Velocity and Position by Graphical Method01:34

Velocity and Position by Graphical Method

9.3K
Velocity and position can be calculated from the known function of acceleration as a function of time. The total area under the acceleration-time graph and the velocity-time graph gives the change in velocity and position, respectively. In the case of an airplane, its acceleration is tracked using the inertial navigation system. The pilot provides the input of the airplane's initial position and velocity before takeoff. The inertial navigation system then uses the acceleration data to...

Fluid Movement Between Compartments01:18

Fluid Movement Between Compartments

4.1K
The force applied by fluids against a surface, known as hydrostatic pressure, initiates the transfer of fluid among different compartments. Within our blood vessels, the blood's hydrostatic pressure is a result of the heart's pumping action. At the arteriolar end of capillaries, hydrostatic pressure (capillary blood pressure) exceeds the opposing colloid osmotic pressure created primarily by plasma proteins like albumin. This discrepancy in pressure propels plasma and nutrients from the...

Social Facilitation01:04

Social Facilitation

29.0K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Muscle Coordination and Action01:24

Muscle Coordination and Action

3.8K
Muscle coordination is a complex and finely tuned process essential for smooth and purposeful movements like flexion, extension, adduction, abduction, and rotation. The human body orchestrates the actions of various muscles working in concert, each with a specific role. Four functional types describe how muscles work together: agonist, antagonist, synergist, and fixator.
Agonists
Agonist muscles, often called prime movers, are the primary muscles responsible for producing a specific movement....

Absolute Motion Analysis- General Plane Motion

744
Visualize a drone, with its propellers spinning rapidly, hovering mid-air. The fascinating movements and operations of this drone can be comprehended by applying the principle of general plane motion.
As the drone's propellers rotate, an upward force is generated that counteracts the force of gravity, enabling the drone to lift off from the ground. This initial movement of the drone is along a straight path, representing a form of translational motion. In this phase, every point on the...

Movement Joints in Buildings01:27

Movement Joints in Buildings

483
Movement joints in buildings are essential design elements that accommodate inevitable motions caused by various factors such as temperature changes, moisture content variations, and structural deflections. These motions, if not considered in design and construction, can lead to unsightly or dangerous damage. Movement joints are incorporated in different forms to manage these stresses and allow materials to move without causing distress.
The simplest type of movement joints, working joints, are...

Area of Science:

  • Biomechanics
  • Human motor control
  • Neuroscience

Background:

  • Postural sway complexity and adaptive responses show controversial findings.
  • Understanding expertise in postural control is crucial for rehabilitation and performance.

Purpose of the Study:

  • To compare postural control performance and complexity between dancers and non-dancers.
  • To investigate the influence of visual information on balance in different expertise groups.

Main Methods:

  • 18 contemporary dancers and 30 non-dancers performed a 30s balance task on a stability platform.
  • Balance ability and dynamic characteristics were assessed with eyes open and closed.
  • Complexity of postural sway was analyzed using time-varying measures.

Main Results:

  • Dancers demonstrated superior balance ability compared to non-dancers only when their eyes were open.
  • Both groups performed worse with eyes closed, but dancers uniquely reduced their sway complexity.
  • Visual feedback significantly impacts postural control strategies in skilled individuals.

Conclusions:

  • Enhanced postural control in dancers is contingent upon visual information availability.
  • Expertise modulates the reliance on visual cues for maintaining balance.
  • Future research should explore sensory integration in diverse populations.
