Summary
Community-based high-intensity functional training (HIFT) is feasible for older adults with mobility disabilities. The pilot study showed positive effects on function, endurance, and work capacity, indicating program acceptability.
Area of Science:
- Gerontology
- Rehabilitation Science
- Exercise Physiology
Background:
- Limited evidence exists for community-based exercise programs for older adults with long-term mobility disabilities.
- Pilot study to assess feasibility and preliminary effectiveness of community-based High-Intensity Functional Training (HIFT).
Purpose of the Study:
- Investigate the feasibility and acceptability of a community-based HIFT program.
- Evaluate the preliminary effectiveness of HIFT on physical function and quality of life in older adults with mobility limitations.
Main Methods:
- Single-group, pre-post feasibility trial conducted in four HIFT facilities.
- 10 participants (mean age 69.8 years) completed 16 weeks of thrice-weekly group-based HIFT.
- Assessed physical function, mobility, balance, strength, work capacity, and quality of life.
Main Results:
- Recruitment (38%) and retention (77%) rates were documented; attendance was 58% (80% with make-up sessions).
- Significant improvements observed in participant-identified functional activities (large effect), fall efficacy (large effect), and endurance (substantial effect).
- Modest gains in standardized physical function, mobility, balance, strength, and quality of life; work capacity increased significantly.
Conclusions:
- Community-based HIFT is a feasible and acceptable intervention for older adults experiencing mobility disabilities.
- The program demonstrated safety and tolerability, with positive impacts on functional outcomes and endurance.

01:29Intellectual Disability
783
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

01:25Learning Disabilities
636
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

01:21Pilot and Numeric Relaying
496
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

00:58Sound Intensity
4.9K
The loudness of a sound source is related to how energetically the source is vibrating, consequently making the molecules of the propagation medium vibrate. To measure the loudness of a source, the physical quantity of interest is the intensity. This is defined as the energy emitted per unit of time per unit of area perpendicular to the sound wave's propagation direction. Since the total energy is greater if the source vibrates for a longer duration and over a larger area, dividing the...

00:53Sound Intensity Level
4.9K
Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and...

6.0K
The energy transport per unit area per unit time, or the Poynting vector, gives the energy flux of an electromagnetic wave at any specific time. For a plane electromagnetic wave with E0 and B0 as the peak electric and magnetic fields and traveling along the x-axis, the time-varying energy flux can be given by the following equation:
