What is Antiphase coordination?
In-phase and anti-phase movements represent two basic coordination modes with different characteristics: during in-phase movements, bilateral homologous muscle groups contract synchronously, whereas during anti-phase movements, they contract in an alternating fashion.
What is anti-phase motion?
During in-phase movements, participants synchronized one hand cycle with every metronome beat; during anti-phase movements, participants synchronized flexion of one hand with one metronome beat and extension of the other hand with the next beat.
What does in phase and anti-phase mean?
Wiktionary. antiphasenoun. A difference in phase (of two waves) of 180° antiphaseadjective. Describing a boundary between an ordered phase and a disordered or random phase.
What is meant by phase shift in physics?
Phase shift simply means that the two signals are at different points of their cycle at a given time. Phase shift is measured as the angle (in degrees or radians) between two points on a circle at the same time, demonstrating the progress of each wave through its cycle.
Does antiphase mean out of phase?
The amount by which the waves are out of phase with each other can be expressed in degrees from 0° to 360°, or in radians from 0 to 2π. If the phase difference is 180 degrees (π radians), then the two waves are said to be in antiphase.
What is meant by node and Antinode?
A node is a point along a standing wave where the wave has minimum amplitude. The opposite of a node is an anti-node, a point where the amplitude of the standing wave is at maximum. These occur midway between the nodes.
Why is it called a phase shift?
Any sine wave that does not pass through zero at t = 0 has a phase shift. The phase difference or phase shift as it is also called of a Sinusoidal Waveform is the angle Φ (Greek letter Phi), in degrees or radians that the waveform has shifted from a certain reference point along the horizontal zero axis.
What degree is antiphase?
noun Opposition of phase, or difference of phase amounting to one half period or 180 degrees.
