How aging affects muscle mitochondria
This study looks at how aging affects muscle cells, especially mitochondria (the energy powerhouses in your cells). They are comparing people who are very inactive with those who are endurance athletes, in both young and middle-aged groups, to understand how exercise might slow age-related changes.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18-30 years old (young group) or 50-65 years old (older group).
- You are either very sedentary (no formal exercise) or highly trained (endurance sports at least 3 times per week).
- You have no chronic health conditions that make exercise unsafe.
- You are not taking medications that interfere with exercise (like corticosteroids, statins, or certain diabetes drugs).
- You are not a current smoker or recent regular smoker (within 12 months).
- You have no metal implants or claustrophobia that would prevent an MRI.

This study looks at how different older adults respond to exercise. It will help researchers understand why some people benefit more than others. You will be asked to do supervised exercise sessions and tests over about 6 months.
This study compares the health of older adults (over 55) who have been very active their entire adult lives with those who have been mostly inactive. The goal is to see how exercise affects muscle, nerves, and immune-metabolic health over time.
This study looks at why older adults have trouble building and keeping muscle. It tests how the body uses protein and exercise to help understand muscle loss with aging.
This trial tests how exercise affects muscle health in people aged 60 or older with multiple sclerosis. It may help you understand if a structured exercise program can improve your strength and mobility.
This study tests if whole-body electrical muscle stimulation exercise helps improve nerve signals to muscles in older adults. It compares older participants (65+) with younger ones (18-39) to see how this type of exercise affects muscle activation.
This study looks at how age affects the way your body uses insulin (a hormone that helps move sugar into cells), and how lifestyle or exercise may change that. It may help you understand insulin resistance and whether changes in activity could improve blood sugar control.
