group) to non-training intervention (designed to control group) to see if the training program works to improve thyroid function and cardiometabolic risk factors.

Participants in MIWT group will: perform a 10-week MIWT program, four sessions per week (5 repetitions of 6-min-walking-test (6MWT) at 60-80% of 6MWTdistance measured at baseline, interspersed by 6-min of active recovery between repetitions).

Participants in control group will : not perform any physical training and maintain their usual daily activities.

This study aimed to investigate the impact of a 10-week MIWT program on thyroid hormone levels and key cardiometabolic markers in obese postmenopausal women. Thirty-six obese postmenopausal women (BMI≥30 kg.m-2, aged 50-60 yrs.) were randomized to either a moderate-intensity intermittent walking training (MIWT) group (n=18) or control group (CG, n=18). Participants performed a 10-week MIWT program, four sessions per week (5 repetitions of 6-min-walking-test (6MWT) at 60-80% of 6MWTdistance measured at baseline, interspersed by 6-min of active recovery between repetitions). Body composition, thyroid hormones (thyroid stimulating hormone (TSH) and thyroxine free (FT4)), lipid profile (triglycerides (TRG), total cholesterol(TC), high-density lipoprotein cholesterol(HDLC) and low-density lipoprotein cholesterol(LDLC)), blood pressure (systolic and diastolic blood pressure) and aerobic fitness (6MWT) were determined before and after the MIWT.

Inclusion Criteria:

• Body mass index≥ 30 kg.m-2.
• Age between 50 and 60.
• Amenorrhea for >12 months.
• Stable eating habits.

Exclusion Criteria:

• Chronic diseases.
• Medical contraindications to physical activity.
• Hormone replacement therapy.
