Summary
Fasting during multicomponent exercise training did not offer additional benefits for physically active post-menopausal women compared to exercising in a fed state. Health parameters remained largely unchanged regardless of feeding condition.
Area of Science:
- Exercise physiology
- Nutritional science
- Gerontology
Background:
- Cardiovascular disease (CVD) risk is influenced by modifiable factors like diet and exercise, especially in aging populations.
- Multicomponent training (MCT) is a common exercise modality for improving health in older adults.
- The role of fasting in conjunction with exercise, particularly in post-menopausal women, requires further investigation within the context of aging.
Purpose of the Study:
- To investigate the effects of fasting during a 12-week multicomponent training program on physically active post-menopausal women.
- To compare the outcomes of fasted versus fed exercise training on health parameters in an aging population.
Main Methods:
- 25 physically active post-menopausal women (mean age 60.6 years) were randomized into fed (n=12) or fasted (n=13) groups.
- Both groups underwent 12 weeks of multicomponent training.
- Assessments included anthropometry, body composition, blood pressure, blood markers, and physical fitness.
Main Results:
- A significant reduction in waist circumference was observed in both the fed and fasted groups.
- No other significant differences were found between the fed and fasted groups for anthropometric measurements, body composition, blood pressure, blood markers, or physical fitness.
Conclusions:
- Fasted exercise training did not provide superior benefits over fed exercise training for improving health parameters in physically active post-menopausal women after 12 weeks of multicomponent training.
- These findings suggest that fasting during exercise does not significantly impact health markers in this demographic, aligning with previous research on chronic fasting effects.
- The study highlights that multicomponent training itself may be the primary driver of observed health improvements, irrespective of feeding status.

01:24Metabolic States of the Body: Fasting and Starvation
2.2K
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

3.6K
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

01:18Metabolic States of the Body: The Postabsorptive State
941
The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...
