Summary
This summary is machine-generated.Aquatic exercise significantly boosts irisin and fibroblast growth factor 21 (FGF-21) in elderly women, enhancing fat metabolism. This exercise type also positively impacts triiodothyronine (T3) and free fatty acid (FFA) levels.
Area Of Science
- Exercise Physiology
- Endocrinology
- Gerontology
Background
- Investigated the effects of different exercise modalities on key metabolic and hormonal markers in elderly women.
- Focused on irisin, fibroblast growth factor 21 (FGF-21), triiodothyronine (T3), and free fatty acid (FFA) levels.
Purpose Of The Study
- To compare the impact of aquatic exercise versus land exercise on specific biomarkers in older women.
- To determine if exercise type influences hormonal changes related to fat metabolism.
Main Methods
- 30 women (65-70 years) were divided into aquatic exercise, land exercise, and control groups.
- Participants engaged in 16 weeks of supervised exercise (3 sessions/week, 60 min/session) with progressive intensity increases.
- Biomarker levels (irisin, FGF-21, T3, FFA) were measured before and after the intervention.
Main Results
- Aquatic exercise led to significant increases in irisin and FGF-21 levels compared to land exercise and control.
- Both exercise groups showed elevated T3 levels post-intervention.
- The aquatic group exhibited significantly higher FFA levels, indicating enhanced fat metabolism.
Conclusions
- Aquatic exercise is a potent stimulus for increasing irisin and FGF-21 in elderly women.
- Exercise-induced hormonal changes, particularly in the aquatic environment, can promote fat metabolism and brown fat activation.
- Environmental factors in aquatic exercise may enhance its metabolic benefits compared to land-based exercise.

Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
