Summary
Active gait speed adjustment involves specific kinematic changes. Muscle activity and gait stability vary during acceleration and deceleration, offering insights for rehabilitation exercises.
Area of Science:
- Biomechanics
- Human Movement Science
- Kinesiology
Background:
- Active adjustment of walking speed is crucial for daily mobility.
- Understanding the underlying kinematic and muscular factors is essential for assessing gait control.
Purpose of the Study:
- To investigate the kinematic adjustments during active gait speed changes.
- To identify the specific factors influencing walking acceleration and deceleration.
Main Methods:
- Evaluated 16 healthy adults during walking acceleration and deceleration.
- Utilized three-axis accelerometers to measure center-of-gravity acceleration (gait stability).
- Employed surface electromyography to quantify muscle activity in lower limb muscles.
Main Results:
- Gait stability (RMS of acceleration) increased during acceleration and decreased during deceleration.
- Muscle activity in gastrocnemius, biceps femoris, and tibialis anterior increased during acceleration.
- During deceleration, biceps femoris activity increased, while other measured muscles showed decreased activity.
Conclusions:
- Specific kinematic mechanisms and muscle activation patterns regulate walking speed adjustments.
- Findings provide a basis for developing targeted exercise therapies to enhance gait speed control in rehabilitation.

The extended Debye-Hückel equation indicates that the activity coefficient of an ion in an aqueous solution at 25°C depends on three partially interdependent properties: the ionic strength of the solution, the charge of the ion, and the ion size.
The activity coefficient value for an ion is close to one when the solution has almost zero ionic strength, i.e., when the solution shows close to ideal behavior. As the ionic strength of the solution increases from 0 to 0.1 mol/L, a...

The importance of understanding acceleration spans our day-to-day experiences, as well as the vast reaches of outer space and the tiny world of subatomic physics. In everyday conversation, to accelerate means to speed up. For instance, we are familiar with the acceleration of our car; the harder we apply our foot to the gas pedal, the faster we accelerate. The greater the acceleration, the greater the change in velocity over a given time. Acceleration is widely seen in experimental physics. In...

01:10Relative Motion Analysis - Acceleration
349
A slider-crank mechanism converts rotational motion from the crank into linear motion of the slider or vice versa. This mechanism consists of three main parts: the crank, the connecting rod, and the slider. The movement of the slider-crank is an example of general plane motion as the fluctuating angle between the crank and the connecting rod. Consider a segment AB where point A is at the end of the slider and point B is on the diametrically opposite end to point A, on a crack. The variance in...

7.7K
Acceleration is in the direction of the change in velocity, but it is not always in the direction of motion. When an object slows down, its acceleration is opposite to the direction of its motion. Although commonly referred to as deceleration, this causes confusion in our analysis as deceleration is not a vector, and does not point to a specific direction with respect to a coordinate system. Therefore, the term deceleration is not used. For example, when a subway train slows down, it...

01:20Variation in Acceleration due to Gravity near the Earth's Surface
2.4K
An object's apparent weight is its weight measured by a spring balance at its location. It is different from its true weight, the force with which the Earth pulls it, because of the Earth's rotation. Mathematically, an object's apparent weight equals its true weight minus the centripetal force that keeps it in a circular motion along with the Earth's surface every 24 hours.
The difference between the true and apparent weights is proportional to the square of the Earth's...

01:30Acceleration Vectors

In everyday conversation, accelerating means speeding up. Acceleration is a vector in the same direction as the change in velocity, Δv, therefore the greater the acceleration, the greater the change in velocity over a given time. Since velocity is a vector, it can change in magnitude, direction, or both. Thus acceleration is a change in speed or direction, or both. For example, if a runner traveling at 10 km/h due east slows to a stop, reverses direction, and continues their run at 10 km/h...
