Functional Exercise Improves Mobility Performance in Older Adults With Type 2 Diabetes: A Randomized Controlled Trial
Journal of Physical Activity & Health
|May 25, 2019
Summary
Functional circuit training improved mobility in older adults with diabetes. This exercise program enhanced gait speed and walking distance, promoting independence and activity.
Area of Science:
- Gerontology and Exercise Science
- Diabetes Management and Complications
- Rehabilitation and Physical Therapy
Background:
- Diabetes-related disability affects two-thirds of older adults, leading to reduced independence and increased healthcare use.
- Sedentary lifestyles exacerbate mobility issues in older adults with diabetes.
- Targeting mobility function is crucial for maintaining independence in this population.
Purpose of the Study:
- To evaluate the impact of a center-based functional circuit training (FCT) program followed by a home-based intervention on mobility in sedentary older adults with diabetes.
- To compare the efficacy of FCT with physical activity optimization against control groups receiving health education.
Main Methods:
- A randomized controlled trial involving 111 older adults (mean age 70.5 years, BMI 32.7 kg/m²).
- Participants were assigned to: FCT plus physical activity optimization (FCT-PA), FCT plus health education (FCT-HE), or flexibility and toning plus health education (FT-HE).
- Intervention duration was 20 weeks, with mobility outcomes assessed at 10 and 20 weeks.
Main Results:
- The FCT-PA group showed clinically meaningful improvements in comfortable gait speed (0.1 m/s) and 6-minute walk distance (80 ft) compared to FT-HE.
- At 20 weeks, significant improvements in gait speed and 6-minute walk were observed for FCT-PA versus FT-HE and FCT-HE versus FT-HE.
- These mobility enhancements suggest functional exercise training's effectiveness in this demographic.
Conclusions:
- Functional circuit training is effective in improving mobility among overweight/obese older adults with diabetes and comorbidities.
- The findings support the use of targeted exercise interventions to combat diabetes-related disability.
- Further research should explore long-term sustainability and adaptations for individuals with severe mobility impairments.

01:22Diabetes Mellitus: Type 2 and Gestational
4.4K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

01:27Exercise and Muscle Performance
2.3K
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...

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

1.6K
The role of the detectors in High-Performance Liquid Chromatography (HPLC) is to analyze the solutes as they exit from the chromatographic column. The detector recognizes the solute's property and generates corresponding electrical signals, which are converted into a readable graph of the detector's response versus elution time called a chromatogram at the computer. There are several types of HPLC detectors, each with its own advantages and limitations, depending on the analyte...

2.3K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
