New exercise study targets muscle weakness in obese women
NCT ID NCT07407621
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether an 8-week program of eccentric (lengthening) resistance training can improve muscle strength, nerve function, and health markers like blood sugar and cholesterol in obese, inactive women. 24 women aged 25-45 with a BMI over 23 will be assigned to either eccentric or concentric (shortening) training. The goal is to see which type of exercise leads to better muscle and metabolic adaptations.
